Insulation and Air Sealing

Save 20% or more on your annual heating and cooling bills.

When installed together, air sealing and insulation are the most cost effective way to save energy, reduce your heating and cooling bills, and make your home more comfortable.

Air leaks add up to energy loss

Did you know that the average home has enough air leakage to add up to a two-foot-square hole? That is like leaving a small window open 24 hours a day. This is usually the biggest source of energy loss in a home. Sealing holes, cracks, chases and penetrations is one of the quickest ways to make your home more comfortable and efficient.

The energy audit identifies areas of your home that are in need of air sealing (before you insulate make sure that your home is properly air sealed).

A blower door test, performed during a home energy audit, locates air leaks. Blower door tests are performed by participating DC Home Performance contractors before and after air sealing to measure the effectiveness of their work.

Insulation plus Air Sealing equals comfort, winter and summer

Many homes are missing a simple but important piece of the energy efficiency equation: proper insulation. Many older homes have less insulation than homes built today, but even adding insulation to a newer home can pay for itself within a few years. Insulating your attic/ceiling and floors keeps you comfortable throughout the year, reduces outside noise, prevents ice dams in the winter, saves energy, and reduces your heating and cooling costs.

A DC Home Performance contractor will include an insulation check as a routine part of a whole-house energy audit, and provide recommendations for adding insulation. Find a participating DC Home Performance contractor to help improve the efficiency of your home with air sealing and insulation.
