Insulation in Commerce, CA
Spray foam insulation in Commerce typically costs $2.75-$6.50 per square foot installed, with closed-cell foam on the higher end and open-cell on the lower. What makes Commerce different from every surrounding city is the building stock itself: a small pocket of 1940s-1960s homes ringed by millions of square feet of tilt-up concrete warehouses, cold-storage facilities, and food-processing plants. We plan every job around that reality, whether it’s dense-packing the thin wall cavities of a postwar bungalow or sealing a 30,000-square-foot warehouse roof deck where the urban heat island hits hardest. Call (424) 622-5846 and a live person answers, day or night.
Why Commerce Homes Are Different
Commerce sits far enough inland that the marine layer burns off early, and the city’s concentration of dark asphalt, concrete tilt-up roofs, and heat-generating industrial operations creates one of the most intense urban heat island effects in Los Angeles County. For the residential pockets along the city’s western and northern edges, that means small single-family homes and duplexes built in the 1940s through 1960s absorb heat all day and struggle to release it at night. Most of those homes went up with zero wall insulation and the original attic batts, which by now are compressed, dusty, and doing very little. The commercial side is even more demanding: vast metal-panel and tilt-up warehouses from the 1970s-1990s industrial boom running undersized roof insulation against commercial utility rates. Food-processing tenants along Bandini Boulevard and Washington Boulevard add another layer, since their facilities often answer to health-department or USDA standards for continuous vapor-barrier integrity. This is not a one-material-fits-all city, and we treat it that way.
Our Main Commerce Services
The two calls we take most often from Commerce homeowners are for attic insulation and crawl space encapsulation, and they usually come from the same block of postwar houses.
Attic Insulation in Commerce
Those 1940s-1960s homes along the residential edges of Commerce were built with little more than an inch or two of fiberglass in the attic, and after 60-plus years of heat and dust, most of it has settled into a thin, ineffective layer. We remove or top up what’s there, air seal the attic floor, and install new material rated for the inland heat Commerce actually gets. Every job is covered by our 90-Day Done Right Promise, and most are finished in one visit. Full details are on our Attic Insulation in Commerce page.
Crawl Space Encapsulation & Vapor Barrier in Commerce
Homes in the western residential pockets of Commerce sit close to the Los Angeles River basin, and crawl spaces here trap moisture against floor joists through the warmer months. We install heavy-duty vapor barriers up the foundation walls, seal vents and rim joists, and turn a damp, pest-friendly void into a dry, conditioned space. It’s the single best move for a Commerce home with musty odors or uneven floors. Read the full breakdown on our Crawl Space Encapsulation & Vapor Barrier in Commerce page.

Spray Foam Insulation in Commerce
Spray foam insulation in Commerce works differently than in the beach cities: our heat comes early, stays late, and radiates off acres of concrete and asphalt. On the residential side, the 1940s-1960s homes here have wall cavities and roof decks that leak air constantly, and spray foam is the only material that insulates and air seals in a single pass. On the commercial side, closed-cell foam on tilt-up warehouse roofs and cold-storage facilities is often the difference between a manageable cooling bill and a punishing one. If you’re fighting uneven temperatures in a Commerce bungalow or sweating a warehouse energy audit, Spray Foam Insulation is the first thing we’ll talk about. We spray Icynene and Demilec open- and closed-cell systems, and most jobs wrap in a single visit.
Open-Cell Spray Foam
Signs you need it
Your rooms heat up by mid-morning and the air conditioner runs constantly from June through October.
What it costs in Commerce
Open-cell spray foam in Commerce runs $2.75-$4.50 per square foot installed, depending on depth and access.
How we do it
We prep the area, spray the foam to the specified depth, and trim any excess once it cures.
Closed-Cell Spray Foam
Signs you need it
You need maximum R-value per inch, moisture resistance, or structural reinforcement in a wall or roof assembly.
What it costs in Commerce
Closed-cell spray foam in Commerce ranges $4.00-$6.50 per square foot installed, reflecting the higher material density.
How we do it
We verify the substrate is dry, spray the closed-cell foam in controlled lifts, and confirm the target thickness before leaving.
What Spray Foam Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Open-cell spray foam (attic or wall) | $2.75-$4.50 per sq ft |
| Closed-cell spray foam (roof deck or rim joist) | $4.00-$6.50 per sq ft |
| Garage ceiling or small rim joist job | $1,200-$2,800 total |
Is closed-cell spray foam worth the extra cost in Commerce?
For most Commerce homes and warehouses, yes. Closed-cell adds moisture resistance and structural rigidity, which matters on tilt-up roofs and in cold-storage applications where vapor control is non-negotiable.
Can you spray foam a Commerce warehouse roof while operations continue?
We schedule commercial spray foam in sections, usually after hours or on weekends, so tenant operations don’t stop. Call (424) 622-5846 to discuss your facility’s hours.
Blown-In Insulation in Commerce
Blown-in insulation in Commerce is the fastest, cleanest way to bring a 1940s-1960s attic or empty wall cavity up to modern thermal performance without tearing anything apart. The homes along the residential edges of Commerce have the same problem: thin wall cavities and attics that were minimally insulated when built and have only gotten worse with six decades of settling, heat, and rodent traffic. Blown-in cellulose or fiberglass fills those irregular cavities completely, something batts never could. We blow Blown-In Insulation from GreenFiber and CertainTeed, and most attic top-ups are done inside half a day.
Blown-In Cellulose
Signs you need it
Your attic insulation is thin, patchy, or compacted flat, and your upstairs rooms are consistently hotter than downstairs.
What it costs in Commerce
Blown-in cellulose in Commerce runs $1.25-$2.75 per square foot, with attic top-ups typically landing between $900 and $2,100 total.
How we do it
We air seal the attic floor, then blow cellulose to the target R-value with a calibrated machine, dense-packing wall cavities where needed.
Dense-Pack Wall Insulation
Signs you need it
Your exterior walls feel warm to the touch in summer and cold in winter, and you can hear street noise through closed windows.
What it costs in Commerce
Dense-pack wall insulation in Commerce ranges $3.00-$5.00 per square foot of wall, installed through small drill holes.
How we do it
We drill small access holes from outside or inside, dense-pack the cavity under pressure, and patch the holes to match.
What Blown-In Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic top-up with blown-in cellulose | $900-$2,100 total |
| Blown-in fiberglass attic (full) | $1,200-$2,600 total |
| Dense-pack wall insulation | $3.00-$5.00 per sq ft |
Will blown-in insulation settle in a Commerce attic?
Properly installed cellulose settles slightly and is accounted for in the install depth. We over-blow to hit the target R-value after settling, and the 90-Day Done Right Promise covers any issue in the first three months.
Can you dense-pack the walls of a 1950s Commerce home without gutting it?
Yes. We drill small access points through stucco or drywall, blow the cavity full under pressure, and repair the holes. Most jobs are completed in one day.
Radiant Barrier Installation in Commerce
Radiant barrier installation in Commerce attacks a problem most insulation never touches: radiant heat transfer from a roof that bakes under inland sun all afternoon. In a city where the urban heat island effect pushes attic temperatures past 130°F in summer, a radiant barrier reflects up to 97% of that radiant heat before it ever reaches the insulation layer below. For the 1940s-1960s homes and metal-panel warehouses across Commerce, that means a cooler attic, less strain on the HVAC, and lower cooling bills. Our crews install Radiant Barrier Installation material under roof rafters or over existing insulation, usually in a single visit.
Attic Radiant Barrier
Signs you need it
Your attic is sweltering by noon and your air conditioner runs almost continuously on hot afternoons.
What it costs in Commerce
Attic radiant barrier in Commerce runs $1.75-$3.25 per square foot installed under the roof deck.
How we do it
We staple the foil barrier to the underside of the rafters, leaving the air gap that makes the technology work.
Radiant Barrier Roof Deck
Signs you need it
You have a low-slope or metal roof and the rooms directly below are noticeably hotter than the rest of the building.
What it costs in Commerce
Radiant barrier at the roof deck in Commerce ranges $1.75-$3.25 per square foot, similar to attic installations but with different attachment methods.
How we do it
We install the barrier between the roof deck and insulation, securing it so airflow and reflectivity stay intact.
What Radiant Barrier Installation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic radiant barrier (residential) | $1.75-$3.25 per sq ft |
| Radiant barrier roof deck (commercial) | $1.75-$3.25 per sq ft |
| Radiant barrier plus ventilation upgrade | $2,200-$4,500 total |
Does a radiant barrier work in Commerce without adding traditional insulation?
A radiant barrier cuts radiant heat gain but doesn’t slow conductive heat. Pairing it with adequate attic insulation gets the best result, and our home energy audit maps exactly what your attic needs.
Can you install a radiant barrier in a Commerce metal-panel warehouse?
Yes. We attach the barrier to the underside of the roof framing with mechanical fasteners, and most warehouse sections are done in a day or two depending on square footage.
Insulation Removal & Replacement in Commerce
Insulation removal and replacement in Commerce usually starts with the same story: a 1950s attic stuffed with compacted fiberglass that rodents have been living in for decades, or a 1980s warehouse with water-damaged roof insulation no longer doing its job. In the residential pockets of Commerce, old insulation harbors dust, droppings, and heat-trapping clumps that actively work against your HVAC. On the commercial side, degraded roof insulation on tilt-up buildings drives cooling costs through the roof, literally. We remove it all, sanitize the space, and install new material sized for Commerce’s inland heat load. Our Insulation Removal & Replacement crews handle everything from small attics to full warehouse decks.
Attic Insulation Removal
Signs you need it
Your attic insulation is compressed, stained, or smells musty, and your energy bills keep climbing year over year.
What it costs in Commerce
Attic insulation removal in Commerce runs $1.50-$3.00 per square foot, including bagging and haul-away.
How we do it
We vacuum out the old material with commercial extraction equipment, then prep the attic floor for new insulation.
Contaminated Insulation Removal
Signs you need it
You’ve seen rodent droppings, nesting debris, or water staining in the attic, and the air inside the house smells stale or sour.
What it costs in Commerce
Contaminated insulation removal in Commerce ranges $2.00-$3.50 per square foot, reflecting the extra handling and sanitizing.
How we do it
We extract the contaminated material, sanitize the exposed surfaces, and apply exclusion measures before reinstalling clean insulation.
What Insulation Removal & Replacement Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic insulation removal (standard) | $1.50-$3.00 per sq ft |
| Contaminated insulation removal | $2.00-$3.50 per sq ft |
| Full removal and new blown-in insulation | $3,500-$6,500 total |
Is it cheaper to remove old insulation or just add more on top in Commerce?
Sometimes topping up works, but if the existing material is rodent-contaminated, water-damaged, or compacted hard, removal is the honest fix. We’ll tell you which path makes sense after a quick attic inspection.
Can you remove insulation from a Commerce warehouse roof without shutting down operations?
We schedule commercial removal in sections and work around your operating hours. Call (424) 622-5846 and we’ll map out a phased plan with a real person on the phone.
Attic Air Sealing in Commerce
Attic air sealing in Commerce stops the stack effect that pulls hot, dusty attic air into your living space and forces conditioned air out through every crack. The 1940s-1960s homes ringing the industrial core of Commerce were framed loose by modern standards, with unsealed top plates, open wall cavities, and can lights that leak air like open vents. In a city this hot, an unsealed attic means the AC works harder than it should from May through October. Our Attic Air Sealing program pairs foam, caulk, and blocking to close those bypasses before new insulation goes in.
Attic Floor Air Sealing
Signs you need it
Your upstairs rooms stay hot even with the AC running, and dust collects on ceiling fans and vents within days.
What it costs in Commerce
Attic floor air sealing in Commerce runs $1.00-$2.00 per square foot of attic floor, depending on how many penetrations need work.
How we do it
We seal every top plate, wire hole, and plumbing penetration with closed-cell foam and fire-rated caulk from the attic side.
Can Light & Duct Boot Sealing
Signs you need it
You can feel warm air around recessed lights in summer, or your supply registers blow weak air even after filter changes.
What it costs in Commerce
Can light and duct boot sealing in Commerce ranges $400-$900 total for a typical 1950s-era home.
How we do it
We install rated covers or seal around each fixture and boot with high-temperature caulk, then test airflow at the registers.
What Attic Air Sealing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic floor air sealing | $1.00-$2.00 per sq ft |
| Can light and duct boot sealing | $400-$900 total |
| Top plate and penetration sealing (full attic) | $600-$1,400 total |
Will attic air sealing make my Commerce home feel stuffy instead of drafty?
No. We seal uncontrolled leaks but your HVAC system still brings in fresh air as designed. The result is less dust, steadier temperatures, and lower bills, not a stale house.
How long does attic air sealing take on a Commerce bungalow?
Most single-story Commerce homes are done in four to six hours. We can usually pair it with blown-in insulation in the same visit to save you a second appointment.
Wall Insulation in Commerce
Wall insulation in Commerce fixes what the original builders never did: the 1940s-1960s homes along the residential edges of the city went up with empty wall cavities, so outside heat moves straight through the stucco and into your rooms. In a Commerce summer, that means the AC runs against an endless heat load, and in winter the walls bleed warmth right back out. We inject foam or blown-in material into those empty cavities through small holes, bringing the wall assembly up to modern thermal performance without tearing out drywall. Our Wall Insulation crews work with CertainTeed and GreenFiber materials, and most jobs wrap in one day.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls are hot to the touch in summer and cold in winter, and the house never holds temperature.
What it costs in Commerce
Injection foam wall insulation in Commerce runs $3.50-$5.50 per square foot of wall, installed through small drill holes.
How we do it
We drill through the stucco or drywall at stud intervals, inject the foam to fill the cavity, and patch the holes to match.
Interior Wall Soundproofing
Signs you need it
You can hear traffic, rail yard noise, or neighbor noise through interior walls, and bedrooms share walls with living spaces.
What it costs in Commerce
Interior wall soundproofing in Commerce ranges $3.00-$5.00 per square foot, including dense-pack material and sealing.
How we do it
We dense-pack the wall cavities with sound-absorbing insulation and seal the top plates and outlets to cut flanking noise.
What Wall Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Injection foam wall insulation | $3.50-$5.50 per sq ft |
| Drill and fill wall insulation | $3.00-$5.00 per sq ft |
| Interior wall soundproofing | $3.00-$5.00 per sq ft |
Can you insulate the walls of a 1950s Commerce stucco home without removing the stucco?
Yes. We drill from the outside through the stucco, inject the insulation, and patch the holes with color-matched material. The stucco stays intact and the walls finally do their job.
Will wall insulation alone fix my Commerce energy bills?
Wall insulation is a major piece, but attics, air leaks, and ducts all play a role too. Our home energy audit identifies exactly where your house loses energy so you spend money where it counts.
Attic Cleaning & Rodent Proofing in Commerce
Attic cleaning and rodent proofing in Commerce matters because the city’s industrial corridors support a healthy rodent population, and those rodents move into residential attics along the western and northern edges every fall. The 1940s-1960s homes here have open eaves, vent gaps, and chase penetrations that make entry easy. Once inside, rodents shred insulation, soak it with urine, and leave droppings that degrade your indoor air. We clean the space, sanitize it, seal the entry points, and install fresh insulation where needed. Our Attic Cleaning & Rodent Proofing service is the most-requested residential job in Commerce after attic insulation.
Attic Cleanout
Signs you need it
You hear scratching overhead at night, see droppings in the attic, or notice a persistent musty smell near the ceiling.
What it costs in Commerce
Attic cleanout in Commerce runs $600-$1,200 for a typical single-family home, depending on debris volume.
How we do it
We remove all contaminated materials, vacuum the space, and haul everything away for disposal.
Rodent Proofing & Exclusion
Signs you need it
You’ve had rodents return after cleaning, or you can see daylight through gaps around eaves, vents, or pipe penetrations.
What it costs in Commerce
Rodent proofing and exclusion in Commerce ranges $800-$1,600, covering entry sealing and exclusion material.
How we do it
We seal every access point with rodent-proof materials, install vent guards, and verify the attic is closed off for good.
What Attic Cleaning & Rodent Proofing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic cleanout (single-family home) | $600-$1,200 total |
| Rodent proofing and exclusion | $800-$1,600 total |
| Full cleanout, sanitizing, and insulation replacement | $2,500-$5,000 total |
Does attic cleaning and rodent proofing include new insulation in Commerce?
It can. We often combine cleanout, exclusion, and blown-in insulation replacement in a single visit, and you’ll see the bundle price before work starts.
How soon can you get to a Commerce attic with an active rodent problem?
We schedule most Commerce attic cleanouts within a few days. Call (424) 622-5846 and a live person will get you on the calendar, not a voicemail.
Home Energy Audit in Commerce
A home energy audit in Commerce answers the question every homeowner here should be asking: where is my money actually going? The 1940s-1960s homes along the residential edges of the city leak air from attics, walls, ducts, and can lights, and the inland heat load means every leak costs more here than it would nearer the coast. Our audit uses blower-door testing, thermal imaging, and duct leakage measurement to map the real heat paths through your house, then gives you a prioritized fix list. It’s the diagnostic starting point that makes every other insulation service smarter and more targeted. We run Home Energy Audit appointments in about two hours.
Blower Door Test
Signs you need it
Your heating and cooling bills feel high but you can’t tell where the house is leaking, and rooms never hold temperature.
What it costs in Commerce
A blower door test in Commerce runs $200-$400 as a standalone diagnostic, or it’s bundled with the full audit.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure exactly how much air leaks through the envelope.
Thermal Imaging Inspection
Signs you need it
You have cold spots in winter, hot spots in summer, or suspect missing insulation in walls that were never opened up.
What it costs in Commerce
Thermal imaging inspection in Commerce ranges $150-$350 as part of a full audit.
How we do it
We scan every wall, ceiling, and floor with an infrared camera to map temperature differences and locate insulation voids.
What Home Energy Audit Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Full home energy audit (blower door, thermal, duct test) | $450-$900 total |
| Standalone blower door test | $200-$400 total |
| Thermal imaging inspection | $150-$350 total |
Will a home energy audit in Commerce qualify me for rebates?
Many utility programs accept third-party audit results. We’ll give you the data and documentation you need, and you can submit it to your provider. Call (424) 622-5846 to ask what we can prepare.
How long does a home energy audit take in Commerce?
Plan on about two hours for a full audit of a single-family home. You’ll get the prioritized fix list on the spot, and most recommended work can be scheduled within the week.

What Commerce Customers Say
"The estimate had every line itemized - removal, sealing, baffles, the blown-in by the bag - and the final invoice matched it exactly. Two other companies quoted a single number and could not tell me what R-value they were installing."
- Priya Raman"Crawl space smelled musty and the floors were cold. Full encapsulation with the thick liner taped at every seam, and a dehumidifier sized for the space. The hygrometer they left reads 48 percent now instead of the 70s."
- Elena Vasquez"Injection foam in the walls of our 1950s house - no drywall demolition, just small holes patched and painted the same day. The street noise in the front bedroom is half what it was."
