Increased Savings, Increased Comfort...

Insulation and air sealing decrease your energy use, saves you money, and increases your home comfort year-round, keeping you cooler in the summer and warmer in the winter. Take advantage of  75-100% off approved insulation improvements in addition to having air leaks sealed in drafty areas of your home at no-cost.

How to get started:

  1. Call Cape Light Compact at 1-800-797-6699 to set up your Home Energy Assessment or sign up online here.
  2. During your Assessment, you’ll receive a complete attic-to-basement evaluation of how you’re currently using energy, and a custom home energy report outlining recommended energy efficiency improvements. Plus, energy-saving products like LEDs, advanced power strips, and programmable thermostats will be installed at no cost as needed during the assessment.
  3. If an Energy Specialist completed your Assessment, he/she will be able to coordinate insulation and air sealing services with an Independent Installation Contractor (IIC), or you can select one of our participating IICs on your own by using our Find a Contractor tool.

You may also apply for 0% financing through the Mass Save HEAT Loan on eligible insulation upgrades.

Completion of weatherization is required for a number of other rebates including, windows, moderate-income heating and cooling, and whole home heat pump rebates. Customers who complete weatherization recommendations made during an energy assessment prior to a partial home heat pump installation may be eligible for a $500 bonus. Ask your energy specialist for more details. 

Have a chimney? We also have a $35 incentive on chimney balloons, a small inflatable device that can help stop drafts. Download the chimney balloon rebate form here.
