What to know about Insulation contractors
An insulation contractor works on the building envelope: the walls, roof, foundation and floors that separate heated rooms from the outdoors. In a Canadian winter, heat escapes through every part of that shell, by conduction through thin or missing insulation and by warm air leaking out through cracks and gaps. The contractor's job is to slow both, choosing the right material for each part of the house and installing it without trapping moisture.

Insulation costs in Saint-Lambert

How to choose insulation contractors in Saint-Lambert
- 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?
Insulation permits in Quebec
Some insulation 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.
Licensing in Quebec
General contracting and renovation
Anyone who does residential renovation work for you must hold an RBQ licence, and that licence must include the subclasses required for the work you are hiring them for.

Common insulation 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.
