What to know about Air sealing
Air sealing is the work of closing the unintended openings that let conditioned air out of a house and outdoor air in. It is separate from insulation, which slows heat conduction but does little to stop air movement, and separate from weatherstripping, which seals the moving joints at doors and operable windows. What air sealing targets is the fixed, hidden leakage: top plates, chases, penetrations, band joists, dropped soffits and the junctions where one part of the building meets another.

- Access to the space
- Ventilation changes
How to choose insulation contractors in Worcester
- Choose a contractor who talks about air sealing and ventilation, not only adding more insulation.
- Ask them to check the attic or walls for moisture, mould, old wiring or insulation that may contain asbestos before starting.
- Get a written quote that states the type of insulation, the areas covered and the target insulation level.
- For spray foam, ask about their training, curing time and when it's safe to be back in the home.
- Consider an energy audit before and after the work to see where heat is being lost.
Questions to ask insulation contractors before you hire
- What type of insulation do you recommend for this area, and why?
- Will you seal air leaks before insulating?
- How will you keep the attic properly ventilated?
- What will you do if you find old insulation that may contain asbestos, mould or old wiring?
- For spray foam, how long do we need to stay out of the house?
- Does this work need a permit or an inspection?
Air sealing permits in Worcester
Some air sealing work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.

Common air sealing questions
Is LokalMatch free for homeowners?
Yes. You never pay LokalMatch to request quotes or talk to pros. Professionals pay a fee to connect with homeowners whose projects fit their business.
How many pros will contact me?

Do I have to hire someone?
No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
