Insulation Company in Long Beach, CA
Blown in insulation solves a problem most Long Beach homeowners don’t know they have until the first muggy summer night or the first winter heating bill that makes no sense. The city’s 1920s bungalows in Bluff Park and the 1960s tract homes across the east side were built when energy was cheap and insulation was an afterthought. What’s there now has settled, compacted, or was never sufficient to begin with. Hollywood Insulation Co has served Long Beach since 2018, installing blown in insulation that accounts for the marine layer, the salt air, and the way older wood-frame homes actually behave here.

Why Long Beach Homes Are Different
Long Beach sits directly in the coastal marine layer zone, and that changes everything about how insulation should be specified. The persistent June Gloom and damp salt air push moisture into walls and attics in ways that inland cities like Lakewood or Carson simply don’t experience. In neighborhoods like Belmont Shore and Rose Park, we regularly find fiberglass batts that look intact but have been quietly absorbing fog-driven humidity for decades, losing R-value and creating the conditions where mold takes hold. The insulation challenge here isn’t extreme heat or cold. It’s moisture control, vapor management, and ventilation done correctly.
The housing stock compounds the problem. Those charming 1920s and 1930s California bungalows and Spanish Revival homes were built with little or no wall insulation, and what went into the attics has long since settled below the top plates. The mid-century tracts across the north and east ZIP codes are no better, with thin original batts that never met modern energy codes. Multifamily buildings add another layer: shared attic cavities and party walls where thermal and sound isolation both matter. Homeowners assumed for years that mild coastal weather meant insulation didn’t matter here. That assumption is exactly why so many Long Beach homes are uncomfortable and expensive to condition.
Our Main Long Beach Services
Two services account for most of the calls we take from Long Beach homeowners: attic insulation and spray foam insulation. Here’s what each one involves in this city’s housing stock.
Attic Insulation in Long Beach
Most Long Beach attics we inspect have settled fiberglass batts from the original build or the last remodel, often compressed under storage boxes and covered in decades of dust. Air leaks around recessed lights, plumbing chases, and the attic hatch go untreated, which means the HVAC system works harder than it should. We remove or top up what’s there, air-seal the critical gaps, and bring the attic up to a level that actually holds conditioned air where it belongs. In coastal bungalows especially, we check for the unvented foil-faced insulation jammed against the roof deck that traps June Gloom moisture, because the fix starts with ventilation, not more material. Attic Insulation in Long Beach covers the full scope of this work.

Spray Foam Insulation in Long Beach
Spray foam does what batts and loose fill cannot: it air-seals while it insulates. That matters in Long Beach because the marine layer drives damp air into every crack and gap in the building envelope. Closed-cell foam, applied by a crew that knows how to handle coastal moisture conditions, creates a thermal and air barrier that also resists the salt-laden humidity that corrodes and degrades other materials over time. We install both Icynene and Demilec systems, matching open-cell or closed-cell to the specific cavity and the specific problem, whether that’s an uninsulated wall in a Belmont Shore bungalow or a multifamily attic with shared fire-rated assemblies. Spray Foam Insulation in Long Beach explains the two systems in detail.

Blown In Insulation in Long Beach
Blown in insulation is the most practical retrofit for the majority of Long Beach homes, especially the pre-war bungalows and mid-century tracts where the original attic insulation has settled to nearly nothing. In this city, loose fill has to do two jobs at once: reach target R-value and stay dry in the marine layer, which means the material choice and the ventilation details matter more here than they would inland. We install both cellulose and fiberglass blown in systems, each chosen for the specific attic, the specific home, and the specific moisture profile of the neighborhood. Our Blown In Insulation service covers everything from attic top-ups to full wall cavity retrofits.
Cellulose Insulation
Signs you need it
You can see the tops of your ceiling joists in the attic, rooms feel drafty in winter, or your energy bills creep up every year without a change in usage.
What it costs in Long Beach
Blown in cellulose for a typical Long Beach attic runs $1.20 to $2.50 per square foot installed, depending on depth and access.
How we do it
We air-seal the bypasses first, then blow GreenFiber cellulose to the specified depth using a calibrated machine, checking density as we go.
Blown In Attic Insulation
Signs you need it
Your attic has thin, settled, or compressed original insulation, or rooms on the top floor are consistently hotter than the rest of the house.
What it costs in Long Beach
Blown in attic insulation in Long Beach typically ranges from $1,200 to $3,400 for a full attic job, varying with square footage and target R-value.
How we do it
We measure the existing depth, work out what’s needed to hit the recommended R-value for this climate, then blow loose fill evenly to cover the entire attic floor, keeping soffit vents clear.
Blown In Fiberglass Insulation
Signs you need it
Your insulation has visible gaps, rodent damage, or has been flattened by foot traffic and storage over the years.
What it costs in Long Beach
Blown in fiberglass runs $0.80 to $2.10 per square foot installed in Long Beach, slightly less than cellulose on average.
How we do it
We use CertainTeed loose-fill fiberglass, blown to the specified depth with the same air-sealing and ventilation checks we do on every attic job.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Blown in fiberglass (per sq ft installed) | $0.80 – $2.10 |
| Blown in cellulose (per sq ft installed) | $1.20 – $2.50 |
| Full attic blow-in (typical home) | $1,200 – $3,400 |
How long does blown in insulation last in Long Beach’s humidity?
Cellulose and fiberglass both hold up well here if the attic is properly ventilated. The real risk is moisture trapped by poor ventilation, which degrades any insulation. We address venting on every job.
Is blown in insulation better than batts for older Long Beach homes?
For older attics with irregular joist spacing, settled batts, and lots of penetrations, blown in insulation fills the gaps batts miss. It’s the most complete retrofit for pre-war and mid-century Long Beach homes.
