What We’re all About

Our Mission

To consistently exceed the customers' expectations by providing the highest quality products and services in the weatherization industry.

“We recently had an energy audit by Chad Farnum and it was a real eye-opener. Having lived in the same house for over 30 years, I thought I knew where all the leaks would be. We’re so pleased with the savings and the comfort!”

— David and Michelle from Marlboro, VT

What We Achieve

New England’s weather requires buildings to have a higher standard for insulation than many other parts of the country. With decades of building and contracting experience, we saw firsthand how poorly fiberglass insulation performs—leading to lost money, less comfort and wasted energy resources.

We work with homeowners, businesses and institutions to:

  • Assess your building’s insulation needs through thorough diagnostic testing

  • Create the most cost-effective and non-invasive plan to increase your energy efficiency

  • Find all available cost saving incentives and grants to reduce your costs

  • Help you enjoy your home or place of business more than you ever have

Building Performance Institute certified and focused exclusively on insulating homes and businesses, we are the most trusted name in insulation. Call us today to start saving money.
