BC Home Buyer's Guide to Leak Detection

Guide for BC home buyers on pre-purchase leak inspections, red flags, and questions to ask before buying.

Most home buyers rely on standard visual-only inspections that cannot detect hidden moisture. This guide covers what BC buyers need to know about professional leak detection.

Pre-purchase moisture inspection is essential due diligence. Thermal imaging sees behind walls, moisture meters measure water content, and acoustic devices detect hidden plumbing leaks. 2-4 hours, $500-$1,000.

Red flags: fresh paint on ceilings or walls (may cover stains), new flooring over slab (may cover slab moisture), musty odours in basement, efflorescence on foundation, recent renovations around bathrooms or kitchen.

Review the property's leak history. Ask sellers directly about past leaks and repairs. For strata, obtain Form B. However, Form B only includes leaks reported to strata — private repairs may not be documented.
