Insulation Company in Santa Monica, CA
If you’re calling an insulation company in Santa Monica, the odds are good that your attic is sagging, your walls feel damp, or one room runs cold no matter what the thermostat says. Blown-in insulation is the work most homes here need first, because it reaches the odd corners, settled cavities, and low-clearance attics common in the 1920s-1940s bungalows and mid-century stucco apartments that make up so much of the city. The marine layer changes the math, too: in Santa Monica, moisture control and air sealing often matter more than adding another layer of material. Call (866) 942-5951 for a free estimate.
Why Santa Monica Homes Are Different
Santa Monica sits right on the Pacific, and the marine layer is the defining force in almost every insulation job we look at. Bungalows and apartments within a mile or two of the water face persistent damp, condensation on cool surfaces, and salt-laden air that breaks down batts and vapor barriers far faster than the dry inland heat of neighboring Los Angeles. That’s a moisture-and-air-sealing problem as much as an R-value one, and it’s a different job than the same square footage in Culver City or the Valley.
The housing stock reinforces it. Much of Santa Monica is single-story California bungalows and duplexes from the 1920s through the 1940s, alongside 1950s-70s stucco apartment buildings and newer condo towers near the coast and along Ocean Park. Many older homes have minimal or settled wall and attic insulation, cavities from the knob-and-tube era, and pier-and-beam or slab floors that complicate retrofit access. The mild coastal climate means rare hard freezes and modest heating and cooling loads, so insulation value here is less about extreme temperature swings and more about controlling the damp marine-layer moisture and sealing the envelope year-round.
Our Main Santa Monica Services
Two jobs come up more than any other in Santa Monica: upgrading attic insulation in older homes and sealing leaky or previously insulated cavities with spray foam.
Attic Insulation in Santa Monica
Attic work in Santa Monica usually means dealing with settled or compressed batts, a vapor barrier installed on the wrong side, and a low, hot attic that’s hard to move through. We start by checking moisture before we add anything, because trapping damp under new material causes more trouble than it solves. Insulation is all we do, so the recommendation follows your structure rather than whatever a general contractor happens to carry. For the full breakdown of materials, brands, and pricing on this scope, see Attic Insulation in Santa Monica.
Spray Foam Insulation in Santa Monica
Spray foam earns its keep here on air sealing and condensation control, especially in stucco apartments and ocean-close homes where cold surfaces collect moisture. We work with both Icynene and Demilec across open-cell and closed-cell applications, so the choice comes down to whether your cavity needs vapor control, sound control, or simply a tighter seal. Older pier-and-beam floors and rim joists are common retrofit targets. The details, including costs and sub-jobs, live on Spray Foam Insulation in Santa Monica.
Blown In Insulation in Santa Monica
Blown-in insulation is the practical answer for most Santa Monica attics, because it fills the irregular cavities and low-clearance spaces that batt material can’t reach well. In a 1920s bungalow or a 1950s stucco apartment, loose-fill material settles into the gaps left behind by compressed, musty old batts, and it lets us treat the whole envelope in a single pass instead of fighting around obstructions. You can read more about the method on our Blown In Insulation page.
The marine layer is what changes the job in Santa Monica specifically. Salt-laden coastal air and persistent damp break down older material and, in ocean-close neighborhoods like Ocean Park and north of Wilshire, technicians routinely find vapor barriers facing the wrong way. So we treat blown-in as a moisture-and-air-sealing job first. Before any material goes in, we check the attic for damp, air-seal the bypasses, and confirm the cavity is dry enough to hold new insulation. That step is why blown-in goes further here than simply piling material on top of what’s already there.
Cellulose Insulation
Signs you need it
You’ll know it’s time when your attic material looks packed down and musty, your utility bills creep up in mild weather, or rooms along the coastal side of the house feel cold and clammy even when the inland rooms are comfortable.
What it costs in Santa Monica
Blown-in work in Santa Monica typically runs $1,415 to $4,130, depending on the attic area, existing material, and how much air sealing is needed before installation; the written estimate sets the final price.
How we do it
We air-seal the attic floor and any obvious bypasses first, then blow GreenFiber cellulose to a consistent depth across the whole surface, working around obstructions so there are no cold pockets left behind.
Blown In Attic Insulation
Signs you need it
A home where the attic has never been properly insulated, or where old batts have compressed to a fraction of their original thickness, is the clearest signal that a full attic upgrade is overdue.
What it costs in Santa Monica
Attic insulation in Santa Monica typically runs $1,770 to $5,310, and the final estimate depends on attic size, access, and how much prep work the older structure needs.
How we do it
We inspect the attic for moisture and existing material, seal the bypasses, then blow material to a consistent depth, checking coverage at the far corners and around any ductwork or recessed ceiling fixtures.
Blown In Fiberglass Insulation
Signs you need it
If your old material has lost its loft or you’re dealing with a large open attic where a stable, well-known material makes sense, blown-in fiberglass is often the right pick.
What it costs in Santa Monica
Blown-in work here typically falls in the $1,415 to $4,130 range, but the written estimate after an attic visit is what sets your actual price.
How we do it
We air-seal first, then blow Owens Corning or Knauf fiberglass evenly across the attic, taking care to keep soffit vents open so the space can breathe as it’s meant to.
What Blown In Insulation Costs in Santa Monica
These are typical estimated ranges for the Santa Monica market. Your written estimate after an attic visit is what sets the final price, because access, existing material, and moisture issues all move the number.
| Item | Typical range in Santa Monica |
|---|---|
| Blown-in insulation | $1,415 – $4,130 |
| Blown-in attic insulation | $1,770 – $5,310 |
| Insulation removal & replacement | $1,770 – $6,490 |
Can blown-in insulation help with Santa Monica’s coastal damp?
It can, but only if air sealing and moisture control come first. We check for damp before adding material, seal the bypasses, and confirm the cavity is dry so new insulation doesn’t trap moisture. Call (866) 942-5951 for a free estimate.
Do I need to remove old insulation before adding blown-in?
Not always. If the existing material is dry and intact, we can often add over it. Compressed, musty, or water-damaged material usually needs removal first, and we’ll tell you which applies after an attic visit.
Brands We Service in Santa Monica
We carry eight brands so you’re not limited to what’s on a single installer’s shelf: Owens Corning, Johns Manville, Knauf, CertainTeed, Rockwool, Icynene, Demilec, and GreenFiber. That breadth spans fiberglass, mineral wool, spray foam, and cellulose, so the material matches your structure rather than the other way around. Availability and lead times for any given line are confirmed on your estimate, so you know what to expect before install day. See our brands for the full roster.

What Santa Monica Customers Say
"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."
- Shannon Kowalski"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
- Amit Rao"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
- Marco Hernandez
