Hire a Certified Contractor – All weatherization projects should be completed by a Building Performance Institute (BPI) certified contractor. In order to qualify for rebates, your BPI contractor must ALSO be approved by your state’s efficiency utility, either Efficiency Vermont or NHSaves.

“Weatherization” is a Whole Home Approach – only BPI contractors are trained to take a whole-home approach to improve your home’s efficiency, comfort, health, and safety. For example, your BPI contractor can:

  • Test your combustion appliances to ensure toxic gases are vented properly
  • Ensure you have plenty of ventilation and fresh air even after your air sealing improvements are completed
  • Reduce moisture, mold, and drafts that contribute to poor air quality
  • Help eliminate ice dams and other issues related to heat loss
  • Help your home stay warmer in winter and cooler in summer
  • Reduce your energy costs, often significantly (average savings of 20-25%)

Your Weatherize Work Scope – Your BPI contractor will provide a home assessment and report containing many energy improvement opportunities. Common recommendations include air sealing and insulation, the two most cost-effective ways to increase comfort and reduce energy costs. If you can’t afford to tackle everything at once, your contractor can help you prioritize and choose a final work scope that meets your needs. Common priorities include air sealing and insulation in your attic and/or basement where the most heat loss and air leakage occurs. Your weatherization project will include:

  1. Energy efficiency improvements as agreed upon between you and your contractor
  2. Any necessary health and safety improvements
  3. All required tests/diagnostics to qualify you for any available rebates

Cost, Rebates, and Financing – Every home is different. Project cost may vary from less than $5,000 to more than $12,000 depending on your home and your budget. Rebates are available in New Hampshire and Vermont to help you pay for your weatherization project.

  • Vermont Rebates – Efficiency Vermont offers rebates for do-it-yourself weatherization, energy efficiency upgrades during remodeling, and comprehensive home weatherization.  
  • New Hampshire Rebates – NHSaves (a joint program of New Hampshire’s electric utilities) can cover a significant portion of your weatherization project cost. This program is available for homes using above a certain amount of energy per square foot (most homes in our region).

Low cost financing is also available. Many lenders offer secured and unsecured loans designed specifically for borrowers investing in home energy improvements.

Programs for Renters, Landlords, Small Businesses, and Nonprofits

Renters and Landlords

There are many low-cost improvements a renter can install to increase the efficiency of their home. Here is a guide for renters seeking to save energy and stay warm this winter, compiled by Efficiency Vermont.

For larger investments, renters will need to talk to their landlord. You will need to connect your landlord with NHSaves or Efficiency Vermont before any efficiency improvements are installed. They’ll be able to point your landlord to rebates and other attractive products that make it financially viable to increase the efficiency of your home.

Small Businesses and Nonprofits

NHSaves and Efficiency Vermont has a program for “small commercial” energy users that can help businesses and nonprofits reduce their heating and electricity use.

Visit Vital Communities’ Small Businesses Resource Page for a breakdown of available programs and next steps.
