Frequently Asked Questions
− How do I know if my San Rafael attic insulation needs replacement?
Common local signs include uneven temperatures between floors (the top floor typically runs 7–12°F warmer on summer afternoons), PG&E bills that climb 15–25% with no change in usage, musty overnight smells, insulation that looks flat or matted, and any rodent activity. We see all of these on San Rafael inspections every week.
+ How much does attic insulation cost in San Rafael?
Most attic insulation projects in San Rafael 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 access. We confirm a fixed quote after the free inspection so there are no surprise add-ons.
+ What R-value does my San Rafael attic need?
California Title 24 requires R-38 in Climate Zone 3 (San Rafael valley floor and most of downtown) and R-49 in Climate Zone 2 (inland-hill pockets where Mt. Tam air drains overnight). Your specific address determines which applies. We measure and install to code, with documentation for your records.
+ Do you handle rodent-damaged insulation in San Rafael?
Yes — one of our most common San Rafael jobs, given the older housing stock. We vacuum the contaminated insulation, sanitize with EPA-registered products, seal every entry point and install fresh insulation matched to your home.
+ How long does an attic insulation project take in San Rafael?
A standard insulation-only upgrade 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 size, access and depth requirements.
+ Where do most air leaks happen in a San Rafael attic?
Most leaks come from recessed lights, plumbing stacks, attic hatches, bath fan ducts, and the top plate around the perimeter. We photograph each one during the inspection and seal them before installing new insulation. This single step usually moves your PG&E bill the most.
+ Are attic insulation rebates available in San Rafael?
Yes — federal IRA Section 25C and local utility rebates apply on most San Rafael attic insulation jobs that hit Title 24 R-values. We pre-qualify your project during the free inspection and submit the paperwork so you only pay the net cost.
+ Are you licensed and insured to work in San Rafael?
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 San Rafael neighbourhood and zip code.
