What to know about Spray foam insulation
Spray polyurethane foam is mixed on site from two liquid components and sprayed onto rim joists, foundation walls, roof decks and framed walls, where it expands and hardens in place. Because it fills every crack and joint it touches, it does two jobs at once: it insulates, and it stops air from leaking through the assembly. That makes it especially useful in the awkward, leaky parts of a Canadian house where batts or boards are hard to fit well.

- Removal of old insulation
- Air sealing work
- Access to the space
- Ventilation changes
How to choose spray foam contractors in Longueuil
- 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 spray foam 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?
Spray foam insulation permits in Quebec

Common spray foam 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.
