Re-Energize your home - The first step in our process is a Home Energy Audit performed by an expert in building science. Based on your concerns and goals, your home consultant will provide a complete home analysis that includes customized solutions so that you can pick the projects that give you the most bang for your buck.

Some of the most common problems that we fix are high energy bills, drafty homes, uneven heat distribution (rooms that are cold in the winter or hot in the summer), leaky ductwork, and unhealthy indoor air quality - a service especially beneficial for children and those with allergies or asthma.
