What we run into most

Real-World Plumbing Issues We Repair Fast

We've seen every issue underground plumbing work can uncover. Here are the problems our clients call us about most often.
🚧

Sewer Line Fully Collapsed

A collapsed sewer lateral usually shows up as repeated backups, slow drains throughout the home, or a sinkhole forming in the yard. Trenchless relining is not an option once a pipe has fully caved in. We excavate and replace the damaged section with correctly sized pipe.

🕳️

Sinkhole Forming in the Yard

A sudden depression in the lawn often means a broken pipe below has been washing soil away for months before it became visible. Left alone, the void can spread toward a foundation or driveway. We locate the source, excavate safely, and repair the failed section.

💧

Water Bill Spiked With No Visible Leak

An unexplained jump in water usage often points to a slow leak in an underground service line rather than anything inside the home. These leaks can run for weeks before surface signs appear. We pinpoint the leak location before recommending any digging.

🌧️

Basement Floods Every Heavy Rain

Recurring basement water during storms usually means groundwater has no proper path away from the foundation. A shallow or poorly graded drainage system will not solve it. We excavate a correctly sloped French drain or sump pump pit to redirect water for good.

⚠️

Old Lead Water Service Line

Homes built before mid-century sometimes still have a lead water service line, which is a genuine health concern once corrosion sets in. Replacement requires excavating both the private and sometimes public side of the line. We coordinate the full replacement properly.

🛣️

Driveway Cracking Above a Buried Pipe

Cracking or sinking pavement above a service line often means the pipe below has shifted or is leaking into the base material. Ignoring it lets the damage spread across more of the surface. We excavate the affected section and properly restore the pavement afterward.

🔧

Sump Pump Pit Not Collecting Water

A pit that was dug too shallow or without proper slope will not draw groundwater effectively no matter how strong the pump is. This usually traces back to poor excavation work from a previous installation. We re-excavate the pit to the correct depth and grade.

🌳

Tree Roots Invading a Buried Line

Root intrusion is one of the most common causes of slow drains and recurring clogs in older sewer laterals. Left unaddressed, roots eventually crack the pipe entirely. We assess whether trenchless relining can clear it or whether excavation is required.

Unsure Whether a Repair Needs Full Excavation

Not every underground plumbing problem requires a full dig, but guessing wrong wastes money either way. A camera inspection is the only reliable way to know for certain. We assess the line first and recommend the least disruptive method that will actually solve the problem.

Daniel R.

Handled our sewer lateral replacement perfectly

Our sewer line had fully collapsed and we needed a full open-cut replacement. Core Ontario Plumbing Services walked us through the permit process, kept us updated during the dig, and restored our driveway so well you cannot tell it was ever touched.

Saved our mature trees with trenchless work

We were worried about losing two large trees near our water line, but the crew explained trenchless pipe bursting could work in our case. They pulled it off without disturbing the root systems at all.

Good work, took a bit longer due to rocky soil

The dig took an extra day because of rocky soil conditions the crew found once they started, but they explained why upfront and did not try to rush it. The finished sump pump pit works exactly as expected.

Karen L.

Caught a gas line we did not know was there

The utility locate before digging found an old gas line running closer to our property than we realized. Core Ontario Plumbing Services adjusted the trench path to avoid it completely and still finished on schedule.

Victor M.

French drain finally solved our basement flooding

Every heavy rain used to flood our basement corner. The team excavated a proper French drain around the foundation with real attention to slope, and we have not had a single issue since it was installed.

Priya S.

Honest about excavation versus a quick patch

I called expecting a simple repair, but the technician showed us the camera footage and explained why a full excavation was actually needed. Appreciated the honesty instead of a temporary fix that would have failed again.
