Spray Foam Insulation in Compton, CA
Spray foam insulation in Compton solves a problem that batt insulation cannot: sealing the thermal envelope of 1940s and 1950s stucco-over-wood-frame homes against 90°F afternoon heat that builds up fast once the marine layer burns off. Most Compton attics we open have settled fiberglass at R-5 or less, plus dozens of air leaks where wall top plates meet attic drywall. Closed-cell Spray Foam Insulation seals those leaks and creates an air barrier in one pass, which is why Compton homeowners with high July-to-September SCE bills call us at (562) 784-9031.
Why Compton Homes Are Different
Compton’s housing stock was mostly built between 1948 and 1962, a period when California tract builders rarely included wall cavity insulation. That means walls on many blocks across the city are empty cavities with only stucco, wood sheathing, and drywall separating conditioned air from 90°F outdoor heat. The city sits far enough inland that the cooling marine layer retreats by late morning, leaving flat rooftops and dense asphalt streets to bake until evening. Insulation here is primarily a cooling problem: an underinsulated attic in Compton translates directly to SCE bills that spike during summer heat events. We also pull attic hatches on Compton’s older blocks and find original rock wool compressed to less than R-5, sometimes with knob-and-tube wiring still present, which requires documentation and clearance before any blown-in attic insulation can be installed under California code.
Our Main Compton Services
Most Compton homeowners call us first about two things: an attic that is desperately thin on insulation, and a crawl space that is pumping damp air up through the floorboards. Here is what those jobs look like here.
Attic Insulation in Compton
Original 1950s fiberglass batts in Compton attics have compressed to a fraction of their rated R-value, often measuring R-5 or worse when we test them. The fix on most of these bungalows is a full removal of degraded material followed by blown-in top-up to R-38 or higher, and we always check for knob-and-tube wiring before we start. Attic Insulation in Compton work turns a 120°F attic into a stable thermal buffer that keeps bedrooms directly underneath from broiling by 4 p.m.
Crawl Space Encapsulation & Vapor Barrier in Compton
Homes near Compton Creek and the city’s lower-lying blocks frequently hold moisture in the crawl space, and that damp air rises into living areas year round. We install full encapsulation with a heavy vapor barrier that stops soil moisture at the source. Crawl Space Encapsulation & Vapor Barrier in Compton also lowers indoor humidity enough that the air conditioner runs shorter cycles, which matters for older homes with undersized ducts.

Spray Foam Insulation in Compton
Compton’s postwar bungalows leak air through dozens of gaps: around plumbing stacks, where interior walls sit on top plates, behind can lights, and along the attic hatch. Fiberglass and cellulose slow heat transfer, but they do not stop air movement. Closed-cell spray foam does both, and it is the single most effective upgrade for Compton homes where rooms run five to eight degrees warmer than the thermostat setting during summer afternoons. We install open-cell in vented attics, closed-cell against roof decks and rim joists, and targeted foam where the largest leaks tested during a blower door reading. Summit Insulation Long Beach has served Compton since 2013, and the owner runs every spray foam job as lead installer, so the person who quotes your job is the one spraying it.
Open-Cell Spray Foam
Signs you need it
Your upstairs rooms stay hot long after sunset, and your SCE bill climbs every July. You can feel a draft near the attic hatch even with the door closed. Insulation exists in the attic, but it measures under R-15 when we core-sample it.
What it costs in Compton
Open-cell spray foam in Compton typically runs $1.10 to $1.90 per board foot installed, which puts most full attic jobs on these smaller bungalows between $2,800 and $5,200.
How we do it
We mask off the attic access, run a hose from the rig, and spray the underside of the roof deck and gable walls to a confirmed depth. The foam expands and sets within minutes, filling irregular cavities that batts cannot reach. We leave ventilation as designed and confirm depth with probes before we pack up.
Closed-Cell Spray Foam
Signs you need it
You want the highest R-value per inch you can get in a low-clearance attic or on a roof deck. Your attic has moisture staining on framing that suggests humid air is condensing against the roof sheathing. You plan to use the attic for storage and want an air barrier you can build around.
What it costs in Compton
Closed-cell spray foam in Compton runs $1.70 to $2.80 per board foot installed, so a typical attic or rim joist package lands between $3,800 and $7,000 depending on square footage and depth.
How we do it
Closed-cell goes on in lifts, which is the only safe way to build depth without overheating the substrate. We spray the target surface to the specified inches, then verify depth and density before the job is done. The material cures rigid and adds structural racking strength to older framing.
Rim Joist Spray Foam
Signs you need it
First-floor rooms feel drafty even with the windows closed. You see gaps around the top of the foundation wall when you look up from the crawl space. Heating costs are noticeably high for such a small home.
What it costs in Compton
Rim joist spray foam in Compton usually runs $1,400 to $2,200 for a typical 1,200-square-foot bungalow for all four foundation sides.
How we do it
We work from the crawl space or basement edge, spraying each rim joist bay with closed-cell foam to create a continuous air and thermal break. We catch the band joist and the first two inches of the subfloor edge. The result is a sealed perimeter that stops stack-effect drafts.
Garage Ceiling Spray Foam
Signs you need it
A bedroom sits above or adjacent to the garage and never cools down in summer. The garage ceiling has exposed framing and either no insulation or thin batts compressed against drywall. Car exhaust smells are migrating into the house.
What it costs in Compton
Garage ceiling spray foam in Compton typically falls between $1,800 and $3,200 for a single-car garage and $2,600 to $4,400 for a two-car garage.
How we do it
We cover the vehicles and work area, then spray open-cell foam across the garage ceiling cavity to full depth. The foam seals around wiring and plumbing penetrations at the same time, which kills both heat gain and fume transfer.
What Spray Foam Insulation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Open-cell attic spray foam (1,000 sq ft) | $2,800 – $5,200 |
| Closed-cell attic or roof deck | $3,800 – $7,000 |
| Rim joist sealing (entire perimeter) | $1,400 – $2,200 |
| Garage ceiling spray foam (single car) | $1,800 – $3,200 |
| Two-car garage ceiling spray foam | $2,600 – $4,400 |
Is spray foam worth the extra cost in Compton?
For most Compton homes, yes. Closed-cell foam does the work of two products by sealing air and insulating, and it stops the air leaks that make these older bungalows so expensive to cool. Call (562) 784-9031 and we will tell you honestly whether open-cell would do the job.
Can you spray foam an old Compton attic without removing existing insulation?
No, not directly onto old material. We remove degraded batts first so the foam can adhere to the actual roof deck or framing. On attic floors we recommend air sealing and blown-in insulation instead; foam belongs on the roofline, rim joists, and walls.
Blown-In Insulation in Compton
Blown-in insulation is the workhorse fix for Compton homes because most of these postwar bungalows were built with empty wall cavities and thin attic batts that have compressed to near nothing since the 1950s. We blow Blown-In Insulation into open attics for fast top-ups to current code levels, and into closed wall cavities through small holes for dense-pack retrofits that never touch the stucco. An R-38 attic top-up on a Compton two-bedroom typically runs under $2,000 before any rebate, and it changes how the whole house feels by the following afternoon.
Blown-In Cellulose
Signs you need it
Your attic measures R-5 to R-10 and you want a dense, sound-absorbing material that fills oddly shaped joist bays. You like the idea of using recycled paper treated with borate. Your upstairs rooms overheat by mid-afternoon every summer day.
What it costs in Compton
Blown-in cellulose in Compton typically runs $1.60 to $2.40 per square foot installed, so a full attic top-up on a small bungalow starts around $1,500.
How we do it
We run a hose from the truck, break open the GreenFiber bales, and blow the material to the exact depth specified in inches. We check for knob-and-tube wiring and fixture clearance first. The material settles to its rated depth and fills the bays completely around blocking and bracing.
Blown-In Fiberglass
Signs you need it
You want a lighter-weight material that will not settle as much as cellulose over time. Your attic has good air sealing already and you just need thermal coverage. The joist bays are standard depth and wide open.
What it costs in Compton
Blown-in fiberglass in Compton runs $1.40 to $2.20 per square foot installed, with most 1,000-square-foot attics landing between $1,400 and $2,200.
How we do it
We lay down cavity guards if needed, then blow Owens Corning fiberglass to the specified depth measured in multiple spots with a depth gauge. The lighter material is fast to install and holds its loft in dry attic conditions. We sweep trim and access areas before leaving.
Dense-Pack Wall Insulation
Signs you need it
Your exterior walls feel cold in winter and hot to the touch in summer. The stucco is original with no evidence of injection holes drilled at the time of a prior retrofit. You want to keep the exterior look intact.
What it costs in Compton
Dense-pack wall insulation in Compton typically runs $2.50 to $3.80 per square foot of wall area installed, which puts most whole-house retrofits between $3,200 and $6,500.
How we do it
We drill small access holes through stucco or drywall at each stud bay, then inject cellulose at high density until the cavity reaches the target pounds per cubic foot. We probe every third bay to verify fill, then patch the holes to a smooth finish. The process takes one to two days.
Blown-In Top-Up
Signs you need it
You already have batt insulation but it reads R-8 or lower in multiple test spots. The attic has no moisture or rodent damage, so removal is unnecessary. You want the fastest, least disruptive upgrade available.
What it costs in Compton
Blown-in top-up in Compton runs $1.20 to $1.90 per square foot for the additional material and install, so a top-up from R-10 to R-38 on a 1,000-square-foot attic costs between $1,200 and $1,900.
How we do it
We verify the existing insulation is dry and uncontaminated, mark target depth lines on rafters, and blow fresh material directly on top. No removal, no tear-out, no mess. The whole job usually takes half a day.
What Blown-In Insulation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Blown-in cellulose attic top-up | $1,500 – $2,400 |
| Blown-in fiberglass attic top-up | $1,400 – $2,200 |
| Dense-pack wall retrofit (whole house) | $3,200 – $6,500 |
| Blown-in top-up only (R-10 to R-38) | $1,200 – $1,900 |
How much can I save on cooling with blown-in attic insulation in Compton?
Most Compton homeowners see a 15 to 25 percent drop in peak summer cooling costs after going from R-5 to R-38, depending on how leaky the house is. Combining the top-up with air sealing pushes savings higher. Call (562) 784-9031 for a free attic assessment.
Does blown-in insulation qualify for free installation through SCE or SoCalGas programs in Compton?
Many Compton households meet the income thresholds for the Energy Savings Assistance program, which can cover the full cost of attic insulation through a participating contractor. We walk you through the enrollment paperwork and then do the install. It costs nothing to check eligibility.
Radiant Barrier Installation in Compton
A radiant barrier in Compton attacks the problem batts and blown-in material cannot: heat radiating off a roof deck that hits 150°F by mid-afternoon. For homes where the sun pounds flat or low-slope rooftops all summer, Radiant Barrier Installation reflects that radiant heat before it ever reaches the insulation layer. We install foil-faced radiant barrier under the rafters of Compton attics, usually combined with an insulation top-up, and the drop in attic temperature is measurable the same day.
Attic Radiant Barrier
Signs you need it
Your attic is 140°F or hotter on July afternoons even with R-30 insulation installed. Bedrooms directly under the roof deck stay warm all night. Your AC runs almost continuously from noon to 8 p.m.
What it costs in Compton
Attic radiant barrier in Compton typically runs $0.80 to $1.30 per square foot installed, so a 1,000-square-foot attic lands between $800 and $1,300.
How we do it
We staple perforated reflective foil across the underside of the rafters, leaving a small air gap at the ridge and eaves for ventilation. The foil faces inward to reflect heat back toward the roof deck. We overlap seams and tape the major edges for a continuous reflective plane.
Radiant Barrier Foil
Signs you need it
You want the lowest-cost summer heat upgrade available. Your attic has open rafters without finish materials. You are planning to add insulation later and want this done first.
What it costs in Compton
Standalone radiant barrier foil in Compton runs $0.60 to $1.00 per square foot installed, generally $600 to $1,000 on these bungalows.
How we do it
We install heavy-duty foil across the rafter faces using staples and cap fasteners, keeping the reflective surface dust-free and facing the attic interior. We work around existing wiring and leave the required clearance around non-IC-rated fixtures. The job is done in a few hours on most Compton homes.
Radiant Barrier Roof Deck
Signs you need it
Your roof deck is the hottest surface in the house and you are adding or replacing roof sheathing anyway. You want an option that works even if you later spray foam the roofline. The attic is vented and dry.
What it costs in Compton
Roof deck radiant barrier in Compton runs $0.80 to $1.20 per square foot when installed as part of an insulation package, with most jobs between $800 and $1,200 for these smaller attics.
How we do it
We attach foil-faced sheathing or apply reflective foil directly to the underside of the roof deck before insulation goes in. The barrier faces inward, with clearance maintained at the ridge. This method reduces the surface temperature of insulation below it by 15 to 25 degrees in Compton’s summer conditions.
Radiant Barrier & Ventilation
Signs you need it
Your attic stays hot even with ridge and eave vents working. You want the combined effect of reflective foil plus balanced airflow. SCE summer bills are the main trigger for the call.
What it costs in Compton
Combined radiant barrier and ventilation in Compton runs $1,500 to $2,600 for a typical bungalow when both upgrades are installed together.
How we do it
We install the radiant barrier first, then check and balance the attic ventilation with additional eave or ridge venting where needed. The two upgrades work together: ventilation removes hot air, and the foil stops most radiant heat from entering the space in the first place.
What Radiant Barrier Installation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Attic radiant barrier (1,000 sq ft) | $800 – $1,300 |
| Standalone radiant barrier foil | $600 – $1,000 |
| Roof deck radiant barrier | $800 – $1,200 |
| Radiant barrier plus ventilation | $1,500 – $2,600 |
Does a radiant barrier make sense with blown-in insulation in Compton?
Yes, they solve different problems. Blown-in insulation slows conductive heat transfer while a radiant barrier reflects radiant heat off the roof deck. In Compton’s hot inland climate, the combination reduces attic temperatures more than either upgrade alone. Call (562) 784-9031 for a specific recommendation.
Will a radiant barrier ruin my roof shingles in Compton heat?
No. Radiant barriers installed on the underside of rafters do not affect shingle temperatures enough to shorten roof life in Compton’s climate. Proper ventilation at the ridge and eaves keeps the air moving above the foil where it matters.
Insulation Removal & Replacement in Compton
Compton attics and walls from the 1950s hold more than just thin insulation. We regularly pull out compressed rock wool, old fiberglass matted down with rodent droppings, and material that has absorbed decades of humidity from the city’s marine mornings. Insulation Removal & Replacement is the step that makes new insulation worth installing. You cannot blow fresh material over contaminated or degraded substrate and expect it to perform. We remove, sanitize, and then rebuild the thermal layer from scratch.
Attic Insulation Removal
Signs you need it
The existing material is compressed to R-5 or less and is not worth topping up. You see heavy dust accumulation, old nesting material, or staining on the batts. You are preparing for air sealing and want a clean substrate first.
What it costs in Compton
Attic insulation removal in Compton typically runs $1.20 to $2.00 per square foot, so a 1,000-square-foot attic lands between $1,200 and $2,000.
How we do it
We set up a commercial vacuum and route the hose to a sealed container outside, then remove the old material down to the drywall. We bag and dispose of everything off site. The attic is left clean enough to inspect wiring and top plates for air sealing.
Contaminated Insulation Removal
Signs you need it
There are rodent droppings scattered through the attic, or you see urine staining on the insulation and framing. The material smells when the attic heats up in summer. You have had a leak or pest issue that compromised the batts.
What it costs in Compton
Contaminated insulation removal in Compton typically runs $1.80 to $2.80 per square foot because of the protective protocols, landing at $1,800 to $2,800 for most bungalows.
How we do it
We suit up in protective gear, bag the contaminated material by hand where needed, and vacuum the rest. After removal we sanitize the exposed surfaces and treat for the source of the contamination. Only then do we bring in new insulation.
Vermiculite & Old Insulation Removal
Signs you need it
You have loose grayish-brown material in the attic that looks like pebbles, which is common in homes built before 1960 in Compton. You want it tested and potentially removed before any other work. The house has old wiring you need inspected.
What it costs in Compton
Vermiculite and old insulation removal in Compton runs $2.00 to $3.50 per square foot when testing and specialized handling are required.
How we do it
We sample the material first and, if testing indicates asbestos, we bring in licensed abatement specialists rather than touching it ourselves. For non-regulated material we vacuum and bag it using dust containment barriers. You get documentation of what was removed and where it went.
Insulation Replacement
Signs you need it
The old insulation cannot be saved and you want the attic brought to current code levels in one job. You want air sealing, new insulation, and possibly a radiant barrier done at the same time. Your rooms never hold temperature consistently.
What it costs in Compton
Insulation replacement in Compton, including removal, air sealing, and new blown-in insulation, typically runs $3,500 to $6,000 for a small bungalow.
How we do it
We remove the old material, seal the top plates and penetrations, then install new blown-in or batt insulation to the target R-value. We finish with a depth check and a walkthrough. The whole sequence takes one to two days on most Compton homes.
What Insulation Removal & Replacement Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Attic insulation removal only | $1,200 – $2,000 |
| Contaminated insulation removal | $1,800 – $2,800 |
| Vermiculite or old material (tested, regulated) | $2,000 – $3,500 |
| Full replacement with air sealing and new insulation | $3,500 – $6,000 |
Can you replace our insulation without removing the old stuff in Compton?
Only if the old material is dry, uncontaminated, and not compressed beyond usefulness. In most Compton attics from the 1950s and early 1960s, removal is the right call before adding new material. We will tell you if a simple top-up will suffice.
How long does insulation removal and replacement take in Compton?
Most Compton homes are between 900 and 1,400 square feet, and full attic removal plus new insulation takes one to two days. Dense-pack wall work can add another day. We keep the work area sealed and clean throughout. Call (562) 784-9031 to schedule a walkthrough.
Attic Air Sealing in Compton
The single largest energy defect in Compton homes is not missing insulation; it is the air leaks between the house and the attic. Summer afternoons pull conditioned air out through these gaps while hot attic air is drawn in through lower leaks around doors and the crawl space. Attic Air Sealing closes the bypasses at the top plates, plumbing stacks, can lights, and the attic hatch. Done before insulation goes in, it makes every other upgrade perform closer to its rated spec.
Attic Floor Air Sealing
Signs you need it
You can feel air moving around the attic hatch. The insulation has dark dust stains on the underside, which is air carrying dust through the material. Rooms never hold a set temperature.
What it costs in Compton
Attic floor air sealing in Compton runs $800 to $1,500 for a typical bungalow, depending on how many penetrations we find.
How we do it
We pull back loose insulation where needed and seal every penetration through the attic floor with foam, caulk, or rigid material as appropriate. Wiring holes, plumbing vents, and interior wall top plates get treated. We work systematically so nothing is missed.
Top Plate & Penetration Sealing
Signs you need it
Smoke from a candle held near baseboards drifts upward toward the attic. Interior walls feel warm to the touch. The home smells dusty all year.
What it costs in Compton
Top plate and penetration sealing in Compton typically runs $600 to $1,100 as part of a broader air sealing package.
How we do it
We locate the top plates above each interior wall and run a continuous seal with foam or caulk. Plumbing and wiring penetrations get the same treatment. The work happens entirely from the attic side, so there is no dust inside the house.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights in the ceiling feel hot and you can see light gaps around their trims. Air comes out of the register when the system is off. Dust lines appear on the ceiling around fixtures.
What it costs in Compton
Can light and duct boot sealing in Compton runs $400 to $900 for a typical home with six to twelve fixtures and runs.
How we do it
We build or install rated enclosures around non-IC can lights, then seal the boots where ducts meet the ceiling drywall. For fixtures that cannot be covered, we maintain required clearance and seal what can be sealed safely. This one step often makes the biggest measurable difference on a blower door retest.
Attic Hatch Sealing
Signs you need it
You can see daylight around the attic access panel. The hatch feels hot in summer and cold in winter. Dust collects on the hatch frame.
What it costs in Compton
Attic hatch sealing in Compton typically runs $150 to $300, often bundled with other air sealing work.
How we do it
We install a weatherstripping gasket around the hatch frame, add insulation to the panel itself, and secure the latch so the seal compresses tightly. A sealed hatch stops a chimney of conditioned air from escaping into the attic year round.
What Attic Air Sealing Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Attic floor air sealing (full) | $800 – $1,500 |
| Top plate and penetration sealing | $600 – $1,100 |
| Can light and duct boot sealing | $400 – $900 |
| Attic hatch sealing | $150 – $300 |
Do I need air sealing before adding insulation in Compton?
Yes. Blowing insulation over unsealed penetrations is like wearing a jacket with the zipper open. Air still moves through, carrying heat and moisture. Seal first, then insulate, and the material performs as intended. Call (562) 784-9031 to book an assessment.
How much can air sealing save on my Compton energy bill?
Typical savings after air sealing plus an insulation top-up run 15 to 30 percent on annual heating and cooling for an older Compton home. The blower door test before and after gives you hard numbers rather than guesses.
Wall Insulation in Compton
Compton’s original stucco bungalows were almost never built with wall insulation, which means your exterior walls are likely empty cavities. That is the single biggest comfort problem we find behind the walls of homes built in the 1950s. Wall Insulation in Compton means drilling and filling those cavities with dense-pack material or injecting foam, which turns a hollow shell into a true thermal envelope. The work is done from the interior or exterior with small holes that get patched to invisible.
Injection Foam Wall Insulation
Signs you need it
Your walls feel like they radiate heat inward all summer. The stucco is original and you want to preserve it. There is no evidence of a previous retrofit.
What it costs in Compton
Injection foam wall insulation in Compton runs $3.00 to $4.50 per square foot of wall area installed, so a typical 1,200-square-foot bungalow lands between $3,600 and $5,400.
How we do it
We drill small holes at each stud bay from the interior or exterior, then inject slow-rise foam that fills the cavity without over-pressurizing the stucco. The holes get patched and painted to match. The job takes one to two days for a whole house.
Drill & Fill Wall Insulation
Signs you need it
You want a cellulose-based wall retrofit at a more accessible price than foam. The wall cavities are standard 2×4 depth and accessible from one side. You have no moisture damage in the wall.
What it costs in Compton
Drill and fill wall insulation in Compton typically runs $2.50 to $3.80 per square foot of wall area, which puts a full bungalow between $3,000 and $4,600.
How we do it
We drill access holes through the drywall or stucco at every stud bay, then dense-pack the cavity with cellulose until it reaches the target density. We probe each bay to confirm fill and patch the holes smooth. The whole house can be done in one long day.
Exterior Wall Insulation
Signs you need it
You are doing a full remodel that includes new siding or stucco. The wall cavities are open and you want the highest-value insulation installed while the sheathing is exposed.
What it costs in Compton
Exterior wall insulation during an open-wall remodel in Compton runs $1.20 to $2.50 per square foot of wall area, depending on material and depth.
How we do it
We install batts or blown-in material directly into the open cavities before the new sheathing goes on. This is the cleanest and cheapest way to insulate walls, but it only works during a renovation. We coordinate with your general contractor.
Interior Wall Soundproofing
Signs you need it
You hear every conversation through interior walls. A bedroom shares a wall with a bathroom or mechanical closet. You want mineral wool batts for both thermal and acoustic separation.
What it costs in Compton
Interior wall soundproofing in Compton runs $1.80 to $3.00 per square foot of wall area installed.
How we do it
We open the walls or work during an existing remodel, install Rockwool or dense-packed cellulose in the cavities, and re-close with the finish material. The mass and density of mineral wool make it our first choice for sound control between rooms.
What Wall Insulation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Injection foam wall insulation (whole house) | $3,600 – $5,400 |
| Drill and fill cellulose walls | $3,000 – $4,600 |
| Open-wall batt insulation (remodel) | $1,200 – $2,500 |
| Interior soundproofing (per room) | $1,800 – $3,000 |
Can you insulate Compton walls without removing the stucco?
Yes. Drill and fill and injection foam methods work from the interior or through small exterior holes, leaving the stucco intact. We patch the access points to match the existing finish. Call (562) 784-9031 to find out which one fits your walls.
How do I know if my Compton walls are actually empty?
We use a small borescope camera through a 1/4-inch hole to look inside a cavity. Most homes built before 1965 in Compton have either nothing or a thin layer of failed paper-faced batts. The inspection takes ten minutes.
Attic Cleaning & Rodent Proofing in Compton
Before new insulation goes in, the attic needs to be clean and sealed against the rats and mice that move through Compton’s older blocks in the cool season. Attic Cleaning & Rodent Proofing is the step that protects the investment. We remove contaminated material, sanitize the space, and seal every exterior entry point so the new insulation does not become a rodent habitat within six months.
Attic Cleanout
Signs you need it
There are old nest materials, scattered droppings, and debris in the attic. The insulation has been flattened by animal traffic. You can smell something stale when the house warms up.
What it costs in Compton
Attic cleanout in Compton typically runs $800 to $1,500 for a typical bungalow, depending on volume and contamination level.
How we do it
We remove all loose debris, old nests, and compromised material by hand and vacuum. We dispose of everything off site. The attic is left clean and ready for inspection of wiring and framing.
Attic Sanitizing & Decontamination
Signs you need it
Rodents have been active and you want the biological residue neutralized. There is urine staining on insulation or wood. You are preparing the attic for new insulation and want a clean substrate.
What it costs in Compton
Attic sanitizing and decontamination in Compton runs $500 to $1,000 for most single-story homes.
How we do it
After removal, we treat the exposed surfaces with an enzyme-based sanitizer that breaks down organic residue and neutralizes odor. We fog the space if needed and let it ventilate. The result is an attic that does not smell and will not attract new pests.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night in the dry season. You have found droppings in the attic. The house has gaps at the roofline, vents, or plumbing penetrations.
What it costs in Compton
Rodent proofing and exclusion in Compton typically runs $700 to $1,400 for a full exterior perimeter, depending on how many entry points we need to seal.
How we do it
We inspect the entire roofline and foundation perimeter, then seal every opening larger than a dime with steel mesh, hardware cloth, and sealant. We pay special attention to gable vents, eave returns, and pipe penetrations. The work prevents re-entry before new insulation goes in.
Attic Restoration
Signs you need it
The attic has been cleaned and sealed, and now you want it insulated and finished as if it were new. You want one call to handle the entire sequence from contamination to completed thermal upgrade.
What it costs in Compton
Full attic restoration in Compton, including cleanout, sanitizing, exclusion, and new blown-in insulation, typically runs $2,800 to $4,800 for a small bungalow.
How we do it
We sequence the whole job: cleanout first, then sanitizing and exclusion, then air sealing, then new insulation. The owner runs the crew and checks each phase. The attic ends up cleaner, drier, and better insulated than it has been since the house was built.
What Attic Cleaning & Rodent Proofing Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Attic cleanout only | $800 – $1,500 |
| Attic sanitizing and decontamination | $500 – $1,000 |
| Rodent proofing and exclusion | $700 – $1,400 |
| Full attic restoration | $2,800 – $4,800 |
Do I need to remove the old insulation after rodents have been in my Compton attic?
In most cases, yes. Rodent urine and droppings contaminate the material and it cannot be cleaned in place. Removing it, sanitizing the framing, and installing fresh insulation is the only way to eliminate the odor and health concern. Call (562) 784-9031 for a cleanout quote.
How do rats get into Compton attics?
Rats enter through gable vents, eave gaps, roof transitions, and plumbing stacks. They need an opening about the size of a quarter. We seal every one we find with steel mesh and exclusion material that they cannot chew through.

Home Energy Audit in Compton
Before you spend a dollar on insulation in Compton, you should know exactly where the house is bleeding energy. A Home Energy Audit gives you the data: a blower door test that measures air leakage, thermal imaging that shows where walls are empty, and a duct leakage test that reveals how much of your conditioned air is escaping into the attic. The report becomes a prioritized list of upgrades, and for many Compton households the first step is checking ESA program eligibility through SCE and SoCalGas.
