Blown cellulose & fibreglass insulation
Economical and effective. Blown with precision into the attic, cellulose blocks heat and noise — the best return on investment for most homes.
Construction Devtech insulates, caulks and decontaminates Quebec homes to stop heat loss — often in a single day, with no dust and no hassle.
Sub-par insulation and air leaks let that heat escape — mostly through the roof. Better insulation and caulking recover that heat, cut your carbon footprint, and lower your bill, winter after winter.
Our experts assess your needs, propose cost-effective solutions and carry out the work to building-code standards — quickly and meticulously.

For healthy air. Removal of vermiculite — potentially asbestos-contaminated — and other contaminants and allergens, to clean your home’s air.
Lasting weather-tightness. Our team perfects every joint for clean, durable seals — without damaging your surfaces — to stop infiltration at the source.
Our insulation and caulking services are eligible for the Quebec programs in effect today. Work performed under our RBQ licence — an eligibility condition.
Grant for improved insulation (attic, walls, roof) and up to $800 for air-sealing. An energy assessment by a certified advisor is required before work begins.
Support for combined roof-insulation and caulking work. Apply online within 9 months of completion. Stackable with Rénoclimat.
Rénoclimat and LogisVert stack when components are complementary. Modest-income households may also use Éconologis (free, October–March: caulking, weatherstripping, advice).
Amounts are indicative, determined by your home’s energy assessment; programs change — confirm conditions on the official Rénoclimat and Hydro-Québec sites. Note: no company is mandated to solicit on behalf of Rénoclimat; the assessment is done by an independent certified advisor, and we carry out the eligible work.
