06
One contractor, from the air test to the last coat of paint.
Mold decontamination
Sealed containment, negative pressure, HEPA filtration, removal of contaminated materials and antimicrobial treatment.
Water damage response
Structural drying, humidity control and fixing the cause — otherwise the mold comes back, guaranteed.
Controlled demolition
Safe removal of drywall, insulation and affected materials — without spreading spores through the rest of the building.
Reconstruction
Drywall, paint, flooring, trim: we rebuild to new, not just to bare studs. One contract, one crew.
Prevention & ventilation
Fixing moisture sources, ventilating crawl spaces and attics, encapsulation and humidity monitoring.
OUR PROCESS — IICRC S520 COMPLIANT
Five steps, documented start to finish.
- 01
Inspection & diagnosis
On-site visit, moisture readings, thermal imaging, air tests if needed. We find the cause, not just the stain.
- 02
Written protocol
S520-compliant work plan and a fixed, itemized written quote. No surprises mid-job.
- 03
Containment
Sealed zone, negative pressure and HEPA filtration. Spores stay in the work area — not in your air.
- 04
Decontamination
Removal of affected materials, HEPA scrubbing and vacuuming, antimicrobial treatment of remaining surfaces.
- 05
Clearance & rebuild
Clearance test, final photo + lab report, then a full rebuild by the same crew.
Every step is photographed and logged in the final report — for your insurer, and for resale.
WHY US
Born in water damage. Built to rebuild.
-
We rebuild too. One contract from diagnosis to paint — no juggling three different contractors.

-
Everything documented. Before/during/after photos, signed protocols and independent lab results.
-
Claims made simple. We build the file and deal directly with your Quebec insurer.

FAQ
The questions we get every week.
Can I remove mold myself with bleach?+
On a small non-porous surface (ceramic, metal, under 1 sq ft), yes. On drywall, wood or insulation, bleach whitens the surface without reaching the roots — and it all comes back with humidity. Beyond 10 sq ft, professional containment is recommended so spores don't spread.
Is it covered by my home insurance?+
Often, when the cause is a sudden and accidental loss: water damage, sewer backup, burst pipe. Rarely when it's chronic untreated humidity. We document the cause from the first inspection and build the file directly with your insurer.
Do we have to leave the house during the work?+
In most cases, no: the work zone is sealed and kept under negative pressure, and contaminated air is HEPA-filtered before it leaves. The written protocol confirms it based on the scope and your building's ventilation.
How long does the work take?+
Small area: 1 to 2 days. Medium area: 3 to 5 days. Major contamination with rebuild: 1 to 3 weeks. The schedule is part of the written protocol, before work starts.
How do I know if it's "black mold"?+
Color alone doesn't tell you: only a lab analysis identifies the species (Stachybotrys or otherwise). That's exactly what our surface tests do. Either way, the safe-removal protocol is the same — all visible mold has to go, not just the black kind.
Do you offer a guarantee?+
Yes. A clearance test at the end of the job and a written guarantee — valid as long as the moisture cause is fixed. That's why we fix it ourselves rather than decontaminating over an active problem.
