Drain Line Repair

When do sewer pipes need replacing or repairing?

When snaking the drain cannot clear the line, the pipes will need to be replaced. In some cases pipes can develop too much buildup and cannot be repaired. Some of the most common issues homeowners face when drains need to be replaced/repaired are caused by roots in the pipes, cast iron corroding, pipes shifting in the ground, and grease built up over years.


What if I have roots in my drains?

The number one cause of sewer back ups in the GTA is when tree roots have penetrated the clay pipes in the ground. Clay pipes are susceptible to being compromised by roots at the joints which were held together by cement years ago. Over time, the cement erodes and breaks away; this is generally where the roots penetrate the pipes.

Once the roots have entered the pipes they will continue to grow. The drain can be snaked to get rid of the roots however if this not dealt with in a timely manner, roots can quickly fill the entire pipe. 


In this instance, the drain can still be snaked but will only make a small sized hole and over time the roots will grow back causing no water to pass through. The best solution is to locate the roots with a drain inspection camera and remove the section of clay pipe where the roots have entered, then replace with PVC pipe.

Grease Buildup

A slow draining kitchen sink can often be caused by grease buildup in the pipe. When fats, oils, and grease are washed down the sink or toilet, they enter the plumbing system and cool, harden and stick to the inside of the drain pipes.


Over time, the grease will build up and can block the entire pipe–both on the homeowners and city property. When grease buildup causes the drain to slow down, the first step is to snake the drain to create a path for the water to escape. If the drain cannot be cleared with the snake, in most instances the pipe will have to be cut out and replaced.

Drain Line Replacement

Clay pipes can crack and/or shift if they aren’t properly supported.


No pipe is safe from possible wear especially if they were not installed correctly or maintained properly. Cast iron pipes can corrode and rust, and any pipe can break due to the pressure from the inside (water) and outside (the ground) the pipe.

What is the sewer line repair procedure?

  • Our team provides you with a work plan once the problem is assessed by our technician with a visual camera inspection.

  • Once the work plan is agreed on, we pass it onto our engineering team. Our engineers will provide the drawing, approve it with the city and obtain the permit for the project.

  • We expose the existing sewer line and replace it with the new one.

  • Once the work is performed, our engineers and the city representative inspect the work.

  • The line is back-filled with gravel and the construction site is cleaned.

  • New concrete is poured and finished with existing floor
