Insulation in Compton, CA
Crawl space encapsulation and vapor barrier work in Compton typically runs $2,800-$5,500 for a standard 900-1,200 square foot post-WWII bungalow, with most jobs completed in two days. Because Compton is designated a Disadvantaged Community under California’s CalEnviroScreen framework, many homeowners qualify for free or deeply subsidized insulation upgrades through Weatherization Assistance Programs and TECH Clean California incentives that neighboring cities don’t access at the same scale. We’re Envelope Insulation Co., and our Compton jobs always begin with a written price and a blower-door test so you can see exactly what your home is losing before we start.

Why Compton Homes Are Different
Compton’s housing stock is almost entirely small post-WWII wood-frame stucco bungalows built between 1945 and 1970, most between 900 and 1,200 square feet. The original fiberglass batts in these attics have compacted to near-zero R-value after 60-plus years, and unpermitted garage-to-living-space conversions are common - built with zero wall or ceiling insulation and often sharing an open attic plane with the main house.
The local climate creates genuine cooling-load pressure. The Pacific marine layer burns off by mid-morning, and the surrounding industrial corridor - the Alameda Corridor freight rail, the 710 Freeway, and nearby refineries in Carson and Wilmington - produces a measurable urban heat island. Summer afternoons in Compton run well above coastal Long Beach, making attic radiant barrier and high-R insulation a real utility-bill issue, not a code checkbox. Our crews also navigate DAC-specific grant paperwork that wealthier cities simply don’t generate at this volume.
Our Main Compton Services
Most Compton homeowners who call us start with attic work or spray foam, but blown-in remains popular for its speed and cost on compact floor plans.
Attic Insulation in Compton
Attic insulation in Compton usually means removing compacted 1950s fiberglass and bringing the space up to Title 24’s R-38 minimum, which these 900-1,200 square foot bungalows almost never meet. We often find unpermitted additions sharing the attic plane with zero insulation at the roofline. Every attic job includes air sealing first, then insulation, with before-and-after blower-door numbers published so you can verify the result. Attic Insulation in Compton details our full process and pricing.
Spray Foam Insulation in Compton
Spray foam insulation in Compton works best for unpermitted garage conversions and room additions that have no existing wall or ceiling insulation to upgrade. Closed-cell foam at 2-3 inches delivers R-14 to R-21 and acts as its own air barrier, which matters in spaces that were never properly sealed to begin with. We source from Owens Corning and Demilec, and every job gets a written price before work starts. Spray Foam Insulation in Compton covers applications and typical costs.
Blown-In Insulation in Compton
Blown-in insulation in Compton is the fastest path to code compliance on straightforward attics with intact existing structure and no major contamination. We blow fiberglass or cellulose over a fully sealed attic floor, never over unsealed penetrations. For qualifying DAC households, this upgrade is often fully subsidized through Weatherization Assistance. Blown-In Insulation in Compton explains material options and grant navigation.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Compton
Compton’s 1940s-1960s bungalows were built with vented crawl spaces that pull moisture from the clay-heavy soil during winter rains and release it into the floor system year-round. Many of these homes have never had a vapor barrier installed, and the resulting wood rot, mold, and musty indoor air is what finally drives the call. Crawl Space Encapsulation & Vapor Barrier is our primary service in Compton because the housing stock and soil conditions make it one of the highest-impact upgrades available, often subsidized for DAC-qualified owners.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has bare dirt, standing water after rain, or a persistent musty smell rising through the floor.
What it costs in Compton
Most vapor barrier installations in Compton run $1,200-$2,400 for a standard bungalow crawl space.
How we do it
We lay 6-mil minimum polyethylene sheeting, seam-seal all overlaps, and mechanically fasten to foundation walls before sealing penetrations.
Crawl Space Encapsulation
Signs you need it
You’re seeing floor joist mold, insulation falling from the subfloor, or warped hardwood that worsens seasonally.
What it costs in Compton
Full encapsulation in Compton typically ranges from $3,500-$7,000 depending on crawl height and conditioning requirements.
How we do it
We install a reinforced vapor barrier across floor and walls, seal all vents and penetrations, and add mechanical dehumidification where moisture load demands it.
What Crawl Space Encapsulation & Vapor Barrier Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Vapor barrier (6-mil, dirt floor) | $1,200 - $2,400 |
| Partial encapsulation (walls + floor) | $2,800 - $4,500 |
| Full encapsulation with dehumidifier | $3,500 - $7,000 |
Is crawl space work covered by Compton DAC grants?
Yes - CalEnviroScreen Disadvantaged Community status makes Compton homes eligible for Weatherization Assistance Program coverage of vapor barriers, encapsulation, and related moisture control, often at zero out-of-pocket cost. Call (628) 226-1097 and we’ll walk you through the qualification check.
How long does crawl space encapsulation take?
Most Compton crawl spaces are completed in one to two days; larger or conditioned encapsulations may run three days. We deliver a written scope and warranty before anyone enters the space, per Haven Standard Clause 1.
Radiant Barrier Installation in Compton
Compton’s urban heat island pushes attic temperatures well above what coastal LA experiences, and the uninsulated or under-insulated attics common in 1950s bungalows turn that roof heat into real cooling load. Radiant barrier installation reflects infrared radiation before it radiates into the living space, dropping attic surface temperatures by 20-40 degrees on peak summer afternoons. Radiant Barrier Installation is particularly effective here because the climate penalty is steep and the existing insulation is usually inadequate.
Attic Radiant Barrier
Signs you need it
Your AC runs continuously after 2 p.m. in summer, the attic floor is too hot to touch, and cooling bills spike June through September.
What it costs in Compton
Attic radiant barrier installation in Compton typically runs $1,500-$3,200 for a standard bungalow.
How we do it
We staple perforated foil across rafter bottoms or lay it over existing attic insulation, ensuring ventilation paths remain open per code.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing or have the decking exposed, and you want the most effective radiant barrier configuration available.
What it costs in Compton
Roof-deck radiant barrier application during re-roofing in Compton runs $2,000-$4,500 depending on roof complexity.
How we do it
We apply foil-faced sheathing or liquid-applied radiant coating directly to the roof deck before new roofing is installed.
What Radiant Barrier Installation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Attic radiant barrier (foil, existing attic) | $1,500 - $3,200 |
| Radiant barrier roof deck (during re-roof) | $2,000 - $4,500 |
| Radiant barrier with attic air sealing package | $2,800 - $5,500 |
Does radiant barrier work without more insulation?
It helps, but we don’t install radiant barrier without first air-sealing the attic floor and assessing whether the existing insulation can reach R-38; the barrier reflects heat, but conduction through inadequate insulation still costs you.
Can DAC grants cover radiant barrier in Compton?
Weatherization Assistance in DAC areas often covers radiant barrier when bundled with insulation upgrades; standalone radiant barrier is less commonly funded, but we’ll verify your specific eligibility during the free estimate.
Insulation Removal & Replacement in Compton
Compton’s 60-plus-year-old bungalows contain fiberglass batts that have settled, compacted, and often been compromised by roof leaks, rodent activity, or unpermitted work above. Removing this material is not optional when it’s contaminated or compressed below R-11; blowing new insulation over it traps moisture and hides problems. Insulation Removal & Replacement in Compton typically reveals unpermitted additions, open attic planes, and penetrations that were never sealed.
Attic Insulation Removal
Signs you need it
Your attic insulation is flat, discolored, or has visible rodent droppings and compressed paths through the material.
What it costs in Compton
Attic insulation removal in Compton runs $1.00-$2.50 per square foot, or $900-$3,000 for a typical bungalow.
How we do it
We use HEPA-filtered vacuums and negative air machines to remove all material, then bag and dispose per California waste regulations.
Contaminated Insulation Removal
Signs you need it
You smell urine or mildew when the HVAC runs, or you’ve had roof leaks that saturated the insulation before repair.
What it costs in Compton
Contaminated removal with sanitizing in Compton typically ranges from $2,000-$5,000 depending on contamination extent.
How we do it
We remove all compromised material, apply EPA-registered antimicrobial to the deck and joists, and document with photos before installing new insulation.
What Insulation Removal & Replacement Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Standard attic insulation removal | $900 - $3,000 |
| Contaminated removal + sanitizing | $2,000 - $5,000 |
| Removal + replacement with new R-38 | $3,500 - $7,500 |
Do I have to leave during insulation removal?
No, but we seal the work zone from your living space with plastic barriers and run negative air machines; most homeowners stay elsewhere for the day if they have respiratory sensitivities.
How do I know if my old insulation is hazardous?
We test suspect material on site; vermiculite and pre-1990 fiberglass with formaldehyde binders require special handling, and we’ll show you the lab results before proceeding.
Attic Air Sealing in Compton
Every Compton bungalow we’ve entered has leaky top plates, unsealed can lights, and duct boots pulling conditioned air into the attic; the 1940s-1960s construction predates modern air-barrier requirements entirely. Air sealing must happen before any insulation goes in, because blowing material over leaks simply hides them and can trap moisture against the drywall. Attic Air Sealing is the foundation of every job we do in Compton, and we publish before-and-after blower-door numbers so you can verify the result.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at outlet plates on exterior walls, or your blower-door test shows excessive leakage at the ceiling plane.
What it costs in Compton
Top plate and penetration sealing in Compton typically runs $800-$2,000 for a standard bungalow.
How we do it
We foam-seal all top plate gaps, wire penetrations, and plumbing stacks, then verify with blower-door directed air leakage testing.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights flicker in wind, or you see dusty air streaks around ceiling registers when the HVAC runs.
What it costs in Compton
Can light and duct boot sealing in Compton ranges from $400-$1,200 depending on fixture count and accessibility.
How we do it
We install fire-rated covers over can lights, seal duct boots with mastic and mesh, and pressure-test the HVAC system for remaining leakage.
What Attic Air Sealing Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Top plate & penetration sealing | $800 - $2,000 |
| Can light & duct boot sealing | $400 - $1,200 |
| Full attic air sealing package | $1,500 - $3,500 |
Can air sealing alone lower my bill?
Yes - we’ve seen 15-30 percent cooling load reduction in Compton bungalows from air sealing alone, before any insulation is added; the blower-door number tells the story.
Is air sealing required before adding insulation?
We won’t blow insulation over an unsealed attic floor; it’s not an upsell, it’s the order the work has to happen in, and it’s why we publish blower-door results on every job.
Wall Insulation in Compton
Compton’s unpermitted garage conversions and rear additions were built with 2×4 studs, no insulation, and often no proper air barrier to the exterior stucco. The original 1950s walls have empty stud bays or degraded batts that settled decades ago. Wall Insulation in Compton means drilling and filling from the exterior, or dense-packing from the interior when siding replacement isn’t planned.
Drill & Fill Wall Insulation
Signs you need it
Your exterior walls are cold to the touch in winter, or you have uninsulated additions that were never brought up to code.
What it costs in Compton
Drill and fill wall insulation in Compton runs $2.00-$4.50 per square foot of wall area, or $2,500-$6,000 for a typical bungalow.
How we do it
We drill 2-inch holes through stucco or siding at stud-bay spacing, blow dense-pack cellulose to 3.5 pounds per cubic foot, then patch and match finish.
Injection Foam Wall Insulation
Signs you need it
You need air sealing and insulation together in a single step, or the wall cavities have irregular obstructions that loose fill won’t navigate.
What it costs in Compton
Injection foam wall insulation in Compton typically ranges from $3.50-$6.50 per square foot of wall area.
How we do it
We inject slow-rise open-cell foam through controlled ports, filling the cavity completely and creating an air barrier as the material expands and cures.
What Wall Insulation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Drill & fill (cellulose, stucco exterior) | $2,500 - $6,000 |
| Injection foam (open-cell) | $3,500 - $8,000 |
| Garage conversion wall package | $1,800 - $4,500 |
Will drill and fill damage my stucco?
We match the patch to your existing texture and color; on smooth stucco the repair is nearly invisible, and on heavy lace we blend the patch into the surrounding pattern.
Can DAC grants cover wall insulation?
Weatherization Assistance often covers wall insulation for DAC-qualified Compton homes when the existing walls are empty or below code; we handle the grant paperwork as part of our estimate process.
Attic Cleaning & Rodent Proofing in Compton
Compton’s mature neighborhoods with established tree canopy and proximity to industrial corridors produce steady rodent pressure on rooflines and soffits. Once squirrels or rats access the attic, they compress insulation, contaminate it with urine and droppings, and create entry points for more pests. Attic Cleaning & Rodent Proofing in Compton always includes exclusion work, because cleaning without sealing the entries is temporary.
Attic Cleanout & Sanitizing
Signs you need it
You hear scratching at dawn or dusk, find droppings in the attic, or smell ammonia when the HVAC pulls attic air.
What it costs in Compton
Attic cleanout and sanitizing in Compton typically runs $1,500-$4,000 depending on contamination level and attic size.
How we do it
We remove all contaminated material, HEPA-vacuum the deck, apply antimicrobial treatment, and document the space with photos before any restoration work.
Rodent Proofing & Exclusion
Signs you need it
You’ve had repeated pest control visits but the rodents return, or you can see gaps at eaves, vents, or where utilities penetrate the roofline.
What it costs in Compton
Rodent proofing and exclusion in Compton ranges from $800-$2,500 for a standard bungalow with accessible eaves and soffits.
How we do it
We seal all entry points with rodent-proof materials, install hardware cloth over vents, and guarantee the exclusion for one year with our 365-Day Done Right Promise.
What Attic Cleaning & Rodent Proofing Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Attic cleanout & sanitizing | $1,500 - $4,000 |
| Rodent proofing & exclusion | $800 - $2,500 |
| Full attic restoration (cleanout + proofing + insulation) | $4,000 - $9,000 |
How do I know if rodents are in my attic?
Listen for scratching at dawn and dusk, check for droppings near attic hatches, and look for compressed insulation trails; we confirm with a camera inspection during our free estimate.
Will insurance cover rodent-damaged insulation?
Most homeowner policies exclude rodent damage, but we provide a documented photo record and written scope that helps if you’re appealing; some DAC programs cover contaminated removal regardless of insurance.
Home Energy Audit in Compton
A home energy audit in Compton reveals what 70-year-old construction hides: unsealed top plates, empty wall cavities, unpermitted additions bleeding conditioned air into the attic, and insulation compressed below functional R-value. The audit is the map for every other service, and for DAC-qualified homeowners, it’s often the gateway to fully subsidized upgrades. Home Energy Audit is where we start when a Compton homeowner wants to see numbers before deciding.
Blower Door Test
Signs you need it
Your home feels drafty despite closed windows, or your energy bills are high and you don’t know where the air is leaving.
What it costs in Compton
A standalone blower-door test in Compton runs $300-$600; it’s included free when you proceed with recommended work.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 to quantify total envelope leakage.
Thermal Imaging Inspection
Signs you need it
You have cold spots on exterior walls, suspect missing insulation, or need documentation for a DAC grant application.
What it costs in Compton
Thermal imaging inspection in Compton ranges from $250-$500 as a standalone service, or bundled with the full audit.
How we do it
We scan the building envelope with an infrared camera during heating or cooling season, identifying insulation gaps, air leakage, and moisture patterns that visual inspection misses.
What Home Energy Audit Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Blower-door test (standalone) | $300 - $600 |
| Thermal imaging inspection | $250 - $500 |
| Full home energy audit | $400 - $800 |
Is the energy audit free if I do the work?
Yes - we credit the audit fee against any work we perform, and for DAC-qualified Compton homes the audit itself is often covered by Weatherization Assistance.
What does the audit report include?
You receive thermal images, blower-door readings, a prioritized scope with written prices for each recommendation, and the documentation needed for grant applications.
