Seal and insulate

Seal & Insulate: $3,000 rebate

In most houses, air leaks add up to the equivalent of a fully open window. Leaky ducts in attics and crawlspaces can account for 20% or more of your home’s energy losses. Air-sealing and adding insulation are often the most cost-effective ways to improve your home’s energy efficiency.

  • Air-seal your home to SMUD program standards, including attic floor. 
  • Install and seal new ductwork to SMUD program standards.
  • Insulate your attic and deep-bury ductwork to SMUD program standards.
