Basement Leak Repair

How We Find and Fix Basement Leaks

Our certified technicians start with a thorough visual inspection of your basement walls, floor, and cove joint (where the floor meets the wall). We identify the source β€” whether it's a crack, porous block, failed parging, or the cove joint β€” and recommend the right solution. We use high-grade epoxy or polyurethane injection for structural cracks, which expands to fill the crack completely and bonds to the concrete permanently.

How We Find and Fix Basement Leaks

Why Basement Leaks Get Worse Over Time

Water damage is progressive. A small crack that lets in a trickle during spring rains will grow year after year as freeze-thaw cycles expand the opening. Moisture leads to mould, damage to finishes, and deterioration of your foundation's structural integrity. Fixing it early is always cheaper and less disruptive than waiting.

Interior vs. Exterior Leak Repair

Interior repair methods (crack injection, drain tile systems) can be done without excavation and are ideal for most leaking basements. Exterior waterproofing is the most permanent solution β€” we excavate to the footing, apply a waterproof membrane, and install new weeping tile β€” but is reserved for severe cases or when full foundation protection is needed.

Frequently Asked Questions

How do I know if my basement leak needs crack injection or full waterproofing?
If the leak is coming through a single crack, injection is usually sufficient. If water is seeping through multiple areas, the cove joint, or through porous blocks, a drainage system may be more appropriate. We assess this during the free inspection.
How long does basement leak repair take?
Crack injection can typically be completed in a few hours. A full interior drain tile system usually takes 1–3 days depending on basement size.
Is there a warranty on basement leak repair?
Yes. ORS Plumbing provides a 25-year transferable warranty on all waterproofing work. If the repaired area leaks again, we come back at no charge.
Can you repair a basement leak in winter?
Yes. Interior crack injection can be performed year-round. Exterior excavation work is best done in above-freezing temperatures.
