Overview
Yard grading that sends water away from your house
Water follows the shape of the ground, so a yard that slopes the wrong way will keep pushing rain toward your basement however good the foundation is. Over decades, soil around a house settles, gardens get built up against the wall, and patios sink, and a lot that drained well when it was built can end up tilted back toward the house.
Fixing it starts with watching where the water actually goes. We look at downspout outlets, low spots that hold puddles a day after rain, patio and walk slopes, and the line between your yard and the neighbour's. Then we choose the simplest fix that solves it: extending or rerouting downspouts, rebuilding the grade so it falls away from the foundation, or adding a French drain or catch basin to carry water to a part of your lot where it can soak in or leave safely. Each option is explained on site, with what it costs and what it won't fix.

How we do it
Find the water
We check where water pools, where downspouts drain and which way the ground slopes.
Plan the fix
Regrading, downspout extensions, a French drain or a catch basin, or a mix, chosen for your lot.
Regrade
Clean fill and topsoil create a positive slope away from the foundation.
Drain and restore
Pipe in clear stone and filter fabric where needed, then sod or planting over the top.
Signs your yard has a drainage problem
- Water pooling next to the foundation after rain.
- A damp basement or musty smell after storms.
- Soil or a patio sloping toward the house.
- Downspouts dumping water right at the wall.
- Soggy lawn areas that never dry out.
Regrading, French drain or downspouts: which fix
Regrading fixes the most common problem: ground that slopes toward the house. Downspout extensions or buried lines move roof water away, often the cheapest fix of all. A French drain (perforated pipe in clear stone, wrapped in fabric) or a catch basin handles water that grading alone can't move. Many yards need a mix, and we explain the trade-offs on site.
Downspout rules in Toronto and Mississauga
Roof runoff is often the biggest single source of water near a foundation, and it's also the one cities regulate most. In Toronto, including Etobicoke, downspouts that drain into the sewer system must be disconnected under Municipal Code Chapter 681, unless the property qualifies for an exemption. Once disconnected, the water has to be directed onto your own lot, away from the house and without flowing onto a neighbour's property or creating an icy hazard on a sidewalk.
Mississauga's rules similarly expect property owners not to direct drainage onto neighbouring lots. In practice that means extension pipes or splash pads that carry water well clear of the wall, buried lines to a lower part of the yard, or a dry well where the soil allows. We plan the outlet location before cutting a downspout, so the water ends up somewhere legal and useful, not in the next basement over.

FAQ
Drainage and grading: what to ask first
How much does drainage and grading cost?
It depends on size, site and materials. Typical GTA projects run around $3,500–$9,000 typical grading and drainage fix. Yard French drains typically run $55–$95 per linear foot. We give you an exact written quote after a free site visit.
How do I know if my lot needs regrading?
Water pooling near the foundation, a damp basement after rain, or soil that slopes toward the house are the usual signs.
Will regrading fix a wet basement?
Often it helps a lot, because most basement water starts with soil sloping toward the house. Cracks in the foundation itself need a waterproofing contractor.
Where does the water go?
To a lower area of your own property, a dry well or the street side where allowed. Never onto a neighbour's lot.
How much slope should the ground have away from the house?
A steady fall away from the foundation for the first couple of metres, enough that water visibly runs off rather than sitting. We set the grade with a level on site, since how much is possible depends on doors, windows and neighbouring grades.
Can a French drain go in without ruining my lawn?
The trench disturbs a narrow strip, which we restore with topsoil and sod once the pipe and stone are in. The rest of the lawn stays untouched if access is planned well.
