Insulation Company in Long Beach, CA
Blown in insulation solves the most common comfort problem in Long Beach homes: walls and attics that were never filled when the house was built, or that have settled and thinned over decades of coastal humidity. Most of the housing stock in neighborhoods like Rose Park and Belmont Shore dates to the 1920s through 1940s, and a surprising number of those homes still have empty wall cavities or a few inches of tired attic fiber. Brea Insulation specializes in retrofit blown in insulation – drilling small access points, filling cavities densely, and sealing the envelope so the marine layer stops working its way into your living space.

Why Long Beach Homes Are Different
Long Beach sits directly on the Pacific, and the marine layer that rolls in most evenings isn’t just a temperature issue – it’s a moisture delivery system. Homes here live with relative humidity that routinely climbs past 70%, and that changes what insulation should do. You’re not fighting a hot attic in August the way a homeowner in the Inland Empire is. You’re fighting condensation, trapped moisture, corroded facings, and insulation that quietly loses its R-value because it stays damp for weeks at a time.
The housing stock compounds the problem. In Belmont Shore, Bluff Park, and Rose Park, we work on 1920s and 1930s bungalows and Spanish Revival stucco homes with unvented attics, minimal wall cavities, and – in many cases – original knob-and-tube wiring still running through the framing. In the 90804 and 90806 ZIP codes, the Craftsman-era homes often have no wall insulation at all. Even the 1950s and 1960s tract homes near the Lakewood border were built when fiberglass batts were installed loosely, if they were installed at all. Add decades of salt air working on foil and paper facings, and you get a housing stock that needs a different approach than inland LA homes.
Long Beach also has a specific code reality: any insulation work that touches walls or attics may require a permit through the City of Long Beach’s Building and Safety Bureau, and older homes with knob-and-tube wiring need a clearance inspection before we can blow insulation around those conductors. We handle that conversation as part of the job, not as a surprise halfway through.
Our Main Long Beach Services
Long Beach homeowners call us most about two problems: attics that need a real air seal and insulation top-up, and walls or rim joists that need the air-sealing power of spray foam. Here’s how each works in this city.
Attic Insulation in Long Beach
Attic work in Long Beach is less about piling on R-value and more about getting the existing attic to behave in a humid climate. We regularly find attics in Bluff Park and Rose Park that were insulated with thin fiberglass and ventilated poorly, so the marine layer moves through the attic all year, moistening the insulation and the framing underneath it. The job involves air sealing penetrations – recessed lights, plumbing vents, chimney chases – then installing a properly specified insulation layer that won’t hold moisture. In salt-heavy neighborhoods near the bluff, we’re also replacing corroded facings and checking for decking damage before the new material goes in. Read more on our Attic Insulation in Long Beach page.
Spray Foam Insulation in Long Beach
Spray foam is the strongest tool for coastal homes because it insulates and air seals in a single pass. In Long Beach, that matters in wall cavities that let the marine layer travel straight into the house – we find this all the time on pre-war bungalows where window air conditioner sleeves were cut through exterior walls and never sealed properly. Spray foam locks those penetrations down and fills irregular joist bays that batts can’t. For crawl spaces under the older pier-and-beam homes in Belmont Shore, closed-cell foam also creates a moisture barrier that fiberglass simply can’t match. See full details on our Spray Foam Insulation in Long Beach page.

Blown In Insulation in Long Beach
Blown in insulation is the most practical retrofit method for Long Beach’s older housing stock because it goes into finished walls and attics without tearing out drywall or plaster. In neighborhoods like Rose Park and the Craftsman streets of 90806, we fill wall cavities that have been empty since the 1920s, using cellulose or fiberglass blown to a dense, stable pack. The material we choose depends on the cavity depth, the presence of old wiring, and the moisture exposure in that specific wall – and we carry the full range so we can match material to condition. This is the work we do most often in Long Beach, and it’s where the Blown In Insulation method earns its keep.
Blown In Attic Insulation
Signs you need it
Your attic insulation measures under 6 inches deep, or you feel heat gain in top-floor rooms by mid-morning on clear days.
What it costs in Long Beach
Blown in attic insulation in Long Beach typically runs $2.00 to $5.50 per square foot, depending on target R-value and whether air sealing is included.
How we do it
We air seal the attic floor, install insulation baffles, then blow loose fill to the specified depth and density across the entire attic plane.
Blown In Cellulose Insulation
Signs you need it
You want a recycled-content option that fills wall cavities densely and resists air movement through old plaster and lath assemblies.
What it costs in Long Beach
Blown in cellulose insulation in Long Beach runs $1.50 to $4.00 per square foot for walls and $2.00 to $5.50 per square foot for attics.
How we do it
We drill access holes, blow GreenFiber or similar cellulose to a dense pack, then patch and texture-match the openings.
Loose Fill Insulation
Signs you need it
You have an open attic with shallow or settled fiberglass, or an accessible floor cavity that’s lost its thermal barrier.
What it costs in Long Beach
Loose fill insulation in Long Beach runs $2.00 to $5.50 per square foot, with remediation or old-insulation removal billed separately if needed.
How we do it
We remove any damaged material, prep the cavity, and blow loose fill to the R-value suited for Long Beach’s marine climate.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Blown in attic insulation | $2.00 – $5.50 per sq ft |
| Blown in wall insulation | $1.50 – $4.00 per sq ft |
| Blown in cellulose (walls) | $1.50 – $4.00 per sq ft |
Is blown in insulation worth it for an older Long Beach home?
Yes, and it’s usually the highest-impact retrofit available. Filling empty wall cavities on a 1920s bungalow can cut air leakage dramatically, and the material cost is lower than tearing out walls. Call (866) 858-4033 for a wall cavity assessment.
Can you blow insulation into walls that have knob-and-tube wiring?
No, not until the wiring is cleared by a licensed electrician. We flag knob-and-tube during our initial walkthrough and help coordinate the inspection before any insulation touches the cavity.
Brands We Service in Long Beach
We run an eight-brand material bench so the product fits the job, not the other way around. In Long Beach, that means Icynene and Demilec spray foam for air-sealing coastal walls, GreenFiber cellulose for dense-pack retrofits in older homes, and Owens Corning fiberglass for standard attic top-ups. Most materials are staged locally, so scheduling is measured in days, not weeks. See the full lineup on our brands page.
