Sacramento Insulation and Weatherization Savings Guide

Insulation, air sealing, windows, and weatherization work can reduce project cost and lower the size of later HVAC work.

What to check first

• Get pre-work photos, attic depth, air-sealing notes, and contractor scope in writing.
• Check federal 25C rules for insulation, windows, doors, and energy audits.
• Verify whether state-administered home energy rebates are open before work starts.
• Keep receipts, product specifications, and any required pre-approval documents.

Documents to gather

• ZIP code, utility provider, and project timeline.
• Contractor quote with equipment, labor, permit, and add-on costs separated.
• Product model numbers, efficiency ratings, and warranty details.
• Photos or inspection notes that may be needed before work begins.
