Overview-Weatherization and Energy Efficiency Services

Capstone’s Weatherization programs:

  • Decrease a home’s energy consumption
  • Reduce a client’s carbon footprint
  • Save a household money
  • Show homeowner’s how they can save energy
  • Increase comfort
  • Increase property value

Capstone will perform energy savings renovations to stop heat from leaking out of the building and reducing the loss of heat through the walls and roofs of your home (also known as weatherization).  For income qualified individuals there is no charge through our Weatherization Assistance Program. If you do not qualify under the no-cost program, we can still help through EnergySmart, our award-winning social enterprise.  

Capstone is pleased to offer these services to all homes – from single family to multifamily households.  In certain instances we can do more – if you’re a landlord of a multifamily building (5 units and higher) planning to do major renovations and looking to save more than what standard Weatherization can offer our 3E Thermal program can help.

No-Cost Weatherization

Capstone provides weatherization services free of charge to central Vermonters who meet income and other qualifications. Trained professionals will review the problem areas in your home and identify the most cost-effective steps that can be taken to increase comfort, reduce heat loss, and ensure safety.

Energysmart of Vermont is a social enterprise of Capstone.  We are an energy renovation contracting company. We help building owners make their buildings more efficient and comfortable, and less expensive to heat and cool. Our vision is to make every one of Vermont's buildings energy-efficient.

How Do We Do It?

We conduct a comprehensive energy assessment; we recommend specific performance improvements; and we act as the contractors on the job, doing the necessary renovations. We've managed energy renovation projects on thousands of homes and businesses in Vermont, and we are the leading energy renovation contractor in the state.

The Greenest Building is the One that's Already There

Vermont has old housing stock that needs lots of work to make it cost-effective. We are up to the challenge of helping 100-year-old houses become energy-efficient. We want to help Vermonters manage their buildings effectively, so we are good stewards of resources for future generations.

100% of Profits to Community Action

Because we are a social enterprise of Capstone Community Action we have a unique mission. Our energy renovation work helps fund our parent organization's charitable endeavors.  We develop project estimates like any other construction company, and we pay our staff a fair wage for the demanding work they do. But instead of profits flowing back to the owners of the business, the profits from our contracting projects flow back into the community. They help fund the many other services that Capstone provides in our community.
