Insulation Company in Long Beach, CA
Blown in insulation solves the problem most Long Beach homes actually have: walls and attics that were never insulated when they were built, or insulation that’s settled and useless against the marine layer. The pre-war bungalows in Belmont Shore and the 1950s stucco tracts in Los Altos weren’t designed for modern Title 24 compliance, and they certainly weren’t designed to keep damp ocean air from creeping through every unsealed gap. North Tustin Insulation has served Long Beach since 2011, and we carry the materials that work in a coastal cooling climate: GreenFiber cellulose, Owens Corning fiberglass, and open-cell spray foam that stops moisture before it becomes mold. Call (877) 265-5712 for an honest assessment of what your walls and attic actually need.
Why Long Beach Homes Are Different
Long Beach insulates for mild, coastal-cool weather with no real heating or cooling load, so the fight here is condensation, marine air, and airborne noise rather than freezing pipes or brutal heat. The dense mix of pre-war bungalows and post-war tract homes just blocks from the ocean means a huge share of the work is moisture control and sound isolation, not R-value chasing. We regularly open walls in 90803 homes built in the 1930s and find no insulation at all, just lathe and plaster and a gap where the fog seeps through.
The bungalow blocks near the beach in 90802 and 90803 sit in thick marine fog half the year. An improperly installed vapor barrier or an unsealed crawlspace becomes a hidden mold problem within two seasons. The thick walls of these old cottages are as much about muting the noise of a busy beach neighborhood as they are about energy savings. Move inland to 90808 and you get 1960s stucco tract homes with thin fiberglass batts that have compressed to nothing over fifty years. Both jobs require completely different materials and methods, and that’s exactly why we carry multiple insulation types under one roof.
California’s Title 24 cooling climate rules apply throughout Long Beach, which changes how we spec insulation for attics and walls in every ZIP from 90810 to 90815. Marine-layer dampness that never exists ten miles inland shapes every recommendation we make.
Our Main Long Beach Services
Two services get most of the calls from Long Beach homeowners: attic insulation for the hot, unconditioned spaces above the ceiling, and spray foam for sealing the gaps that let marine air inside. Here’s what each one involves locally.
Attic Insulation in Long Beach
Most Long Beach attics we inspect have either no insulation or a thin layer of 1970s fiberglass that’s compressed and damp from decades of coastal air. We remove what’s there, air-seal every penetration, and install the right material for the home’s era: blown-in cellulose for old bungalow framing, fiberglass batts for standard rafter spacing, or spray foam for ventless attics in multifamily units. Title 24 compliance matters here because the building department actually checks. See the full scope on our Attic Insulation in Long Beach page.
Spray Foam Insulation in Long Beach
Spray foam earns its cost in Long Beach when it solves condensation problems that fiberglass never touches. Closed-cell foam on rim joists and crawlspace walls blocks the damp marine air that rots floor framing in beach-adjacent homes. Open-cell foam in attic rooflines quiets the neighborhood noise that travels straight through old single-pane windows and thin ceilings. We install Icynene and Demilec systems, both of which we carry because different coastal jobs need different foam densities. Read the full breakdown on our Spray Foam Insulation in Long Beach page.

Blown In Insulation in Long Beach
Blown in insulation is the most common retrofit we perform in Long Beach because it’s the only practical way to add insulation to closed walls and cramped attic cavities without tearing the house apart. For pre-war bungalows in 90802 and 90803 with empty wall bays, blown-in cellulose or fiberglass fills the cavity through small access holes and immediately cuts both air movement and street noise. For 1950s and 60s tract homes in 90808 and 90815, blowing insulation over settled attic batts restores the thermal barrier and helps the home meet Title 24’s cooling climate minimums. This is the flagship service at North Tustin Insulation, and you can read the full method and material details on our Blown In Insulation hub page.
The thing about blown in insulation near the coast is that material choice matters more than most contractors admit. GreenFiber cellulose holds up better in Long Beach’s damp air than loose fiberglass does, because cellulose buffers moisture while fiberglass just lets it pass through to the framing. We see this difference in homes within six blocks of the beach versus homes up by the Traffic Circle. Same service, different material, and that’s the conversation we have at every estimate.
Cellulose Insulation
Signs you need it
Rooms that stay cold and damp even with no AC running, walls that feel hollow when you knock, and an energy bill that climbs every year in spring and fall when the fog sets in.
What it costs in Long Beach
Blown-in cellulose for attics in Long Beach typically runs $1,500 to $3,800 depending on square footage and existing conditions.
How we do it
We drill access holes into each wall cavity or drop the material across the attic floor, then blow GreenFiber cellulose to the specified density and patch every opening clean.
Blown In Attic Insulation
Signs you need it
The upstairs rooms heat up in the afternoon sun even when the air is cool, the existing attic insulation looks thin or matted, and you can feel temperature differences between rooms on the same floor.
What it costs in Long Beach
Attic blow-in projects in Long Beach generally range from $1,500 to $4,300 including removal of failed material and air sealing.
How we do it
We clear the attic of old, compressed insulation, seal the top plates and penetrations, then blow new material to the R-value the home’s framing and Title 24 require.
Blown In Cellulose Insulation
Signs you need it
Your home is pre-1980 with empty or partially filled wall cavities, drafts move through outlets and baseboards, and neighborhood noise comes straight through the exterior walls.
What it costs in Long Beach
Dense-pack cellulose wall retrofits in Long Beach typically run $2,500 to $6,500 depending on wall count and access difficulty.
How we do it
We drill small access points from the interior or exterior, dense-pack GreenFiber cellulose into each stud bay at the correct pressure, then restore the surfaces to a patch-ready finish.
Blown In Fiberglass Insulation
Signs you need it
Open attic spaces with accessible rafter bays where the old fiberglass has settled below the top of the joists, leaving bare spots that show heat movement through the ceiling.
What it costs in Long Beach
Blown-in fiberglass for Long Beach attics generally falls between $1,200 and $3,500 for a typical 1,000-1,500 square foot attic.
How we do it
We blow Owens Corning loose-fill fiberglass evenly across the attic floor to the target depth, keeping the material away from soffit vents to preserve airflow.
What Blown In Insulation Costs in Long Beach
| Item | Typical range in Long Beach |
|---|---|
| Cellulose attic blow-in | $1,500 – $3,800 |
| Blown-in fiberglass attic | $1,200 – $3,500 |
| Dense-pack cellulose walls | $2,500 – $6,500 |
Is blown in insulation worth it in Long Beach if I barely run AC?
Yes, because the payoff here is moisture control and noise reduction, not just HVAC savings. Sealing and insulating walls stops marine air from condensing inside your framing, which prevents mold and keeps street noise out of bedrooms.
Can you blow insulation into walls that already have some insulation?
Sometimes. If the existing material has settled or left voids, we can dense-pack additional cellulose into the same cavities to restore coverage. We assess each wall with a scope before recommending anything. Call (877) 265-5712 for a free estimate.

FAQs About Insulation Company in Long Beach
Most Long Beach homeowners get an estimate within 2 to 3 business days of calling. We cluster estimates by ZIP so we’re not crisscrossing the city, and we carry moisture meters and inspection scopes on every visit. Call (877) 265-5712 to get on the schedule.
Most insulation retrofits in Long Beach don’t require a permit, but Title 24 compliance still applies, and any project that changes the building envelope may trigger inspection requirements. We handle the paperwork when it’s needed and make sure the installed R-values match what the building department expects to see.
Because a 1930s beach bungalow in 90802 has empty wall cavities, single-pane windows, and constant marine air, while a 1960s stucco tract home in 90808 has settled batts and an open attic. The material and the method change with the home’s era and distance from the water. That’s why we carry eight brands instead of pushing one product on every house.
