Insulation Company in Commerce, CA
Blown in insulation is the most common retrofit we install in Commerce, because most homes here were built between the 1950s and 1970s with thin original attic insulation, if any at all. The work here is different from coastal LA: Commerce sits against the 5 and 710 freeways and active rail lines, so insulation has to manage attic heat gain, air leakage, and the constant low-frequency rumble of truck traffic. Shelter Insulation has served Commerce since 2016, and we plan every job around the specific wall cavities, roof pitches, and noise exposure this city throws at a house.

Why Commerce Homes Are Different
Commerce’s residential blocks are woven directly into one of the densest logistics corridors in Los Angeles County. The homes are largely mid-century stucco-on-frame single-family houses and small duplex walk-ups, many of them post-war tract construction from the 1950s through the 1970s. Those homes typically have 2×4 exterior walls with minimal cavity depth, original or barely-updated fiberglass batt in the attic, and uninsulated garages or additions that were converted from storage. Wall cavities are often narrower than modern code assumes, which changes what products make sense.
The climate works against these older homes. Commerce gets the full inland San Gabriel Valley heat through long, dry summers, often running hotter than downtown LA. Attics become heat reservoirs, pushing conditioned air out and forcing air conditioners to run constantly from June through October. Winter is mild enough that cold-weather R-value is rarely the concern; the real priority is keeping radiant heat out of the attic and sealing the ceiling plane. Add freeway and rail proximity and you get the other half of the problem: airborne noise and diesel particulate infiltration through gaps in the building envelope. Homes here need a different insulation strategy than a house in a quiet suburban subdivision.
Our Main Commerce Services
Most Commerce homeowners call us about two things: improving attic performance against that summer heat, and sealing the home against air and noise intrusion.
Attic Insulation in Commerce
Attic insulation in Commerce is usually a retrofit problem: the original batt has settled, compressed, or was never adequate for the heat load. We inspect the attic floor, check for air leaks around penetrations, and upgrade to a level that actually changes how hard the air conditioner works in August. On older Commerce homes, attic work almost always includes sealing top plates, can lights, and duct chases before insulation goes in. Air sealing is what separates a real comfort improvement from a paper upgrade. See Attic Insulation in Commerce for the full breakdown of materials and costs.
Spray Foam Insulation in Commerce
Spray foam earns its place in Commerce where air sealing matters as much as R-value: rim joists, crawlspace ceilings, and open attic rooflines on homes with converted attic spaces. Closed-cell foam also stiffens old framing and cuts down on the low-frequency vibration that travels through roof decks near the rail yards. We specify open-cell or closed-cell based on the cavity and the problem, not on what is easiest to spray. Spray Foam Insulation in Commerce covers when foam makes sense and what it costs.

Blown In Insulation in Commerce
Blown in insulation is the workhorse retrofit for Commerce’s older homes. Loose-fill fiberglass and cellulose settle into irregular attic cavities, around old framing, and over existing batts in a way that batt insulation cannot, and it brings a 1950s attic up to a meaningful R-value without opening walls. Because Commerce homes often have original or minimal insulation and attics that bake under inland heat, blown in insulation combined with air sealing delivers the largest single change a homeowner can make to summer comfort and AC load.
We carry GreenFiber cellulose and Owens Corning loose-fill fiberglass because they behave differently: cellulose packs denser and blocks more airflow, while fiberglass is lighter and easier to top up later. The right choice depends on the attic access, the existing insulation, and whether there are air leaks we need to address first. See Blown In Insulation for our full service details.
Cellulose Insulation
Signs you need it
Your attic has thin, settled, or missing insulation and the ceiling feels warm to the touch on summer afternoons in Commerce.
What it costs in Commerce
Cellulose attic insulation in Commerce typically runs $1.10 to $1.75 per square foot before any air sealing work.
How we do it
We prep the attic, seal ceiling-plane air leaks, then blow GreenFiber cellulose to a consistent, measured depth across the full attic floor.
Blown In Attic Insulation
Signs you need it
The existing attic insulation is below the top of the joists, or you can see the ceiling framing from inside the attic.

Blown in attic insulation in Commerce generally falls between $1.10 and $1.70 per square foot for the full loose-fill installation.
How we do it
We remove or work around existing batts, air seal the penetrations, and blow new material to a uniform depth that meets the target R-value for the LA basin.

What it costs in Commerce
Blown in cellulose insulation in Commerce typically ranges from $1.10 to $1.75 per square foot depending on depth and access.
How we do it
We run a fill hose to the attic access, meter the cellulose through a calibrated blower, and build depth in layers to avoid overloading the ceiling.
What Blown In Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Cellulose attic insulation | $1.10 – $1.75 per sq ft |
| Blown in attic insulation (fiberglass or cellulose) | $1.10 – $1.70 per sq ft |
| Air sealing before blown in insulation | Quoted per project, based on attic size and leak count |
How long does blown in insulation last in Commerce?
Cellulose and loose-fill fiberglass both hold their R-value for decades if the attic stays dry. In Commerce, heat and dust don’t degrade the material itself; the bigger risk is settling, which is why we install to a slightly higher initial depth.
Can you blow insulation over old batts in a Commerce home?
Yes, in most cases. We check the existing batt for moisture or rodent damage first, then blow loose-fill over it to raise total R-value. Air sealing happens before any new material goes in. Call (855) 341-3373 for a specific answer about your attic.
Brands We Service in Commerce
Shelter Insulation installs products from eight manufacturers, and the ones we most often specify in Commerce are GreenFiber cellulose, Owens Corning loose-fill fiberglass, and Johns Manville batts where a cavity calls for a batt instead of blown material. Our crews carry common density and R-value options for these brands on the truck, so a typical Commerce attic job doesn’t wait on a supply run. Learn more about our brands.

In Commerce, the two variables that move price most are attic access and air sealing scope. Older tract homes with tight scuttle holes or HVAC equipment blocking the attic floor take longer to prep, and a ceiling plane with dozens of can lights or duct penetrations needs more sealing time before any insulation goes in. You get a written, line-item quote before work starts, and that quote is the price, not an opening bid.

In most cases, adding insulation to an existing attic does not require a city permit in Commerce, because it is not structural work. The exception is when insulation is part of a larger addition, attic conversion, or garage-to-living-space retrofit, where the city may require a permit for the whole scope. We can tell you which situation applies to your project during the estimate.
Yes. The same Shelter Insulation crew handles attic insulation, spray foam, and blown in work, so you are not coordinating separate contractors for different parts of the home. One point of contact, one warranty conversation, one company accountable for the whole envelope.
