Spray Foam Insulation in Commerce, CA
Spray foam insulation in Commerce solves a problem that batt insulation can’t: the extreme radiant heat that builds up in homes surrounded by warehouses, truck routes, and acres of concrete. Most Commerce residences are modest 1940s–1960s single-family homes with little to no original wall insulation, and summer highs regularly push into the 90s°F without the marine layer cooling that coastal cities get. Closed-cell spray foam applied to attic rooflines and rim joists cuts that heat transfer dramatically, and it air seals at the same time. Call (562) 784-9031 and we’ll walk you through what your house actually needs.
Why Commerce Homes Are Different
Commerce is one of Southern California’s most industrialized cities. The overwhelming majority of its land area is covered by warehouses, distribution centers, and light manufacturing facilities along the I-5 and I-710 freight corridors, not residences. The small residential pockets that do exist consist largely of modest single-family homes built in the 1940s through the 1960s, tightly hemmed in by industrial zones. That means something specific for insulation work. These homes sit surrounded by hard surfaces, truck exhaust, and industrial heat output. Thermal conditions are worse than in neighboring residential cities like Downey or Montebello because the surrounding built environment radiates heat long after sunset. And because Commerce sits far enough inland to miss significant marine layer cooling, summer highs regularly reach the 90s°F. Homes built in the 1940s–1960s often have minimal original insulation or none at all in the walls, which makes the cooling load brutal. Our approach to Commerce work starts with acknowledging that: the house isn’t in a typical suburban setting, and the insulation strategy can’t be a copy-paste from a coastal job. The owner of Summit Insulation Long Beach has served Commerce since 2013 and assesses each home against what’s actually around it.
Our Main Commerce Services
Commerce homeowners call us most often about two things: an attic that’s baking the second floor, and a crawl space that’s pumping damp air up into the living area. Here’s what each involves in this city.
Attic Insulation in Commerce
In Commerce, attic insulation is the first line of defense against a roof that bakes all day. If your top floor runs 8–10 degrees hotter than the rest of the house by late afternoon, the attic is usually the culprit. We inspect the existing insulation level, check for rodent damage (common near warehouse-adjacent neighborhoods where rats and pigeons thrive), and recommend the right material for your roof pitch and venting. For a full breakdown of what attic work costs and how we do it in Commerce, see Attic Insulation in Commerce.
Crawl Space Encapsulation & Vapor Barrier in Commerce
Older Commerce homes often have vented crawl spaces that pull moisture from the soil and distribute it through the house all summer. That humidity makes the air feel heavier, forces your AC to work longer, and invites mold into floor framing. Encapsulation seals the crawl space with a vapor barrier and closes the vents, which stabilizes indoor humidity and protects the structure. For details on materials, price ranges, and how we install it in Commerce, see Crawl Space Encapsulation & Vapor Barrier in Commerce.

Spray Foam Insulation in Commerce
Spray foam insulation in Commerce addresses the single biggest thermal problem this city’s homes face: sustained, high radiant heat gain on structures that were never designed for modern cooling loads. Most Commerce houses date from the 1940s through the 1960s, an era when wall insulation was optional and often skipped entirely. Compounding that, Commerce sits inland enough to miss the marine layer that keeps Long Beach and Signal Hill cooler, so afternoon highs in the 90s are normal from June through September. The surrounding industrial landscape makes it worse: warehouses, tilt-up concrete buildings, and asphalt lots absorb solar energy all day and re-radiate it into the evening. Open-cell spray foam at the attic roofline creates an air barrier that stops hot attic air from pressing down into living spaces, while closed-cell foam at rim joists blocks both heat and moisture intrusion. The owner installs it himself, and he matches the foam type to your specific application rather than defaulting to whatever’s on the truck. Here’s the full Spray Foam Insulation breakdown.
Open-Cell Spray Foam
Signs you need it
Your upstairs feels stuffy and warm even after the AC has been running for an hour. The ceiling below the attic is warm to the touch in summer. You notice drafts near recessed lights or ceiling penetrations.
What it costs in Commerce
Open-cell spray foam in Commerce typically runs $1.80–$2.75 per board foot installed, with an attic roofline job often landing in the $3,400–$6,500 range for an average 1,200–1,800 sq ft home.
How we do it
We clear the attic, prep the roofline, and spray a continuous layer of open-cell foam directly onto the underside of the roof deck. The foam expands to fill gaps and seal penetrations. We then verify depth and coverage so there’s no thermal bridging at the rafters.
Closed-Cell Spray Foam
Signs you need it
You have a crawl space or rim joist area that stays damp. Your utility bills stay high year-round. You want the highest R-value per inch you can get in a limited cavity.
What it costs in Commerce
Closed-cell spray foam in Commerce typically costs $2.50–$4.00 per board foot, and a standard rim joist package for a 1,500 sq ft home usually lands between $1,500 and $3,200.
How we do it
We seal off the work area and apply closed-cell foam to the rim joist band or specified wall cavity. The foam cures into a rigid, vapor-resistant layer that acts as both insulation and air barrier. We trim any excess and leave the substrate clean.
Rim Joist Spray Foam
Signs you need it
You feel cold drafts near the base of exterior walls in winter. Your floors are cold even when the house is warm. You’ve seen signs of mice or rats near the foundation.
What it costs in Commerce
Rim joist spray foam in Commerce typically runs $1.50–$2.75 per board foot, with a full perimeter on a typical home landing between $1,200 and $2,800 depending on joist depth and access.
How we do it
We access the rim joist from inside the crawl space or basement. Each bay gets cleaned of debris, then we spray the foam across the entire band. After it cures, the rim joist is air sealed, which stops both drafts and rodent entry points.
Garage Ceiling Spray Foam
Signs you need it
Your garage is uncomfortably hot by afternoon, and heat bleeds into adjacent living spaces. You use the garage as a workshop or laundry area. The ceiling has no insulation or only thin batts.
What it costs in Commerce
Garage ceiling spray foam in Commerce typically runs $1,800–$3,600 for a standard two-car garage, depending on whether the space above is open attic or finished.
How we do it
We mask off the garage, protect the floor and any stored items, and spray the ceiling plane. If there’s living space above, we match the foam type to the thermal and acoustic needs. The result is a garage that stops acting as a heat reservoir.
What Spray Foam Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Open-cell spray foam (per board foot) | $1.80–$2.75 |
| Closed-cell spray foam (per board foot) | $2.50–$4.00 |
| Rim joist spray foam (full perimeter) | $1,200–$2,800 |
| Garage ceiling spray foam (two-car) | $1,800–$3,600 |
| Attic roofline open-cell (1,200–1,800 sq ft) | $3,400–$6,500 |
Is spray foam worth the price in Commerce?
In Commerce’s inland heat and industrial surroundings, yes for most homes with chronically hot attics or uninsulated rim joists. Spray foam air seals while it insulates, which addresses the drafts and heat bleed that batts alone can’t fix. Call (562) 784-9031 and we’ll tell you honestly if your house actually needs it.
Can you spray foam an attic that already has old insulation?
No, not without removing the old material first. Spray foam needs direct contact with the roof deck or framing to adhere and form an air barrier. We remove old insulation, clean the substrate, then spray. Call for a same-week assessment in Commerce.
Blown-In Insulation in Commerce
Blown-in insulation in Commerce is the workhorse solution for the city’s 1940s–1960s homes, many of which still have no wall insulation and only a thin, settled layer of attic fiberglass from decades ago. Because Commerce sits inland and misses the coastal marine layer, attic heat is a real cooling-cost driver from May through October. Blown-in cellulose or fiberglass fills irregular cavities and settles tightly around wiring, plumbing, and framing to create a continuous thermal layer. It’s also one of the most cost-effective ways to bring an older Commerce house up to current R-value recommendations without opening walls. The owner of Summit Insulation Long Beach handles the Blown-In Insulation install personally.
Blown-In Cellulose
Signs you need it
Your attic has less than 6 inches of existing insulation. You can feel heat radiating through the ceiling on summer afternoons. Your AC runs constantly but the house still feels stuffy.
What it costs in Commerce
Blown-in cellulose in Commerce typically runs $1,200–$3,000 for a standard 1,000–1,500 sq ft attic brought to R-38, depending on existing depth.
How we do it
We air seal the attic floor first, install baffles at the eaves to protect ventilation, then blow cellulose to the specified depth using a calibrated machine. We check density and depth with a ruler at multiple points so the R-value is real, not guessed.
Blown-In Fiberglass
Signs you need it
You prefer a material that won’t hold moisture as readily. Your attic has open framing where fiberglass’s light weight helps. You need a fast, clean top-up before summer.
What it costs in Commerce
Blown-in fiberglass in Commerce typically runs $1,100–$2,800 for an attic brought to R-38 in a standard single-family home.
How we do it
We prep the attic, seal penetrations, and blow loose-fill fiberglass to the required depth. We use Owens Corning or Johns Manville material and verify the coverage with depth markers. The job is usually done in a half day.
Dense-Pack Wall Insulation
Signs you need it
Your exterior walls feel cold in winter and warm in summer. You have empty wall cavities in a home built before 1970. You hear outside noise through the walls.
What it costs in Commerce
Dense-pack wall insulation in Commerce typically costs $3,500–$7,500 for a full exterior wall retrofit on a 1,200–1,800 sq ft home.
How we do it
We drill access holes through the exterior siding or interior drywall at each stud bay, then blow cellulose or fiberglass at high pressure until the cavity is densely packed. Holes are patched and finished. The difference in interior comfort is noticeable within days.
Blown-In Top-Up
Signs you need it
Your attic has insulation but it looks thin or settled. Your energy bills have crept up over the last few years. You can see bare spots or uneven coverage.
What it costs in Commerce
A blown-in top-up in Commerce typically runs $700–$1,800 depending on how much additional material is needed to reach R-38.
How we do it
We inspect the existing insulation, note any contamination or moisture problems, and blow additional material over the top to reach the target R-value. This is a fast, high-value job that can cut cooling costs immediately.
What Blown-In Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Blown-in cellulose attic (to R-38) | $1,200–$3,000 |
| Blown-in fiberglass attic (to R-38) | $1,100–$2,800 |
| Dense-pack wall retrofit (full house) | $3,500–$7,500 |
| Blown-in top-up | $700–$1,800 |
How long does blown-in insulation last in Commerce’s heat?
Cellulose and fiberglass both last 20–30 years or more, but settlement and rodent activity can reduce effectiveness much sooner. In Commerce, attic rodents are common near warehouse-adjacent blocks, so we recommend checking depth every few years. Call (562) 784-9031 for a free attic assessment.
Is blown-in better than batts for an old Commerce house?
For most older Commerce homes, yes. Blown-in material fills irregular framing and around old wiring where batts leave gaps. It installs without tearing out drywall. Call us and we’ll tell you which approach matches your particular house.
Radiant Barrier Installation in Commerce
Radiant barrier installation in Commerce targets a heat source that conventional insulation can’t fully address: direct solar gain on a roof that bakes in the inland LA Basin sun. Commerce misses the marine layer cooling that coastal cities receive, so roof surfaces get brutally hot in summer. A radiant barrier reflects radiant heat away from the attic before it ever reaches the insulation below, which means the house doesn’t have to fight as much heat from above. For older Commerce homes with limited roof insulation, a radiant barrier can cut attic temperatures enough to make a real difference in upstairs comfort. We offer Radiant Barrier Installation as a standalone or add-on service, which most insulation-only contractors skip entirely.
Attic Radiant Barrier
Signs you need it
Your attic feels like an oven by mid-afternoon. The upstairs runs noticeably hotter than the downstairs. Your AC has to recover every evening just to reach a comfortable temperature.
What it costs in Commerce
An attic radiant barrier in Commerce typically runs $1,500–$3,500 for a standard single-family home depending on attic size and accessibility.
How we do it
We staple a reinforced foil radiant barrier to the underside of the roof rafters, leaving an air gap for the reflective surface to work. We work around existing ventilation and framing. The attic temperature drops measurably on the first hot day.
Radiant Barrier Foil
Signs you need it
You want a lower-cost radiant barrier option. Your attic has simple, accessible rafter framing. You’re adding insulation anyway and want the reflective benefit at the same time.
What it costs in Commerce
Radiant barrier foil installed over existing attic insulation in Commerce typically runs $700–$1,500 for a standard attic.
How we do it
We roll out the foil over the top of the existing attic insulation, overlapping seams and cutting around penetrations. This method reflects heat from the attic floor plane and is fast to install.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing or building new and want radiant protection at the deck level. Your attic is finished or used for storage. You want maximum heat rejection at the source.
What it costs in Commerce
Radiant barrier roof deck in Commerce typically costs $1,800–$4,500 for a standard home, more if roof access is complex.
How we do it
We install the radiant barrier against the roof deck during reroofing or as a retrofit where access permits. The reflective surface faces the attic air space to bounce heat out before it penetrates. This is most cost-effective during a planned reroof.
Radiant Barrier & Ventilation
Signs you need it
Your attic is hot and also poorly ventilated. You have ridge vent or soffit vent issues. You want a combined heat rejection and airflow solution.
What it costs in Commerce
A combined radiant barrier and ventilation package in Commerce typically runs $2,200–$5,000 depending on attic size and venting scope.
How we do it
We assess the existing vent path, then install the radiant barrier at the rafter or floor plane while ensuring soffit and ridge vents are clear and balanced. Proper ventilation makes the radiant barrier work harder because hot air has a path to escape.
What Radiant Barrier Installation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic radiant barrier (rafter-installed) | $1,500–$3,500 |
| Radiant barrier foil (over insulation) | $700–$1,500 |
| Radiant barrier roof deck | $1,800–$4,500 |
| Radiant barrier & ventilation package | $2,200–$5,000 |
Does a radiant barrier help in Commerce’s winter?
Minimally for heating, but it can reduce heat loss slightly by reflecting heat back into the attic at night. Its real value in Commerce is summer cooling-load reduction. Call (562) 784-9031 and we’ll explain exactly what it will and won’t do for your house.
Can I add a radiant barrier to an old Commerce house?
Yes. Older Commerce homes are often the best candidates because they typically have less roof insulation than new construction. As long as the attic is accessible, we can install a radiant barrier without disturbing your existing insulation.
Insulation Removal & Replacement in Commerce
Insulation removal and replacement in Commerce is often the necessary first step before any new insulation goes in. The city’s older homes, built in the 1940s–1960s, frequently have original insulation that’s settled, dust-filled, or contaminated by rodents drawn to the warm, sheltered attic space near warehouse-adjacent blocks. Rat and pigeon activity is common in Commerce, and contaminated insulation can’t be covered over. It has to come out. The owner of Summit Insulation Long Beach removes the old material, cleans the substrate, and installs the right replacement. Here’s the full Insulation Removal & Replacement process.
Attic Insulation Removal
Signs you need it
Your attic insulation is compacted, dusty, or less than 4 inches deep. You can see rodent droppings or nesting material in the insulation. The insulation smells musty or has visible mold staining.
What it costs in Commerce
Attic insulation removal in Commerce typically runs $1,500–$3,500 for a standard 1,000–1,500 sq ft attic, more if the space is cramped or heavily contaminated.
How we do it
We set up a high-powered vacuum system and remove all old insulation down to the attic floor. The material is bagged and disposed of properly. We then inspect the exposed framing for damage before any new insulation goes in.
Contaminated Insulation Removal
Signs you need it
You’ve had a rodent infestation in the attic. You see dark stains or droppings throughout the insulation. The attic has an ammonia-like odor.
What it costs in Commerce
Contaminated insulation removal in Commerce typically costs $1,800–$4,000 depending on contamination level and attic size.
How we do it
We remove all contaminated material under containment protocols to prevent spreading dust into the living space. The attic is then sanitized and deodorized before replacement insulation is installed. This phase gate protects your family’s air quality.
Vermiculite & Old Insulation Removal
Signs you need it
Your attic has vermiculite or unknown loose-fill material from the 1920s–1970s. You’re planning a remodel and need the attic clean for inspections. You want to rule out asbestos-containing material before any disturbance.
What it costs in Commerce
Vermiculite or old insulation removal in Commerce typically runs $2,000–$5,500 depending on material type, testing requirements, and abatement protocols.
How we do it
We take care to follow safe handling procedures for older materials and work with licensed testing when required. The material is removed carefully and the attic is prepared for new insulation. We never rush this step.
Insulation Replacement
Signs you need it
You’ve removed old insulation and need a full replacement. You want to switch from fiberglass batts to blown-in or spray foam. Your energy bills are high and the attic insulation is clearly past its useful life.
What it costs in Commerce
Full insulation replacement in Commerce typically runs $2,500–$6,500 depending on material choice and attic size, combining removal and new installation.
How we do it
After the old material is out and the attic is cleaned, we install the replacement insulation matched to your home’s needs. That could be blown-in cellulose, fiberglass batts, or spray foam at the roofline. The result is a clean, correctly insulated attic.
What Insulation Removal & Replacement Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic insulation removal | $1,500–$3,500 |
| Contaminated insulation removal | $1,800–$4,000 |
| Vermiculite & old insulation removal | $2,000–$5,500 |
| Full insulation replacement (remove + install) | $2,500–$6,500 |
Do I really need to remove old insulation before adding new in Commerce?
If it’s dry, uncontaminated, and just settled, a top-up may be fine. If there’s rodent waste, moisture, or it’s compacted to the point of losing R-value, removal first is the correct move. Call (562) 784-9031 and we’ll tell you what we’d do in our own house.
How long does insulation removal take in Commerce?
Most standard attic removals are done in one day. Contaminated or vermiculite jobs can take two to three days due to containment and careful handling. We’ll give you a realistic timeline at the estimate.
Attic Air Sealing in Commerce
Attic air sealing in Commerce addresses the silent drafts and pressure leaks that make a house feel uncomfortable no matter how much insulation it has. In older Commerce homes, the attic floor is full of penetrations: recessed lights, duct boots, top plates, plumbing vents, and a leaky attic hatch. Each one lets conditioned air escape into the attic and pulls hot, dusty attic air back down. In a city surrounded by industrial activity, that also means pulling in truck exhaust and warehouse dust. Air sealing stops that exchange. We do the Attic Air Sealing before any new insulation goes in, because sealing over insulation is backwards.
Attic Floor Air Sealing
Signs you need it
Your upstairs feels drafty even with the windows closed. You see dust streaks on insulation. Your energy bills are high despite decent insulation levels.
What it costs in Commerce
Attic floor air sealing in Commerce typically runs $800–$1,800 for a standard attic, depending on penetration count.
How we do it
We push back insulation at each penetration, seal with foam or caulk, then restore the insulation. The work is methodical and covers every leak path.
Top Plate & Penetration Sealing
Signs you need it
You have gaps where walls meet the attic floor. You can see daylight or feel drafts around plumbing vents and electrical penetrations. You want the full air barrier treatment.
What it costs in Commerce
Top plate and penetration sealing in Commerce typically runs $600–$1,400 as part of a full air sealing package.
How we do it
We seal the top plates at every interior and exterior wall intersection, then foam around every wire, pipe, and vent. This is the most impactful part of air sealing because the top plate runs the entire perimeter of the house.
Can Light & Duct Boot Sealing
Signs you need it
You have older recessed lights that are not IC-rated. Your ceiling around lights feels warm. You feel air moving around register boots in the ceiling.
What it costs in Commerce
Can light and duct boot sealing in Commerce typically costs $300–$800 for a typical home depending on fixture count.
How we do it
We seal around each fixture and duct boot with approved materials that won’t overheat. If you have non-IC-rated fixtures, we’ll discuss proper enclosures or replacement. The difference in ceiling temperature is noticeable immediately after.
Attic Hatch Sealing
Signs you need it
Your attic hatch or pull-down stairs are uninsulated and unsealed. You can feel a draft when standing beneath the hatch. Dust accumulates around the hatch frame.
What it costs in Commerce
Attic hatch sealing in Commerce typically costs $150–$400 including weatherstripping and an insulated cover.
How we do it
We install weatherstripping around the hatch frame and add an insulated cover on the attic side. This closes one of the largest single leak points in most older Commerce homes.
What Attic Air Sealing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Full attic floor air sealing | $800–$1,800 |
| Top plate & penetration sealing | $600–$1,400 |
| Can light & duct boot sealing | $300–$800 |
| Attic hatch sealing | $150–$400 |
Should I air seal before or after adding insulation in Commerce?
Always before. Air sealing needs direct access to the penetrations, which gets buried under new insulation. The correct sequence is air seal first, then insulate. Call (562) 784-9031 to schedule both as one job.
How much energy does air sealing save in Commerce?
It depends on how leaky your attic is, but sealed attic floors typically reduce HVAC energy use by 10–20% in older Commerce homes. The savings are especially noticeable during summer when the AC fights both heat and humidity.
Wall Insulation in Commerce
Wall insulation in Commerce is the least visible but often most needed upgrade for the city’s 1940s–1960s homes, many of which were built with empty wall cavities or nothing more than thin fiberboard sheathing. Commerce sits inland enough that summer heat radiates through walls long after the sun goes down, especially where homes border industrial lots that hold heat. The surrounding hard surfaces and truck traffic also mean noise intrusion through uninsulated walls. We do Wall Insulation that addresses both temperature and sound, using the right material for the cavity.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel warm to the touch in summer and cold in winter. You hear outside noise through the walls. Your home was built before 1970 with little or no wall insulation.
What it costs in Commerce
Injection foam wall insulation in Commerce typically runs $3,000–$7,000 for a full exterior wall retrofit on a standard single-family home.
How we do it
We drill small access holes into each stud bay and inject slow-rise foam that fills the cavity completely. The foam expands to fill gaps and seal around existing wiring. Holes are patched and touched up.
Drill & Fill Wall Insulation
Signs you need it
You have empty wall cavities and want a less expensive option than injection foam. You’re planning to reside or repaint and don’t mind patching. Your main concern is summer heat gain through the walls.
What it costs in Commerce
Drill and fill wall insulation in Commerce typically costs $2,800–$6,000 for a full house, depending on wall area and material choice.
How we do it
We drill access holes, blow in cellulose or fiberglass at moderate density, then patch the holes. This method works well for most older Commerce homes and provides an immediate comfort improvement.
Exterior Wall Insulation
Signs you need it
You’re already replacing siding or stucco and want to add insulation at the same time. You want continuous insulation to eliminate thermal bridging. You’re doing a major remodel.
What it costs in Commerce
Exterior wall insulation in Commerce typically runs $5,000–$12,000 as a standalone project, less if combined with siding replacement.
How we do it
We apply rigid foam board or mineral wool to the exterior sheathing before the new siding goes on. This creates a continuous thermal break that cavity insulation alone can’t achieve.
Interior Wall Soundproofing
Signs you need it
You live near the I-5 or I-710 and hear truck traffic inside. You have a shared wall or noisy neighbor. You want to reduce sound transfer between rooms.
What it costs in Commerce
Interior wall soundproofing in Commerce typically runs $1,500–$4,000 per wall depending on area and material choice.
How we do it
We install dense-pack cellulose or mineral wool insulation in the interior wall cavities, often paired with resilient channel or mass-loaded vinyl where sound reduction is the priority. The result is a noticeably quieter room.
What Wall Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Injection foam wall retrofit | $3,000–$7,000 |
| Drill & fill wall retrofit | $2,800–$6,000 |
| Exterior wall insulation | $5,000–$12,000 |
| Interior wall soundproofing (per wall) | $1,500–$4,000 |
Can you insulate the walls of an old Commerce house without tearing out drywall?
Yes, injection foam and drill-and-fill methods both access the wall cavity through small holes without removing drywall. The holes are patched after. Call (562) 784-9031 and we’ll tell you which approach fits your house and budget.
Why are my walls so hot in Commerce in the summer?
Uninsulated or minimally insulated wall cavities absorb radiant heat from the sun and the surrounding hard surfaces and release it into the house for hours after sunset. In Commerce’s inland climate, that’s a significant cooling load. Wall insulation breaks that heat path.
Attic Cleaning & Rodent Proofing in Commerce
Attic cleaning and rodent proofing in Commerce is a core service, not an afterthought, because this city’s industrial surroundings create perfect rodent habitat. The warehouses and distribution centers along the I-5 and I-710 corridors support large rat and pigeon populations that spill into nearby residential pockets. Older Commerce homes with gaps at the roofline, unsealed vents, or open soffit intersections become warm, sheltered nesting sites. Before new insulation goes in, the attic has to be cleaned, sanitized, and sealed against re-entry. Here’s the full Attic Cleaning & Rodent Proofing scope.
Attic Cleanout
Signs you need it
You see rodent droppings, nesting material, or food debris in the attic. There’s a persistent odor coming from overhead. Your insulation is visibly soiled or compressed.
What it costs in Commerce
An attic cleanout in Commerce typically costs $800–$2,000 depending on attic size and contamination level.
How we do it
We remove all debris, nesting material, and contaminated insulation. The attic is vacuumed clean to the deck. Then we inspect the space for damage and entry points.
Attic Sanitizing & Decontamination
Signs you need it
You’ve had a rodent problem and want the attic made safe before new insulation. There’s a lingering ammonia smell. You’re concerned about disease transmission from rodent waste.
What it costs in Commerce
Attic sanitizing and decontamination in Commerce typically runs $400–$1,000 for a standard attic after cleanout.
How we do it
We treat all surfaces with a hospital-grade disinfectant that neutralizes bacteria and odor. The space is fogged or sprayed to reach corners and rafter bays. After treatment, the attic is ready for new insulation.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in the walls or ceiling at night. You see rodent entry points around the roofline, vents, or utility penetrations. You’ve had repeated infestations.
What it costs in Commerce
Rodent proofing and exclusion in Commerce typically costs $600–$1,800 depending on entry point count and access difficulty.
How we do it
We seal every entry point with steel mesh, foam, or metal flashing, depending on the location. Vents get proper covers. The goal is a permanent exclusion, not a trap-and-repeat cycle.
Attic Restoration
Signs you need it
Your attic has been cleaned and sealed but needs structural or surface repairs. Ductwork or wiring has been damaged by rodents. You want the attic fully restored before insulation is reinstalled.
What it costs in Commerce
Attic restoration in Commerce typically runs $1,500–$4,000 depending on damage scope.
How we do it
We repair or replace damaged framing, ducting, and wiring protection, then install fresh insulation matched to your home’s needs. The attic ends up cleaner and better performing than before the infestation.
What Attic Cleaning & Rodent Proofing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic cleanout | $800–$2,000 |
| Attic sanitizing & decontamination | $400–$1,000 |
| Rodent proofing & exclusion | $600–$1,800 |
| Attic restoration | $1,500–$4,000 |
How common are attic rodents in Commerce?
Common. The surrounding warehouses and distribution facilities create large rodent populations that move into nearby homes through roof gaps and unsealed vents. We treat this as a standard part of attic work in Commerce, not a rare event. Call (562) 784-9031 for an inspection.
Should I clean the attic before or after rodent proofing in Commerce?
Both: clean and sanitize first to remove waste and odor, then seal entry points to prevent re-entry. Doing the proofing without the cleaning leaves contamination behind. We do both as one continuous job.

Home Energy Audit in Commerce
A home energy audit in Commerce gives you a data-driven picture of where your house is losing conditioned air and gaining heat, rather than a guess based on what a salesperson wants to sell you. In Commerce’s inland climate and industrial surroundings, the audit measures how hard your house works against summer heat gain and how leaky the envelope really is. The owner of Summit Insulation Long Beach performs the Home Energy Audit himself, and the recommendations come from the measurements, not from a script. This is the right starting point if you don’t know whether you need air sealing, insulation, or both.

Your energy bills are high but you don’t know where the air is leaking. You want a baseline number before and after improvements. Your house feels drafty in winter and hard to cool in summer.
What it costs in Commerce
A blower door test in Commerce typically costs $250–$500 as a standalone service, less when bundled with a full audit.
How we do it
We mount a calibrated fan in an exterior door frame and depressurize the house, then measure airflow at standard pressure. The number tells us exactly how leaky the envelope is. We can pinpoint the largest leaks with a smoke pencil or by hand.
Thermal Imaging Inspection
Signs you need it
Some rooms are consistently warmer or colder than others. You want to see where insulation is missing or settled. You suspect thermal bridging or air leaks at specific locations.
What it costs in Commerce
A thermal imaging inspection in Commerce typically runs $200–$400 and is usually part of a full home energy audit.
How we do it
We scan walls, ceilings, and floors with an infrared camera while the house is under blower door pressure. The camera shows missing insulation, air leaks, and moisture as temperature differences. You’ll see the images and know exactly what’s wrong.
Insulation Inspection
Signs you need it

What pushes the price up in Commerce is often how much old insulation has to come out first, since many homes here still have their original 1940s and 1950s material. Attic access and the depth needed to reach today’s R-value targets factor in as well. The price we quote is written out before any work begins.
FAQs About Insulation in Commerce, CA
How soon can you schedule a job in Commerce?
We typically schedule attic and wall jobs within a week of the estimate visit. Since most homes here sit close to industrial zones with limited street parking, we plan crew access in advance so the work can start on time.
Do I need a permit for insulation work?
Routine attic insulation, air sealing, and blown-in top-up work generally does not require a separate permit. We document the R-value installed and the areas treated so the work is recorded clearly.
How does the written estimate work?
We inspect the attic and walls in person and measure the actual square footage before quoting a price. That number is given to you in writing before work begins, and it does not change once the crew starts the job.
Do you serve areas near Commerce?
Yes, we work throughout the surrounding communities as well. The same inspection and pricing process applies whether your home sits near a warehouse corridor or further into a residential pocket.
What happens to the old insulation you remove?
We bag and haul away old fiberglass or rock wool from the attic, much of it original to 1940s and 1950s construction. The attic floor is left clean before any new insulation goes in.
