What we run into most

Household Drain Trouble We Resolve

We've seen every mistake a new build's plumbing system can run into. Here are the problems our clients ask us about most often.
🛁

Bathroom Layout Adds Unnecessary Cost

Fixtures scattered far from the mechanical room or from each other require longer pipe runs and more labor than a clustered layout. This drives up the total plumbing budget without adding any real benefit. We review architectural plans early and flag layout changes that reduce cost before framing locks anything in.

Plumbing Rough-In Fails Inspection

A failed rough-in inspection usually traces back to incorrect pipe slope, undersized lines, or a failed pressure test. Correcting it after the fact delays the entire build schedule. We treat inspection as a hard checkpoint and verify every specification before the inspector arrives.

🔥

Gas Appliances Underperforming

Gas lines sized for the first appliance rather than the full planned load cause pressure drops that leave later appliances underperforming. This often isn't discovered until the home is fully equipped and in use. We calculate total gas load across every appliance before running any line.

🚿

Slow Drains Discovered After Move-In

Incorrect vent placement during rough-in can cause slow drains and gurgling fixtures that only become obvious once residents move in. Fixing it after walls are closed means reopening finished surfaces. We confirm vent placement and drain slope during the rough-in inspection stage.

⚠️

Plumbing Conflicts With Other Trades

A plumbing stack or drain line that conflicts with an electrical panel or HVAC duct forces a costly redesign mid-build if nobody catches it early. This kind of conflict is common when trades aren't coordinated. We review the full trade schedule before starting rough-in work.

💧

Choosing Between Tank and Tankless Water Heaters

Homeowners and builders often aren't sure which water heater type fits their household size and hot water demand. Choosing wrong means either inadequate hot water or wasted upfront cost. We walk through the tradeoffs based on the specific home before any equipment is ordered.

🔄

Mid-Project Fixture Changes

A last-minute change to fixture type or location after rough-in is complete usually means reopening a finished wall to relocate plumbing. This is one of the most expensive changes possible in a build. We recommend finalizing fixture selections before rough-in begins whenever possible.

📋

Permit and Inspection Delays

Navigating plumbing-specific permits and inspection scheduling separately from the general building permit can catch builders and owner-builders off guard. Missing this step stalls the entire project. We handle the plumbing permit application and inspection coordination directly.

Uncertainty About New Construction Plumbing Costs

Generic per-square-foot estimates rarely match what a specific floor plan actually requires, leaving builders and homeowners to guess at their real budget. This uncertainty makes planning difficult. We review the actual architectural plans and fixture count before providing a quote.

Testimonials

Hear From Homeowners We've Helped

Builder T.M.

Reliable trade partner across three new builds

We've used Core Ontario Plumbing Services on our last three custom homes. They coordinate directly with our framing schedule and have never been the reason for a delay. Rough-in passes inspection on the first try every time.

Homeowner K.D.

Caught a layout conflict before it became a problem

During our custom build, the plumber flagged that our planned island sink would need a much longer drain run than we realized. We adjusted the kitchen layout slightly and saved real money on the final plumbing bill.

★★★★★ 2025-10-19
General Contractor R.P.

Good work, one inspection delay

The rough-in itself was solid, but we had a minor delay waiting on a re-inspection after a small fitting adjustment. The crew handled the correction fast and it didn't set the overall schedule back much.

★★★★☆ 2025-06-11
Owner-Builder S.A.

Walked me through tank vs tankless clearly

As a first-time owner-builder I had no idea how to choose a water heater. The team explained the tradeoffs based on our household size and we ended up with a tankless system that's worked perfectly.

★★★★★ 2026-01-08
Builder J.C.

Handled gas line sizing correctly from the start

Our home has a furnace, tankless water heater, gas range, and fireplace all on one system. The plumber calculated total load upfront instead of guessing, and every appliance runs at full pressure.

★★★★★ 2025-11-27
Homeowner L.F.

Clear pricing based on our actual plans

They reviewed our full architectural drawings before quoting instead of giving us a generic per-square-foot number. The final invoice matched the original quote almost exactly, which we did not expect.
