Mould Removal in Toronto & the GTA
Attic and wall mould removed at the source, followed by the ventilation work, air sealing and insulation repair that stop it coming back.
What we see in these homes
- A musty smell upstairs or near the attic hatch
- Dark staining on attic sheathing or roof trusses
- Insulation that is damp, matted or discoloured
- Recurring window condensation through the winter
How the job runs
Inspection and cause
We identify the moisture source before treating anything — treatment without the cause always fails.
Containment
The work area is isolated so spores are not spread through the house.
Treatment
Professional-grade products applied to affected sheathing, framing and surfaces.
Repair and prevent
Ventilation corrected, air leaks sealed, and contaminated insulation replaced.
Diagnosing the cause before treating
| What we see | What it points to |
|---|---|
| Frost on nails and sheathing | Warm humid air leaking up from the house |
| Growth concentrated above a bathroom | Fan venting into the attic |
| Growth along the eaves | Blocked soffit ventilation |
| Damp, matted insulation | Ongoing condensation — the material comes out |
Treatment without correcting the source fails within a season or two. This is the order we work in.
What we install
Professional antimicrobial treatments for wood and sheathing
HEPA-filtered extraction for contaminated insulation
Baffles, vents and air sealing to correct the underlying cause
Questions about this service
Do we have to leave the house?
Usually not. The work area is contained and the extraction vents directly outside.
Will the mould come back?
Not if the moisture source is corrected — which is why we never treat without fixing ventilation and air leaks.
Is the insulation salvageable?
Contaminated insulation comes out. We quote the replacement at the same time so there is no second visit.
