Sealing air leaks in your home is a simple, cost-effective way to lower heating and cooling costs, increase comfort, and create a healthier indoor environment.

Heat can find its way out of the home through a wide variety of gaps, cracks, and holes in all parts of the house. With our blower door test and home energy audit, we can quantify how much air is leaking out of your house and pinpoint the leaks.

From the attic to the basement, Mainline Home Energy Services can locate and seal air leaks all throughout the home.

Dr. Energy Saver & Mainline Air Sealing

Air sealing and insulation go hand-in-hand

It’s important to note that neither insulation or air sealing alone are enough to reduce heat flow. Air sealing should always be done before insulation is installed.

As part of our air sealing strategy, we typically air seal the attic first since this is where the most significant leakage occurs. The basement and crawl space areas are our second priority. Air sealing these spaces eliminates a major source of cold air infiltration.

Air sealing and insulation upgrades from Mainline Home Energy Services can possibly cut your heating and cooling costs in half. Learn more about our blower door test or give us a call to schedule an estimate for an air sealing and insulation upgrade!

Start saving energy and money with an air-sealing upgrade

Mainline Home Energy Services technicians can perform a second blower door test when the air sealing work is done. The lower leakage rating confirms that you have a more airtight home, with enhanced energy performance, greater comfort, and lasting savings on your heating and cooling bills.
