Sump Pump Installation
in North Vancouver, BC
North Vancouver — comprising both the City and the District — sits on the steep south-facing slopes of the Coast Mountains, with residential development climbing from the waterfront up to the base of the ski hills at Grouse, Cypress, and Mount Seymour. This topographic setting creates dramatic drainage dynamics: rainfall that lands anywhere on the mountain eventually moves downhill, and the mosaic of residential lots on these slopes intercept and redirect that flow in unpredictable ways. Any home on a sloped lot in North Vancouver is managing not just the rainfall that lands on its own property but potentially a portion of what lands above it.
Surrey receives roughly 1,500 millimetres of precipitation annually, with the bulk of it arriving between October and March. For homes with crawlspaces, especially those in lower-lying areas of Newton, Bridgeview, or along the Serpentine and Nicomekl river floodplains, that volume of rainfall can overwhelm perimeter drainage and allow water to accumulate beneath the floor. A properly sized and installed sump pump is the most reliable mechanical defense against crawlspace flooding.
The choice of pump matters significantly. Sump pumps are rated by horsepower and gallons-per-hour capacity, and the right specification depends on the size of the drainage catchment area and how quickly water accumulates during peak events. Undersized pumps run continuously during heavy rain events, wear out faster, and may not keep pace with inflow. We size pumps to handle well above the expected worst-case scenario for a given home's drainage conditions.

About North Vancouver — What We See Here
The soils on the North Shore are predominantly shallow glacial till over bedrock, which drains quickly in some areas and slowly in others depending on the specific till composition and the presence of clay lenses. Because the till is relatively thin in many locations, the bedrock beneath it can channel water in directions that are difficult to anticipate without site-specific investigation. Homes that appear to have good drainage in dry periods can experience significant water intrusion during intense rainfall events as subsurface flow channels saturate and overflow.
Many of North Vancouver's established residential neighbourhoods — Lynn Valley, Moodyville, Upper Lonsdale — were built in the 1940s through the 1970s on crawlspace foundations, and the combination of steep site drainage, high annual precipitation, and aging construction has created persistent crawlspace moisture problems in a large proportion of this housing stock. The structural challenges are also more complex here because sloped lots sometimes result in one side of the crawlspace being at grade or above while the other is several feet below grade — requiring drainage solutions that address both the high and low sides of the foundation.
