Why mould shows up in Hamilton homes: century homes and escarpment water

Hamilton's lower city is full of century homes with stone foundations and old clay laterals; damp basements are common and mould follows. On the Mountain and in Stoney Creek it's more often finished basements after a sump or grading problem. Water from the escarpment in heavy storms can leave hidden moisture behind walls.

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 Hamilton, 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.
