Find your leak

Six places water gets into a basement

Each one has a different repair. Select the number that matches what you see.

BasementCity sewerWindow wellSaturated soil123456
1

The whole wall is damp

What you see
Damp patches, white powder or peeling paint along one full side of the basement.
Why it happens
The soil outside is saturated — often because a downspout empties beside the wall or the old weeping tile is clogged — and water is soaking through the concrete or block.
The repair: Exterior waterproofing
2

Water at a basement window

What you see
Water marks below a window, or a window well that fills up in rain.
Why it happens
The well has no drain, or its drain is blocked with leaves and soil, so it fills like a bucket and overflows through the window frame.
The repair: Window well drain
3

One wet line on the wall

What you see
A vertical or diagonal crack that darkens or drips when it rains.
Why it happens
Poured concrete shrinks as it cures and cracks. The crack runs through the full thickness of the wall, so it gives water a direct path in.
The repair: Crack injection
4

Water where the wall meets the floor

What you see
A wet strip or puddles along the base of the wall after heavy rain or a thaw.
Why it happens
The floor slab and the wall are separate pours with a joint between them. When water builds up beside the footing, that joint is where it enters.
The repair: Interior drainage system
5

Water rising through the slab

What you see
Damp spots or water in the middle of the floor, often through hairline floor cracks.
Why it happens
The water table under the house has risen above the underside of the slab. The water is pushed up from below, not in from the side.
The repair: Sump pump
6

Water coming out of the floor drain

What you see
Dirty water from the floor drain, shower or basement toilet during a storm.
Why it happens
The city sewer is overloaded and is flowing backwards into the pipe that serves your house.
The repair: Backwater valve

Services

What we do

Six repairs cover almost every wet basement in Etobicoke. Most houses need one or two of them.

Painted concrete block basement wall of the kind an interior drainage system is installed along

Interior waterproofing

A drain under the floor edge collects the water and a sump pump sends it outside.

Inside or outside

The two main systems, compared

Both dry out a basement. They work from opposite sides of the wall.

Wall membraneNew concrete over the drainPipe in clear stoneDischarge lineSump pit and pump

Interior waterproofing

A strip of floor is cut along the wall, a perforated pipe is laid in clear stone beside the footing, a membrane on the wall guides seepage down to the pipe, and the pipe runs to a sump pump.

The result

A dry basement is usable floor space

How it works

Four steps from first call to dry basement

  1. Assessment

    We visit, check inside and outside, and tell you where the water is getting in.

  2. Written quote

    You receive the scope of work, the materials and the price in writing.

  3. The work

    The crew protects floors and landscaping, completes the repair and cleans up.

  4. Test and paperwork

    The repair is tested with water, and you get the invoice the City needs for the subsidy.

Where we work

Every neighbourhood in Etobicoke

Etobicoke sits between the Humber River and Etobicoke Creek, with Mimico Creek running through the middle and Lake Ontario along the south. Houses near those valleys and the lakeshore sit closer to the water table, and much of the housing dates from the 1940s to the 1960s, when foundation drains were clay tile.

City of Toronto subsidy

Toronto pays back up to 80% of a backwater valve and sump pump

The Basement Flooding Protection Subsidy Program covers a backwater valve, a sump pump and a battery backup, up to set maximums per property. We explain the conditions and give you the documents the application asks for.

How the subsidy works

Questions

Asked before almost every job

How much does basement waterproofing cost in Etobicoke?

The price depends on four things: how many metres of wall are treated, how deep the footing is, whether a machine can reach the wall, and what has to be removed and put back — a deck, interlock or a finished basement wall. That is why we look at the house first and then give you the scope and the price in writing.

Does the City of Toronto help pay for any of this?

Yes. The Basement Flooding Protection Subsidy Program pays back up to 80% of the invoiced cost of a backwater valve, a sump pump and a battery backup, within set maximums. The subsidy page lists the amounts and the conditions.

Interior or exterior waterproofing — which one do I need?

Exterior waterproofing stops water before it enters the wall, so it suits a wall that is wet across its whole height or a house with a failed weeping tile. Interior waterproofing collects water at the footing and pumps it out, so it suits water at the floor-wall joint and walls that cannot be reached from outside because of a driveway, a deck or a neighbouring house.

Water came up through the floor drain during a storm. Is that a waterproofing problem?

No — that is a sewer backup. During heavy rain the city sewer fills and pushes water back up the pipe that serves your house. The fix is a backwater valve on that pipe, not a membrane or a drain.

Can the work be done in winter?

Interior drainage, crack injection, sump pumps and backwater valves are installed inside the house, so they are done year-round. Exterior excavation depends on frost in the ground and is usually scheduled from spring to late autumn.
