Insulation Company in Long Beach, CA
Blown in insulation solves the most common comfort problem we see across Long Beach: homes built before modern energy codes that leak conditioned air through attics and wall cavities. From 1920s Craftsman bungalows in Belmont Shore to 1960s stucco tract homes near El Dorado Park, older framing and plaster construction leave gaps no batt ever filled. Homestead Insulation Co installs blown in fiberglass and cellulose using three methods across eight manufacturer lines, because one material never fits every house.

Why Long Beach Homes Are Different
Long Beach insulation work splits into two distinct problems. Blocks within a mile or two of the water – Belmont Shore, Naples, the Peninsula, downtown’s east edge – live under a marine layer that keeps attics damp and fasteners corroded for months at a time. Salt air off the harbor settles into crawlspaces and ductwork, so vapor management and air sealing matter more than chasing a higher R-value. Inland, the 90805 and 90808 corridors bake under real summer heat, and sun-blasted attics push temperatures past 140 degrees, radiating into bedrooms below.
The housing stock runs equally broad. Coastal neighborhoods hold 1920s-40s Spanish Colonial and Craftsman bungalows, many with plaster-over-wood walls and no insulation in the original cavities. Inland Long Beach shifts to 1950s-70s stucco tract homes and mid-century apartment blocks with low-slope roofs and shallow attics. Stucco exteriors and pier-and-beam foundations mean most retrofits are blow-in and attic-focused rather than simple batt installs. A tight-cavity bungalow in the Peninsula plays out nothing like a sun-baked stucco box near Lakewood.
Our Main Long Beach Services
Long Beach homeowners call us most about two services: attic insulation for coastal damp and inland heat, and spray foam for the tight-cavity retrofits that older bungalows demand. Both start with a diagnosis of what the house actually needs.
Attic Insulation in Long Beach
Attic work in Long Beach means managing two extremes. Coastal attics in 90814 and 90803 hold moisture from fog and salt air, so we check ventilation and fastener condition before adding material. Inland attics in 90805 and 90808 run hot enough to cook stored boxes, so radiant-barrier and blown-in depth take priority. We inspect the existing insulation, identify air leaks around can lights and plumbing chases, then prescribe the right material and depth. Learn more about Attic Insulation in Long Beach.

Spray Foam Insulation in Long Beach
Spray foam fits Long Beach’s older coastal housing stock, where framing cavities are irregular and plaster walls leave no room for batts. Closed-cell foam air-seals and insulates in one pass, which matters in tight-cavity bungalows near the water where damp air infiltrates through gaps. It also adds structural rigidity to older framing, something homeowners in Naples and Belmont Shore ask about. Open-cell works well for sound control in mid-century apartment conversions.

Blown In Insulation in Long Beach
Blown in insulation is the workhorse retrofit for Long Beach’s older housing stock. Coastal bungalows from the 1920s and 1930s often have zero insulation in wall cavities and a thin layer of settled material in the attic. Inland 1960s tract homes start with fiberglass batts that have compressed and failed. Blown in cellulose or fiberglass fills irregular cavities and reaches spots batts can’t, without tearing open original plaster. We install Blown In Insulation using GreenFiber cellulose and Owens Corning fiberglass, matched to what the house actually needs.
Loose Fill Insulation
Signs you need it
Rooms that run five to eight degrees warmer than the rest of the house, especially upstairs bedrooms in 90805 and 90808, point to settled or missing loose fill in the attic.
What it costs in Long Beach
Blown in loose fill for a typical Long Beach attic runs $1,800 to $3,400, depending on R-value target and attic accessibility.
How we do it
We air-seal the attic floor first, then blow loose fill to a consistent depth across the entire plane, fluffing as we go to hit the specified R-value without gaps.
Blown In Attic Insulation
Signs you need it
An attic that’s under 6 inches of existing material, or any attic above a room that never holds temperature, is a candidate for blown in attic insulation.
What it costs in Long Beach
Blown in attic insulation for a standard Long Beach attic runs $1,500 to $3,000 for cellulose or fiberglass to R-38, before any air-sealing work.
How we do it
We map the attic, air-seal around can lights and plumbing vents, mark depth gauges on the trusses, then blow the material evenly from the farthest corner back to the access hatch.
Blown In Cellulose Insulation
Signs you need it
Older coastal homes in 90814 with plaster walls and no wall insulation are prime candidates for dense-packed blown in cellulose, which fills cavities without gutting the plaster.
What it costs in Long Beach
Dense-pack blown in cellulose in Long Beach runs $2,800 to $5,200 for exterior walls in a typical bungalow, depending on cavity depth and access.
How we do it
We drill small access holes into each stud bay, then dense-pack GreenFiber cellulose at pressure until the cavity reads full, leaving the original plaster intact.
Blown In Fiberglass Insulation
Signs you need it
Attics where moisture is not a concern but existing material has compressed, especially inland homes in 90808, respond well to blown in fiberglass’s resistance to settling.
What it costs in Long Beach
Blown in fiberglass runs $1,700 to $3,200 for a standard Long Beach attic to R-38, depending on removal of old material.
How we do it
We remove or level the existing material, install depth markers, and blow Owens Corning fiberglass to the specified R-value, checking density as we move.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Blown in attic insulation to R-38 | $1,500 – $3,000 |
| Dense-pack wall insulation | $2,800 – $5,200 |
| Loose fill for tight-cavity retrofits | $1,800 – $3,400 |
How long does blown in insulation last in Long Beach?
Cellulose and fiberglass both hold R-value for 20 to 30 years in a dry, ventilated attic. Coastal damp in 90814 can shorten that if leaks go unaddressed, so we check ventilation before blowing. Call (844) 820-1136 for an attic assessment.
Can you blow insulation into existing walls without removing plaster?
Yes. We drill small access holes and dense-pack from outside or inside, then patch and touch up. It’s the standard method for 1920s bungalows in Belmont Shore. Call (844) 820-1136 to see if your walls qualify.

What Long Beach Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Alejandro Torres"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."
— Brandon Park"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
