Weatherization in Vermont.

Why now · Vermont

Propane and oil bills have climbed every year.

Vermont propane climbed from $2.40/gal in 2010 to $3.50+/gal by 2025. Weatherization cuts your fuel usage by 25-35% on day one, so your bill drops by that much before the next price hike.

06 · Questions Homeowners Ask

The honest FAQ.

Actual questions that come up in the first installer conversation, answered for a typical Vermont homeowner in 2026.

Does the 90% weatherization rebate actually exist?

Yes, but it's limited-time funding from the Vermont Department of Public Service, authorized through December 31, 2026. After that, it reverts to the standard rebate structure (lower but still generous). Act now.

What if I'm off-grid?

Off-grid homeowners can still use Efficiency Vermont insulation and appliance rebates. Heat pump rebates technically require utility interconnection, though Vermont has made exceptions for high-battery off-grid homes case-by-case.
