Signs you need mould remediation
- A musty smell that gets stronger after rain or snowmelt
- Black or green spots at the floor–wall joint, around windows or on cold exterior walls
- Peeling paint or bubbling drywall low on basement walls
- Growth on stored cardboard, wood shelving or attic sheathing
- A past leak or flood that wasn't professionally dried
Our mould remediation process
- Assess. We do a visual inspection, moisture mapping and thermal imaging to find the extent and the moisture source.
- Contain. We put up poly barriers and negative-air machines with HEPA filtration to isolate the work area.
- Remove. We take out contaminated porous materials (drywall, insulation, carpet) and bag them inside the containment.
- Clean. We HEPA-vacuum and clean structural surfaces, then apply antimicrobial treatment.
- Dry. We dehumidify to target moisture levels so the mould doesn't return.
- Verify. We do a post-remediation check (third-party clearance testing can be arranged if you want it).
We stop at remediation. Once the area is verified, it's ready for the contractor of your choice.
Where mould hides in Ottawa homes
Older brick and stone homes in the Glebe and Centretown often have damp foundations. Finished basements in Barrhaven, Kanata and Orléans can hide growth behind drywall after a sump or window-well leak. Attics anywhere in the city can develop it from winter condensation and ice dams. Crawl spaces → crawl space and attic mould guide.
What not to do
- Don't spray bleach on drywall or wood. It doesn't fix porous materials.
- Don't dry-brush or sand mould, because it spreads spores.
- Don't run the HVAC fan if growth is near the ducts or the furnace.
- Don't cover it with paint.

FAQ
Do you take small mould jobs?
Yes. We welcome every genuine mould job, small ones included.
Is black mould dangerous?
Mould can affect indoor air quality and health, especially for people with asthma, allergies or weakened immune systems. Any visible growth over a few square feet should be handled professionally with containment.
Are you certified?
Yes. Our crews are PMII certified for mould remediation.
How long does mould remediation take?
Small areas often take a day or two. Larger basements take longer, depending on the materials and the drying.
Will the mould come back?
Not if the moisture source is fixed and the area is dried. We identify the source as part of every job.
Do you rebuild after removal?
No. We do remediation only, and the area is left clean and verified for your contractor.
Can you test the air after?
We do a post-remediation check, and independent third-party clearance testing can be arranged.
