Insulation Company in Commerce, CA
Blown in insulation is the workhorse fix for Commerce homes built between the 1940s and 1960s, where original wall cavities often sit empty and flat or low-pitch roofs bake under inland Los Angeles sun all summer. We approach every Commerce job by asking what the house actually needs: heat-gain resistance, air sealing, or both. Airtight Insulation Co has served Commerce since 2011, and we stock eight manufacturer brands so the material matches the condition of the house, not our inventory sheet.

Why Commerce Homes Are Different
Commerce is a dense, flat industrial city of warehouses, factories, and mid-century tract homes with a strong working-class Latino community. Insulation work here is less about cold and more about stopping heat gain in low-slope warehouse roofs and keeping aging homes comfortable without AC overkill. The housing stock is mostly 1940s-1960s stucco tract homes and 1960s-70s low-rise commercial buildings. Many homes still have original wall cavities with little or no insulation, and flat or low-pitch roofs that bake in the sun from June through September.
Because Commerce sits in the inland Los Angeles basin, summers are hot and dry while winters stay mild. The main insulation priority is reflecting heat from intense sun, especially on attics and flat roofs, rather than cold-weather retention. Attic insulation in Commerce homes often needs a radiant barrier or extra attention to sun-exposed roof decks because the older attics lack proper intake vents and the summer heat builds up like an oven by midday. We see this pattern in block after block of stucco tract homes where the afternoon sun hits the roof deck and turns the attic into a heat sink that radiates into living spaces until well after dark.
Our Main Commerce Services
Two services account for most of the calls we take from Commerce homeowners and light-commercial property managers: attic insulation and spray foam. Each solves a different problem, and we stock materials for both.
Attic Insulation in Commerce
Attic insulation in Commerce is the first line of defense against the roof deck heat that builds up in older homes and low-rise commercial buildings. We inspect the existing attic, check for proper intake vents, and recommend either blown-in fiberglass or cellulose, often paired with a radiant barrier on sun-exposed roof decks. The goal is to stop heat from radiating down into the living space so the AC doesn’t run all afternoon. Attic Insulation in Commerce covers the full scope of what we do up there.
Spray Foam Insulation in Commerce
Spray foam in Commerce is the air-sealing solution for warehouses, factories, and the occasional attached garage conversion. Open-cell foam works well for interior wall cavities, while closed-cell foam adds structural strength and moisture resistance, which matters on flat commercial roofs that pool water after rain. We carry Icynene and Demilec lines for both formulations, so the recommendation comes from the building’s condition, not from what’s left on the truck. Spray Foam Insulation in Commerce details the difference between open-cell and closed-cell and where each makes sense.

Blown In Insulation in Commerce
Blown in insulation in Commerce is the most practical way to fill the empty wall cavities and attic floors of 1940s-1960s stucco tract homes without tearing out drywall. The inland basin heat means the material has to resist heat gain from above more than cold from below, and loose-fill cellulose or fiberglass does that well when installed at the right density. Our crews work in Commerce regularly and know how these older homes are built, including the flat and low-pitch roofs that make attic access tighter than on newer builds. We cover everything from attic floors to wall retrofits, and our Blown In Insulation hub page explains the material options in depth.
Cellulose Insulation
Signs you need it
Rooms that stay hot into the evening, rising summer electric bills, and wall cavities that feel empty when you knock on the drywall between studs are all signs the original home has little or no insulation left.
What it costs in Commerce
Blown-in cellulose for an existing attic in Commerce typically runs $1.10 to $2.30 per square foot depending on depth and access, with attic air sealing adding $0.60 to $1.10 per square foot.
How we do it
We identify the access point, run a hose from the truck to the attic or wall cavity, and blow GreenFiber cellulose to the target density, checking depth with a gauge as we go.
Blown In Attic Insulation
Signs you need it
If the upstairs or main living space heats up by mid-afternoon and the AC never cycles off, the attic floor insulation is likely too thin or settled flat against the ceiling joists.
What it costs in Commerce
Blown-in attic insulation in Commerce generally falls between $1,100 and $3,400 for a typical 1,200 to 1,800 square foot home depending on product and depth.
How we do it
We inspect the attic for intake vent blockage and air bypasses first, then blow loose-fill fiberglass or cellulose to the depth specified for the existing framing and roof condition.

Is blown in insulation worth it for a Commerce home?
Yes, it usually pays back through summer cooling savings because Commerce attics trap heat from intense sun and older homes have little or no existing insulation. Call (833) 390-7079 to talk about your specific roofline.

What Commerce Customers Say
"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Claudia Morales"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Simone Grant"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
