Insulation Company in Santa Monica, CA
Woolsey Attic Insulation is the insulation company Santa Monica homeowners call when they discover what the marine layer has been doing inside their walls. The city’s narrow temperature band hides problems well – you won’t get a shivering-cold bedroom clue the way a Tarzana homeowner would. What you’ll get instead is a surprise during a remodel: saturated batts, compressed fiberglass, or empty cavities that Santa Monica’s Green Building Ordinance now says must be insulated before the permit closes. We handle attic insulation and spray foam insulation here, with a written price before any work starts. Call us at (325) 240-5411 when you’re ready to know the real number.
Why Santa Monica Homes Are Different
Santa Monica’s pre-WWII craftsman bungalows and Spanish Revival homes concentrated in North of Montana and Sunset Park carry a specific problem: wall cavities with original rock wool or nothing at all, coupled with stucco exteriors that wick coastal moisture straight inward. Then there’s the 1950s-to-1970s wood-frame apartment stock, much of it held in place by decades of rent control and tenant-in-place constraints, where fiberglass batts have compressed or shifted and no one has opened the walls since the day they were built.
The marine layer is the real differentiator. Salt-laden air and persistent humidity mean insulation in Santa Monica is first a moisture-management job, second a thermal one. Closed-cell spray foam and properly faced batts with vapor retarders on the correct side matter here in ways they don’t ten miles inland. Mild outdoor temperatures mean poorly insulated walls rarely trigger comfort complaints – so saturated cavity insulation and the mold behind it sit undetected until a renovation or inspection exposes the damage. That’s the Santa Monica pattern we see repeatedly.
Our Main Santa Monica Services
Two services make up nearly every call we take in Santa Monica, each with its own dedicated page covering local conditions, pricing, and process.
Attic Insulation in Santa Monica
Santa Monica attics run hot despite the mild coastal air, and older bungalow attics often hold nothing but a thin layer of dust-covered fiberglass that flattened years ago. We assess the existing R-value, air-seal the bypasses that let conditioned air escape, and install blown-in cellulose or fiberglass to the depth your home’s framing will support. In North of Montana and Sunset Park homes, we frequently find old knob-and-tube wiring that must be navigated carefully. Full details on Attic Insulation in Santa Monica.
Spray Foam Insulation in Santa Monica
Spray foam – a two-part liquid that expands on contact and seals gaps airtight – solves problems Santa Monica’s coastal humidity creates. Closed-cell foam acts as both insulation and a moisture barrier, which is why we specify it for stucco-walled bungalows where cavity condensation is a real risk. Injection foam through exterior stucco is one of the most common multi-family retrofit jobs we do in the city. Open-cell foam suits attic rooflines where ventilation can be managed.

Every job gets a written price before anything starts, and the Kingswell Guarantee puts the same details in writing: a committed arrival window, a clean job site, and 365 days of accountability after.

What Santa Monica Customers Say
"Insulation job was done well. Scheduling took a little longer than I'd have liked, they were booked out a couple weeks. But once they came it was quick and the house is cozier."
- Felicia Grant"The guy didn't try to sell me on foaming the whole house. He said the attic was where I'd actually feel it and left it at that. Honest, and he was right, our bills dropped."
- Angela Ruiz"Drafty old house that never felt comfortable. After the attic and some air sealing it's a different place. On time, clean, and the quote didn't change. Wish I'd done it years ago."
- Dmitri Kozlov
