Improvements which are eligible include:

  • Attic, wall, floor or crawlspace and rim joist insulation
  • Air sealing measures such as weather stripping, caulking, interior storm windows If a homeowner does the work themselves, they should save all receipts for materials associated with the installation. A dollar value for self-labor is not eligible for a rebate.
