It’s Easy to Weatherize Your Home and Save Money

Consider insulation and air sealing.

Add insulation to your home and decrease your energy use while increasing your comfort. Plus, you may qualify for instant incentives:

  • No-cost targeted air sealing of leaks in drafty areas of your home, which may include your attic, basement, living spaces, and attic ductwork
  • Based on your income, 75 percent off approved insulation improvements (up to $2,000) or 90 percent off approved insulation improvements (up to $3,000)
  • 75 percent off approved duct insulation (up to $1,000)


Save On Your Monthly Bills

Keep conditioned air inside your home, preventing it from escaping through your home’s structure. The Environmental Protection Agency (EPA) estimates Massachusetts homeowners can save an average of 18 percent on heating and cooling costs by air sealing their homes and adding insulation. Weatherizing your home not only makes your home warmer in the winter, but also cooler in the summer.

Ducts that move air to and from a forced air furnace, central air conditioner, or heat pump are often big energy wasters. Sealing and insulating ducts can improve the efficiency of your heating and cooling system by as much as 20 percent, and sometimes much more.

Mass Save® offers standardized pricing for program-approved weatherization improvements for your convenience. All participating Home Performance Contractors and Independent Installation Contractors offer the same pricing for insulation and air sealing.
