Weatherization - Capital Good Fund

by Capital Good Fund

In partnership with local utilities, we are thrilled to offer the DoubleGreen Loan. Ranging from $500 to $25,000, this interest-free loan pays for measures that make your home more energy-efficient and safe. In fact, you can get a DoubleGreen loan for a variety of upgrades (usually as a package of measures), including:

  • Wall insulation and replacement windows
  • Duct sealing
  • Removal of knob-and-tube wiring
  • High-efficiency heating and cooling equipment
  • Any other measure that National Grid has deemed eligible for the program. A full list can be found here.

Designed to serve the needs of moderate-to-middle-income homeowners with less-than-perfect credit, the loan is paid back in monthly installments over two to seven years. And because you don’t have to pay interest, the loan is extremely affordable.

You may also receive a free energy-efficiency assessment at this link.
