What we run into most

Frequent Drain Trouble We Repair Fast

We've seen every issue a home plumbing system can develop. Here are the problems our clients call us about most often.
🚽

Toilet Keeps Running After Flush

A worn flapper valve or a fill valve that no longer seats correctly is almost always the cause of a toilet that keeps running. Left unaddressed, this can waste hundreds of gallons of water and drive up the monthly bill. We replace the faulty part and confirm the tank seals properly.

🚿

Low Water Pressure Throughout the House

Mineral buildup inside older pipes or a partially closed shutoff valve usually causes pressure drops across multiple fixtures at once. This often gets mistaken for a municipal supply issue when the real cause is inside the home. We inspect the system and correct the actual source.

🔧

Drain Keeps Clogging in the Same Spot

A recurring clog in the same drain usually means a partial blockage or a structural issue further down the line rather than a simple surface clog. Repeated snaking without addressing the root cause wastes time and money. We run a camera inspection to find and fix the real problem.

🔥

Water Heater Not Producing Enough Hot Water

Sediment buildup at the bottom of the tank insulates the heating element and forces the unit to work harder than it should. Left ignored, this shortens the water heater's usable life significantly. We flush the tank and test the pressure relief valve to restore proper heating.

💧

Sudden Spike in the Water Bill

An unexplained jump in water usage usually points to a hidden leak somewhere in the supply line or behind a wall. Left unresolved, a hidden leak can cause serious structural damage before it becomes visible. We locate the source and repair it before it spreads further.

🔊

Gurgling Sounds Coming From Drains

Gurgling after using a sink or toilet usually signals a venting issue or a partial blockage further down the drain line. Left unaddressed, this can lead to slow drains throughout the home and eventually a full backup. We diagnose the vent and drain system together to resolve it.

🚰

Burst Pipe Causing Active Water Damage

Freeze and thaw cycles or age-related corrosion are the most common causes of a pipe bursting suddenly. Every additional hour of standing water increases the risk of structural and mold damage. We respond quickly to shut off the source and repair the affected section.

👃

Sewage Smell Near a Floor Drain

A persistent sewage odor usually means a dried-out trap or a venting problem allowing sewer gas to escape into the home. Left unresolved, this is both a comfort issue and a potential health concern. We inspect the trap and venting system to identify the exact cause.

🛠️

Fixture Leaking Behind the Wall

A mismatched supply line connection or an improperly sealed joint from a previous installation often leaks slowly for weeks before becoming visible. By the time it's noticed, real damage has usually already occurred to the surrounding wall or cabinet. We locate and correctly reseal the connection.

Karen S.

Found the real cause of our low pressure

We had low water pressure for months and assumed it was our old pipes needing full replacement. The technician found a partially closed shutoff valve instead and fixed it in twenty minutes. Saved us a huge unnecessary expense.

Camera inspection caught root intrusion early

Our drain kept backing up and Core Ontario Plumbing Services ran a camera down the line right away. They found roots growing into an older section of pipe before it collapsed completely. Glad we called when we did.

Great work, part took a couple extra days

Our water heater needed a specific anode rod that wasn't on the truck, so we waited a couple extra days for it to arrive. The technician kept us updated the whole time and the final repair has been solid since.

Honest about a smaller fix being enough

I called expecting to need a full toilet replacement but the technician explained it was just a worn flapper valve. Cost a fraction of what I braced for and it has worked perfectly since. Appreciated the honesty.

Quick response for a burst pipe

We had a pipe burst on a Saturday morning and the team from Core Ontario Plumbing Services got someone out within a couple hours. They explained everything before starting and the repair held up perfectly through a cold winter.

Fixture installation done right the first time

Had a new kitchen faucet installed and the technician caught that our old supply line wouldn't match the new connection before it became a problem. Core Ontario Plumbing Services handled the adapter as part of the quote with no surprise charges.
