Basement Waterproofing in Langley, BC

Crack injection and interior drainage work generally don't require permits. Structural repairs and excavation affecting the building envelope may require permits from the Township of Langley or City of Langley depending on your address and scope. We confirm permit requirements as part of the quote so there are no surprises.

Three local factors: Fraser Valley clay-rich soils that expand when saturated and shrink in dry summers, heavy October-to-April rainfall that loads soil against foundation walls, and the age of the housing stock — much of Langley, from Brookswood's 1970s lots to Walnut Grove's 1990s subdivisions, has perimeter drains near or past their service life. Add freeze-thaw cycles and you get the vertical shrinkage cracks and seepage we see in most inspections.

Yes — we cover all of Langley including Walnut Grove, Willoughby, Brookswood, Murrayville, Fort Langley, and Aldergrove, plus Surrey, Abbotsford, Maple Ridge, and White Rock. Call to confirm availability for your address.

Interior waterproofing manages water after it reaches the foundation wall, capturing it at the base and redirecting it to a sump pump. It's faster and less disruptive, with no excavation. Exterior waterproofing stops water from reaching the wall at all by excavating to the footing and applying a membrane. It costs more and takes longer but addresses the source rather than the symptom.

Interior waterproofing typically runs $70–$150 per linear foot, with most homes landing in the $3,000–$10,000 range. Exterior waterproofing runs $150–$250+ per linear foot, with a full perimeter job often landing between $10,000 and $35,000+. We walk the full perimeter during the free inspection and give you a written number broken out by section.

For most Langley basements with moderate seepage, interior systems are a fine tradeoff for the lower cost and faster timeline. If you're dealing with a genuinely high water table, repeated hydrostatic pressure, or a wall that needs fresh damp-proofing, exterior work is the more durable long-term fix. We tell you plainly which situation you're in during the free inspection.

For a basement with recurring water problems, yes. Untreated seepage leads to mould, damaged flooring and drywall, and structural concrete damage over time, all of which cost more to fix than waterproofing would have. Interior systems, the more affordable option, typically pay for themselves the first time they prevent a flooded basement. Not every basement needs the full exterior treatment though. A free inspection tells you whether you're dealing with a minor issue or one that's actively getting worse.
