Mould Remediation Cost in Vancouver: When and How to Address It
Mould in Vancouver Homes: A Common Problem
Vancouver’s wet climate — over 1,100mm of rain annually and sustained high humidity — creates ideal conditions for mould growth. Pre-1990 homes with inadequate insulation and vapour barriers are particularly vulnerable. Understanding mould risks, testing, and remediation costs protects both health and renovation investment.
Common Mould Locations in Vancouver Homes
- Bathroom walls and ceiling (poor ventilation)
- Basement walls and floor (moisture infiltration)
- Attic (roof or soffit leaks, inadequate ventilation)
- Behind exterior walls (failed weather barrier)
- Under sinks (plumbing leaks)
Mould Testing Costs
- Air quality sampling (by certified inspector): $400–$900
- Tape/swab sampling: $200–$500
- Full home mould inspection: $600–$1,500
Mould Remediation Costs in Vancouver
| Scope | Cost Range |
|---|---|
| Bathroom mould removal (minor, 1 room) | $1,000–$3,500 |
| Basement mould remediation | $3,000–$10,000 |
| Attic mould remediation | $3,500–$12,000 |
| Wall cavity mould (open walls required) | $5,000–$20,000 |
| Extensive/full home remediation | $15,000–$50,000+ |
Addressing Root Cause
Mould remediation without fixing the moisture source is a temporary solution — it will return. Root causes must be addressed: bathroom exhaust fan upgrade, basement waterproofing, exterior weather barrier repair, or HVAC/humidity control improvements. Budget for root cause fix on top of remediation.
