Attic insulation, decontamination and roof replacement in Thetford Mines and the surrounding area.
A historic mining town, Thetford preserves entire streets of wooden workers' homes. Sturdy but energy-hungry, they respond very well to old-insulation removal followed by blowing to R-50 and rigorous sealing.
Your insulation work in Thetford Mines may qualify for Hydro-Québec's LogisVert grant (up to $1,500, with no prior energy assessment) or the Rénoclimat program. We check your eligibility and file the applications for you. Details in our grants guide.

Up to $1,500 with Hydro-Québec's LogisVert, and we handle the applications for you, start to finish.
Hydro-Québec's LogisVert program is the most popular insulation grant: up to $1,500 for owners of a house heated mainly with electricity, when the work combines roof insulation and air sealing, with no energy assessment required beforehand. At Toiture & Isolation Provinciale we don't just tell you about it: we fill out and submit the application on your behalf, from eligibility check to confirmation. You receive your reference number by email, zero paperwork on your end.
The Quebec government's Rénoclimat program pays up to $1,500 for the roof only if the insulation in place is R-12 or less ($750 or $250 above that). It requires an energy assessment before and after the work, by a recognized advisor. Our detailed reports are compliant and documented, and we support you at every step until approval.
Amounts, conditions, which one to pick: see our insulation grants guide.
Flexible financing with 3 months with no payments and no interest, so you can start your project right away. The grant arrives after the work. Subject to credit approval.
