Insulation Company in Long Beach, CA
Blown in insulation is the most common retrofit we install in Long Beach, and for good reason: most homes here were built before 1970, and many still have whatever thin, settled material the original builder put in. Long Beach’s marine layer changes the equation, though. Fiberglass batts that would hold up fine in Fontana get damp and compressed here, especially in the fog belt from Belmont Shore up through North Long Beach. We approach every Long Beach job as a moisture-management project first and an R-value project second. If you’re researching insulation for a home in the 90810 through 90815 ZIP codes, call us at (866) 271-1602 and we’ll help you sort through what your house actually needs.
Why Long Beach Homes Are Different
Long Beach sits in a coastal marine-layer zone with mild, damp winters and cool, foggy summers. The critical load here isn’t extreme heat or freezing cold, it’s condensation control and air sealing. Fog-heavy mornings in 90803 and 90804 push moisture into attics and crawlspaces year-round. Attic insulation that gets damp loses most of its insulating value, and in older homes that moisture also feeds mold and dry rot in roof decking.
The housing stock compounds the problem. Belmont Shore and Alamitos Beach are full of 1920s and 1930s wood-frame bungalows and stucco duplexes with original ventilation gaps and salt-laden onshore air. In those homes, attic batts are frequently found damp and compressed against the roof deck, which means a simple R-value top-up fails unless a vapor retarder and added soffit venting go in first. Move north to the 90805, 90806, and 90808 tracts and you’re dealing with 1950s and 1960s low-pitch tract homes, many with original attic insulation, knob-and-tube wiring, and unvented knee-wall or raised-floor cavities that complicate any retrofit. None of this is insurmountable, but it means Long Beach jobs reward contractors who know the local building stock, not crews running a generic playbook.
Our Main Long Beach Services
Most Long Beach homeowners call us about one of two things: attics that are under-insulated or air-sealing gaps that let marine air move through the house year-round. Here’s what each involves in this city.
Attic Insulation in Long Beach
Attic work in Long Beach often starts with an inspection that finds moisture damage, compressed batts, or insulation that never met code in the first place. In 1920s and 1930s homes near the coast, we typically need to address ventilation and vapor control before adding insulation, otherwise the new material will fail the same way the old stuff did. In post-war tract homes across 90805 and 90808, we more often find thin fiberglass batts that settled to R-11 or worse and left rooms under roof baking in the afternoon sun. Read our full breakdown at Attic Insulation in Long Beach.
Spray Foam Insulation in Long Beach
Spray foam earns its keep in Long Beach when air sealing is the priority, which is most of the time in this climate. Marine air moves through rim joists, top plates, and old can light housings, and that air movement carries moisture. Closed-cell foam seals those gaps and acts as its own vapor retarder, which is exactly what damp coastal homes need. It’s also our standard recommendation for raised-floor cavities and knee walls where batts sag or get rodent-chewed. Details on Spray Foam Insulation in Long Beach.

Blown In Insulation in Long Beach
Blown in insulation is the workhorse material for Long Beach’s older housing stock. In pre-war bungalows and post-war tract homes alike, blown-in cellulose or fiberglass can reach the places batts can’t: sloped ceilings, enclosed wall cavities, finished attics, and around obstructions like knob-and-tube wiring. The marine layer means we pay close attention to where moisture is coming from before we add material, because blowing insulation into a damp cavity just hides the problem behind a wall. Our Blown In Insulation service covers everything from open attics to dense-pack wall retrofits, and we match the material (cellulose versus fiberglass) to the specific cavity and moisture conditions in your house.
Cellulose Insulation
Signs you need it
You notice drafts in older walls, attic insulation that’s settled well below the top of the joists, or rooms that overheat in summer even with the AC running.
What it costs in Long Beach
Blown-in cellulose for an attic typically runs $1.50 to $3.10 per square foot installed, while dense-pack wall retrofits run $2.20 to $4.40 per square foot depending on access and prep work.
How we do it
We air-seal the attic floor first, then blow cellulose to the specified depth using a two-person crew, one running the hose and one managing the machine and checking density with a depth gauge.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old, compressed fiberglass batts that test at R-11 or worse, or you want a lighter-weight loose fill that maintains loft and won’t settle as much as older cellulose.
What it costs in Long Beach
Blown-in fiberglass typically runs $1.20 to $2.80 per square foot installed, with wall cavities on the upper end of that range due to access and prep.
How we do it
We remove or leave the existing material depending on its condition, air-seal all penetrations, then blow fiberglass to the depth that hits your R-value target, verifying depth at multiple points across the attic.
Loose Fill Insulation
Signs you need it
You have a low-pitch roof, tight attic access, or an older home where batts can’t be laid evenly without leaving gaps and voids.
What it costs in Long Beach
Loose fill projects in Long Beach typically match the blown-in ranges: $1.50 to $3.10 per square foot for cellulose and $1.20 to $2.80 for fiberglass, with dense-pack wall work at $2.20 to $4.40.
How we do it
We evaluate the cavity or attic for moisture and ventilation first, then blow loose fill at the correct density to prevent future settling, checking depth against the target R-value before we finish.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Blown-in fiberglass (attic) | $1.20 – $2.80 per sq ft installed |
| Blown-in cellulose (attic) | $1.50 – $3.10 per sq ft installed |
| Dense-pack wall retrofit (either material) | $2.20 – $4.40 per sq ft installed |
How long does blown in insulation last in Long Beach’s damp climate?
Blown-in fiberglass can last 80 to 100 years if it stays dry; cellulose typically 20 to 30 years before significant settling. The marine layer is the wildcard. Address attic ventilation and roof deck moisture before we blow anything in, and the material will hold its R-value. Call (866) 271-1602 for an assessment of what your attic can support.
Can you blow insulation into existing walls without tearing them open?
Yes. We drill small access holes from the exterior or interior, dense-pack the cavity, and patch the holes. Long Beach’s stucco-duplex stock makes exterior drilling common; wood-frame bungalows often go from inside. Call (866) 271-1602 for a wall-by-wall plan and a firm quote.

What Long Beach 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."
— 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"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Nadia Aziz
