Drain Pipe Repair and Replacement by Licensed Plumbers

A home’s drain system is similar to a tree, with the main sewer pipe acting as the trunk and smaller drain lines branching out from it. These pipes work together to transport wastewater from your plumbing fixtures to the municipal sewer system beneath the road. Depending on the age and type of pipe, materials vary—older underground sewer lines may be made of clay, while newer lines use PVC or ABS. Vertical drain stacks and branches could consist of cast iron, lead, or copper, whereas modern pipes are primarily ABS or PVC.

Unfortunately, pipes—whether old or new—can break down over time due to various factors. In Toronto and the GTA, our licensed plumbers specialize in repairing and replacing both underground and above-ground pipes. Each type of breakdown requires unique tools, fittings, and repair methods, and with over 20 years of experience, our team is a trusted choice for reliable drain and sewer services.

Before the 1950s, vitrified clay pipes (typically 4-inch in diameter) were the standard for residential sewer lines. While strong, these pipes are prone to cracks over time due to soil settling and aging, particularly at the joints. Tree roots can penetrate these cracks, seeking water and nutrients, eventually causing the pipe to collapse.

Our repair process for clay pipes begins with a video camera inspection to locate the problem area. Once identified, our plumbers know exactly where to dig and how deep, minimizing disruption. PVC is now the preferred material for spot repairs, using rubber couplings to create watertight connections between the old clay pipe and new sections.

Repairs can be more challenging when pipes are located deep underground, requiring excavation. Inside the basement, clay pipes are typically no deeper than 3 feet, but outside, they can range from 8 to 10 feet below the surface. Our skilled plumbers handle clay pipe repairs quickly and efficiently. For larger issues, we offer trenchless replacement options, which save time, money, and protect your landscaping.

ABS is a durable, widely-used material for modern drain systems in single-family homes. However, cracks can still occur, often due to improper installation or tension in the pipes. Hot water, especially from kitchen sinks, can degrade the material’s elasticity over time, leading to leaks.

The good news is that ABS pipes are affordable and relatively easy to repair. Our licensed plumbers can cut and replace damaged sections using proper glue and couplings, often completing repairs the same day. Since ABS pipes are typically located above ground, repairs are straightforward, and our team carries all the necessary parts and fittings for efficient service.

Older homes often have cast iron drain stacks, which, over time, can corrode and develop hairline cracks. These cracks may not be immediately visible, but leaks can occur and travel along the pipe, often showing up in lower floors or the basement. The bottom section of the stack, particularly the 90-degree elbow, is where corrosion tends to accumulate, eventually causing blockages.

In such cases, the cast iron stack often needs to be replaced. Our plumbers use snap cutters and diamond saws to safely remove old cast iron sections and install new ABS pipes. We carefully cut into walls where needed, and handle the disposal of all removed materials, ensuring a clean and thorough job.

Copper drain pipes can develop pinhole leaks due to oxidation and the chemicals found in household cleaners like dishwashing liquids, grease removers, and detergents. Wastewater and sludge sitting in the bottom of the pipe can also accelerate the process. In some cases, leaks appear after using a drain snake to clear blockages, as the tool can weaken already compromised areas.

While temporary fixes, such as wrapping the pipe with rubber, are possible, the best long-term solution is to replace the copper pipe with modern plastic materials. This also presents an opportunity to improve the slope of the pipe for better drainage. Our experienced plumbers carry specialized rubber couplings in various sizes, allowing us to perform same-day repairs or replacements as needed.
