Insulation Company in Novato, CA
Thistledown Attic Insulation brings the Cedarwell Care Promise to every attic and crawl space we touch in Novato. Most insulation companies treat this city like any other, but Novato work has its own set of rules: 1960s ranch homes with settled fiberglass, fog-dampened attics, and temperature swings that stress vapor barriers. We’re the crew that lays drop cloths from your front door to the attic hatch, uses quiet tools when kids are napping, and puts your exact price in writing before any work begins. If you need insulation in Novato, call (341) 247-0222 and a live person answers, day or night.
Why Novato Homes Are Different
The homes we see in Novato tell a specific story. Most were built between the 1950s and 1980s with 2×4 walls and attic insulation that was thin even by the standards of the time, largely R-11 to R-19. Decades later, that fiberglass has settled, compressed by years of stored holiday decorations and boxes. The real problem though is what Novato’s climate does to these attics. Fog rolls in off San Pablo Bay and hangs over Pleasant Valley. Afternoon winds barrel through the Petaluma Gap. That combination means attics cycle through moisture and dryness in ways that degrade insulation faster than in drier inland cities. We often find that the actual issue isn’t just thin insulation, it’s air leakage around recessed lights in cathedral ceilings letting conditioned air escape while damp air moves through. Hamilton Field’s converted military housing adds another layer: those homes were built for a different purpose and retrofitted for residential living, which means odd framing, unconventional attic access, and insulation decisions that never anticipated a Marin County family living there full time. Every Novato job starts with understanding which of these conditions your home deals with.
Our Main Novato Services
Two services cover almost every insulation call we receive in Novato. Each has its own dedicated page with local pricing and specifics.
Attic Insulation in Novato
Most Novato attics we enter have original fiberglass batts that have been compressed, dampened, or disturbed by decades of storage and critters. We remove what’s failing, air-seal where the house leaks, and install clean insulation matched to your home’s construction. For families in Pleasant Valley with cathedral ceilings, we pay special attention to recessed light fixtures, a common source of hidden air leakage. The crew wears shoe covers from the front door to the attic hatch and leaves a photo of the clean-up before we go. Attic Insulation in Novato covers local pricing, the common problems we fix, and what to expect during the work.
Spray Foam Insulation in Novato
Spray foam works well in Novato’s older homes because it seals and insulates in one pass, which matters when fog moisture and Petaluma Gap winds push air through every gap in a 1960s ranch. We use products from Demilec and Icynene, chosen per job based on the space and your family’s needs. In crawl spaces, where Novato’s moisture levels demand careful vapor barrier work, closed-cell foam often makes the most sense. Every spray foam job comes with a written price before we start and our 365-Day Done Right Promise behind it. Spray Foam Insulation in Novato explains the process, local costs, and how we keep the work clean.

Brands We Service in Novato
We install products from Owens Corning, Johns Manville, and GreenFiber, among the eight lines we carry.

What Novato Customers Say
"Attic insulation. The crew laid down protection from the front door to the attic hatch and vacuumed up every bit of the old material. House holds its warmth now and there was zero mess."
- Rowena Platt"Careful and clean from start to finish. They covered the hallway, wore booties, and hauled off all the old material without leaving a speck. Respectful of the home the whole time."
- Brett Yamamoto"Removed the old flattened insulation and blew in new. They were so careful not to track anything through the house, booties on, drop cloths down. Cleaned up spotless after."
