Perimeter Drain Replacement in Langley, BC

Full perimeter drain (weeping tile) replacement on a typical Langley home runs $15,000–$30,000 depending on foundation depth, access, landscaping, and whether sections can be saved. Partial replacements and localized repairs cost considerably less. Homes built before the 1980s often have original clay or early PVC drains at the end of their service life — a camera inspection confirms condition before anyone recommends full replacement.

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.

A camera inspection down the existing line is what actually answers this, not a guess from the surface. If the failure is isolated to one section, a root intrusion at a joint or a silted-in low point, a partial replacement addresses it without disturbing the rest of the perimeter. If the original clay or early PVC tile has failed structurally throughout, full replacement is the honest recommendation. We run the camera inspection as part of every quote.

A full-perimeter job typically takes several days to a week, depending on landscaping, hardscaping, and how much of the foundation needs to be exposed. Partial replacements addressing one section take considerably less time.

It depends on what a camera inspection shows. If the failure is isolated, a root intrusion at one joint or a silted-in low point, a partial repair addresses it without disturbing the rest of the perimeter. If the original clay or early PVC tile has failed structurally throughout, repair isn't a real option and full replacement is the honest recommendation. We never quote full replacement without running the camera inspection first.
