Weeping Tile & Drainage Systems
Most wet basements start with poor drainage. We fix the way water moves around your house — so it's carried away instead of pooling against the foundation.
Window well, weeping tile and surface drainage that moves water away from your foundation.
Before water gets into a basement, it has to get to the foundation and sit there. Collapsed or clogged weeping tile, a window well with no drain, downspouts dumping at the wall, grading that slopes toward the house, a sewer that backs up in a storm — these are the causes behind most of the leaks we're called to. Fix the drainage and many basements simply stop leaking.
We replace failed weeping tile, install window well drains and covers, fit backwater valves to stop sewer backup, correct grading and manage downspout and sump discharge so water ends up well away from the house. Several of these items qualify for municipal subsidy programs, and we'll help you claim what applies.

How we fix drainage
Inspect and find the cause
We look at how water reaches your foundation — roof runoff, grading, window wells, the condition of the existing weeping tile — and identify what's actually failing rather than guessing.
Replace collapsed or clogged weeping tile
Old clay or crushed tile is dug out and replaced with new perforated pipe in filter sock, set on grade in clear gravel so it drains freely for decades.
Window well drains and covers
Each well gets a drain tied into the weeping tile so it can't fill up and spill over the sill, plus a cover to keep leaves and debris out.
Backwater valve
A backwater valve on the sanitary line stops municipal sewer backup from coming up your floor drain during a storm — one of the most common and most expensive kinds of basement flooding.
Grading and downspouts
We regrade so the ground falls away from the house and extend or redirect downspouts and sump discharge so roof water never lands against the foundation.

Weeping Tile & Drainage Systems FAQs
What is weeping tile and how do I know if mine has failed?
Weeping tile is the perforated pipe at the base of your foundation that collects groundwater and carries it to a sump or storm connection. Signs it has failed: water at the wall-floor joint, a sump that never runs even in heavy rain, or a house old enough to have clay tile, which collapses and silts up over time.
Will a backwater valve stop my basement flooding?
If your flooding comes up through the floor drain during storms, yes — that's sewer backup and a backwater valve is the fix. If water comes through the walls or at the floor joint, the cause is groundwater and the answer is waterproofing or drainage. We tell you which it is.
Are these subsidized?
Often. Backwater valves, sump pumps and downspout disconnection are the items most municipalities subsidize; Toronto's program covers up to $6,650 across eligible items. We'll confirm what your city offers and give you the documentation.
