Reasons to add a washroom downstairs
Finishing a basement, adding a secondary suite, or making a home work for a growing family are the usual reasons. Some homes already have a capped rough-in from the builder; we check that it is usable before relying on it.
On the job, step by step
We lay out fixtures, saw-cut and break the slab, and trench to the existing drain at proper slope. New drains connect with approved fittings and each fixture gets a trap and vent. Venting usually ties into an existing stack or runs up through a wall. After inspection, the trench is backfilled and concrete is poured. Supplies run overhead in the joists. If the fixtures sit below the sewer, an upflush or sewage ejector pump is used.

GTA houses and what they change
A backwater valve belongs in any basement with new fixtures, and many municipalities require one with new basement plumbing. Older homes with shallow footings need care when trenching nearby. Secondary suites have additional building code and fire separation rules.
Before you pick up the phone
Ask whether the quote includes the permit, concrete work and the backwater valve. Call (365) 387-8531.

Common questions
What is an upflush toilet?
A toilet with a macerating pump that lifts waste to a higher drain. Useful where trenching to the main is not practical.
