What Is Air Sealing
Air sealing is the process of locating and closing gaps in a home’s building envelope where indoor air escapes and outdoor air enters. Even small openings can affect heating and cooling performance, particularly during winter months.
Common leak points include:
-
Attic penetrations and recessed lighting
-
Gaps around ductwork and plumbing
-
Basement rim joists
-
Window and door framing
-
Utility openings
Sealing these areas improves temperature consistency and reduces unnecessary strain on HVAC systems.
Why Air Leakage Matters in Massachusetts Homes
New England homes experience significant seasonal temperature swings. During winter, warm air rises and escapes through attic gaps. This creates negative pressure that pulls cold air in from lower levels.
This process increases heating demand and can contribute to drafts and uneven temperatures.
Air sealing addresses these pressure imbalances before adding insulation, making it a foundational step in improving overall energy performance.
What to Expect During an Air Sealing Project
Air sealing typically begins with a Mass Save® home energy assessment. During this visit, a certified contractor evaluates insulation levels and identifies leakage areas.
If the home qualifies, certain air sealing improvements may be completed as part of the program.
Work may include:
-
Sealing attic bypasses
-
Applying foam sealant around penetrations
-
Installing weatherstripping
-
Addressing rim joist leakage
The scope depends on the condition of the home.
Air Sealing and Insulation
Air sealing and insulation work together. Insulation slows heat transfer, while air sealing prevents air movement. Performing insulation without addressing air leaks reduces effectiveness.
For this reason, air sealing is often completed before insulation upgrades.

I never write reviews, ever. I had to write this one because I was honestly blown away by this company.
It started with Sean coming over for what I assumed was … Read More just a standard quick inspection. He didn't just look around, he actually installed 6 new thermostats in my house right then and there, completely for free (to me). That set the tone for the whole experience, and the crew that came later really amazed me also.
Jack and Jacob contacted me when they were on the way, showed up exactly on time, and worked harder than I expected was possible. They had to fully insulate the house (attic, 2nd floor, 1st floor, basement, and an outside crawl space). The weather was miserable. It was absolutely freezing outside, and then it started pouring rain. Jack and Jacob were up on ladders, freezing and soaking wet, and they just kept working without a single complaint. They honestly could have taken the easy route and drilled through my inner walls to get the job done fast. Instead, they chose to do it the hard way to make sure they didn't destroy the inside of my house. They took the time to remove the vinyl siding, drill from the outside in, and then put the siding back on perfectly. You just do not find people who care that much about your home anymore.
Jack was incredible at keeping me fully updated through the entire process so I never had to guess what was going on. It turned into a massive project. What was supposed to be a 2-day job turned into 4 days of them working morning till night. They stayed until it was done right, they were extremely polite and knowledgeable the whole time, and there was zero upcharge for the extra days of labor.
Jack, Jacob, and Sean are the absolute stars of the show here. These guys are who you want to work on your home, period. -
Joe Frasso did a very good job with analyzing my home and assessing the needs to make iy more efficient. He was very pleasant, informative, and helpful with talking … Read More about the needs and options. -
I had a wonderful experience. Joe was a pleasure to deal with. He was extremely thorough in his assessment and communicated everything to me on how to make our home … Read More more efficient and carbon neutral, we are going to move forward with insulation and are very intrigued in moving off of oil now that he explained to us the turn key program! Highly recommend colt home services!
