What to know about Air sealing
Air sealing closes the cracks, gaps and holes that let heated air escape from a house and cold outdoor air leak in. In a Canadian winter, warm air rises and pushes out near the top of the house, at the attic hatch, around ceiling fixtures and along the tops of walls, while cold air is drawn in low, at the rim joist, around basement windows and through service openings. The result is drafts, cold floors, frost in the attic and a heating system that works harder than it should.

How to choose insulation contractors in Kingston
- 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 Ontario
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?
We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.
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.
