Every one of these came from a household within a short drive of your door.
“Bungalow built in the fifties, tank in a cellar with a four-foot ceiling. They got it in and out through the Bilco door like it was routine. It is, for them.”
H

FAQs
Before You Call, Check Here
Answers to the questions Oshawa homeowners ask us most.
Are you licensed to do plumbing in Oshawa?
Licensed and insured, with permits taken out through the Durham area authority for every job that requires one, so century-home repipes and suite rough-ins alike carry real paperwork.
Can you come out tonight for a flooding basement?
Emergency dispatch runs around the clock across Oshawa for active leaks, sewer backups, and no-water calls, with local crews that know the low streets by name.
The tank just started weeping. Today?
Most Oshawa replacements happen same-day, since the common configurations ride on the trucks and the permit filing is part of the visit, not a follow-up chore.
Galvanized to the attic. Do we have to gut the house?
No. Repiping works through strategic openings planned room by room, and occupied Oshawa homes, tenants included, keep water every evening of the job.
We are legalizing a basement apartment. Do you handle that plumbing?
Yes, from the suite's own hot water source to the full bathroom rough-in, done to satisfy Oshawa's registration inspection and the Ontario Building Code behind it.
Is Durham tap water hard?
Hard enough that kettles, dishwashers, and shower glass show it within months. A metered softener sized to your household solves it measurably.
How do we know the price before you start?
Written quotes come first, free, with scope and total. Oshawa landlords and homeowners approve the number before tools come out, and the invoice honours it.
Where do your Oshawa crews also work?
Whitby, Courtice, Brooklin, Bowmanville, and Newcastle, alongside Oshawa itself, with the same standards across all of it.
Do you serve areas outside of Oshawa, Ontario?
Yes. We serve Oshawa and nearby communities including Whitby, Courtice, Brooklin, Bowmanville, and the surrounding area.
