Service Description
Full-service attic insulation in Novato
Every Novato job starts with the same inspection, removal, install and sealing workflow — no shortcuts, no subcontractors.
Full vacuum removal
Old insulation extracted with high-powered vacuum trucks — no debris through the house, no contamination left behind. Standard on every Novato job that has 20+ year-old material.
Blown-in cellulose or fiberglass
Machine-installed loose-fill to reach R-38 / R-49 Title 24 depth in Novato — full coverage, no gaps, no cold spots in those long San Marin eaves.
Air sealing pair
Every recessed light, plumbing stack and attic hatch sealed before we close. Stops the lion's share of conditioned-air loss — especially in Hamilton ranch homes with attic-within-attic layouts.
Code & paperwork
CF-3R documentation filed with Marin County, Title 24 compliance verified for your specific Climate Zone, and PG&E rebate paperwork submitted on your behalf.

Frequently Asked Questions
− How do I know if my Novato attic insulation needs replacement?
Common signs in Novato homes include upstairs rooms running 8–14°F hotter on summer afternoons, PG&E bills climbing 15–25% with no change in usage, dark or matted insulation in the eaves, rodent droppings (deer mice are very common this close to open space), and a musty smell after the first cold snap. Hamilton, Ignacio and San Marin tract homes from the 70s/80s almost always underdeliver on current Title 24 depth.
+ How much does attic insulation cost in Novato?
Most attic insulation projects in Novato run between $1.75 and $4.50 per square foot, depending on material (blown-in cellulose, blown-in fiberglass, or batts), depth required for Title 24 compliance, existing condition and attic access. We confirm a fixed written quote after the free in-home inspection so there are no surprise add-ons.
+ What R-value does my Novato attic need?
Most Novato addresses fall under California Title 24 Climate Zone 4 (Marine), which requires R-38 minimum — but pockets of Bel Marin Keys and the inland-resident hills register as Zone 12 where R-49 applies. Your specific address tells us which zone you are in, and we document it on the CF-3R form for the county.
+ Do you handle rodent-damaged insulation in Novato?
Yes — Novato is one of our busiest cities for rodent-damaged insulation because so many homes back up against open-space preserves along the north side of town. We vacuum the contaminated insulation, disinfect with EPA-registered products, seal every gap we find (including the classic attic-to-eaves and roof-to-fascia entry points), and install fresh insulation matched to your home.
+ How long does an attic insulation project take in Novato?
A standard insulation-only upgrade in Novato is finished in a single day. Full restoration — vacuum removal, sanitization, rodent sealing, air sealing and new insulation — typically runs 1 to 2 days depending on attic square footage, depth required for your climate zone and access. Homes in Bel Marin Keys and waterfront pockets sometimes add half a day because of dock/gate access.
+ Where do most air leaks happen in a Novato attic?
Common leak points we see on Novato jobs include recessed can lights in older ranch homes, plumbing penetrations around upstairs bathrooms, attic hatches in garage ceilings (very common in Hamilton), whole-house fan boots, and the top plate around the perimeter. We photograph each one during the inspection and seal them before installing new insulation.
+ Are attic insulation rebates available in Novato?
Yes — federal IRA Section 25C and PG&E whole-home rebate programs apply on most Novato attic insulation jobs that hit Title 24 R-values. We pre-qualify your project during the free inspection and submit the rebate paperwork for you, so you only pay the net cost after the utility check arrives.
+ Are you licensed and insured to work in Novato?
Yes — fully licensed California State License Board (CSLB) contractor with general liability and workers' comp coverage in place. We share documentation before any work begins. Serving every Novato neighbourhood — downtown, Hamilton, Ignacio, San Marin, Loma Verde, Bel Marin Keys, Black Point and beyond.
