Licensed, Local, and Experienced Plumbers
Despite recent upgrades in many areas, numerous homes across Toronto still rely on outdated clay sewer and underground drain pipes. Vitrified clay pipes, commonly used before the 1980s, are known for their strength and resistance to corrosion. However, they have significant drawbacks due to their weight, requiring installation in short segments with multiple joints. Over time, these joints can weaken, allowing small cracks to form and making it easy for tree roots to infiltrate the pipe, causing blockages or even collapses. Replacing these pipes requires specialized skills, far beyond typical homeowner repair capabilities.
At our plumbing company, we have over two decades of experience in replacing sewer and drain pipes in Toronto and the GTA. Our certified team has replaced thousands of feet of underground piping using both traditional trenching and modern trenchless techniques. While trenching is still commonly used, trenchless sewer replacement is one of the most effective and minimally invasive methods available today.
How Trenchless Sewer Pipe Replacement Works
Trenchless sewer replacement is a powerful, minimally disruptive technique that allows us to replace pipes without extensive digging. Here’s how it works:
1. Access Points: We create two small access points – typically one in the basement and another near the property line outside. The exterior access requires a small 3×3 foot excavation to expose the sewer pipe, typically 8-9 feet below ground.
2. Pipe Bursting: A specialized tool called a “bursting head” (or “torpedo”) is inserted into the old clay pipe. This tool breaks apart the clay pipe, creating a clear path for the new pipe to follow. A new, durable PVC pipe is then fed through the old pipe’s path, extending up to 120 feet if needed.
3. Installation Requirements: For this method to work effectively, the old pipe must have the proper slope without depressions and be straight, with no side branch connections. Our expert plumbers recommend a thorough camera inspection to confirm the trenchless method is suitable for your property.
Trenchless Method vs. Traditional Trenching
Advantages of Trenchless Sewer Replacement
• Minimal Disruption: Traditional trenching can damage landscaping, driveways, flower beds, and more. The trenchless method preserves your outdoor space, requiring only small access points.
• Time and Cost Efficiency: Trenchless pipe replacement is faster, which can reduce labor costs, saving you time and money.
• Enhanced Durability: Unlike pipe liners, which can sometimes shift, the trenchless “pipe burst” technique installs a brand-new pipe with fully glued joints, eliminating gaps that might allow root intrusion.
When Trenching Is Necessary
Trenching remains essential for new residential sewer installations or when working on new construction sites, where existing landscaping isn’t a concern.

Frequently Asked Questions – Trenchless Sewer Pipe Replacement in Toronto
Can a sewer pipe with a negative slope or depression be repaired using trenchless methods?
Trenchless repair methods are not suitable for sewer lines with a negative slope or significant pipe depression. Correcting the slope requires excavation to properly regrade the pipe with new bedding (soil and gravel) so wastewater flows correctly toward the municipal sewer system.
Trenchless techniques are best used when the existing pipe alignment is structurally sound and has a proper slope.
What is the difference between pipe bursting and sewer lining (CIPP)?
There are two primary trenchless sewer replacement methods used in Toronto:
- Pipe Bursting:
This method involves breaking the old pipe while simultaneously pulling in a new pipe. It typically requires two access points (such as the basement and the property line) and may take 1–2 days to complete. - Sewer Lining (CIPP – Cured-In-Place Pipe):
This technique installs a new liner inside the existing pipe without excavation. It usually requires access through a cleanout and can often be completed in one day.
The main difference is that pipe bursting replaces the pipe entirely, while CIPP creates a new pipe within the existing one.
Can I choose the trenchless method for my sewer pipe replacement?
The appropriate trenchless method depends on the condition of your existing sewer line. Some limitations apply:
- Sewer lining (CIPP) cannot be used if the pipe has major offsets, collapses, or severe structural damage.
- Pipe bursting is more suitable when the existing pipe is significantly damaged or misaligned.
A professional sewer camera inspection is the best way to determine the most effective solution. Mister Plumber and Sewer Expert recommends a detailed inspection before proceeding with any trenchless sewer upgrade in Toronto.
What factors affect the cost of trenchless sewer pipe replacement in Toronto?
Several factors influence the cost of sewer repair or replacement, including:
- Depth of the sewer pipe
- Length of the pipe being repaired or replaced
- Pipe diameter and material
- Soil conditions and ground stability
- Accessibility (basement access, cleanouts, or property line access)
- Landscaping, driveways, or structures above the sewer line
Every property is different, so a proper inspection is required to provide an accurate and transparent quote.
What is the best replacement method for old clay sewer pipes in Toronto homes?
Many older homes in Toronto still have original clay sewer pipes. Both trenchless methods are reliable, but the right choice depends on the pipe condition:
- If the pipe has joint separations, cracks, or shifting, pipe bursting is often preferred because it installs a completely new, durable pipe (typically PVC).
- If the pipe is structurally intact with minor deterioration, sewer lining (CIPP) may be a suitable and less invasive option.
