Integrity
Plain talk, honest quotes, and no hidden fees — ever. We spell out exactly what needs doing and why.
For over 75 years, Ontario homeowners and businesses have turned to Delta Plumbers first. Born in Niagara, fully licensed, and grounded in honest work and fair pricing, we look after every home as if it were our own.

Over seventy-five years of honest work, fair pricing, and being there when it matters most.
Douglas Parker launched Delta Plumbers with a single van, one toolkit, and a simple pledge — to treat every customer like a neighbour. The very first call? A dripping faucet right here in Niagara.
Word of our dependability earned us our first commercial contract, looking after a cluster of downtown condos. The fleet expanded to four trucks.
By 1976 we'd reached our first ten communities across the region — from Niagara all the way to the edge of the GTA. Ten pins on the map, every one a neighbourhood that put its trust in us.
With ten licensed plumbers on the roster, Delta branched into complete bathroom renovations and new-build construction across Ontario.
We doubled our footprint — ten more communities came on board, bringing us to twenty locations across southern Ontario.
Douglas's son John Parker stepped up to lead the family business, with his brother Murray Parker right beside him — upholding the same hands-on standards their father founded Delta on.
Voted Ontario's Best Plumber by HomeStars for the first time — an honour we've gone on to earn every year since.
We rolled out our round-the-clock emergency line. No more waiting till morning for a burst pipe — we're on call whenever you need us.
In a tough year for everyone, we still reached 8,000 happy customers across Ontario — and handed our milestone customer their entire job on the house.
Twenty-one licensed technicians now serve communities right across Ontario — carrying the very same values Douglas brought to that first job in Niagara.
These aren't slogans stuck on a wall. They're the principles every Delta plumber puts into practice on every job — from the first phone call to the final walkthrough.
Plain talk, honest quotes, and no hidden fees — ever. We spell out exactly what needs doing and why.
Top-grade parts, master-level workmanship, and full code compliance on every job. Cutting corners isn't in our vocabulary.
Fully licensed, insured, and bonded — we safeguard your home, your family, and our crew on every call.
Niagara-born and Ontario-grown. We give back to the communities that helped build us.
Plumbing emergencies don't wait around. Same-day bookings and a genuine 24/7 emergency line, because your time matters.
Every job comes with our satisfaction guarantee. If something's not right, we'll put it right.

Very happy with my tankless water heater installation. Quick and hassle-free process — would recommend.
Money was tight and Peter gave me a few budget alternatives. He saved the day — would recommend to anyone.
