What we run into most

Household Plumbing Issues We Resolve

We've handled the plumbing side of every type of basement renovation. Here are the problems homeowners run into most often.
🚰

Not Sure If the Basement Can Drain by Gravity

Whether new fixtures can drain by gravity or need an ejector pump depends on the basement floor's elevation relative to the main sewer connection. Guessing wrong here derails the entire layout. We confirm this early, before any framing decisions are made.

📐

Plumbing Plan Not Finalized Before Framing Started

Fitting plumbing around an already-framed layout compromises drain slope and pipe sizing, and correcting it later means tearing out finished walls. This is one of the most expensive renovation mistakes. We finalize the plumbing plan before any framing begins.

🔧

Existing Plumbing Rough-In Not Working

A capped drain stub or supply shutoff left unused for years can develop a dried-out trap seal or seize up entirely. Assuming it works without testing risks a mid-project surprise. We test every existing plumbing element during the initial assessment.

Unsure Whether the Basement Needs an Ejector Pump

Fixtures below the home's main sewer connection elevation cannot drain by gravity and need a sewage ejector pump system. Not planning for this upfront affects both budget and electrical requirements. We confirm the need during the planning phase, not partway through construction.

💧

Waterproofing Not Addressed Before Finishing

Installing drywall and flooring over a foundation with an existing leak means the work will eventually need to come back out. This mistake is expensive to correct after the fact. We recommend a waterproofing assessment as an early renovation step.

🛠️

Renovation Sequencing Causing Trade Conflicts

Framing built before drain lines are set, or electrical outlets placed without accounting for wet areas, both create costly rework. These conflicts are common without upfront coordination. We plan plumbing sequencing directly with framing and electrical trades.

🚿

Choosing the Wrong Fixtures for the Drainage System

A basement using an ejector pump performs better with lower-flow fixtures, since every gallon has to be mechanically pumped rather than flowing by gravity. Choosing fixtures without this in mind adds wear on the pump. We match fixture choice to the actual drainage system.

📋

Permits Skipped on Renovation Plumbing Work

Basement renovations involving new plumbing or electrical work require permits and inspections in nearly every municipality. Skipping them can surface during a home sale or complicate an insurance claim later. We pull the necessary permits and schedule all required inspections.

🏠

Basement Renovation Feels Rushed and Poorly Planned

A renovation with plumbing issues showing up soon after completion usually means the initial planning skipped important steps. This shortens the useful life of an otherwise expensive project significantly. We take the time upfront so the finished space performs well for decades.

Owen R.

Plumbing planned perfectly around our layout

Our contractor recommended Core Ontario Plumbing Services to finalize the plumbing plan before framing started, and it made the whole renovation smoother. No conflicts with the electrical or framing crews at any point in the project.

Camille D.

Caught a seized shutoff before it became a problem

During the initial assessment, the technician tested every existing plumbing element in our unfinished basement and found a shutoff valve that had completely seized. Glad they caught it before we were mid-renovation and stuck.

Trevor L.

Great plumbing work, project ran a bit long overall

The plumbing rough-in itself was done efficiently and passed inspection on the first try, but our overall renovation took closer to nine weeks because of scheduling delays with other trades. Not the plumber's fault at all.

★★★★☆ 2025-05-19
Marisol A.

Recommended waterproofing before we even asked

We were focused entirely on the bathroom layout, but the team flagged a minor foundation crack during their assessment and suggested addressing it before finishing the walls. Core Ontario Plumbing Services clearly thinks ahead instead of just doing what's asked.

Dominic F.

Explained the ejector pump situation clearly

We had no idea our basement sat below the sewer line until this project started. The plumber explained exactly why we needed an ejector pump and what it would mean for our layout and budget going forward.

Bianca S.

Finished basement finally feels like real living space

We put off finishing our basement for years because it always felt like too big a project. Core Ontario Plumbing Services handled the plumbing side smoothly and the whole space genuinely feels like an extension of our home now.
