Insulation Company in Bellflower, CA
Most homes in Bellflower were built between 1950 and 1965, and almost none of them had wall insulation from the start. That single fact shapes nearly every insulation job we do in the 90706 and 90707 ZIP codes. We’re Fountain Valley Insulation, and our most common Bellflower project is blown in insulation, retrofitted into wood framed, stucco sided tract homes that were never designed for it. Summers here routinely hit the 90s, and a home with empty stud cavities leaks cooled air all afternoon. Call us at (833) 390-3099 for a free estimate, and we’ll tell you exactly what your walls and attic actually need.
Why Bellflower Homes Are Different
Bellflower’s housing stock is unusually uniform for Southern California. Block after block is lined with post WWII single family tract homes from the 1950s and 1960s, mostly wood frame under stucco, with drywall or older lath and plaster inside. Those builders put insulation in very few walls. Attics got a thin layer if they got anything at all, and sixty years of settling has compressed much of that to near nothing. We’re not working on new construction here. We’re working on retrofit detailing.
The climate pushes the other half of the problem. Bellflower sits close enough to the coast to catch marine layer mornings, but far enough inland that summer afternoons climb into the 90s. That means the insulation conversation in Bellflower is about cooling, not freeze protection. Holding air conditioned air inside matters more than keeping cold out. Attic floor insulation, radiant barriers, and wall cavity fill do the heavy lifting. And because most Bellflower walls are stucco over wood frame, wall retrofits usually access the stud cavities from outside, through the gable end or along the eave line at the top plate. It’s a detail that shapes every wall job we bid in the 90706 ZIP, and it’s why Bellflower work rewards a contractor who has done this specific kind of retrofit many times.
Our Main Bellflower Services
Bellflower homeowners call us most often about two projects: getting their attic insulation brought up to something that actually works, and sealing the building envelope with spray foam. Both have their own dedicated Bellflower pages.
Attic Insulation in Bellflower
Original attic insulation in Bellflower tract homes is often down to two or three inches of settled, dusty fiberglass under a low pitch roof. That’s nowhere near what a 90706 attic needs to keep a 90 degree afternoon from turning the upstairs into an oven. We remove what’s degraded, air seal the ceiling plane, and blow in fresh material to the depth that matches your home’s framing and venting. Attic Insulation in Bellflower has the full breakdown of what we see in these attics and what it costs to fix.
Spray Foam Insulation in Bellflower
For Bellflower homes with crawlspace or knee wall problems, or for homeowners who want air sealing and insulation in one pass, spray foam is often the right answer. Closed cell foam performs well in the damp mild winters we get here, and it adds structural rigidity to older wood framing. Spray Foam Insulation in Bellflower explains the difference between open and closed cell and where each makes sense in a mid century California house.

Blown In Insulation in Bellflower
Blown in insulation is the workhorse retrofit for Bellflower’s 1950s and 1960s tract homes. Most of these houses have empty stud cavities behind the stucco, with maybe an inch of settled attic fiber if the original builder bothered at all. Dense packing those walls and raising the attic floor to a proper R value is the single biggest comfort improvement most Bellflower homeowners can make, and it’s the job we do more than any other in 90706 and 90707. For a full walkthrough of the material and method, visit our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Rooms that get noticeably hotter than the rest of the house by mid afternoon are a classic sign that settled or missing wall and attic insulation is letting heat move through the framing.
What it costs in Bellflower
Loose fill cellulose for a Bellflower attic or wall retrofit typically falls between $1.50 and $3.50 per square foot installed, depending on depth and access.
How we do it
We dense pack the existing stud cavities through small access points at the top plate or gable end, then blow the attic floor to a consistent depth that meets the target R value for Bellflower’s cooling driven climate.
Blown In Attic Insulation
Signs you need it
If your attic has less than six inches of material across the ceiling joists, or you can see the joist tops clearly, you’re under insulated for a Bellflower summer.
What it costs in Bellflower
Blown in attic insulation in Bellflower generally runs $1.50 to $3.50 per square foot, with older low pitch attics sometimes pushing labor higher.
How we do it
We air seal the ceiling plane penetrations first, then blow loose fill across the joists to the depth your attic framing and venting will support.
Blown In Cellulose Insulation
Signs you need it
Drafty baseboards and interior walls that feel warm to the touch in summer point to empty cavities below the top plate that dense pack cellulose can fill.
What it costs in Bellflower
Dense pack blown in cellulose for Bellflower wall retrofits is usually $1.50 to $3.50 per square foot of wall area, not including any stucco patch work.
How we do it
We drill small access holes at the eave line or from the gable end, dense pack the cellulose into each stud bay, and leave the interior drywall untouched.
Blown In Fiberglass Insulation
Signs you need it
Homes with older, dusty batts that have slumped away from the drywall are good candidates for blown in fiberglass, which settles less and fills irregular joist bays more completely.
What it costs in Bellflower
Blown in fiberglass in Bellflower attics and walls is priced similarly at $1.50 to $3.50 per square foot installed, with depth driving material volume.
How we do it
We remove the degraded batts where needed, then blow fiberglass to a consistent depth and density, including around ducts and electrical runs that batts never fit well.
Loose Fill Insulation
Signs you need it
Low spots and bare patches across an attic floor, especially near the eaves where older material has drifted, call for a full loose fill re-blow.
What it costs in Bellflower
Loose fill insulation for a Bellflower attic typically lands between $1.50 and $3.50 per square foot, depending on the existing depth and how much removal is required.
How we do it
We either top up the existing loose fill or remove and re-blow it entirely, ensuring a flat, even depth that holds its R value across the whole attic.

Does blown in insulation work in old Bellflower walls?
Yes, and most Bellflower tract homes are actually ideal for it. The stucco over wood frame construction leaves a clean stud cavity we can dense pack from the outside without opening your drywall. Call (833) 390-3099 to have your walls inspected.
Can you do blown in insulation the same day in Bellflower?
Most attic re-blows in Bellflower are a same day job. Wall retrofits can take a second day if there’s a lot of stucco patch detail. Call us for a schedule estimate based on your square footage.

What Bellflower 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."
