In plain terms
What air sealing an existing home is
Air sealing finds and closes the gaps and cracks where outside air leaks into your home and conditioned air leaks out — around attic hatches, top plates, and pipe or wiring penetrations.
Caulking and weather-stripping are the two simplest and most common air sealing techniques — inexpensive materials and a straightforward install. Air sealing alone does not replace proper insulation, which slows heat moving through the building envelope — the two work together.

Common questions
Air Sealing questions, answered
A few of the questions homeowners ask most about this service. The full list lives on our FAQ page.
What is the difference between air sealing and insulation?
Insulation slows heat moving through the attic and ceiling. Air sealing closes the gaps where conditioned air escapes and outside air leaks in. They solve different problems and work best together — sealing the leaks first means the insulation you add actually does its job.
“Our 50-year-old house needed help, and we were so glad to find an honest company that knew exactly what to do. Now we are sealed up tight, with rebates on top of it.”
What does air sealing change in my home?
Air sealing is one of the most affordable efficiency upgrades — inexpensive materials and a straightforward install. The change most homeowners feel is comfort: the drafts in the rooms you use every day drop as soon as the work is done. How much it moves a utility bill varies from home to home, so we focus on the comfort and durability you can actually count on.
“They were fair and very professional and completed the work in a timely manner. Since having the work done, our house is much warmer — we have not even turned on our bedroom heater.”
Where does a house leak air the most?
The biggest leaks are usually hidden — attic hatches, the top plates where walls meet the attic, and the gaps around plumbing, wiring, and recessed lights. We walk the home to find where conditioned air is actually escaping rather than guessing from the obvious spots.
“They came and inspected the attic and were very thorough about what needed to be done. They listened to our needs and did exactly what we asked for, at a very reasonable price.”
