Mould Prevention in Attics, Basements and Garages

Attics

• Investigate roof leaks, ice dams, bathroom or dryer exhaust that terminates in the attic, and blocked ventilation.
• Look for damp insulation, staining on sheathing, frost, condensation and musty odour.
• Use qualified professionals for roof, insulation and ventilation corrections.

Basements

• Maintain grading, downspouts, window wells, sump systems and plumbing.
• Keep cardboard and absorbent contents off concrete floors and away from exterior walls.
• Address recurring condensation, seepage or high humidity rather than relying only on surface cleaning.
• Dry water losses promptly and inspect hidden lower-wall cavities.

Garages

• Control snow and rain brought in by vehicles and maintain drainage where provided.
• Do not store wet materials, firewood or cardboard against walls.
• Inspect roof edges, overhead doors, plumbing and shared walls for leaks or condensation.
• Maintain safe ventilation and avoid introducing uncontrolled moisture into the home.

When professional assessment is appropriate

• The moisture source is not clear or keeps returning.
• Mould affects a large area, hidden cavity, HVAC system or multiple rooms.
• Sewage, contaminated water, fire residue or significant structural damage is involved.
• Occupants have health concerns or the property is a healthcare, childcare or other sensitive environment.
