Insulation in Compton, CA
Crawl space encapsulation and vapor barrier installation in Compton typically runs $3,200-$6,800 for the area’s compact post-war tract homes, with most jobs completed in two days. The city’s 1940s-1960s housing stock sits on raised foundations with vented crawl spaces that pull in moisture from Compton’s clay-heavy soil, making ground-sealing work one of the highest-impact envelope upgrades for both tenant comfort and long-term structural health. Call (424) 704-9866 for a written price before any work starts.
Why Compton Homes Are Different
Compton’s built environment is defined by density and deferred maintenance. The city is packed with small post-WWII stucco-over-wood-frame homes, mostly 800-1,200 square feet, built between 1945 and 1970 with low-pitched roofs and attic cavities that were originally insulated with thin fiberglass batts or early blown wool. That material has compressed to negligible R-values over 50-70 years, and because a significant share of these properties transitioned to long-term rental stock 30-50 years ago, many attics and wall cavities have never been touched.
Compton sits 12-15 miles inland, far enough from the marine layer to lose coastal cooling by midday. Summer highs push into the low-to-mid 90s°F, and those shallow attics trap heat aggressively, routinely exceeding 130°F. For SCE customers on tiered or time-of-use rates, attic performance isn’t abstract; it’s the difference between manageable bills and summer sticker shock.
There’s another factor: pre-1978 homes here may contain original loose-fill or batt insulation with asbestos. We test before disturbing anything. Abatement requirements add cost and time that must be disclosed upfront, especially on investor-owned properties where owners manage remotely and may be unfamiliar with California asbestos rules.
Our Main Compton Services
Most calls from Compton homeowners center on attic performance and whole-home envelope upgrades. Here are the three services we route to dedicated Compton pages:
Attic Insulation in Compton
Attic insulation in Compton means retrofitting shallow cavities in 1940s-1960s tract homes where original batts have compressed to dust or never existed. We air-seal first, then insulate, and publish before-and-after blower-door numbers so you can verify the result. Attic Insulation in Compton covers our full process, material options from Knauf and Johns Manville, and what shallow-attic jobs cost in this market.

Spray Foam Insulation in Compton
Spray foam works well in Compton’s uninsulated wall cavities and tight attic spaces where batts won’t perform. We use open-cell and closed-cell products from approved manufacturers, applied after air sealing is complete. Spray Foam Insulation in Compton breaks down when foam makes sense versus blown-in, and what it costs for a typical 1,000-square-foot home here.

Blown-In Insulation in Compton
Blown-in cellulose or fiberglass is the most common attic retrofit for Compton’s post-war stock, filling irregular cavities and covering top plates that batts miss. We blow only after sealing all penetrations. Blown-In Insulation in Compton details density requirements, blower-door-verified results, and pricing for the area’s compact footprints.

Crawl Space Encapsulation & Vapor Barrier in Compton

Compton’s 1940s-1960s tract homes sit on raised perimeter foundations with vented crawl spaces that were built to codes predating modern moisture control. The clay-heavy soils in this part of the Los Angeles Basin wick groundwater upward, and those vents pull humid air in year-round. In summer, that moisture meets the cooled floor above and condenses; in winter, it drives mold and wood rot. Crawl Space Encapsulation & Vapor Barrier is the systematic fix: ground cover, sealed walls, and conditioned air.
Crawl Space Vapor Barrier
Signs you need it
Musty odors rising through floor registers, sagging fiberglass batts hanging from joists, or visible efflorescence on foundation walls mean ground moisture is migrating upward unchecked.
What it costs in Compton
A 6-mil or thicker polyethylene ground cover for a typical Compton crawl space runs $1,800-$3,200, with most homes in the 800-1,200 square foot range landing near the middle.
How we do it
We remove debris and old fallen insulation, grade the soil surface, lay overlapping polyethylene sheets sealed at seams and walls, and secure perimeters to foundation walls with mechanical fasteners.
Crawl Space Encapsulation
Signs you need it
Chronic humidity above 70 percent, mold on joists or subfloor, or warped hardwood flooring above the crawl space indicate the entire cavity needs sealing, not just ground cover.
What it costs in Compton
Full encapsulation with closed-cell foam on walls, sealed vents, and mechanical dehumidification for a Compton-sized crawl space typically ranges $4,500-$7,800.
How we do it
We seal all vents, apply closed-cell foam to foundation walls, install a sealed vapor barrier across the ground and up walls, then add a condensate-pumped dehumidifier sized to the cavity volume.
What Crawl Space Encapsulation & Vapor Barrier Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Vapor barrier (ground cover only) | $1,800 - $3,200 |
| Partial encapsulation (walls + ground) | $3,200 - $5,500 |
| Full encapsulation with dehumidifier | $4,500 - $7,800 |
How long does crawl space encapsulation take in Compton?
Most Compton jobs finish in 1-2 days. Full encapsulation with dehumidifier installation may extend to 3 days if electrical work is needed. We provide a written schedule with the price.
Will encapsulation lower my SCE bill?
Yes, typically 10-20 percent in Compton’s post-war stock. Sealed crawl spaces reduce the load on ducts running through the cavity and cut moisture-driven heat transfer through the floor. Call (424) 704-9866 for a free estimate with projected savings.
Radiant Barrier Installation in Compton

Compton’s shallow, low-pitched attics are solar ovens from May through October. Roof decking sits close to the ceiling plane, and without a radiant barrier, that 130°F+ roof surface radiates heat directly into the living space below. A radiant barrier, typically aluminum-foil-faced sheathing or draped foil, blocks 90-97 percent of that radiant heat transfer. Radiant Barrier Installation pairs especially well with air sealing and insulation upgrades in Compton’s climate.
Attic Radiant Barrier
Signs you need it
Second rooms that stay 10-15 degrees hotter than the rest of the house, air conditioning that runs continuously after 2 p.m., or ceiling surfaces that feel warm to the touch in summer.
What it costs in Compton
Draped foil radiant barrier installed across attic rafters in a typical Compton home runs $1,200-$2,400, depending on attic complexity and access.
How we do it
We staple perforated aluminum foil across the underside of roof rafters, maintaining a ¾-inch air gap above and ensuring ventilation paths stay open at soffits and ridges.
Radiant Barrier Roof Deck
Signs you need it
During re-roofing or major attic work, upgrading to radiant-barrier sheathing addresses the problem at the source rather than adding a retrofit layer below.
What it costs in Compton
Radiant-barrier OSB roof deck replacement during roofing work adds $1.50-$2.80 per square foot of roof area to standard sheathing costs.
How we do it
We coordinate with your roofing contractor or our own crew to install foil-faced OSB during tear-off, taping seams and maintaining proper deck ventilation per manufacturer specs.
What Radiant Barrier Installation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Draped foil (retrofit) | $1,200 - $2,400 |
| Radiant-barrier roof deck (during re-roof) | $1.50 - $2.80/sq ft |
| Radiant barrier + attic air sealing package | $2,800 - $4,500 |
Does radiant barrier work without insulation?
It helps, but not enough. Radiant barriers block radiant heat; they don’t stop conductive heat flow through the ceiling. We always pair barrier installation with proper attic insulation and air sealing for measured results.
How much cooler will my attic get?
Attic air temperature drops 20-35°F with a properly installed radiant barrier in Compton’s sun exposure. The ceiling below runs cooler, and AC runtime typically falls 15-25 percent. Call (424) 704-9866 for a blower-door-tested package quote.
Insulation Removal & Replacement in Compton

Compton’s rental-heavy housing stock means many attics contain 50-70 years of layered, degraded, or contaminated insulation. We’ve removed everything from original rock wool compressed to R-3, to rodent-compromised batts, to vermiculite that tested positive for asbestos. Insulation Removal & Replacement starts with testing, includes safe disposal, and ends with new material installed to current code.
Contaminated Insulation Removal
Signs you need it
Visible rodent droppings, urine staining, mold growth, or a persistent organic odor in the attic means the existing insulation is a health hazard, not just inefficient.
What it costs in Compton
Contaminated insulation removal with HEPA containment, PPE protocols, and disposal for a typical Compton attic runs $2,800-$4,800 before replacement.
How we do it
We erect containment, run negative air machines, remove material with industrial vacuums into sealed bags, then apply antimicrobial treatment to exposed surfaces before installing new insulation.
Vermiculite & Old Insulation Removal
Signs you need it
Gray, pebbly granules between joists, or any loose-fill insulation installed before 1990, requires asbestos testing before disturbance per California regulations.
What it costs in Compton
Vermiculite removal with abatement protocols, if asbestos is present, ranges $5,500-$9,500 for a Compton-sized attic; negative tests allow standard removal at $1,800-$3,200.
How we do it
We collect a sample for EPA-certified lab analysis, then proceed under abatement protocols or standard removal based on results, with all documentation provided to the homeowner.
What Insulation Removal & Replacement Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Standard insulation removal (no contamination) | $1,800 - $3,200 |
| Contaminated removal + sanitizing | $2,800 - $4,800 |
| Vermiculite removal with abatement | $5,500 - $9,500 |
Do I have to leave during removal?
For standard removal, no. For asbestos abatement, yes, typically 24-48 hours until clearance sampling passes. We coordinate timing and provide written clearance documentation.
Can you remove insulation without replacing it?
We can, but we don’t recommend it. An uninsulated attic in Compton’s climate creates immediate comfort and cost problems. Our written scope includes replacement options with exact pricing.
Attic Air Sealing in Compton

Compton’s post-war tract homes were built with top plates, wire penetrations, and can-light cutouts that leak conditioned air continuously. A blower-door test on an unsealed Compton attic typically reads 3,500-5,000 CFM50, meaning the house replaces its entire air volume every 20-30 minutes under mild pressure. Attic Air Sealing is the first step in every attic job we do; we won’t blow insulation over a leaky floor.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling fixtures, cobwebs concentrated at wall-ceiling joints, or rooms that never reach set temperature despite new insulation all signal top-plate leakage.
What it costs in Compton
Comprehensive top-plate and penetration sealing for a typical Compton attic runs $1,400-$2,600, including blower-door verification.
How we do it
We access top plates by moving existing insulation, seal all joints with acoustic sealant and rigid foam, foam or caulk every wire and pipe penetration, then retest with the blower door.
Can Light & Duct Boot Sealing
Signs you need it
Hot attic air dumping through recessed lights in summer, or visible gaps where flex duct meets drywall, mean conditioned air is escaping directly to the attic.
What it costs in Compton
Sealing can lights with approved covers and mastic-sealing duct boots adds $800-$1,800 to a standard air-sealing job in Compton’s compact attics.
How we do it
We install fire-rated airtight covers over IC and non-IC cans, seal with firestop caulk, then apply mastic (never tape alone) to all duct connections and boots.
What Attic Air Sealing Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Basic attic air sealing (top plates, penetrations) | $1,400 - $2,600 |
| Air sealing + can light covers | $2,200 - $3,800 |
| Full package with duct sealing | $2,800 - $4,500 |
Will air sealing alone save money?
Yes, typically 15-25 percent on heating and cooling in Compton’s stock. But the real value is enabling insulation to perform. Blown fiberglass over a leaky attic floor is largely wasted.
How do I know it worked?
We provide before-and-after blower-door numbers on every job. A typical Compton home drops from 4,200 to 2,100 CFM50 after proper sealing. You get the readings in writing.
Wall Insulation in Compton

Compton’s 1940s-1960s tract homes were built with empty stud cavities or, at best, thin rock-wool batts that have settled to the bottom. Because many have been rentals for decades, walls were never upgraded. Wall Insulation in these homes means drilling access holes and injecting material, a retrofit specialty that requires knowing where plumbing and wiring run in post-war framing.
Drill & Fill Wall Insulation
Signs you need it
Exterior walls that are hot to the touch in summer, cold in winter, or rooms with two exterior walls that are unusable in temperature extremes indicate empty cavities.
What it costs in Compton
Drill-and-fill with dense-pack cellulose for a typical Compton home’s exterior walls runs $3,500-$6,500, depending on total wall area and interior finish type.
How we do it
We drill 2-inch holes at stud-bay spacing, either from exterior or interior, blow cellulose to 3.5 pounds per cubic foot density, then patch and match texture.
Injection Foam Wall Insulation
Signs you need it
Homes with existing batt insulation that has compressed or degraded, but where removal isn’t practical, benefit from slow-rise injection foam that fills voids without tear-out.
What it costs in Compton
Injection foam for partial-fill or retrofit applications in Compton’s small homes ranges $4,200-$7,800, with open-cell options at the lower end and closed-cell at the upper.
How we do it
We access cavities through minimal openings, inject slow-rise foam that expands to fill irregular spaces, then seal access points; we verify fill with thermal imaging.
What Wall Insulation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Dense-pack cellulose (drill & fill) | $3,500 - $6,500 |
| Open-cell injection foam | $4,200 - $6,200 |
| Closed-cell injection foam | $5,800 - $7,800 |
Will drilling damage my walls?
Exterior access leaves small holes that we match to stucco or siding. Interior access requires drywall patching and texture matching. We specify the approach and finish in the written scope.
How much does wall insulation help in Compton?
Empty walls in Compton’s climate are like having windows without glass. Filling them typically reduces conductive heat gain by 40-60 percent and eliminates the “hot wall” effect that makes west-facing rooms unusable. Call (424) 704-9866 for a thermal imaging assessment.
Attic Cleaning & Rodent Proofing in Compton

Compton’s mature neighborhoods with established tree canopy and older rooflines see steady rodent pressure. Roof rats and mice access attics through eave gaps, vent screens, and plumbing penetrations, then nest in degraded insulation. Attic Cleaning & Rodent Proofing removes contamination, sanitizes the space, and seals entry points so the problem stays solved.
Attic Sanitizing & Decontamination
Signs you need it
Visible droppings, urine-stained insulation, or a sharp ammonia odor in the attic indicate active or recent rodent occupation requiring professional decontamination.
What it costs in Compton
Attic sanitizing with HEPA vacuuming, enzyme treatment, and antimicrobial application for a typical Compton attic runs $1,800-$3,400.
How we do it
We remove contaminated material, HEPA-vacuum all surfaces, apply enzyme neutralizer to break down organic waste, then fog with antimicrobial before any new work begins.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds at night, gnawed wires, or repeated trapping success without sealing entry points means you’re managing symptoms, not solving the problem.
What it costs in Compton
Comprehensive rodent exclusion with steel mesh, concrete patch, and vent screening for a Compton home typically ranges $1,400-$2,800.
How we do it
We inspect roofline, eaves, soffits, vents, and foundation with photo documentation, seal all entry points ¼-inch or larger with rodent-proof materials, and provide the photo record.
What Attic Cleaning & Rodent Proofing Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Attic sanitizing & decontamination | $1,800 - $3,400 |
| Rodent proofing & exclusion | $1,400 - $2,800 |
| Full package (cleaning + proofing + re-insulation) | $4,200 - $7,200 |
Do you trap rodents or just seal?
We coordinate with licensed pest control for active infestations, then perform exclusion to prevent re-entry. Our scope is structural sealing; we don’t apply poisons or bait.
How do I know they won’t get back in?
We provide a Documented Photo Record of every sealed entry point and a written 365-Day Done Right Promise on exclusion work. If rodents re-enter through our work, we return and fix it.
Home Energy Audit in Compton

A home energy audit in Compton reveals what decades of deferred maintenance and zero-original-insulation construction have accumulated. Our audit combines blower-door testing, thermal imaging, and combustion safety checks to produce a prioritized scope with exact pricing for each measure. Home Energy Audit is where every Compton job should start if the homeowner doesn’t know what the attic, walls, and ducts actually look like.
Blower Door Test
Signs you need it
High utility bills with no obvious cause, rooms that vary by more than 5 degrees, or a house that feels drafty despite closed windows all indicate excessive air leakage.
What it costs in Compton
A standalone blower-door test with written report for a Compton home runs $350-$550; it’s credited toward any work we perform.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure CFM50 leakage, then use smoke pencils and thermal imaging to locate dominant leak paths.
Thermal Imaging Inspection
Signs you need it
Invisible insulation gaps, moisture intrusion behind walls, or duct leaks in inaccessible chases all show as temperature anomalies that thermal cameras reveal instantly.
What it costs in Compton
Thermal imaging as part of a full audit adds $200-$350; it’s included in our comprehensive audit package at $550-$850.
How we do it
We scan all exterior walls, ceilings, and accessible ductwork with a FLIR camera during blower-door depressurization, then mark anomalies on floor plans in the written report.
What Home Energy Audit Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Blower-door test with written report | $350 - $550 |
| Full audit (blower door + thermal + insulation inspection) | $550 - $850 |
| Audit with duct leakage testing | $750 - $1,100 |
Is an audit worth it if I already know I need insulation?
Yes. We’ve found $2,000+ in unnecessary proposed work on competing quotes, and identified air-sealing priorities that change the insulation scope entirely. The audit pays for itself in scope clarity.
What do I get after the audit?
A written report with blower-door number, thermal images, prioritized measures with exact pricing, and a photo record of conditions found. No work starts until you approve a written scope.
