West Nile Plumbing & Drainage
WNPD · New Westminster & the Lower Mainland

Water in the crawl space? Start with the source.

Pooling water and persistent dampness deserve a closer look. Contact WNPD about drainage concerns beneath your home, including the timing of water entry and any known sump or perimeter system.

Tell us your location and symptoms. Availability and scope are confirmed directly.

Standing water and dampness are different clues

Tell us whether there is standing water, wet soil, a visible pipe leak or a musty smell. Note whether the condition follows rain or household water use. A smell alone cannot identify a drainage failure; moisture can have more than one source.

Prepare information without entering an unsafe space

Share the access location, approximate clearance if known, and photos you can take safely from outside the opening. Mention visible wiring, damaged supports, contamination or other access concerns. Do not crawl into standing water to photograph or unplug equipment.

Look at the whole drainage route

An investigation may consider water arriving from outside, accessible plumbing, perimeter drainage, and any sump or discharge arrangement. A pump is only part of a system: the source of water and a suitable discharge route matter too. Ask what has been checked before choosing a repair.

Separate drainage work from moisture restoration

Removing a drainage restriction does not automatically dry insulation, repair timber or resolve ventilation concerns. If those issues are present, ask which trade or restoration professional should assess them. Do not cover up wet materials simply to conceal the symptom.

Before authorizing work

Ask for the identified concern, access requirements, inspection limits and proposed next step. For an existing sump, provide the model and maintenance history if available without entering the space. Keep a record of the work and discuss what to monitor after the next rainfall.

Common questions

Will a new sump pump solve every wet crawl space?

No. The source, drainage route, discharge and any other moisture issues should be considered before selecting equipment.

What should I send WNPD first?

Your city and neighbourhood, whether water is rising now, when it appears, and a description of the access. Share photos only when you can take them safely.

Tell us where the water is showing up.

Include your neighbourhood, affected fixtures or area, when it started, and whether water is rising now.
