Plumbing Services in Ottawa

Red Seal plumbers for Ottawa homes and businesses. The big, messy jobs other plumbers send away are our specialty, and we still handle the everyday repairs that keep a house running.

Not every job is a big one. Our plumbers also handle:

  • Frost-free hose bibs and outdoor taps
  • Toilets, faucets, showers and fixture installation
  • Shut-off valve replacement
  • Washer, dishwasher and fridge water line hook-ups
  • Burst and frozen pipe repair

Small jobs are priced the same way as big ones: a flat price, explained before we start. How our pricing works.

“I have called on the Irish Plumber to do several jobs for us--one was a big job of replacing the stack, our old cast iron drain, which took two days, and twice now for small leaks in copper pipes that took about 30 minutes each. They have always been professional, knowledgeable and friendly.”

“We were very pleased with the work that Thomas from The Irish Plumber did at our house. It was a complicated fix to address a leak in a tight spot, and Thomas did a great job. We received a prompt response to our call and pricing was discussed up front - no surprises.”

Questions Ottawa homeowners ask us

Do you only work on older homes?
No. We work on homes of every age across Ottawa. Older homes are where we stand out, because their sewer lines, cast iron and water services need experience to diagnose and fix properly.
How does your pricing work?
We charge a flat price per job, not by the hour, and you approve it in writing before work starts. There's a call-out fee to come out and assess, and we tell you the amount on the phone before booking. How our pricing works.
Will you just sell me the most expensive fix?
No. We show you what we find, often on camera, and give you options from the least invasive up, with what each one fixes and costs. Plenty of our reviews mention that we didn't push extra work.
What happens to my floor, walls or yard?
We protect what we can, open only what we need, and put it back: concrete re-poured, sod and interlock relaid, the site cleaned up. Restoration is on the written quote.
