Drainage Solutions
in New Westminster, BC
New Westminster is British Columbia's oldest incorporated city and has one of the highest concentrations of pre-war residential housing in Metro Vancouver. The Queen's Park neighbourhood in particular has exceptional heritage housing stock — Victorian and Edwardian homes on full perimeter foundations, many with crawlspaces that were original construction in the early 1900s. When we work in these homes, we are often the fourth or fifth generation of tradespeople to address crawlspace conditions, and the accumulated history of previous repairs — good and bad — is part of what we need to understand before planning a current project.
Drainage problems in crawlspaces have two distinct origins: water that arrives from outside (surface runoff, failed exterior drainage, high water table) and water that condenses from the air inside the crawlspace onto cooler surfaces. The solutions for each are different, and correctly diagnosing which problem you have — or which combination — is the critical first step. Applying interior drainage solutions to an exterior water problem provides partial relief at best; addressing the exterior source is far more effective and usually less disruptive.
Interior drainage systems — perimeter drain tile installed inside the crawlspace along the base of the stem wall — are the right solution when exterior work is impractical (due to finished landscaping, hardscaping, or very tight site conditions) or when the primary issue is groundwater rising from below rather than surface water entering through the wall. Interior drain tile channels water to a sump pit where a pump removes it. This approach does not stop water from entering the foundation, but it manages it effectively once it does.

About New Westminster — What We See Here
New Westminster's hillside topography, with much of the residential development on slopes above the Fraser River, creates drainage challenges similar to other hillside communities in the region. The older storm drainage infrastructure in established neighbourhoods has limited capacity by modern standards, and during heavy rainfall events, surface water can overwhelm curb drains and flow toward residential foundations. The clay-over-till soil profile common on the slopes holds water at the surface and creates hydrostatic pressure against foundation walls.
The city's older homes frequently have original fir framing that, when dry, is dense and hard — actually more resistant to rot than modern hem-fir in many cases. However, the moisture conditions in unencapsulated crawlspaces over the decades can compromise even dense old-growth fir over time. We pay particular attention to the condition of original sill plates, which are often the first structural element to show moisture damage because they sit closest to the ground. Where sill plates are solid, the adjacent framing is usually in better shape than the exterior appearance of the crawlspace might suggest.
