Insulation Company in Palo Alto, CA
Woolsey Attic Insulation is an insulation company built around Palo Alto’s housing reality, which means we deal with Eichlers, Craftsman bungalows, and Title 24-triggered rebuilds more than any other type of home. Our two trades are attic insulation and spray foam insulation, and each has its own Palo Alto page linked just below. The short version: Palo Alto homes rarely fail from extreme cold or heat. They fail because post-and-beam construction, single-pane glass, and 30°F daily temperature swings expose every gap the original builder left behind. If you’d like a written price before any work starts, call (325) 240-5411.
Why Palo Alto Homes Are Different
Palo Alto contains one of the highest concentrations of Eichler homes in the Bay Area. These mid-century post-and-beam houses have flat or low-slope roofs, radiant heat in concrete slabs, and virtually no conventional attic space. You cannot blow cellulose into an Eichler the way you would a ranch home in Barron Park or a Craftsman in Old Palo Alto. The work requires rigid polyiso foam above the roof deck, injection foam into shallow 2×4 stud bays, and careful handling around the slab radiant system. That’s a completely different job, priced accordingly.
Beyond the Eichlers, the city’s housing stock splits between prewar Craftsman bungalows in Old Palo Alto and Crescent Park, postwar ranch homes, and the teardown-rebuild projects that now dot Midtown and South Palo Alto. Those new builds must meet Title 24 from the ground up, which means insulation becomes part of the permit conversation before framing even starts. Palo Alto’s marine-influenced climate keeps summers below 85°F and winters nearly frost-free, so the real comfort driver is the 25 – 35°F swing between afternoon and night. Airtightness and thermal bridging control matter more here than raw R-value in a blizzard. Palo Alto Utilities (CPAU), the city’s independent municipal utility, runs its own rebate programs on different terms than PG&E, and pairing those rebates with the city’s electrification ordinance changes the math on nearly every retrofit.
Our Main Palo Alto Services
Palo Alto homeowners call us most often for the two jobs below. Each has its own page, including pricing, process, and what to expect on a Palo Alto-specific install:
Attic Insulation in Palo Alto
Attic insulation in Palo Alto starts with what kind of attic you actually have. A standard ranch in Barron Park may need blown-in fiberglass or cellulose to hit Title 24 compliance before a renovation or sale. An Eichler in Midtown has no attic at all, so insulation goes above the roof deck instead. We work with Owens Corning, Johns Manville, and Knauf, and we write a price before any work starts. Full details are on the Attic Insulation in Palo Alto page.
Spray Foam Insulation in Palo Alto
Spray foam insulation is a two-part liquid that expands on contact and seals gaps airtight, and it earns its keep in Palo Alto because the real problem here is air movement through post-and-beam framing and single-pane glass walls. Open-cell foam goes into interior cavities where noise and airflow matter; closed-cell adds structural and moisture benefits. For the full breakdown on costs, foam types, and what works in Palo Alto’s climate, see Spray Foam Insulation in Palo Alto.

It depends on scope. Simple attic air sealing and blown-in insulation usually don’t require a permit, but anything tied to a renovation with Title 24 triggers or exterior roof-deck work on an Eichler often does. We’ll tell you exactly what’s needed before we write the price.

What Palo Alto Customers Say
"Showed up on time, laid down protection on the floors, and were careful going into the attic. Explained exactly what they were doing and why. House holds its heat so much better now."
- Preston Hale"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."
