Mould removal & remediation in Waterloo

Signs you have a mould problem

• A musty smell in the basement, closet or attic
• Black, green or white spots on drywall, wood or caulking
• Peeling paint, warped baseboards or stained ceilings
• Mould coming back after you cleaned it
• Allergy-like symptoms that get better when you leave the house

Why mould shows up in Waterloo homes: rentals, condos and finished basements

Student and multi-unit rentals near the universities often have small bathrooms, poor ventilation and lots of people, so bathroom and window mould is common every winter. In newer neighbourhoods it's more often a finished basement after a sump pump failure or a slow leak behind drywall. In condo units, mould usually starts from a leak from the unit above or a failed window seal.

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 Waterloo, 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.
