Step by step

How Insulation installation works

  1. A contractor inspects the home and may run a quick energy assessment.

  2. You get a written quote by area and R-value target.

  3. Existing gaps are air-sealed first.

  4. Insulation is installed in the attic, walls, or crawl space.

  5. You claim the 25C credit and submit any rebate paperwork.
