Insulation Company in Lawndale, CA
Blown in insulation is the most common fix we install in Lawndale, where post-war 1950s and 60s stucco tract homes were built with little or no attic coverage. Most of those houses have R-0 to R-7 up top, which means heat and the marine-layer damp seep straight through. Fontana Insulation has served Lawndale since 2011, and we stock eight insulation brands so the material gets matched to your actual house, not to whatever is on our truck. Call (866) 271-1602 for an estimate.
Why Lawndale Homes Are Different
Lawndale’s housing stock sits in the South Bay marine layer belt, which changes the insulation conversation entirely. Summer heat is rarely the enemy here. The real problem is winter mornings: cool, damp air off the Pacific settles over the city, and it pushes through uninsulated stucco walls and ceilings that were built before California’s first insulation standards. What we see repeatedly in the 90260 and 90261 ZIP codes is condensation, not temperature swing. Attics that were never vented properly trap moisture, bedding insulation gets damp and slumps, and the original single-pane aluminum windows do nothing to stop the cool air from pooling by the floor.
The 1950s through 60s stucco tract homes around Lawndale were put up fast and cheap. Two-by-four walls, shallow 2×6 roof framing, and empty cavities between the drywall and the stucco. Later apartment and condo buildings near the 405 and Artesia corridor from the 70s and 80s are a different animal, usually with some insulation but often nearing the end of its useful life. This is not an upgrade market. This is a close-the-gap market.
Our Main Lawndale Services
Two things bring most Lawndale homeowners to us: attics that never were insulated and air-sealing jobs in walls and crawlspaces where fiberglass alone gets outmatched.
Attic Insulation in Lawndale
Attics in Lawndale’s older stucco houses are tight, low, and often contaminated with decades of dust and rodent activity from the damp climate. Batts we cut on-site to fit the 2×6 framing rather than ordering standard sizes that will not sit right. We check for moisture damage first, seal the ceiling plane where needed, then bring the attic to an R-value suited to this climate. Attic Insulation in Lawndale
Spray Foam Insulation in Lawndale
Spray foam earns its keep in Lawndale on the uninsulated 2×4 wall cavities and the floor systems over damp crawlspaces. Closed-cell foam does double duty here: it blocks the cool overnight air and it acts as a vapor barrier against the marine-layer moisture that rots fiberglass over time.

Blown In Insulation in Lawndale
Blown in insulation is the most practical answer for most Lawndale attics built between 1950 and 1970. Those houses went up with either no attic insulation or a thin, deteriorated layer that stopped doing its job years ago. Loose fill fills the framing bays and covers the nooks around electrical boxes and ducting that batts leave exposed. We blow fiberglass or cellulose to a measured depth, because the damp climate here means coverage has to be even to hold back condensation. Blown In Insulation is an in-house service, never subcontracted.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the joists, or you can feel cool drafts near interior walls on winter mornings.
What it costs in Lawndale
Cellulose attic work in Lawndale typically runs $1.20 to $2.30 per square foot installed, depending on depth and how much old material has to come out first.
How we do it
We seal the ceiling penetrations, set depth markers, then blow GreenFiber cellulose to the target R-value, checking density as we go so it does not settle too soon.
Blown In Fiberglass Insulation
Signs you need it
You see bare drywall in the attic and uneven, discolored patches of old insulation that has stayed damp from Lawndale’s marine layer.
What it costs in Lawndale
Blown in fiberglass in Lawndale ranges from $0.90 to $1.80 per square foot installed for a typical pre-1970 attic.
How we do it
We pull any wet or rodent-soiled material, air-seal, then blow fiberglass at the density the framing will hold, making sure the shallow 2×6 bays are filled edge to edge.
What Blown In Insulation Costs in Lawndale
| Item | Typical range in Lawndale |
|---|---|
| Blown in fiberglass attic insulation | $0.90 – $1.80 per sq ft |
| Cellulose attic insulation | $1.20 – $2.30 per sq ft |
| Attic air sealing before blow-in | $400 – $900 flat |
Older Lawndale houses push cost up when the original attic has never been cleaned or when we have to remove rodent-contaminated material before blowing new insulation.
Which is better for Lawndale attics, cellulose or fiberglass?
Cellulose holds up better in damp conditions and fills tight framing bays around old ducting. Fiberglass costs slightly less and resists moisture longer. Both work when installed at the right density for this climate. Call (866) 271-1602 and we will tell you which fits your attic after looking at it.
Can you blow insulation into a Lawndale attic without removing the old material?
Usually yes, if the old material is dry and not full of rodent debris. We remove it only when it is wet or contaminated. A quick attic inspection determines the right call.
Brands We Service in Lawndale
We stock Rockwool mineral wool for fire resistance and sound dampening, GreenFiber cellulose for recycled-content attic work, and spray foam from Icynene and Demilec for Lawndale’s damp wall cavities. Our brands page lists what we carry and why each earns its place.

FAQs About Insulation Company in Lawndale
Most retrofit insulation work in Lawndale does not require a permit. A permit can come into play if the job includes structural changes like adding framing or relocating walls. We handle that call based on the specific scope.
We schedule Lawndale estimates within a few days in most cases, and attic blow-in work usually starts the same week. Full removal and air-sealing jobs can take longer depending on the size of the house and what we find.

What Lawndale Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Michelle Bennett"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."
— Sarah Fletcher"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."
— Holly Mercer
