Ashton Thermal performs building analysis and weatherization services for buildings in north-western Vermont. As a Home Performance with ENERGY STAR contractor, we use state-of-the-art diagnostic tools to analyze the building envelope for air and moisture intrusion, indoor air quality, occupant safety, and energy efficiency. Using our findings, we can quickly and accurately determine where and how to properly seal a structure, thereby making it a more comfortable, healthy, energy-efficient and structurally sound living or working environment.

We look at a building as being more than just the sum of its parts; it is a system that requires each component to perform properly. If one part fails to do its job, it can compromise the entire system. When we survey a building, we look at all of the components that affect the integrity of the structure and the health of the occupants.

After having thoroughly evaluated your home, or other building, we then make recommendations for improvements. These will often include adding insulation, air sealing, ventilation and other measures designed to make your building function harmoniously.

Ashton Thermal is not only a building consultant; we are a building performance contractor. This means that we can fix the problems for you. One of the benefits of working with us is that you have the assurance of quality control provided by Home Performance with ENERGY STAR, as monitored by Efficiency Vermont. We submit each of our completed jobs to them for review and follow-up, so you will have the peace of mind of knowing that we have performed our services effectively.

Home Performance with ENERGY STAR: A drafty home, rooms that are too hot or too cold, and high energy bills are all common issues for homeowners. Installing a new heating or air conditioning system, buying replacement windows, or adding more insulation may fix part of the problem. But the way to better results is through an integrated "whole-house" approach that looks at your house as a system. Home Performance with ENERGY STAR, a national program from the U.S. EPA and U.S. DOE, offers a comprehensive, whole-house approach to improving energy efficiency and comfort at home, while helping to protect the environment.
