What to check around a Port Coquitlam home
Check 1
Observe the site during rain
Photograph ponding, overflowing gutters, full window wells, and water moving toward the foundation. These observations help distinguish an exterior drainage problem from a plumbing or isolated crack issue.
Check 2
Keep public inlets visible
The City asks residents to clear leaves, snow, and ice from nearby catch basins where it is safe to do so. A blocked street inlet can contribute to localized ponding even when private drainage is working.
Check 3
Identify nearby watercourses
Before grading, trenching, or changing a drainage route near a creek, ditch, or other surface drainage feature, check whether a Watercourse Development Permit is required.
Local drainage and permit context
Port Coquitlam warns that heavy rainfall can produce localized flooding, ponding, and elevated drainage channels. Emergency surface water and repeat below-grade seepage may be related, but they should be documented and diagnosed separately.
Municipal guidance changes and a rule for new construction may not apply to a maintenance repair. Confirm the address, scope, permits, and inspections directly with the municipality before work begins.

Repair approaches to compare
The right scope should follow the diagnosed source. Compare proposals by the water path they address, the drainage outlet they rely on, required inspections, restoration exclusions, maintenance, and written warranty terms.
Wet basement repair
A problem-first repair path that starts with the water entry mechanism instead of jumping straight to a single product or method.
Basement waterproofing
A broad term for controlling recurring water intrusion with interior, exterior, or combined drainage and sealing methods.
Foundation crack repair
Focused repair for leaking or stable foundation cracks, with the method chosen according to whether the crack is only leaking or also moving.
Exterior foundation waterproofing
Excavation-based waterproofing that stops water before it reaches the wall by rebuilding the foundation’s outside protection layer.
Interior drainage systems
A perimeter collection system that catches seepage inside the basement and moves it to a sump or discharge point.
Crawlspace encapsulation
A moisture-control approach for crawlspaces that combines sealing, drainage, and humidity management instead of leaving the space open to soil moisture.
