AIR SEALING · MA & RI

Stop paying to heat the attic.

Insulation works better when uncontrolled air leaks are sealed first. We look for the gaps that let warm air escape and make rooms uncomfortable.

No sales pitch, no obligation. We look, we measure, we tell you what we’d do.

What we look for

Real conditions are easier to understand when you can see them. We take photos, explain what is happening, and show the clean result we are working toward.

Before insulation work
BEFORE

Find the real problem

Low depth, gaps, old material, dust, moisture, access issues, or air leakage can all make the space perform worse than it should.

After insulation work
AFTER

Install the right fix

The right scope can improve comfort, reduce heat loss, and leave the work area cleaner than we found it.

Three ways we solve it

We do not force one product onto every job. Here is how this service usually fits into the bigger insulation plan.

Top plates and penetrations

Seal common attic leakage points around wiring, plumbing, and framing.

BEST FIT

BEST FIT

Insulation after sealing

Questions customers ask

Still not sure? Call and ask. We’d rather explain the right option than sell a job you don’t need.

How do I know if this is the right service?

The inspection is designed to show what is actually happening and whether this service, another insulation option, or a smaller fix makes more sense.

How long does the work take?

Many residential jobs can be completed in a day, but timing depends on access, size, removal needs, material, and whether spray foam is involved.

Will you show photos?

Yes. The goal is to show photos, explain the scope, and give you a written next step before you commit.

Do you handle rebates or programs?

Residential pages do not promise Mass Save. Commercial, church, and nonprofit eligibility must be verified before any incentive claim is made.
