Sump Pump Installation
in Mission, BC
Mission sits on the north bank of the Fraser River directly opposite Abbotsford, with the older parts of the community perched on the hillside above the river and newer development extending north up the Dewdney Trunk Road corridor. The hillside setting gives many Mission homes good natural drainage by gravity — a significant advantage compared to the flat bottomland communities — but the steep terrain creates its own challenges, including lateral water pressure against uphill foundation walls and erosion that can undercut perimeter drainage.
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 Mission — What We See Here
The historic downtown area of Mission has residential housing dating from the late 1800s through the mid-20th century, including some of the oldest surviving homes in the Fraser Valley. Crawlspaces in these properties have had a very long time to accumulate problems, and the original structural wood — where it survives — is often dense, slow-growth timber that has proven remarkably durable despite decades of inadequate moisture management. Even so, prolonged moisture exposure eventually catches up with any wood species, and we often find targeted areas of significant rot alongside sections of original framing that are still structurally sound.
Mission's location at the head of the navigable Fraser means it experiences some of the highest spring freshet water levels in the region during snowmelt years. Properties near the river and in the lower Mission areas should have sump systems that are sized to handle freshet conditions, not just typical winter rainfall — a meaningful distinction in terms of pump capacity specification.
