Insulation Company in Long Beach, CA
Blown in insulation solves a problem Long Beach homeowners know too well: walls and attics that were never filled when the house went up. Much of the housing stock here dates to the 1920s through 1960s, and a lot of those cavities are empty or settled to almost nothing. Meadow Insulation specializes in retrofitting older Long Beach homes with dense-packed cellulose and blown fiberglass, working around stucco exteriors and tight lot lines that make other methods impractical. Call (833) 589-8312 for a free estimate and we’ll tell you exactly what’s in your walls today.
Why Long Beach Homes Are Different
Long Beach sits right on the coast, so the dominant insulation problem here isn’t heating-degree-days like inland LA. It’s salt-laden marine air and near-constant humidity driving condensation, corrosion, and mold risk inside walls and under floors. The persistent onshore marine layer off the Port of Long Beach keeps wall cavities and crawlspaces damp, and our crews routinely find corroded fasteners, rusted ducts, and mold at the cool north- and west-facing wall interiors of older bungalows. Insulation jobs in Long Beach often start with moisture remediation rather than just adding R-value.
The housing stock compounds the issue. ZIP codes like 90802, 90803, and 90804 are full of 1920s-40s Spanish-Revival and Craftsman bungalows with pier-and-beam floors and uninsulated knob-and-tube-era wall cavities. In 90805 and 90806, 1950s-60s tract homes and apartment buildings have their own challenges: thin wall assemblies, settled attic insulation, and dense multifamily layouts that leave little room for error. Blown in insulation works especially well here because it fills irregular cavities without tearing open stucco or disturbing original framing.
Our Main Long Beach Services
Most Long Beach homeowners call us about one of two things: an attic that’s bleeding conditioned air, or walls and crawlspaces that need air-sealing against marine moisture. Here’s what each involves locally.
Attic Insulation in Long Beach
Attics in Long Beach run hot and humid even when the outside temperature is mild, and that trapped heat pushes down into living spaces all afternoon. We blow Owens Corning or Johns Manville fiberglass to the correct depth for our coastal climate, but we always check ventilation and vapor control first. A sealed attic without airflow will hold moisture against the roof deck, and salt air accelerates the damage. Attic Insulation in Long Beach covers the full scope, including air-sealing around can lights and penetrations.
Spray Foam Insulation in Long Beach
Closed-cell spray foam is the strongest tool we have against Long Beach’s humidity problem. It acts as its own vapor barrier, which matters when marine fog sits against a crawlspace or rim joist for weeks at a time. We install Icynene and Demilec open- and closed-cell foams, choosing density based on whether the space is vented, unvented, or exposed to salt air. Spray Foam Insulation in Long Beach explains when foam makes sense and what it costs in this market.

Blown In Insulation in Long Beach
Blown in insulation is the most practical retrofit for Long Beach’s older wall cavities. Homes built before the 1960s in neighborhoods like Belmont Heights, Rose Park, and Wrigley often have empty stud bays or loose fill that has compacted into a thin mat at the bottom. Blown in insulation lets us fill those cavities through small access holes, from the exterior when stucco is present or the interior when trim is easy to remove. Because Long Beach’s humidity makes moisture management the real priority, we always pair blown in work with an assessment of vapor barriers, ventilation, and any existing mold or rust damage. For a deeper look at the method, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your walls feel cold to the touch in winter despite the mild Long Beach climate, and your energy bills stay high even when windows are closed.

How we do it
We dense-pack GreenFiber cellulose into wall cavities through small drilled holes, then patch and match the exterior stucco or interior plaster.
Blown In Attic Insulation
Signs you need it
The upstairs rooms run five to eight degrees warmer than downstairs every afternoon, even with the windows open to the ocean breeze.
What it costs in Long Beach
Blown in attic insulation in Long Beach typically costs $1,500 to $3,000 for a 1,000 to 1,500 square foot attic, depending on depth and prep work.
How we do it
We remove any moldy or compressed old material, air-seal the attic floor penetrations, and blow Owens Corning fiberglass to the R-value suited for a coastal attic.
Loose Fill Insulation
Signs you need it
Your attic has visible low spots or bare patches, and the loose fill that’s there settles an inch or more every couple of years.
What it costs in Long Beach
Loose fill insulation in Long Beach runs $0.90 to $1.80 per square foot installed, which typically lands between $1,200 and $2,700 for most attics.
How we do it
We blow loose fill to an even depth across the attic floor, maintaining clearance around recessed lights and eave vents so airflow stays intact.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Blown in cellulose (walls) | $1.50 – $3.00 per sq ft |
| Blown in fiberglass (attic) | $0.90 – $1.80 per sq ft |

How long does blown in insulation last in Long Beach’s humid climate?
Cellulose and fiberglass can last 20 to 30 years, but Long Beach’s humidity shortens that if air leaks keep drawing moist air into cavities. Properly installed and sealed, it holds up. Call (833) 589-8312 for an inspection.
Can you blow insulation into walls with old knob-and-tube wiring?
No. Blown in insulation cannot be installed over live knob-and-tube wiring. We’ll check for it during the estimate and recommend the right alternative. Call (833) 589-8312 to schedule a look.

— Neil Mercer"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."
— Diego Flores"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
