Cleaning up water is treating the symptom. Waterproofing is the cure. London Restoration Pros fixes leaky basements at the source — cracks, drainage, pumps, and grading.
That white chalky staining on the concrete (efflorescence), the musty smell every July, the hairline crack that darkens after rain — these are early chapters of a story that ends with a flooded basement or a mold problem if nothing changes. London-area homes fight two persistent enemies: clay soil that swells with water and pushes against foundation walls, and freeze-thaw cycles that work every crack a little wider each winter.
The good news: basement water problems are extremely fixable, and the fix is usually far more targeted (and cheaper) than homeowners fear.
Poured-concrete cracks sealed from the inside with polyurethane or epoxy injection — a permanent fix for the most common single leak source, typically done in a couple of hours.
For chronic seepage on block foundations: an interior weeping tile system along the footing, directing water to a sump — the approach that works when exterior excavation isn't practical.
New installs, replacements, and — critically — battery backups. Pumps fail during storms, which is exactly when the power flickers. The best dollar-for-dollar flood insurance a London basement can buy.
Excavation, membrane, and new weeping tile — the gold standard for chronic problems, especially older homes whose original clay weeping tile collapsed decades ago.
Stops municipal sewer surcharge from becoming your problem. Pairs with any sewage backup history.
Sometimes the fix is embarrassingly simple: extensions moving roof water 6 feet from the foundation, and regrading soil that settled toward the house over 30 years.
Most homes need one targeted fix, not the whole menu. Assessments are free, written, and option-based: the must-do fix, the should-do upgrade, and the nice-to-have — priced separately.

1. Dry and clean up properly — fast, before mold. Flooded basement cleanup →
2. Check for mold if the water sat or the space was finished. Mold removal →
3. Waterproof so there's no round two.
We handle all three, which means nothing falls between contractors. A century home in Wortley Village with a stone foundation, a 1965 side-split in Strathroy with clay weeping tile, and a 2010 two-storey in north London with a tired builder-grade sump need three different solutions — the assessment tells you which one is yours.
Crack injection: typically $400–$800 per crack. Sump pump install with battery backup: $1,500–$3,500. Interior drainage systems: usually $3,000–$10,000 depending on footage. Full exterior excavation: $10,000–$25,000+. Most homes need one targeted fix, not the whole menu.
Exterior stops water from touching the wall (best, most invasive, most expensive). Interior manages water that gets in (very effective, far less disruptive). The right answer depends on foundation type, landscaping, and budget — a good assessment gives you both options priced.
A dry, warrantied basement removes the single biggest red flag in a home inspection. In practice it protects value more than it adds it — and it makes finished-basement investments safe to make.
Warranty terms depend on the solution installed — crack injections and drainage systems typically carry multi-year to transferable warranties. Ask during the assessment; get it in writing.
Free written assessments across London and 70 km around it — with options priced, not a one-size-fits-all pitch.
