Insulation in Commerce, CA
Spray foam insulation in Commerce is the most common service we handle here, and the work is heavily shaped by the city’s industrial character. Commerce sits inland, away from the coastal marine layer, so summer highs regularly push into the mid-to-upper 90s. That heat bakes warehouse roofs, cold-storage facilities, and the smaller stock of older homes alike. For homeowners and facility managers dealing with cooling bills that spike every August, spray foam is often the fastest path to real relief. Call (747) 246-7237 and a live person answers, 24/7.
Why Commerce Homes Are Different
Commerce is one of the most industrialized cities in Los Angeles County, and that changes everything about how we approach insulation here. Most of the built environment is large-span warehouses, distribution centers, food-processing plants, and cold-storage facilities with concrete tilt-up walls and metal roofs that absorb and hold heat. The residential stock is small and mostly mid-20th-century construction with minimal original wall and attic insulation. What this means in practice: we spend a lot of time retrofitting flat-roof warehouse envelopes and wrapping or insulating mechanical systems, and less time in residential attics than we would in Montebello or Pico Rivera. The heat load is real, and the energy consequences of under-insulated buildings show up fast in July.
A distinct issue in Commerce’s industrial corridor is failing pipe insulation on aging refrigerated warehouses and food-processing facilities. When pipe insulation fails, condensation forms, energy losses climb, and perishable inventory is at risk. That liability-driven urgency is something you simply don’t see in residential-heavy markets. The one down the road understands these buildings because we’ve been crawling through them for years.
Our Main Commerce Services
Two services generate most of our calls from Commerce homeowners and small commercial operators. Both are covered by our lifetime Done Right Promise.
Attic Insulation in Commerce
Older Commerce homes, most built in the 1950s and 60s, often have a thin layer of original fiberglass batts that has settled and lost its R-value. Summer attic temperatures here can exceed 140°F, so a top-up or full replacement makes an immediate difference in how hard the air conditioner runs. We also handle attic insulation for the small commercial buildings that need to keep offices cool under flat asphalt roofs. See Attic Insulation in Commerce for a full breakdown of what this looks like here.
Crawl Space Encapsulation & Vapor Barrier in Commerce
Commerce sits on flat, often hard-packed ground, and the older homes with raised foundations can trap moisture under the floor. Damp crawl spaces push humidity into living areas, and in a city where summer heat already stresses cooling systems, that extra moisture makes everything worse. We install heavy vapor barriers and encapsulation systems that keep the space dry and the air cleaner. Details on Crawl Space Encapsulation & Vapor Barrier in Commerce.

Spray Foam Insulation in Commerce
Spray foam gives Commerce buildings the best air-seal per square foot of any insulation we install, and in this heat it pays for itself through lower cooling bills. Metal warehouse roofs and concrete tilt-up walls absorb heat all day, and spray foam’s continuous air barrier stops that heat from transferring into the conditioned space. We work with closed-cell and open-cell systems from Icynene and Demilec. Learn more about Spray Foam Insulation options we install.
Closed-Cell Spray Foam
Signs you need it
High cooling bills and warm interior wall surfaces on summer afternoons signal missing or failed insulation in wall cavities and roof decks.
What it costs in Commerce
Closed-cell spray foam typically runs $2.50 to $5.00 per board foot installed, depending on depth and access in Commerce.
How we do it
We seal the target area, apply foam to the required depth, then trim and inspect every square foot.
Spray Foam Roof Deck
Signs you need it
Radiant heat pouring through the ceiling and attic temperatures that spike early in the day point to an uninsulated roof deck.
What it costs in Commerce
Roof deck spray foam in Commerce usually runs $3.50 to $7.00 per board foot, though large flat roofs can push lower on a per-foot basis.
How we do it
We apply foam directly to the underside of the roof deck, creating an unvented attic assembly that keeps heat out.
What Spray Foam Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Open-cell spray foam | $0.80 - $1.80 per board foot |
| Closed-cell spray foam | $2.50 - $5.00 per board foot |
| Roof deck spray foam | $3.50 - $7.00 per board foot |
Is spray foam worth it for a small Commerce home?
Yes. Even a small 1,200-square-foot home in Commerce sees meaningful cooling savings because our inland heat loads are extreme. Call (747) 246-7237 for a free estimate on your specific house.
Can you spray foam a warehouse roof in Commerce?
Yes, we regularly foam large flat warehouse roofs across Commerce’s industrial corridor. Upfront pricing is provided, and the Done Right Promise covers the workmanship. Call (747) 246-7237 for a site visit.
Blown-In Insulation in Commerce
Blown-in insulation is the most practical upgrade for older Commerce homes with finished walls and attics that would be expensive to open up. The tiny residential stock here, mostly built mid-century, typically lacks enough attic depth to resist the inland summer heat. Blowing in cellulose or fiberglass gets R-value into finished spaces fast and cleanly. We stock Johns Manville and Knauf blown-in products. Details on Blown-In Insulation we install.
Blown-In Cellulose
Signs you need it
Thin, settled attic insulation that sits below the floor joists means you need a top-up or full new layer.
What it costs in Commerce
Blown-in cellulose in Commerce generally runs $1.50 to $2.50 per square foot installed.
How we do it
We blow loose-fill cellulose to the full target depth and density, then level it for even coverage.
Dense-Pack Wall Insulation
Signs you need it
Finished walls that feel warm inside during Commerce’s afternoon heat indicate empty or settled wall cavities.
What it costs in Commerce
Dense-pack wall insulation runs $2.00 to $3.50 per square foot of wall area in Commerce.
How we do it
We drill access holes, blow fiberglass or cellulose at high density, and patch the holes cleanly.
What Blown-In Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Blown-in cellulose | $1.50 - $2.50 per sq ft |
| Blown-in fiberglass | $1.00 - $2.00 per sq ft |
| Dense-pack wall insulation | $2.00 - $3.50 per sq ft |
How much insulation should a Commerce attic have?
For inland Commerce heat we recommend R-38 to R-60 in the attic. Most older homes here have R-11 or less. Call (747) 246-7237 and we’ll check yours free.
Can you blow insulation into finished walls without major demo?
Yes. Dense-pack blows through small drilled holes without removing drywall. We patch the holes when we’re done. Call (747) 246-7237 to see if your walls qualify.
Radiant Barrier Installation in Commerce
Radiant barrier works well in Commerce because our problem is direct solar gain landing on roofs, not just hot air. A radiant barrier reflects radiant heat away from the attic, which is exactly the kind of heat that builds up all afternoon in this city’s inland location. It’s a strong complement to blown-in or spray foam insulation on older Commerce homes and small commercial buildings. We install durable foil products. See Radiant Barrier Installation options.
Attic Radiant Barrier
Signs you need it
An attic that stays hot well into the evening and rooms directly below that never quite cool down signal strong radiant heat gain.
What it costs in Commerce
Attic radiant barrier in Commerce typically runs $1.50 to $2.50 per square foot of attic floor area.
How we do it
We fasten foil barrier to the underside of the rafters or over existing insulation, with ventilation gaps left intact.
Radiant Barrier Roof Deck
Signs you need it
High roof surface temperatures and extreme attic heat in the afternoon on a Commerce summer day indicate direct solar loading.
What it costs in Commerce
Roof deck radiant barrier work runs $2.00 to $3.50 per square foot in Commerce, depending on roof pitch and access.
How we do it
We install reflective material directly under the roof deck before or during insulation work.
What Radiant Barrier Installation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic radiant barrier | $1.50 - $2.50 per sq ft |
| Roof deck radiant barrier | $2.00 - $3.50 per sq ft |
| Radiant barrier with ventilation | $2.50 - $4.00 per sq ft |
Does radiant barrier work on a flat warehouse roof in Commerce?
Yes, but installation differs from a pitched attic. We run the barrier under the metal or membrane roof line where feasible. Call (747) 246-7237 for specifics on your building.
Is radiant barrier enough on its own in Commerce?
Usually not. It reduces radiant gain but doesn’t stop conductive heat. We pair it with insulation for best results in this heat. Call (747) 246-7237 for a combined quote.
Insulation Removal & Replacement in Commerce
Old, compacted, or contaminated insulation has to come out before new material goes in, and in Commerce this often means dealing with years of dust, rodent droppings, and failed material in older homes and commercial spaces alike. Replacing old insulation is the only real fix when it’s wet, moldy, or flattened. We do full containment removal and replacement. More on Insulation Removal & Replacement.
Attic Insulation Removal
Signs you need it
Thin, dark, flattened fiberglass that no longer fluffs up or has visible rodent waste in it should come out, not get topped up.
What it costs in Commerce
Attic insulation removal in Commerce usually costs $1.50 to $3.00 per square foot, before new material goes in.
How we do it
We vacuum old material into sealed containment bags, clean the cavity, and prep it for replacement.
Contaminated Insulation Removal
Signs you need it
Droppings, heavy dust, or musty odor in the insulation means it has been compromised and must be removed before sanitizing.
What it costs in Commerce
Contaminated insulation removal in Commerce runs $2.00 to $4.00 per square foot, reflecting the extra containment and disposal steps.
How we do it
We set up HEPA-filtered vacuums and full containment, remove all affected material, and sanitize the area before re-insulating.
What Insulation Removal & Replacement Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic insulation removal | $1.50 - $3.00 per sq ft |
| Contaminated removal | $2.00 - $4.00 per sq ft |
| Replacement installation | $1.50 - $3.00 per sq ft |
How do I know if my insulation needs removal, not a top-up?
If it’s wet, rodent-infested, or compressed below the floor joists, it needs to come out. Topping up bad material traps the problem. Call (747) 246-7237 for an honest assessment.
Can you remove vermiculite insulation in Commerce?
Yes, we remove vermiculite and old insulation using proper containment procedures. Do not disturb suspected vermiculite yourself. Call (747) 246-7237 and we’ll handle it safely.
Attic Air Sealing in Commerce
Air sealing stops the stack effect that pulls hot outside air into a Commerce building and conditioned air out through gaps around pipes, wires, can lights, and top plates. In this inland heat, an unsealed attic can rob a cooling system of a huge share of its effectiveness. Old Commerce homes are full of unsealed penetrations from decades of remodels. We seal before insulating, every time. Details on Attic Air Sealing.
Top Plate & Penetration Sealing
Signs you need it
Dusty attic insulation around wire and pipe penetrations, along with upstairs rooms that never cool, signal air leakage at the top plates.
What it costs in Commerce
Top plate and penetration sealing in Commerce typically runs $1.00 to $2.00 per square foot of attic floor.
How we do it
We foam or caulk every penetration and seam between living space and attic before blowing new insulation.
Can Light & Duct Boot Sealing
Signs you need it
Hot air pouring through recessed light fixtures and gaps around duct boots is a sign the attic is depressurizing the house.
What it costs in Commerce
Can light and duct boot sealing runs $15 to $30 per fixture or boot in Commerce, depending on accessibility.
How we do it
We seal each fixture with rated covers or boxes and seal every duct connection to the ceiling plane.
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 sealing | $15 - $30 per fixture |
| Duct boot sealing | $15 - $30 per boot |
Should I air seal before adding insulation in Commerce?
Always. Insulation without air sealing is like a down jacket with holes. We seal first, then blow. Call (747) 246-7237 and we’ll inspect yours as part of the quote.
What are the biggest air leaks in an old Commerce house?
Top plates, plumbing and wiring penetrations, can lights, and the attic hatch are the worst. We seal all of them before insulating. Call (747) 246-7237 for a thorough air-seal audit.
Wall Insulation in Commerce
Wall insulation in Commerce matters because most older homes here have empty or under-filled wall cavities. When afternoon heat hits the exterior walls, the rooms warm up fast and the A/C runs constantly. Filling walls is a one-time fix that pays back for decades. We use injection foam and drill-and-fill methods that don’t require tearing out drywall. More on Wall Insulation.
Injection Foam Wall Insulation
Signs you need it
Walls that radiate heat on hot afternoons and rooms that heat up within an hour of the sun hitting that wall point to empty cavities.
What it costs in Commerce
Injection foam wall insulation in Commerce typically runs $3.00 to $5.00 per square foot of wall area.
How we do it
We drill small holes in each stud bay, inject slow-rise foam to fill the cavity, and patch the holes to match.
Interior Wall Soundproofing
Signs you need it
Traffic noise from the 5 and 710 corridors or noise bleed between rooms means the walls need dense material added.
What it costs in Commerce
Interior wall soundproofing in Commerce runs $2.50 to $4.00 per square foot, depending on the product used.
How we do it
We dense-pack or inject sound-dampening insulation into interior wall cavities and verify the result.
What Wall Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Injection foam wall | $3.00 - $5.00 per sq ft |
| Drill & fill wall | $2.00 - $3.50 per sq ft |
| Interior soundproofing | $2.50 - $4.00 per sq ft |
Can you insulate my existing Commerce walls without tearing out drywall?
Yes. Injection foam and drill-and-fill both work through small holes that get patched afterward. No demolition needed. Call (747) 246-7237 for a wall assessment.
Will wall insulation really lower my cooling bill in Commerce?
It will reduce heat gain through the building envelope, which cuts how hard your A/C works. Most Commerce homes see a noticeable difference. Call (747) 246-7237 for specifics on your walls.
Attic Cleaning & Rodent Proofing in Commerce
Attic cleaning and rodent proofing in Commerce is about removing the contamination that rodents leave behind and sealing the entry points so they can’t come back. Older Commerce homes with attic vents and roof joints that have shifted over decades are common entry points, and the industrial surroundings here support active rodent populations. We clean, sanitize, and exclusion-seal. Details on Attic Cleaning & Rodent Proofing.
Attic Cleanout
Signs you need it
Droppings in the insulation, stale urine odor, and nesting debris indicate an attic that needs a full cleanout, not just new insulation on top.
What it costs in Commerce
Attic cleanout in Commerce typically runs $2.00 to $3.50 per square foot, including removal of old insulation and debris.
How we do it
We remove all contaminated material using HEPA vacuums and containment, then dispose of it properly.
Rodent Proofing & Exclusion
Signs you need it
Repeated rodent activity, chewed wires, and visible entry gaps at eaves and vents mean the building needs exclusion sealing, not just trapping.
What it costs in Commerce
Rodent proofing and exclusion in Commerce runs $500 to $1,500 depending on the number and type of entry points found.
How we do it
We identify every entry point, seal them with materials rodents cannot chew through, and verify the building is secure.
What Attic Cleaning & Rodent Proofing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic cleanout | $2.00 - $3.50 per sq ft |
| Sanitizing & decontamination | $1.50 - $3.00 per sq ft |
| Rodent proofing & exclusion | $500 - $1,500 per project |
How quickly can you clean out an attic in Commerce?
Most residential attics are cleaned and sanitized in a single day. Larger commercial spaces take longer. Call (747) 246-7237 to schedule a walkthrough and get a firm timeline.
Is rodent proofing permanent?
The sealing work is designed to be permanent as long as the building envelope stays intact. We inspect and verify every job. Call (747) 246-7237 for details.
Home Energy Audit in Commerce
A home energy audit in Commerce tells you exactly where your cooling dollars are going. With the inland heat and older housing stock here, most buildings have a handful of fixable inefficiencies that add up to big energy loss. We measure, test, and give you a plain-language report on what to fix and in what order. More on Home Energy Audit.
Blower Door Test
Signs you need it
Rooms that never hold temperature and cooling bills that seem disconnected from your thermostat settings point to excessive air leakage.
What it costs in Commerce
A blower door test in Commerce typically runs $200 to $400 as part of a full audit.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure total air leakage.
Thermal Imaging Inspection
Signs you need it
Hot or cold spots on walls and ceilings that you can feel but can’t explain point to missing insulation in specific cavities.
What it costs in Commerce
Thermal imaging inspection runs $150 to $300 in Commerce, depending on building size.
How we do it
We scan every ceiling, wall, and floor surface with an infrared camera and document every anomaly.
What Home Energy Audit Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Blower door test | $200 - $400 |
| Thermal imaging inspection | $150 - $300 |
| Duct leakage test | $100 - $250 |
Is an energy audit worth the cost in Commerce?
For most older Commerce homes, yes. The audit finds specific leaks and gaps, so you fix the right things first instead of guessing. Call (747) 246-7237 to book one.
How long does a home energy audit take in Commerce?
A standard residential audit takes two to three hours. You get a written report the same week. Call (747) 246-7237 to schedule.

What Commerce Customers Say
"We had the walls of our old house filled with foam through small holes from the outside. Patched and painted the same afternoon. The bedrooms hold heat now and the furnace runs a lot less."
- Linda Baumgartner"Air sealing first, then blown-in over the top. He found a bathroom fan venting straight into the attic and fixed that too. Written price before they started, same price when they finished."
- Arjun Mehta"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
