New Homes, Custom Homes & Owner-Builders
Building with a general contractor or managing the build yourself, a licensed local plumbing contractor takes the whole plumbing scope: underground, rough-in, gas, water treatment and fixtures.

A written number for the plumbing scope before anything is ordered.
We apply for the plumbing permit and book each inspection for our work.
We tell you what has to be ready before each visit, so other trades are not held up.
Plumbing, gas, boiler, radiant floor and water treatment under one roof.
Building without a general contractor?
When you are your own general contractor, every trade asks you the same questions: when can I start, what do you need from me, and who books the inspection. For the plumbing, the answer is us.
Call us before the drawings are final. The underground plumbing goes in before the basement slab is poured, so it is one of the first trades on site and one of the hardest to change later.
We review the plans, flag anything that will cause trouble later, and give you the plumbing price in writing.
How a new home gets plumbed
Here is the order the plumbing usually goes in on a new home, and where the inspections fall. We tell you before each stage what needs to be ready on site.
Inspection stages vary by municipality and by job. We confirm what your town requires when we apply for the permit.
Ontario municipalities require a permit for plumbing work, and an inspector has to see underground work before it is buried. In Kitchener, a permit is needed for any plumbing work on water, sanitary or storm lines, and the inspector must see the work before backfilling. When you hire us, we apply for the plumbing permit, book the inspections for our scope, and meet the inspector on site.

We take the plumbing scope from design to completion, as the subcontractor to a general contractor or working directly for the homeowner. The plumbing gets planned, not fitted in afterwards.
Serving Waterloo Region, Guelph and east to Halton from New Dundee.

They took the time to make sure they understood what we needed on each visit and got the job done. We have been using them for years for a good reason.

Questions owner-builders ask
Yes. We work directly for owner-builders and as a subcontractor to builders. Either way, our scope is the plumbing, gas piping and any heating or water treatment you hire us for, priced in writing.
Before the drawings are final, and well before the basement slab is poured. The underground plumbing goes in first, and moving a drain after the concrete is down is expensive.
We do, for our scope. We apply for the plumbing permit, book each inspection and meet the inspector on site. Each municipality has its own process, and we confirm what yours requires when we apply.
Usually the underground plumbing before it is covered, the water service and sewer before backfill, the rough-in before the walls are closed, and a final. Your municipality sets the exact stages.
$40,000 to $50,000 plus HST is typical for two bathrooms, a kitchen, laundry and a mechanical room with a water heater. City or well water, sewer or septic, water treatment and the fixtures you choose all move the number.
Yes. We connect the house plumbing to your well and septic system and size water treatment to your actual well test, because well water can need iron, sulphur or bacteria treatment as well as softening.
Yes. Radiant in-floor heating and boilers are quoted from the floor area, the floor build-up and the heat load of the house. See boilers and hydronic heating.
Your quote includes a fixture allowance: a budget for good builder-grade fixtures we recommend. Go with our recommendations and the price you see is the price. Want a nicer tap in the kitchen and a basic one in the laundry? Move the budget around. Go over the allowance and you pay the difference; choose something less expensive and the savings come off.
You can also supply your own fixtures. We install them and make sure everything works before we leave, but we can’t warranty equipment we didn’t supply. We guarantee our work for a year when we supply the equipment. We pick brands we trust, and that’s what lets us stand behind them.
Because the best installation can’t overcome bad parts. Lower-cost toilets come loose over time, crack, develop leaks and clog more easily. Lower-cost faucets use cheaper components that loosen, supply hoses that kink, and threads that start leaking at the connections. Even well-known brands make an entry-level line and a commercial-grade line.
We install what we expect to give you a good result for years, and that is what lets us stand behind it when we supply and install it.
