BC Home Leak Proofing Guide: Protect Your Property from Water Damage

Water damage is the most common home insurance claim in BC. The average claim costs $10,000-$30,000, and many homeowners face premium increases after a claim. Most water damage is preventable with regular maintenance and early detection. This guide covers everything BC homeowners need to know.

Know your shut-off valve location. Every adult should know where the main water shut-off is and how to use it. In an emergency, every minute of flowing water causes exponential damage. Test the valve annually.

Monitor your water bill monthly. Your bill is your best early warning system. Track monthly consumption and investigate unexplained increases of 30% or more. A running toilet can waste 200+ litres daily without making sound.

Inspect visible plumbing annually. Check under sinks for leaks. Inspect toilet supply lines. Check water heater connections. Replace washing machine hoses every 3-5 years with braided stainless steel.

Maintain your roof and gutters. Clean gutters twice per year. Inspect roof after storms. Check flashings around chimneys and vents. Trim tree branches overhanging the roof. Remove moss carefully.

Manage exterior grading. Soil should slope away from foundation. Extend downspouts 6+ feet from foundation. Check window well covers. Ensure driveway grading directs water away.

Maintain your building envelope. Inspect exterior caulking annually around windows and doors. Re-caulk as needed. Check for cracked siding or masonry. Paint exterior wood to prevent rot.

Schedule professional inspections. A thermal imaging inspection every 2-3 years establishes a baseline and detects developing issues. Pre-purchase moisture inspections are essential. LeakInspections.ca — a division of Anyleak.ca and Leak.ca. Call 604-239-9934.
