Drainage service covers everything that keeps water moving away from a house instead of pooling against it: grading the yard, installing or repairing weeping tile, French drains, catch basins, sump pumps, downspout extensions, and window well drains. In a city like Richmond Hill, where clay-heavy soil and spring runoff put steady pressure on foundations, this work overlaps with waterproofing and often gets called in after a wet basement, a soggy backyard corner, or a municipal inspection flags a grading issue. We've reviewed 5 businesses offering drainage service in the area to help you narrow down who's actually equipped for the job.
What a good drainage contractor does differently
Drainage problems are easy to patch and hard to fix properly, so the gap between a mediocre job and a good one shows up years later, not on day one. Before hiring, look for a few things: a contractor who inspects the actual water path (roof to downspout to grade to foundation) rather than just digging a trench where water happens to sit; clear talk about pipe type, slope, and where the water discharges to (storm sewer, dry well, or daylight); permits pulled when the work ties into municipal storm infrastructure; and a written scope that separates excavation, materials, and backfill/restoration costs. Photos of finished trenches before backfill are a good sign, since that's the part you can't check later.
How our scoring works
Our ranking weighs review consistency, how contractors respond to complaints, the range of drainage work they actually handle (surface grading versus interior weeping tile versus sump systems), and how transparent they are about pricing and warranty terms. We don't accept payment for placement. For the full breakdown of criteria and weighting, see our methodology page.
