Insulation Company in Cotati, CA
Laurel Attic Insulation is the insulation company Cotati homeowners call when they want the job done right, with a written price in hand before any work starts. Cotati’s mix of 1970s and 1980s ranch homes, newer subdivisions, and rural properties east of Highway 101 creates real variety in what an insulation job requires. Some attics have fiberglass batts from the Reagan years. Others have settled blown-in cellulose doing almost nothing. We handle all three core services: attic insulation, spray foam insulation, and insulation removal. Call (361) 315-4177 any time, day or night, and a live person picks up.
Why Cotati Homes Are Different
Cotati sits in a gap in the coastal hills where summer heat builds into the 90s while winter nights drop near freezing. Homes here get hit from both directions. A house built in 1985 near Downtown Cotati often has R-19 in the attic, which is roughly half of what current California energy code calls for in this climate zone. That means the air conditioner works harder from late June through September, and the furnace works harder from November through February. Insulation in Cotati is about both seasons, not just one.
Housing stock varies block by block. The neighborhoods around Cotati Middle School and Thomas Page Academy skew older, with tight attic access and original ductwork that makes removal jobs more delicate. Newer communities like the subdivisions south of Sierra Avenue and west of Old Redwood Highway have truss attics that are friendlier for spray foam applications. Rural properties east of town toward Sonoma Mountain often have outbuildings and bonus rooms with no insulation at all. Each job starts with a look at what’s actually above the ceiling, not a guess based on ZIP code.
Our Main Cotati Services
Most Cotati homeowners reach out for one of three reasons: a cold house in winter, a hot house in summer, or contaminated insulation that needs to come out before anything new goes in.
Attic Insulation in Cotati
We pull back the mystery of what’s happening above your ceiling. Attic insulation jobs in Cotati typically mean air-sealing the top plates, adding or replacing insulation to hit R-38 or R-49 (R-value is the number that measures how well insulation slows heat moving through your ceiling), and making sure soffit vents stay clear. Many homes here have old fiberglass batts that were never installed to full depth. Attic Insulation in Cotati is the fix that pays back fastest on your energy bill.

Spray Foam Insulation in Cotati
Spray foam earns its keep in Cotati attics where ductwork runs through unconditioned space, a common setup in older ranch-style homes here. Foam seals the gaps that batts and blown-in material simply can’t reach. We use open-cell foam in most attics and closed-cell foam where moisture from foggy winter mornings is a concern. Spray Foam Insulation in Cotati solves air leaks and insulation in one pass.

Insulation Removal in Cotati
Old insulation collects more than you’d think: rodent droppings, dust, and in some Cotati homes, asbestos-tainted vermiculite from mid-century builds. Removal is a controlled, contained job with a HEPA-filtered vacuum, not a rake and a contractor bag. After removal, we sanitize the attic deck and prep the space for new insulation. Insulation Removal in Cotati is the first step when old material has failed or become a health concern.
