What this job involves

When water climbs out of a basement floor grate, the grate is almost never to blame. It is simply the lowest hole in the building, so anything choking the building drain or the lateral to the street shows itself there first. The colour of the water, its smell, and whether it rises when someone upstairs runs a tap tell us a great deal before the cleanout plug is even loosened.

How the job goes

Ask the household to stop running water so the level stops climbing.
Locate the main cleanout and crack the plug slowly to read the level behind it.
Feed a heavy cable streetward until the line lets go.
Run the camera through the newly opened pipe to look for roots, breaks or a dip.
Disinfect around the grate and refill its trap with clean water.

Warning signs on your pipes

Dark water collects around the grate after a load of laundry.
The basement toilet bubbles while the washer pumps out.
A sewer smell hangs in the basement after a downpour.
The grate gurgles with nothing running upstairs.
A grey tide ring circles the drain on the concrete.

From the job notes

On many of Oakville’s older streets the lateral is vitrified clay or cast iron, and street maples have spent decades threading fine roots into its joints.

On many of Oakville’s older streets the lateral is vitrified clay or cast iron, and street maples have spent decades threading fine roots into its joints. After a backup, the camera tells us whether we met a one-time plug or a lateral that wants repair. North of Upper Middle Road the laterals are mostly PVC and far less tempting to roots, so a backup up there more often points to wipes or fat.

If your floods arrive with thunderstorms rather than with laundry day, the municipal sewer may be surcharging, and that is when a backwater valve earns a conversation. Halton Region has run a flood-prevention subsidy that helped households with that cost; check what the Region offers right now before counting on it.

Questions we hear

Is a backed-up floor drain urgent?

If the water is sewage and still rising, yes: stop using water and call. Clear rainwater is less pressing but still deserves a same-day look.

Whose pipe is it out to the road?

Under Halton’s usual arrangement, the stretch inside your property line is the owner’s to maintain. Ask the Region to confirm for your lot.
