Fall 2026 Leak Prevention Guide for BC Properties: Prepare for the Rainy Season

October marks the beginning of BC's rainy season, when properties across the province face their greatest water intrusion risk. With Environment Canada predicting an above-average precipitation winter for 2026-2027, now is the time to prepare. At LeakInspections.ca, a division of Anyleak.ca and Leak.ca, our technicians are already seeing increased call volumes for roof leaks and envelope moisture issues. This guide covers the essential steps every BC property owner should take before the rains arrive.

Clean all gutters and downspouts thoroughly. This is the single most important fall maintenance task. Clogged gutters cause water to overflow behind fascia boards and into the building envelope. Ensure downspouts extend at least 6 feet from the foundation. Consider installing gutter guards if you have trees near your home.

Inspect your roof for damage. Look for lifted or missing shingles, deteriorated flashing around chimneys and vents, and signs of moss or algae growth. Schedule a professional roof inspection if your roof is over 10 years old or if you notice any issues. A drone thermal roof inspection can identify hidden moisture issues before they cause interior damage.

Check your building envelope. Inspect exterior caulking around windows, doors, and siding penetrations. Re-caulk any areas where sealant has cracked or pulled away. Pay special attention to south and west-facing walls that receive the most wind-driven rain. For strata buildings, schedule a building envelope assessment before winter.

Test your sump pump. Pour water into the sump pit to verify the pump activates and discharges properly. Check the discharge line for blockages. Consider installing a battery backup sump pump for power outage protection—BC's winter storms frequently cause power outages.

Prepare pipes for freezing. Disconnect outdoor garden hoses and shut off exterior faucets. Insulate pipes in unheated areas such as crawlspaces, attics, and garages. Know the location of your main water shut-off valve. During cold snaps, let faucets drip slightly to prevent freezing.

Monitor your water bill. A sudden increase in your water bill during winter when outdoor water use is minimal is a strong indicator of a hidden leak. If your bill increases unexpectedly, check your meter and call 604-239-9934 for professional detection.

Schedule your annual leak detection inspection. An annual thermal imaging survey costs $500-$1,000 for most homes and provides a comprehensive assessment of your property's moisture condition. For strata buildings, an annual survey protects all owners and supports insurance renewals. Call 604-239-9934 to schedule your inspection before the rains arrive.
