Mould Remediation
Mould Removal & Remediation in Toronto & the GTA
Mould (or mold) comes back unless the moisture behind it is fixed. TGV Construction Group finds the source, removes the mould safely inside containment and repairs the area - across Toronto and the GTA from our base in Concord.
01
Inspection & Moisture Source
Mould needs moisture. Before anything is removed we find where the water comes from - a leak, a crack, condensation or past flooding - with moisture meters and thermal imaging.

02
Containment & Safe Removal
We follow a safe and hygienic approach: the work area is sealed off with containment and air filtration, so the rest of the house is protected and you can usually stay at home.
Mouldy drywall, insulation and other porous materials are removed; the remaining surfaces are cleaned and treated. Painting over mould only hides it until it comes back through the paint.

03
Fix the Cause & Repair
Remediation lasts only if the moisture source is fixed and the space stays dry, so source repair is built into our process. Then we rebuild the opened walls, ceilings and floors.

- Structural drying
- Waterproofing
- Drywall and finishes
04
Asbestos Before Renovation
Older homes can contain asbestos in insulation, plaster, tiles and pipe wrap. Ontario Regulation 278/05 requires trained and qualified workers and proper procedures for asbestos work, and testing before demolition is standard practice.
Before we open walls in an older home we arrange testing, and any asbestos is handled under the regulation.

- Work under O. Reg. 278/05
- Regulated disposal
- Clearance documentation

What to do right now

Frequently asked questions
How much does mould removal cost?

Can I stay in my home during mould remediation?
Usually yes, with proper containment protecting the rest of the house. For heavy contamination, we advise on precautions when we scope the job.
Will mould come back after remediation?
Not if the moisture source is fixed and the space is kept dry. That is why source repair is built into the process.
Is mould remediation covered by insurance?
It depends on the cause. Sudden water damage that led to mould is often covered; long-term seepage or humidity problems usually are not.
Is mould the same as mold?
Yes. Mould is the Canadian and British spelling, mold the American one - it is the same problem and the same work.
