We offer air sealing services for homes, multi-family buildings, and commercial buildings throughout the region. Air sealing and weatherizing your home is typically one of the best investments a homeowner or building owner can make for energy savings, energy bill savings, and reducing environmental impact.

What is Air Sealing?

Believe it or not, the majority of North American homes suffer from inadequate insulation, air leakage throughout the home, leaky duct systems, and other problems that

contribute to discomfort in the home and unnecessarily high energy bills. These problems often occur even in new, code-built homes. Weatherization and air sealing aim to remediate these problems throughout the house, leading to reduced energy bills, reduced environmental impact, and improved comfort throughout the year, through improvements such as air sealing, duct sealing, insulation, and more.

How Does it Work?

Our air sealing and weatherization upgrades begin with a home energy audit, during which we determine the most cost-effective upgrades for your home. Using tools such as a blower door and infrared thermal imager, we determine where insulation is lacking, where air leaks are occurring, and where other home energy problems may be originating. We then come up with a plan to solve these problems through low-cost, high-impact upgrades; implement the upgrades; and help you take advantage of any tax credits, rebates, incentives or financing options that may be available to help offset the cost of the work.

  • I must admit that when I completed the LIPA energy audit and found out that an outside company will be doing the audit, I was skeptical. But, as an energy conscious consumer I kept an open mind. My doubts dissapeared from the first contact with your company.
