Basements are a common source of stress for Vancouver homeowners — especially with the city’s constant rainfall and clay-heavy soil.
At Aftermath Contracting, we’ve seen it all: from tiny cracks that let in a trickle to full-blown floods after a winter storm.
Why Basements Leak
The biggest culprits are often small, invisible issues that worsen over time:
Cracks in the foundation caused by soil pressure or aging concrete.
Poor exterior drainage where downspouts or grading push water toward the home.
Clogged perimeter drains, which are common in older Burnaby and North Vancouver homes.
Improper sealing during initial construction — especially in homes built before modern waterproofing standards.
Warning Signs to Watch For
Musty smell or damp air
Small puddles after rain
Efflorescence (white powdery deposits on walls)
Peeling paint or rust on basement fixtures
How to Fix It
Apply interior sealants for minor moisture issues.
Reseal foundation cracks with hydraulic cement.
Install a sump pump for high water tables.
Get professional exterior waterproofing for long-term protection.
