Sump Pump Installation
in Metrotown, BC

The Metrotown area of Burnaby is predominantly high-density residential and commercial development, but the surrounding streets include significant numbers of older single-family homes and low-rise residential buildings on crawlspace foundations. These homes — largely from the 1950s through the 1970s — occupy the relatively flat terrain of central Burnaby, with clay-loam soils and drainage conditions typical of the region.

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.
