Attic decontamination in Brossard
Rodents, droppings, mould: we remove contaminated insulation, sanitize and re-insulate — for a healthy attic in Brossard.
When to decontaminate your attic in Brossard
Persistent odours, rodent noises, droppings, stained insulation or visible mould: when an attic is contaminated, adding insulation on top solves nothing — you need to remove, sanitize, then re-insulate. It's common in Montérégie's housing stock, especially homes that have had wildlife intrusions.
Our procedure — compliant and complete
Contained and protected work area, industrial extraction of soiled insulation by vacuum truck, sanitizing and disinfection of surfaces, sealing of entry points, then re-insulation to R-50/R-60 — all compliant with RBQ, CNESST and IQAQ, with before/after photos on file.
What it costs
Depending on the extent of contamination and the area, attic decontamination generally runs between $800 and $5,000 before re-insulation (see our 2026 price guide). The calculator gives you a starting point in 2 minutes, and the exact assessment is confirmed on-site, free of charge.

How much does attic decontamination cost in Brossard?
Generally between $800 and $5,000 before re-insulation, depending on extent and area. The exact assessment is done on-site, free of charge, before any commitment.
How do I know if my attic is contaminated?
Persistent odours, noises in the attic, visible droppings, stained or sagging insulation, unexplained allergies. When in doubt, send us photos — we'll tell you honestly whether decontamination is needed.
Do you re-insulate after decontamination?
Yes — that's the core of what we do. After sanitizing, we re-insulate to R-50/R-60 with new insulation, and the project may qualify for LogisVert/Rénoclimat grants.
