Insulation Company in Santa Monica, CA
Blown In Insulation is the service Santa Monica homeowners call us about most, and for good reason. The city’s 1920s – 1940s bungalows south of Montana and around Ocean Park were built before wall insulation was standard, which means heat slips out through uninsulated cavities and damp Pacific air finds its way in. North Tustin Insulation has served Santa Monica since 2011, matching the right material to each home’s construction rather than forcing a one-size-fits-all fill. Call (877) 265-5712 for a free estimate.
Why Santa Monica Homes Are Different
Santa Monica’s housing stock creates insulation challenges you won’t find ten miles inland. The 1920s – 1940s single-wall and wood-frame bungalows in Ocean Park and Sunset Park often have no wall cavities at all, just wood lath and plaster over studs. Knob-and-tube wiring in these older homes complicates any retrofit. Then there’s the climate: the marine layer rolls in most mornings, onshore humidity keeps exterior walls damp for hours, and standard fiberglass batts installed without vapor management can trap that moisture against old growth redwood framing. In Santa Monica, the primary job of insulation is rarely about extreme heat or cold. It’s about controlling air movement and keeping trapped Pacific moisture away from wood that has been in place for nearly a century. We approach every Santa Monica job as a moisture-management project first, because a dry wall cavity is a wall cavity that performs.
Our Main Santa Monica Services
Two services drive most of our Santa Monica work: attic insulation and spray foam. Each page below covers that service in depth for Santa Monica homes.
Attic Insulation in Santa Monica
Most Santa Monica attics are under-insulated by modern standards. Older bungalows often have a thin layer of rock wool or fiberglass from a remodel decades ago, compacted by years of coastal humidity. We remove what’s failing and bring the attic floor to current code using blown-in fiberglass or cellulose, depending on venting and existing wiring. Ventilation matters here: a Santa Monica attic that doesn’t breathe will hold moisture from the marine layer against the underside of the roof deck. Read the full breakdown on our Attic Insulation in Santa Monica page.
Spray Foam Insulation in Santa Monica
Spray foam earns its keep in Santa Monica when a homeowner wants to seal the building envelope. Open-cell foam works well in vented attics and crawl spaces where breathability matters. Closed-cell foam is the right call for rim joists or for adding structural rigidity to an older single-wall home. The material choice depends on the wall assembly and how the house handles moisture today. See the full material and pricing breakdown on our Spray Foam Insulation in Santa Monica page.

Blown In Insulation in Santa Monica
Blown In Insulation is the most efficient way to add real thermal performance to the walls and attics of Santa Monica’s older homes. In Ocean Park and Sunset Park, the original 1920s – 1940s wood lath and single-wall construction leaves almost no room for batts, and drilling into lath with knob-and-tube wiring nearby requires a method that can be directed around obstacles. Blown-in material flows into irregular cavities, fills gaps around old framing, and reaches areas a batt could never touch. Because Santa Monica’s coastal air stays damp through the morning marine layer, we choose moisture-tolerant blown-in materials and pay close attention to vapor drive so the insulation doesn’t hold water against old wood. We offer several blown-in systems, including Blown In Insulation using GreenFiber cellulose and CertainTeed fiberglass.
Blown In Attic Insulation
Signs you need it
Your upstairs rooms feel warmer than the rest of the house by midafternoon, or your attic floor has less than six inches of loose material across most of its surface.
What it costs in Santa Monica
Blown in attic insulation in Santa Monica runs about $2.50 – $5.50 per square foot depending on existing material removal, venting, and target depth.
How we do it
We air-seal penetrations and top plates, check that soffit and ridge vents are not blocked, then blow loose-fill material to the specified R-value with a guarded blower hose.
Blown In Cellulose Insulation
Signs you need it
Your walls feel hollow when you knock on them, or you notice drafts near outlets on the interior walls of your older bungalow.
What it costs in Santa Monica
Blown in cellulose for wall cavities in Santa Monica’s older homes typically runs $3.00 – $5.00 per square foot, with GreenFiber recycled cellulose as the standard material.
How we do it
We drill small access holes through lath or drywall, snake the blower hose into each stud bay, dense-pack the cellulose to prevent settling, then patch the holes cleanly.
What Blown In Insulation Costs in Santa Monica
| Item | Typical range in Santa Monica |
|---|---|
| Blown in attic insulation | $2.50 – $5.50 per sq ft |
| Blown in wall cellulose | $3.00 – $5.00 per sq ft |
| Loose fill insulation | $2.00 – $4.50 per sq ft |
Is blown in insulation worth it in Santa Monica’s climate?
Yes. Santa Monica’s mild temperatures don’t demand heavy R-value, but the real win is air-sealing around old lath, knob-and-tube wiring, and irregular framing, which cuts drafts and keeps moisture out of wall cavities.
Can you blow insulation into single-wall Santa Monica bungalows?
We can. Single-wall construction needs a dense-pack approach and careful vapor strategy so the material doesn’t trap coastal humidity. Call (877) 265-5712 for an exact quote.

We stock and install a focused set of brands from our eight-brand portfolio for Santa Monica homes, including CertainTeed fiberglass, GreenFiber cellulose, and Icynene spray foam. Material is ordered per job, so you’re never getting a partial bag pushed onto your project from the back of a truck.
