Insulation Company in Sonoma, CA
Laurel Attic Insulation is the insulation company Sonoma homeowners call when they want a written price before work starts and a live arrival time on the day of the job. Homes across Sonoma range from 1970s ranchers near the Plaza to newer builds east of Broadway, and nearly all of them lose conditioned air through under-insulated attics and crawl spaces. If you’re comparing insulation contractors in Sonoma, call (361) 315-4177 and we’ll walk you through what your house actually needs.
Why Sonoma Homes Are Different
Sonoma’s summer heat is a dry inland heat. Afternoon temperatures regularly push into the 90s from June through September, and that heat hits your roof deck all day before radiating down into living space. The fix is an attic that actually slows that heat transfer, and in Sonoma the starting point is almost always R-value. R-value is the number that measures how well insulation resists heat moving through your ceiling. Most Sonoma attics we inspect sit between R-19 and R-30, where current building code for this climate zone calls for R-38 to R-60.
Housing stock matters too. A 1960s ranch off Fifth Street West has very different framing, venting, and access than a 2000s production build in the hills near Lovall Valley. Older Sonoma homes often have shallow attic cavities, low-pitch roofs, and original batt insulation that settled years ago. Newer homes tend to be tight but sometimes skip proper air sealing at the top plate. Neither is a one-size-fits-all job, and we price each one after looking at the actual attic, not a square footage average.
Our Main Sonoma Services
Attic insulation and insulation removal are the two calls we get most from Sonoma homeowners. Spray foam comes in close behind, especially for people converting garages or finishing bonus rooms. Here’s what each one looks like in Sonoma.
Attic Insulation in Sonoma
This is the workhorse job for Sonoma homes. We remove old or thin insulation when needed, air-seal the attic floor, and install new material to bring the assembly up to R-38 or higher. In Sonoma, blown-in fiberglass and blown-in cellulose are the most common choices because they settle into the irregular cavities of older framing without leaving gaps. Owens Corning fiberglass is a staple on our trucks, and we keep enough on hand for most single-day installs. Full details including Sonoma-specific pricing and what to expect on install day are on the Attic Insulation in Sonoma page.
Spray Foam Insulation in Sonoma
Spray foam is the right tool for Sonoma homes with low-pitch roofs, unvented attics, or bonus rooms above unconditioned garages. Closed-cell foam doubles as an air barrier, which matters in summer when hot air tries to drive through every seam and penetration in the building envelope. We install Icynene and Demilec closed-cell systems on Sonoma jobs, and our techs quote the board-foot counts before anything is sprayed. See the Spray Foam Insulation in Sonoma page for the conditions where foam beats batts and what it runs per square foot here.
Insulation Removal in Sonoma
Rodents, water damage, and decades of dust all have one thing in common: the insulation has to come out before anything else happens. In Sonoma, removal is most common in older homes where original fiberglass batts have been compromised by roof leaks or animals. We use HEPA-filtered vacuum systems that pull everything out clean, then we prep the cavity for whatever goes back in. The Insulation Removal in Sonoma page explains when removal is required versus optional and what a full small-home removal costs here.

Price in Sonoma moves most on square footage and existing R-value. A 1,200-square-foot rancher with bare joists costs less than a 3,000-square-foot hillside home with settled R-19 that needs full removal first. Either way, you get a written price before anything starts, and that number doesn’t change at the door.
