Insulation Company in Long Beach, CA
Blown in insulation is the retrofit workhorse for Long Beach homes, and for good reason. Most of the city’s housing dates from the 1920s through the 1950s, when insulation was either newspaper, sawdust, or simply not there. Our crews work in attics across 90810, 90813, 90814, and 90815 where the original material is long gone, and the fix that makes the most sense is dense-packed cellulose or loose-fill fiberglass installed through small access points. Add the marine layer that keeps Belmont Shore damp at 7 a.m. three hundred days a year, and the job becomes as much about moisture control as temperature. Call us at (855) 341-7856 and we’ll tell you what’s actually in your attic and what it would take to fix it.
Why Long Beach Homes Are Different
Long Beach sits inside a coastal marine-layer zone, which means cool, damp mornings and air that carries salt from the harbor. Insulation here has to handle moisture as much as heat gain. A product that performs well in inland LA can trap condensation inside a Bluff Park bungalow and grow mold within a couple of marine-layer seasons. We see it regularly: fiberglass batts with rusted staples, paper facing curling away from the studs, and dark staining where warm interior air met a cool exterior wall.
The housing stock compounds the issue. Much of Long Beach is 1920s to 1950s Spanish-style and bungalow construction, stucco over wood frame, with low-pitch attics that were never designed for modern insulation depths. East side neighborhoods from the 1960s and 1970s have their own issues, primarily original batts compressed to half their rated R-value. Older multi-family buildings near downtown and the port are frequently under-insulated or not insulated at all. We also run into knob-and-tube wiring and early romex in the oldest attics, which changes how we approach air sealing and where we place material. None of this is unusual to us. It’s the baseline for working in Long Beach.
Our Main Long Beach Services
Most Long Beach homeowners call us about two things: the attic above them and the walls around them. Here’s how each one works in this city.
Attic Insulation in Long Beach
Your attic is where most Long Beach homes lose conditioned air, and where the marine layer does its worst work. Low-pitch attics with minimal venting trap moisture against the underside of the roof deck, and old insulation sitting below the joist tops means the ceiling below never holds temperature. We inspect the existing venting before we add anything, because adding insulation to a poorly vented Long Beach attic can turn a warm house into a mold farm. For the full breakdown on how we handle attics in this city, including venting corrections and air sealing, see Attic Insulation in Long Beach.
Spray Foam Insulation in Long Beach
Spray foam earns its keep in Long Beach when air sealing matters as much as R-value, which is most of the time near the coast. Open-cell foam on the roofline lets us insulate and seal in one pass, while closed-cell adds structural rigidity to older framing and acts as a vapor retarder where the salt air pushes moisture into building cavities. The catch is application: foam needs clean, dry substrate, and the marine layer means we schedule around dew point. Read the full Long Beach guide here: Spray Foam Insulation in Long Beach.

Blown In Insulation in Long Beach
Blown in insulation solves the problem most Long Beach homes actually have: cavities and attics that were never insulated properly and are nearly impossible to reach with batts. In the city’s 1920s bungalows, we dense-pack cellulose into closed wall cavities without tearing out the stucco. In the 1960s tract houses on the east side, we blow loose-fill fiberglass over compressed original batts to restore thermal performance. Either way, the right material matters less than the right density and coverage, which is why we carry multiple brands including Knauf and GreenFiber and choose based on the cavity and the climate. Here’s the Blown In Insulation work we do most often in Long Beach.
Cellulose Insulation
Signs you need it
Rooms that never hold temperature, dust in the air, or old newspaper and sawdust visible in the attic are all signs your Long Beach home needs cellulose.
What it costs in Long Beach
Blown-in cellulose in Long Beach typically runs $1.10 to $1.80 per square foot installed, depending on depth and access.
How we do it
We run a hose to the attic or wall cavity, dense-pack or loose-fill to the specified R-value, and net or contain the material so it stays put through coastal humidity swings.
Blown In Attic Insulation
Signs you need it
An attic floor with bare spots, batts below the joist tops, or summer heat radiating through the ceiling means blown-in attic insulation is the fix.
What it costs in Long Beach
Blown-in attic insulation in Long Beach typically runs $1.50 to $2.80 per square foot, including prep and air sealing where needed.
How we do it
We seal the attic bypasses first, then blow loose-fill fiberglass or cellulose to R-38 or R-49 across the entire attic floor, keeping the eave vents clear for airflow.
Loose Fill Insulation
Signs you need it
If your attic has old, compressed batts or empty joist bays, loose fill insulation is the fastest way to restore real thermal performance.
What it costs in Long Beach
Loose fill insulation in Long Beach typically ranges from $0.90 to $1.60 per square foot, depending on material and target depth.
How we do it
We blow material across the attic floor in smooth, consistent passes, measuring depth as we go so you get the R-value we quoted, not an approximation.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Cellulose attic insulation (R-38) | $1.10 – $1.80 / sq ft |
| Blown-in fiberglass attic insulation | $0.90 – $1.60 / sq ft |
| Dense-pack wall cavity cellulose | $1.80 – $2.50 / sq ft |
How long does blown in insulation last in Long Beach?
Cellulose and fiberglass both last the life of the home when installed correctly, but Long Beach’s humidity means improper venting can shorten that significantly. We check venting before we blow, and we use materials that resist moisture absorption.
Can you blow insulation into walls without removing stucco?
Yes. We dense-pack cellulose through small holes drilled into the wall cavity, usually from the exterior, then patch the holes to match. It’s a one-day job for most Long Beach homes, and it works well with the city’s stucco-over-wood-frame construction. Call (855) 341-7856 for an exact quote.

We carry Johns Manville, Knauf, and CertainTeed product lines for Long Beach jobs, with Rockwool available when fire resistance or sound attenuation is the priority. Having our brands stocked locally means most blown-in projects in Long Beach start within a week of your call.

Most retrofit insulation work in Long Beach does not require a permit, but some older homes with knob-and-tube wiring may need an electrical inspection before we can insulate around it. We’ll tell you during the estimate if that applies to your house.
Yes, and it’s the bulk of our work here. We’re comfortable with the 1920s stucco bungalows, the 1950s tract houses, and everything in between. We know how to work around original framing, early wiring, and the venting limitations those houses came with. Call (855) 341-7856 for a free estimate.
