Insulation Company in Long Beach, CA
Fountain Valley Insulation installs blown-in insulation, attic insulation, and spray foam for Long Beach homeowners. The work here is shaped by two things: housing stock from the 1910s through the 1970s with tight, awkward attic spaces and stucco-over-wood walls, and a marine climate where trapped moisture causes more problems than heat alone. If your energy bills swing hard between foggy mornings and sunny afternoons, we can tell you which material actually fits your home. Call (833) 390-3099 for a straight answer.
Why Long Beach Homes Are Different
Long Beach sits on coastal marine air, which changes the insulation conversation entirely. In the shoreline flats around 90803 and 90802, the persistent morning marine layer means attics collect condensation that never fully dries. Salt-laden air accelerates rust on decking and fasteners. The fix is never just “add more R-value.” A vapor-impermeable material in the wrong spot can trap that damp air and make the problem worse. Inland ZIP codes like 90805 bake under the same sun that makes attic ventilation and radiant-barrier work essential. The 710 freeway roughly marks the line: west toward the water, moisture management leads the strategy; east toward Lakewood, heat gain and airflow do.
The housing stock adds another layer. Long Beach is full of early-1900s to 1950s bungalows, Spanish Revival, and Craftsman homes. Many were built with balloon-frame construction, stucco over wood, and attic spaces you cannot stand up in. Knob-and-tube era framing means irregular cavities and voids that standard batt insulation never fits correctly. Then you have the 1960s and 70s tract homes and the mid-century apartment blocks along the 90802 to 90804 corridor, where exterior wall insulation was often skipped entirely at original construction. The result is that Long Beach insulation work usually means retrofitting irregular spaces, not filling clean new framing. We plan for that reality on every job, because assuming a uniform cavity is how material gets wasted and results disappoint.
Our Main Long Beach Services
Long Beach homeowners call us most about two services: attic insulation and spray foam. Each solves a different set of problems in this city’s specific climate and housing stock.
Attic Insulation in Long Beach
In Long Beach’s older bungalows and tract homes, the attic is where heat pours in during summer and where marine-layer moisture condenses during the rest of the year. Attic insulation here has to do double duty: slow heat transfer and handle humidity without trapping it. We often find decking rusted from decades of trapped moisture in 90803 and 90802 shoreline homes, a pattern you rarely see east of the 710. Retrofitting those cramped, irregular attic spaces without compressing the material or blocking eave vents is the skill that separates a good outcome from a damp one. Read the full breakdown on Attic Insulation in Long Beach.

Spray Foam Insulation in Long Beach
Spray foam makes sense in specific Long Beach situations: open-wall remodels where the lath and stucco are already off, hard-to-reach rim joists, and floor systems over unheated crawlspaces or garages. Closed-cell foam acts as an air barrier and vapor retarder in one step, which matters in a city where fog-belt moisture finds every gap. Open-cell foam, by contrast, is vapor-permeable, so it lets damp air escape rather than trapping it against old framing. That choice, open-cell versus closed-cell, is exactly the kind of material decision we make with you, not for you. Details are 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 is the only practical way to reach the irregular, hard-to-access cavities that dominate this city’s older housing stock. In a 1920s Craftsman with an attic you have to belly-crawl into, batt insulation rarely fills the voids around framing, old wiring, and plaster keys. Blown-in material, whether cellulose or fiberglass, flows into those irregular spaces and settles around obstacles, giving a continuous thermal layer without ripping out finished ceilings or walls. In Long Beach’s marine climate, the material choice matters: we recommend products that perform in the damp coastal air rather than whatever is cheapest on the truck.
We install blown-in material across the older homes of 90810, 90813, and 90814, as well as in the 1960s and 70s tract houses that were built with minimal attic insulation. For a deeper look at the method itself, see our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to under 4 inches, you can see bare ceiling joists, or rooms below the attic swing hot and cold through the day.
What it costs in Long Beach
Blown-in cellulose in Long Beach typically runs $1.20 to $2.20 per square foot installed, depending on depth and access conditions.
How we do it
We air-seal the penetrations, blow the cellulose to the target R-value across the entire attic floor, and verify final depth with a gauge so you are not guessing how much material actually went in.
Blown In Attic Insulation
Signs you need it
Your upstairs rooms are consistently 8 to 10 degrees warmer than the rest of the house on sunny afternoons, and the attic floor shows gaps, thin spots, or visible framing.
What it costs in Long Beach
Blown-in attic insulation in Long Beach generally ranges from $1.50 to $3.00 per square foot, varying by existing material, depth target, and whether we need to remove old damaged layers first.
How we do it
We assess existing material, remove anything wet or moldy, baffle the eave vents so airflow continues, then blow fresh material to a uniform, measured depth across every section of the attic floor.
Blown In Fiberglass Insulation
Signs you need it
The current fiberglass batts are compressed, water-stained, or pulled back from the eaves, leaving visible thermal gaps at the edges of every room.
What it costs in Long Beach
Blown-in fiberglass typically falls between $0.80 and $1.60 per square foot installed in Long Beach, often the lower-cost option when depth targets are modest.
How we do it
We blow loose-fill fiberglass with calibrated equipment to reach the specified R-value, keeping the material fluffy and uncompressed so the trapped air stays trapped and the R-value holds.

Is blown-in insulation worth it in Long Beach?
Yes. In homes with attics that get direct sun and rooms that overheat by late afternoon, blown-in insulation reduces heat transfer and evens out indoor temperature swings. Call (833) 390-3099 for a Long Beach-specific quote based on your attic’s actual dimensions and existing material.
Can you install blown-in insulation the same day?
In most Long Beach attics under 1,500 square feet, yes, a standard blown-in job is completed in a single day. Call (833) 390-3099 to confirm current scheduling and get a time window.

Neighborhoods We Serve in Long Beach
We work across Long Beach from the shoreline flats to the inland tract blocks.

FAQs About Insulation Company in Long Beach
Most insulation retrofits in existing Long Beach homes do not require a building permit, since they are considered maintenance within the existing envelope. If spray foam is part of a larger remodel that touches framing or square footage, the remodel permit covers it. We can tell you which situation applies to your job.
In most Long Beach neighborhoods, we can schedule an estimate within one business day and complete most blown-in attic jobs within the same week. Spray foam jobs depend on material curing time and weather, but we confirm a schedule before any work begins.
Does marine air from the ocean affect which insulation I should choose?
Yes. In the 90803 and 90802 shoreline zone, fog and salt moisture make vapor permeability the first question. Open-cell foam or cellulose lets damp air migrate instead of trapping it against old decking. Inland 90805 and 90808 homes face more heat gain, so ventilation and radiant performance matter more. The right material depends on which side of the 710 you are on.

What Long Beach Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Justin Chen"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
