Working in Sherbrooke
Heat escaping through a thin attic melts roof snow from below and creates ice dams along the eaves, which can push water into ceilings. Ask for air sealing before new insulation goes in, and check that soffit vents stay open so the attic stays cold and dry.
Québec runs on aerospace, AI, hydroelectric infrastructure, and a deep manufacturing base, with cold continental winters that demand audit-ready exclusion and HVAC programs.

Questions
Do you take attic, spray foam and home insulation jobs in Sherbrooke?
Yes. Requests from Sherbrooke, Laval, Terrebonne, Mascouche and the rest of Quebec are handled the same way. Use the quote form on this page, or email [email protected] with the service, the address and the timing.
There is grey-brown pebble insulation in my attic. Is that a problem?
That is probably vermiculite, and some vermiculite contains asbestos. Do not disturb it or store things on it. It needs to be tested, and if it contains asbestos it has to be removed by a qualified abatement contractor before any insulation work goes ahead. Mention it in your email so the right specialist reviews your request.
Are there rebates for insulation?
Sometimes. Utilities, provinces, states and federal programs in Canada and the US have offered rebates or tax credits for insulation and air sealing, but they change often and many require an energy assessment before and after the work. Check what is available in your area before you sign, and ask for an itemized quote you can submit.
How long does an insulation job take?
An attic top-up on a typical house is often done in a day. Spray foam in a basement usually takes a day or two, plus time for the foam to cure before anyone goes back in. Dense-packing walls or removing old insulation takes longer. The written quote should give the timeline and any time you need to stay out of the house.
How do I get a quote?
Email us your city, the type of house, the areas you want insulated and what you are noticing, such as cold rooms, drafts or ice dams. A specialist who works in your area follows up to look at the house and give you a written quote. Requesting a quote is free and there is no obligation to go ahead.
How much insulation should my attic have?
It depends on your climate. In most of Canada and the northern US, codes and energy programs point to roughly R-49 to R-60 in the attic, which works out to around 16 to 20 inches of blown-in insulation. Milder regions call for less. Many older houses have well under half that. The specialist measures what is there now and quotes the depth needed for your area.
