Insulation Company in Long Beach, CA
Blown in insulation is the most practical retrofit for most Long Beach homes, especially the pre-war bungalows and 1950s tract houses that make up so much of 90813 and 90814. What makes our work different here isn’t just adding R-value. It’s managing the coastal marine layer humidity that creeps through vented crawlspaces and uninsulated walls, condensing on cool surfaces and quietly rotting framing. Snug Insulation has served Long Beach since 2016, and we match the material to the house: cellulose for open attics, fiberglass for tight budgets, and a vapor strategy that respects the salt air.

Why Long Beach Homes Are Different
Long Beach sits inside a coastal marine layer zone, which flips the usual insulation conversation on its head. The problem here is not brutal winter cold. It’s year-round damp air, mild temperatures, and salt-laden onshore flow that corrodes foil facings and fasteners within a few miles of the water in 90802 and 90803. When we open up an attic in Naples or Belmont Shore, we’re usually looking at insulation that has been quietly absorbing moisture for years, losing its R-value and holding water against the framing.
The housing stock compounds the issue. The older core, codes 90802 through 90806, is dense with 1920s and 30s bungalows and craftsman-style houses built with balloon framing and little or no original wall insulation. Many of those homes had nothing in the attic beyond a thin layer of dust and maybe some newspaper from the Hoover administration. The post-war tracts in 90805 and 90808 are different: stucco-clad, pier-and-beam raised floors, shallow attics, and vented crawlspaces that pull in marine-layer air every afternoon. And a large share of Long Beach’s housing stock is rental or multi-unit, which means we often coordinate with property owners and tenants on access and scheduling before any material goes in.
In the older coastal bungalows, we routinely find uninsulated balloon-frame walls where the marine-layer humidity condenses on cool stud surfaces inside the wall cavities. The fix is often air sealing and a vapor strategy before adding batt or blowing insulation into the attic. Simply blowing more cellulose into a damp, unsealed attic in 90803 without addressing the moisture path is a waste of material.
Our Main Long Beach Services
Long Beach homeowners call us most often about two jobs: attic insulation and spray foam. Both have their own dedicated Long Beach pages with local pricing and specifics, but here’s the short version.
Attic Insulation in Long Beach
Most pre-1980 Long Beach homes are under-insulated in the attic, and in our marine layer, that means heat gain in summer and damp, heavy air in winter. We inspect the existing insulation, check for moisture damage and rodent activity, seal the bypasses, and install the right material for the house, whether that’s blown fiberglass, cellulose, or batts. Attic Insulation in Long Beach covers the full local breakdown.
Spray Foam Insulation in Long Beach
For homes within a mile or two of the water in 90802 and 90803, open-cell spray foam can serve as an air barrier and a vapor-managing layer in one pass. We use Icynene and Demilec systems for these jobs, which matters when the salt air punishes cheap materials. Spray Foam Insulation in Long Beach has the full details on closed-cell vs. open-cell here.

Blown In Insulation in Long Beach
Blown in insulation is the fastest way to bring a Long Beach attic up to modern thermal performance without tearing out drywall or rebuilding the roof deck. In a 1940s bungalow in 90813 with a shallow attic and no existing insulation, we can usually complete the job in half a day, and the comfort difference is immediate. We also use blown in as a retrofit for walls in select Long Beach homes, drilling small access holes from the exterior and dense-packing the cavities. Read more on our full Blown In Insulation service page. The key in Long Beach is pairing the blow with air sealing and, near the coast, a vapor strategy that acknowledges the marine layer. Insulation that stays dry performs. Insulation that absorbs Long Beach humidity does not.
Cellulose Insulation
Signs you need it
Your attic has old, settled fiberglass that measures under six inches deep, or the upstairs rooms swing hot and cold while the bills climb.
What it costs in Long Beach
Blown-in cellulose for a typical 1,000-square-foot Long Beach attic runs $1.50 to $3.50 per square foot including installation.
How we do it
We air seal the bypasses, protect the soffit vents, and dense-pack or loose-fill the cavity to the specified R-value using GreenFiber recycled-content cellulose.
Blown In Attic Insulation
Signs you need it
The attic floor has visible joists with thin or missing insulation between them, or the upstairs feels like a sauna by 4 p.m. in a 90815 summer.
What it costs in Long Beach
Blown-in attic insulation across Long Beach typically lands between $1.50 and $4.00 per square foot depending on the existing depth and access.
How we do it
We remove or supplement the old material as needed, air seal, and blow new insulation to the correct depth with a calibrated machine, then level it for consistent coverage.
Blown In Fiberglass Insulation
Signs you need it
The attic insulation is dusty, matted, or rodent-damaged, and you want a clean, moisture-resistant loose-fill option.
What it costs in Long Beach
Blown-in fiberglass in Long Beach attics runs $1.50 to $2.80 per square foot installed, slightly below cellulose on many jobs.
How we do it
We prep the attic, air seal, and blow loose-fill fiberglass to the target R-value, checking depth with a gauge as we go so coverage is consistent.
Loose Fill Insulation
Signs you need it
You have an open attic with easy access where a loose-fill product, either cellulose or fiberglass, is the fastest and most cost-effective retrof
What it costs in Long Beach
Loose fill insulation in Long Beach attics falls in the same $1.50 to $4.00 per square foot range based on material, depth, and attic accessibility.

Can you blow insulation into existing walls in Long Beach?
Yes, we dense-pack cellulose into closed wall cavities from the exterior, which works well for the uninsulated 1920s and 30s bungalows common in 90813 and 90806. This requires drilling small access holes and is done from outside where possible.
How long does blown in insulation take in Long Beach?
Most Long Beach attics are insulated in four to six hours, from setup to cleanup. Wall dense-packing typically takes a full day depending on access and the condition of the exterior siding.
