Are there rebates for insulation in New Hampshire?

NHSaves offers energy audits and weatherization incentives such as insulation and air sealing, with enhanced help for income-eligible households. See our energy rebate guide.

Will insulation help with ice dams?

Yes. Air sealing and insulation keep warm air out of the attic, which is the lasting fix for ice dams. See our ice dam guide.

Do insulation contractors need a license?

New Hampshire doesn't issue a state license for insulation contractors, so check insurance, references and recent local work instead. Ask for a certificate of liability insurance from the contractor's insurer, and see our hiring checklist.
