Building without a general contractor?

 

You run the build.We run the plumbing.

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.

  • Not sure when the plumber is needed→A clear schedule of every visit, start to finish
  • Permits and inspections to chase→We file the plumbing permit and book each inspection
  • Separate trades for gas, heat and water→One licensed company for all of it
  • A quote that grows mid-build→A written scope, with changes approved by you first
  • Well and water treatment questions→Water treatment sized to your actual well test

Send us your drawings

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

 

Seven stages.One plumbing contractor.

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.

  • Plan review and written priceWe price the plumbing from your drawings and point out anything that will cost you later, like a fixture with no clear drain path.
  • Underground plumbingDrains and supply lines under the basement slab, before the concrete is poured.Inspected before it is covered
  • Water service and sewer connectionThe connection to municipal water and sewer, or to your well and septic system.Inspected before backfill
  • Rough-inSupply lines, drains and vents run through the framing for every fixture, before insulation and drywall.Inspected before walls are closed
  • Gas pipingGas lines to the furnace or boiler, water heater, range and any other appliances.
  • Mechanical roomWater heater, softener, reverse osmosis, backflow protection, and boiler or radiant floor heating if your home has it.
  • Fixtures, trim and finalToilets, faucets, showers and appliance connections, tested and ready to use.Final inspection

Inspection stages vary by municipality and by job. We confirm what your town requires when we apply for the permit.

Permits and inspections are part of the job

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.

Why builders and homeownerschoose Einwechter

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.

  • Licensed plumbing contractorFully insured before we start: $5 million liability, plus WSIB (workplace insurance), so you’re never on the hook if someone gets hurt. TSSA certified (Ontario’s fuel safety authority) for gas and boiler work.
  • The heat and the water tooBoilers, radiant floor heating, softeners and reverse osmosis are work we do ourselves, so the mechanical room is one company’s responsibility.
  • Changes approved firstIf the plan changes mid-build, you see the price of the change before we do it.

Questions owner-builders ask

New home plumbing FAQ

Can I build a house without a general contractor and still hire you?

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.

When should I call a plumber on a new build?

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.

Who gets the plumbing permit and books the inspections?

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.

What plumbing inspections does a new home need?

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.

How much does the plumbing cost for a new home?

$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.

I am on a well and septic. Can you handle that?

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.

Do you install radiant floor heating and boilers on new homes?

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.

Do I pick my own fixtures?

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.

Why do you recommend the fixtures you supply?

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.
