What we run into most

Frequent Drain Trouble We Resolve

We've seen every type of leak a home's plumbing can develop. Here are the problems our clients call us about most often.
💰

Water Bill Suddenly Went Up

An unexplained spike in the water bill without any change in household usage almost always points to a hidden leak somewhere in the system. Left unchecked, the wasted water keeps adding cost every month while the underlying pipe continues to fail. We pressure test the lines and pinpoint the exact source before recommending a repair.

🔊

Dripping Sound Inside a Wall

A hissing or dripping sound coming from inside a wall usually means a supply line is leaking under pressure even when no fixture is running. Ignoring it lets moisture spread into insulation and framing where mold can take hold within days. We use listening equipment to trace the sound to its exact origin before opening the wall.

💧

Wet or Discolored Ceiling Spot

A damp patch or stain on a ceiling below a bathroom or kitchen typically means water has been seeping from a pipe or fixture above for some time already. The stain usually appears well after the leak has started, meaning real damage may already be underneath the surface. We trace the leak to its source and repair the actual cause, not just the visible stain.

🌫️

Musty Smell With No Visible Source

A persistent musty odor in a room often signals hidden moisture from a slow leak that hasn't yet produced a visible stain or puddle. The smell is frequently the first sign homeowners notice, arriving before any obvious water damage appears. We inspect the surrounding pipes and walls to locate and fix the source.

🚨

Pipe Burst or Cracked Suddenly

A sudden burst or crack, often from frozen pipes or a pressure surge, can release a large volume of water fast and cause serious damage within minutes. Every minute the water runs adds to the cleanup and repair cost. We prioritize active leak calls and can typically stop water loss the same day.

🚿

Leak Under the Kitchen or Bathroom Sink

A leak under a sink is one of the most common calls we get, usually from a loosened supply line connection or a worn seal at the drain. Left alone, the moisture warps cabinet flooring and can spread to the subfloor beneath it. We repair or replace the affected section, which is typically finished within a single visit.

🏗️

Suspected Leak Under a Concrete Slab

Warm spots on the floor or a persistently damp patch on a slab foundation often point to a leaking hot water line running beneath the concrete. This type of leak is easy to underestimate since the damage is largely hidden from view. We locate the leak with acoustic equipment and recommend the least invasive repair option, including rerouting where it makes sense.

⚠️

Old Galvanized Pipes Keep Leaking

Galvanized steel pipes corrode from the inside, and once one section starts leaking, nearby sections are often not far behind. Repeated leaks in the same general area of a home usually mean the pipe material itself is reaching the end of its service life. We assess the full run and give an honest recommendation on repair versus replacement.

🌧️

Outdoor Hose Bib or Spigot Leaking

An outdoor hose bib that drips or leaks at the connection point is often caused by a worn washer or a line that froze and cracked during winter. Left unaddressed, the leak can work its way back into the wall where the bib connects to the home's plumbing. We repair or replace the fixture and check the connecting line for related damage.

Melissa R.

Found the source in twenty minutes

We had a mystery damp patch on the ceiling below our bathroom and no idea where it was coming from. The technician from Core Ontario Plumbing Services traced it to a hairline crack in a supply line behind the wall using a moisture meter. Fixed the same visit and explained exactly what he found.

Caught a second weak spot before it failed

Core Ontario Plumbing Services came out for a leak under our kitchen sink and the plumber noticed the pipe nearby was also starting to corrode. He replaced both sections while he was there instead of letting us call back in a few months. Really appreciated the extra attention.

Great fix, slab access took longer than quoted

Our leak turned out to be under the concrete slab, which meant a longer job than the original estimate suggested. The team was upfront about the added time once they saw the scope and the repair itself has held up perfectly since.

Stopped an active leak within the hour

Water was actively dripping from our ceiling when I called and someone was at the house within the hour. They shut off the source immediately, then came back the next day to complete the actual repair once the area had dried out. Huge relief.

Sandra K.

Honest about our old galvanized pipes

The technician explained that our galvanized pipes were near the end of their life and this leak likely wouldn't be the last one. No pressure to replace everything on the spot, just clear information so we could plan for it. The repair itself was quick and clean.

Derek W.

Explained the water bill mystery

Our water bill had been climbing for months with no obvious reason. The Core Ontario Plumbing Services technician pressure tested our lines and found a small leak in the crawl space we never would have noticed. Fixed it that same day and our next bill was back to normal.
