Adding adequate insulation is one of the most cost-effective home improvements that you can do.
Products that air seal (reduce air leaks) can also qualify, as long as they come with a Manufacturers Certification Statement, including:
- Weather stripping
- Spray foam in a can, designed to air seal
- Caulk designed to air seal
- House wrap
Tax Credit does NOT include installation costs. But, you can install the insulation/home sealing yourself and get the credit.
