Insulation in Commerce, CA
Spray foam insulation in Commerce works differently than in almost any neighboring city. With roughly 12,000 residents but millions of square feet of warehouses, distribution centers, and tilt-up concrete buildings, Commerce jobs skew heavily toward large flat-roof assemblies and metal building envelopes. The dark rooftops and asphalt truck yards create a genuine urban heat island that pushes interior temperatures far above the LA Basin baseline, making high-R roof insulation a direct operating cost issue. Call (626) 606-2964 to talk specifics about your building.
Why Commerce Homes Are Different
Commerce is one of the most heavily industrialized cities in the LA Basin. The dominant building stock is mid-20th-century tilt-up concrete and metal-frame industrial structures with flat built-up roofs, not the residential retrofits you see across the line in Bell Gardens or Montebello. Inside those older commercial envelopes, degraded or absent roof-deck insulation is usually the biggest energy liability. The small residential pockets are mostly modest 1940s to 1960s wood-frame homes, many still running original batt insulation or none at all in the walls. Compounding everything, the density of dark rooftops and minimal tree canopy makes Commerce measurably hotter than surrounding residential cities, so cooling loads stay high from June through October. On older industrial facilities built between the 1950s and 1970s, spray-applied or loose-fill insulation on roof decks and around mechanical systems may contain asbestos, so upgrade bids routinely start with an asbestos survey and abatement coordination before new material can go in.
Our Main Commerce Services
Two services dominate the calls we get from Commerce property owners, one for the residential pockets and one for buildings on slab foundations.
Attic Insulation in Commerce
For the 1940s to 1960s wood-frame homes in Commerce’s residential areas, attic insulation is usually the highest-ROI upgrade available. Many of these homes still have original batt insulation compressed under decades of heat, and the urban heat island means attic temperatures here run hotter than in greener cities, forcing aging AC systems to work harder. Attic Insulation in Commerce covers what we find in these attics and how we fix it.

Crawl Space Encapsulation & Vapor Barrier in Commerce
Homes in Commerce with raised foundations sit close to the water table and the industrial-grade heat of the surrounding basin, which makes crawl spaces trap moisture and send humid air up through the floors. Encapsulation stops that cycle and keeps HVAC from pulling damp, dusty air into the living space. Crawl Space Encapsulation & Vapor Barrier in Commerce explains what the full job involves here.

Spray Foam Insulation in Commerce
Spray foam insulation in Commerce is the workhorse fix for metal building envelopes, flat built-up roofs, and older tilt-up structures that leak conditioned air through thousands of small penetrations. Where Commerce’s warehouse rooftops bake in the heat island, closed-cell foam on the roof deck adds R-value and an air seal in one pass, cutting cooling load in a way batt or loose-fill cannot match. We install spray foam insulation in both residential attics and commercial assemblies, using open-cell for interior cavities and closed-cell where moisture or structural strength matters.
Open-Cell Spray Foam
Signs you need it
Your attic gets punishingly hot in summer and your upstairs rooms stay 10 to 15 degrees warmer than the rest of the building.
What it costs in Commerce
Open-cell spray foam in Commerce typically runs $1.20 to $2.20 per board foot installed at typical depths.
How we do it
We prep the cavity by clearing debris and verifying wiring, then spray the foam to the specified depth and trim any over-expansion after it cures.
Closed-Cell Spray Foam
Signs you need it
You have a flat roof deck with degraded insulation, or a metal building where interior condensation forms on the walls and roof purlins.
What it costs in Commerce
Closed-cell foam in Commerce typically lands between $2.00 and $3.50 per board foot installed, depending on depth and access.
How we do it
We spray directly onto the roof deck or wall surface in lifts, building thickness gradually so the foam bonds fully and forms a continuous air and vapor barrier.
What Spray Foam Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Open-cell spray foam (installed, per board foot) | $1.20 - $2.20 |
| Closed-cell spray foam (installed, per board foot) | $2.00 - $3.50 |
| Full attic spray foam retrofit (small residential attic) | $600 - $3,000 |
Can spray foam reduce cooling costs in Commerce?
Yes, often by a noticeable margin because the air seal stops conditioned air from escaping through the roof deck. In Commerce’s heat island, that seal matters more than the R-value alone. Call (626) 606-2964 for a building-specific estimate.
Is spray foam safe in older Commerce buildings?
We check for asbestos-containing insulation on pre-1980 roof decks and mechanical areas before any spray foam work begins. If abatement is needed, we coordinate it before installation, never around it.
Blown-In Insulation in Commerce
Blown-in insulation in Commerce is the practical answer for the 1940s to 1960s wood-frame homes whose attics still carry thin, settled original batt. The attic heat from Commerce’s dense industrial surroundings pushes down into living spaces, and loose-fill fiberglass or cellulose levels out those temperature spikes faster than almost any other retrofit. We install blown-in insulation with dense-pack methods for walls and loose-fill for attics, using Johns Manville and Knauf product lines where the job calls for them.
Blown-In Cellulose
Signs you need it
Your attic insulation is settled below the top of the joists and you can feel heat radiating through the ceiling in late afternoon.
What it costs in Commerce
Blown-in cellulose in Commerce attics usually runs $0.80 to $1.50 per square foot installed at recommended R-values.
How we do it
We blow the cellulose over the existing layer after addressing any air leaks, hitting the R-value we agreed on and checking depth with a gauge.
Blown-In Fiberglass
Signs you need it
You want a dust-free, non-settling attic insulation that holds its R-value in Commerce’s hot, dry attic conditions.
What it costs in Commerce
Blown-in fiberglass in Commerce typically costs $0.90 to $1.70 per square foot installed, including prep.
How we do it
We run the loose-fill through a calibrated blower, building up even coverage across the attic floor and raking high spots as we go.
What Blown-In Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Blown-in cellulose attic (installed, per sq ft) | $0.80 - $1.50 |
| Blown-in fiberglass attic (installed, per sq ft) | $0.90 - $1.70 |
| Dense-pack wall retrofit (installed, per sq ft) | $2.00 - $4.00 |
How long does blown-in insulation last in Commerce?
Fiberglass holds its R-value indefinitely if it stays dry. Cellulose settles somewhat over the first year, which is why we install it slightly above target depth. Call (626) 606-2964 for an attic inspection.
Can you blow insulation into existing Commerce walls?
Yes, through small holes drilled from the interior or exterior, then patched to match. The dense-pack method works well for uninsulated wall cavities in aging Commerce homes.
Radiant Barrier Installation in Commerce
Radiant barrier installation in Commerce targets the single biggest heat source in local attics: the sun hammering dark roof shingles and flat roofing membranes all afternoon. Because Commerce’s heat island keeps ambient temperatures high even after sunset, a foil radiant barrier under the roof deck reflects radiant heat before it reaches your insulation, which means the insulation you have actually works. We install radiant barrier installation as a standalone fix or paired with new attic insulation, using reinforced foil that holds up in hot, dry attics.
Attic Radiant Barrier
Signs you need it
Your attic hits well over 130°F on summer afternoons and the insulation below the roof deck is hot to the touch by evening.
What it costs in Commerce
Attic radiant barrier in Commerce typically ranges $0.50 to $1.00 per square foot installed, depending on roof geometry.
How we do it
We staple the foil to the underside of the rafters or lay it over the attic floor joists, leaving an air gap on the reflective side so it performs as designed.
Radiant Barrier Roof Deck
Signs you need it
You have a low-slope or flat roof and want to cut radiant heat gain before it reaches the conditioned space below.
What it costs in Commerce
Roof-deck radiant barrier in Commerce usually runs $0.60 to $1.20 per square foot installed.
How we do it
We install the barrier directly against the roof deck with an air gap facing inward, inspecting for existing moisture damage before any foil goes up.
What Radiant Barrier Installation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic radiant barrier (installed, per sq ft) | $0.50 - $1.00 |
| Roof deck radiant barrier (installed, per sq ft) | $0.60 - $1.20 |
| Full attic retrofit with barrier and insulation top-up | $1,500 - $4,000 |
Does radiant barrier actually work in Commerce?
Yes, in attics where most heat gain is radiant rather than conductive. The reflective foil blocks a large share of the sun’s heat before it can load your insulation. Call (626) 606-2964 to see if your roof orientation makes it worth it.
Can I install radiant barrier myself?
Foil in an attic is low-voltage work, but the attic itself is not. Steep roof pitches, low clearances, and hot surfaces in a Commerce summer make this a professional job for safety and a proper air gap.
Insulation Removal & Replacement in Commerce
Insulation removal and replacement in Commerce usually starts with something older than the building’s current use: pre-1980 loose-fill or spray-applied products that may contain asbestos, or batt insulation ruined by roof leaks and rodent activity. In Commerce specifically, that asbestos risk is higher than in neighboring cities because so many industrial buildings date to the 1950s through 1970s. We remove and replace with insulation removal and replacement handled as a single job: survey, removal, disposal, and new material installed to current R-value standards.
Attic Insulation Removal
Signs you need it
Your attic insulation is compressed, water-stained, or full of rodent droppings, and it no longer holds its original R-value.
What it costs in Commerce
Attic insulation removal in Commerce typically costs $1.00 to $2.00 per square foot, including bagging and disposal.
How we do it
We vacuum the old material out with a commercial HEPA-filtered system, bag it on site, and prep the attic for new insulation the same day.
Vermiculite & Old Insulation Removal
Signs you need it
You have loose, pebbly vermiculite in an older building, which may contain asbestos and should never be disturbed casually.
What it costs in Commerce
Vermiculite and suspect-material removal in Commerce usually runs $2.00 to $4.00 per square foot due to testing and controlled handling.
How we do it
We test first, then coordinate licensed abatement if needed, then remove the material under negative pressure with full containment and disposal documentation.
What Insulation Removal & Replacement Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic insulation removal (per sq ft) | $1.00 - $2.00 |
| Vermiculite or suspect-material removal (per sq ft) | $2.00 - $4.00 |
| Full removal and replacement (small residential attic) | $2,500 - $6,000 |
How do I know if my Commerce insulation has asbestos?
You cannot tell by looking. Pre-1980 loose-fill and spray-applied products should be tested before any disturbance. We arrange testing and abatement coordination before removal starts. Call (626) 606-2964 to schedule.
Can you remove and replace insulation the same day?
In most attics, yes. Removal, prep, and new blown-in insulation can all happen in one visit. Larger or contaminated jobs may take two days depending on containment requirements.
Attic Air Sealing in Commerce
Attic air sealing in Commerce fixes the hidden leakage paths that pull hot, dusty attic air into living spaces and push cooled air out through the roof. The older wood-frame homes in Commerce were never air-sealed when built, and decades of settling have opened gaps around top plates, can lights, and duct boots. Closing those leaks before adding insulation makes every R-value you pay for count, and it keeps the industrial air outside where it belongs. We handle attic air sealing with foam, caulk, and rigid barriers, always before new insulation goes in.
Attic Floor Air Sealing
Signs you need it
Your upstairs rooms smell dusty or you can feel warm air pushing down through ceiling fixtures in summer.
What it costs in Commerce
Attic floor air sealing in Commerce typically runs $250 to $800 depending on attic accessibility and the number of penetrations.
How we do it
We move insulation aside, seal every penetration through the attic floor with foam or caulk, then re-spread the insulation to design depth.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights are hot to the touch, or you can feel air blowing around ceiling registers that should be sealed to the duct.
What it costs in Commerce
Can light and duct boot sealing in Commerce usually costs $15 to $40 per fixture or boot, including materials.
How we do it
We install rated covers over non-IC cans, seal the boot-to-drywall gap with mastic and foam, and verify the connection with a smoke pencil.
What Attic Air Sealing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic floor air sealing (full job) | $250 - $800 |
| Can light or duct boot sealing (per fixture/boot) | $15 - $40 |
| Full attic sealing plus insulation top-up | $1,200 - $3,500 |
Does air sealing really matter if I’m adding insulation?
Yes, more than most people think. Insulation slows heat transfer but does not stop air movement, and leaky attics move large volumes of air. In Commerce, sealing first keeps the heat island out. Call (626) 606-2964 for an audit.
How long does attic air sealing take?
A typical Commerce attic takes one crew visit of four to six hours. Larger homes or heavily penetrated attics may take a full day.
Wall Insulation in Commerce
Wall insulation in Commerce is a retrofit game because so many local homes and older commercial buildings were built when wall insulation was optional. The 1940s to 1960s wood-frame houses frequently have empty wall cavities, which means the walls themselves act as a heat exchanger all summer and a cold shell all winter. Fixing that requires either injection foam or drill-and-fill methods, not new-construction batts. Our wall insulation work in Commerce covers both approaches, plus interior soundproofing for buildings near truck routes and rail spurs.
Drill & Fill Wall Insulation
Signs you need it
Your walls are cold in winter and hot in summer, and knocking on the drywall sounds hollow compared to a known insulated wall.
What it costs in Commerce
Drill-and-fill wall insulation in Commerce typically costs $2.00 to $4.00 per square foot of wall area.
How we do it
We drill small access holes from inside or outside, blow dense-packed cellulose or fiberglass into each cavity, then patch and texture the holes to match.
Injection Foam Wall Insulation
Signs you need it
You need wall insulation that also air-seals the cavity, or your wall cavities are irregular and difficult to fill with loose-fill alone.
What it costs in Commerce
Injection foam wall insulation in Commerce usually runs $3.00 to $6.00 per square foot installed.
How we do it
We inject slow-rise foam through small holes in the wall, letting it expand to fill the cavity and seal gaps as it cures.
What Wall Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Drill-and-fill wall retrofit (per sq ft) | $2.00 - $4.00 |
| Injection foam wall insulation (per sq ft) | $3.00 - $6.00 |
| Full wall retrofit for a small Commerce home | $2,500 - $6,000 |
Will wall insulation reduce noise from trucks in Commerce?
Yes, especially dense-pack cellulose and injection foam, which add mass and dampen sound transmission. For buildings near the 5 freeway or warehouse loading docks, it makes a real difference. Call (626) 606-2964 for an assessment.
Can you insulate walls without removing drywall?
Yes, both drill-and-fill and injection foam work through small access holes, so no drywall demolition is required. The holes get patched, textured, and painted to match.
Attic Cleaning & Rodent Proofing in Commerce
Attic cleaning and rodent proofing in Commerce deals with the double problem of an aging housing stock and a built environment that gives rodents steady cover. Warehouses, rail spurs, and dense commercial blocks mean rats and mice are always nearby, and the older wood-frame homes have plenty of entry points. Droppings, nesting material, and chewed wiring are common finds in Commerce attics. Our attic cleaning and rodent proofing work removes the mess, sanitizes the space, and closes the entry points so the problem stays gone.
Attic Cleanout
Signs you need it
You can smell animal odor from the attic or see droppings, nesting debris, and disturbed insulation when you peek up through the hatch.
What it costs in Commerce
Attic cleanout in Commerce typically runs $300 to $800, depending on attic size and the amount of debris.
How we do it
We remove contaminated insulation and debris, bag everything on site, and dispose of it properly before any sanitizing starts.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find droppings or gnawed wires, or see daylight coming through gaps at the roofline.
What it costs in Commerce
Rodent proofing and exclusion in Commerce usually costs $400 to $1,200 per building, depending on entry points and roofline length.
How we do it
We seal every entry point with steel mesh, hardware cloth, and foam, then check the roof vents, soffits, and utility penetrations one by one.
What Attic Cleaning & Rodent Proofing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic cleanout and debris removal | $300 - $800 |
| Rodent proofing and exclusion (full job) | $400 - $1,200 |
| Full cleanout, sanitizing, and exclusion package | $900 - $2,500 |
Do I need to remove insulation after rodents were in my Commerce attic?
Usually yes. Rodent droppings and urine contaminate the insulation, and the odor will linger until the material is removed and replaced. Call (626) 606-2964 for an attic inspection and a firm quote.
How soon can you start a cleanout in Commerce?
We can usually schedule a cleanout within a few business days. If the odor or activity is severe, we’ll do what we can to get a crew out sooner.
Home Energy Audit in Commerce
A home energy audit in Commerce shows exactly where your building is losing conditioned air and where your utility dollars are going. For local homeowners, that usually means an attic with thin or settled insulation and a stack of air leaks around the ceiling plane. For commercial tenants, it’s often the roof deck and loading dock seals. Our home energy audit uses blower door testing, thermal imaging, and duct leakage measurements, and we walk you through the findings in plain language before you spend a dollar on fixes.
Blower Door Test
Signs you need it
Your energy bills spike in summer and winter while the thermostat stays set, or you can feel drafts near windows and baseboards.
What it costs in Commerce
A blower door test in Commerce typically costs $200 to $450, often rolled into a full audit.
How we do it
We mount the blower door in an exterior door frame, depressurize the building, and measure total air leakage in cubic feet per minute.
Thermal Imaging Inspection
Signs you need it
Certain rooms stay hot no matter what the AC does, or you suspect missing insulation in walls or ceilings but cannot confirm it.
What it costs in Commerce
Thermal imaging in Commerce usually runs $150 to $300 as part of an audit, depending on building size.
How we do it
We scan interior and exterior surfaces with an infrared camera, mapping cold and hot spots that point to missing insulation, air leaks, or moisture.
What Home Energy Audit Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Full home energy audit (blower door plus thermal imaging) | $350 - $700 |
| Blower door test only | $200 - $450 |
| Thermal imaging inspection only | $150 - $300 |
What do I get after a Commerce energy audit?
You get a prioritized list of fixes with measured leakage numbers and thermal images, plus our honest take on what’s worth doing first. Call (626) 606-2964 to schedule an audit.
Is an energy audit worth it before insulation work?
Yes, because it tells us exactly what to fix so you don’t pay for insulation that’s solving the wrong problem. In Commerce’s heat, that precision is worth every dollar.

What Commerce Customers Say
"Crawl space was wet every spring. They laid the heavy liner, sealed the vents, and put a dehumidifier down there. Floors are warm and the moisture meter he left reads fine now. He still answers when I text him a reading."
- Devon Pierce"Radiant barrier and new insulation in one visit. Walt explained what the foil actually does and what it does not, which nobody else bothered to. Electric bill in July was the lowest it has been in this house."
- Nadia Haddad"Walt came out himself, stuck his head in the attic, and told me I had about four inches where I needed fourteen. No sales pitch, just the number and what it would cost to fix it. Crew was here two days later."
