Sump Pump Installation
in Grandview Heights, BC

Grandview Heights is one of South Surrey's rapidly developing neighbourhoods, with a mix of townhouses, single-family homes, and multi-family residential projects built over the past decade. The newer construction in this area generally benefits from modern vapour barrier requirements in the BC Building Code, but "code minimum" is not always sufficient given local soil and drainage conditions — particularly as the neighbourhood transitions from a largely residential to a more urbanized form with increased impervious surfaces that alter surface water flow patterns.

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.
