Toilet installation in Newmarket.

Replacing an old toilet, installing the one you bought, or adding a toilet where there was none. Standard, comfort-height and wall-hung, installed by licensed plumbers and leak tested before we leave.

How does a toilet installation work?

We confirm the rough-in matches your toilet, remove the old unit, check the flange and shut-off, set the new toilet level on a fresh seal and leak test it. A straight replacement is one short visit; a new toilet where there was none is a rough-in job.

A new toilet uses a fraction of the water an old one does and solves the running, rocking and weak-flush problems in one go. Seal Plumbing replaces toilets across Newmarket, from a straight swap in the same spot to a wall-hung unit on a new carrier in a renovation. If you have already bought the fixture, send us the model: we confirm the rough-in distance matches before we come and tell you before we start if anything will not fit.

Adding a toilet where there was none is a rough-in job we do all the time: a new powder room under the stairs, a basement bathroom, an ensuite in an addition. That means drain, vent and supply planned to the Ontario Plumbing Code, and a sewage ejector where the fixture sits below the main drain. Pete and Joseph quote it in writing first.

Wall-hung toilets need a carrier set solidly inside the wall before drywall and tile. We rough in the carrier during your renovation so the finished wall is clean and the unit is serviceable later. Our toilet installation guide covers what to look for when choosing one.

What does toilet installation cost in Newmarket?

Toilet installation in Newmarket is quoted before we start, same-day for a straight replacement. The price depends on whether it is a swap in the same spot, a wall-hung unit on a carrier, or a brand-new toilet that needs drain, vent and supply roughed in.

Same-spot replacementThe low end: remove, reset, connect, test, old toilet taken away.
Wall-hung carrierThe carrier goes inside the wall during a renovation, before tile.
New locationDrain, vent and supply roughed in, with an ejector where the toilet sits below the main drain.

Every job is quoted before work starts, in writing for anything beyond a small repair, and the quote is the number that counts. Same-day quotes on most small jobs; larger projects within 24 to 48 hours of a site visit.
