Why mould shows up in Toronto homes: older houses and busy condo towers
Much of Toronto is older housing: brick semis and bungalows with stone or block foundations, little insulation and basements that were finished long after they were built. Moisture wicks through the walls and gets trapped behind drywall and carpet. In condo towers we see a different pattern — window condensation, HVAC closets and slow leaks from the unit above.
How we remove mould
We start with a visual inspection and moisture mapping to find out how far the growth goes and where the water is coming from. The work area is sealed with plastic containment and kept under negative air pressure with HEPA air scrubbers, so spores don't spread to the rest of the home. Mouldy drywall, insulation and carpet are removed and bagged; wood and other structural materials are cleaned and treated. Then we dry the area, fix or recommend the fix for the moisture source, and rebuild.
Mould after water damage
Mould can start growing within 24 to 48 hours of a leak or flood. If you've had a burst pipe, a flooded basement or a sewer backup in Toronto, the fastest way to prevent mould is proper drying. See our water damage restoration service — the same crew handles both.
Cost and insurance
Cost depends on the size of the area, what materials are affected and how much has to be removed. Small, contained areas can be a few hundred dollars; full basements cost more. Insurance usually covers mould only when it comes from a sudden, covered water event, so we document the cause carefully. Read our mould remediation cost guide.

Toronto questions
How fast can you start mould removal in Toronto?
Toronto is our home base, so this is where we're fastest — typically well under an hour, 24/7.
Can I just clean mould with bleach?
Bleach can lighten surface stains but doesn't reach mould inside drywall or wood, and disturbing it can spread spores. Small spots can be cleaned; anything larger than about a square metre should be handled professionally.
Do you find where the moisture is coming from?
Yes. Mould always has a moisture source. We use moisture meters and thermal imaging to find it, and fix it or tell you exactly who should.
Is mould removal covered by insurance in Ontario?
Usually only when the mould comes from a sudden, covered water event such as a burst pipe. Long-term leaks and humidity are typically excluded. We document the cause so you can make the right claim.
Can I stay home during mould removal?
Most of the time, yes — the work area is sealed off. People with asthma or weakened immune systems may want to stay elsewhere during the removal.
