Air Sealing Services in Massachusetts
Here is a quick list of the top energy efficiency services we offer:
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.
Mass Save Incentives
Massachusetts homeowners may qualify for incentives through the Mass Save program. Eligibility depends on utility participation and completion of a no-cost home energy assessment.
Incentives may include:
No-cost air sealing
Partial coverage for insulation upgrades
Access to HEAT Loan financing
Program details are subject to change. Eligibility is confirmed during the assessment process.
