Insulation & Air Sealing

Keep Your Home Comfortable All Year Long

Insulating and sealing are necessary for your home.

In Vermont, the weather changes faster than we can keep up with it. From freezing winds to humid summer days, your home works hard to keep you comfortable. If it’s under-insulated or has drafty windows and doors, those temperature swings can drive up your energy bills and leave a bigger environmental impact than you realize. Homes built before 1990 are especially likely to be losing energy without the homeowners even knowing it.

Start With an Energy Audit

The smartest first step is a home energy audit. Thanks to Efficiency Vermont, you have access to expert guidance and financial incentives that make improving your home easier and more affordable. An audit identifies where your home is leaking energy and shows you the most effective upgrades to boost comfort and efficiency.

Air Sealing: Your First Line of Defense

Before adding insulation, air sealing is essential. Reducing drafts is one of the quickest and most cost-effective ways to cut heating and cooling costs. Simple fixes like weatherstripping and caulking can make a big impact by tightening up gaps around doors, windows, and other openings.

Insulation: Boost Comfort and Savings

Anywhere your home touches the outdoors should be insulated. More insulation usually means better performance. Common options include:

  • Fiberglass, affordable and easy to install

  • Spray Foam, excellent at insulating and sealing, though more expensive

  • Cellulose, blown into attics and walls for great coverage and value

Weatherization: The Whole-Home Approach

When all systems work together, your home becomes safer, more efficient, and more comfortable. Air sealing, insulation, moisture control, and ventilation each play a role in creating a healthier, more energy-efficient space.
