Professional Drain Repair, Replacement and Cleaning
Drain problems can start with a slow drain or unpleasant odour and eventually lead to sewage backups, water damage, or a damaged sewer pipe. Mister Plumber provides professional drain repair, drain cleaning, drain replacement, and sewer line services in Toronto for residential properties.
Our licensed and insured plumbers diagnose the cause of the problem before recommending a repair or replacement. Depending on the condition and location of the drain, the solution may range from clearing a blockage to replacing a damaged section of pipe or upgrading an entire underground sewer line.
Whether you have an emergency drain problem or want to address an aging plumbing system before it fails, we can help.

How Do You Know Your Drain Needs Repair?
Not every slow drain means the pipe itself is damaged. A blockage can often be removed with professional drain cleaning, while recurring problems may indicate a damaged, deteriorated, or improperly installed pipe.
Contact a professional plumber if you notice:
- Slow-draining sinks, showers, bathtubs, or floor drains
- Repeatedly clogged drains
- Water or sewage backing up into your home
- Gurgling sounds from drains or toilets
- Foul or sewer-like odours
- A toilet bubbling when another fixture is used
- Water appearing around exposed drain pipes
- Visible cracks, corrosion, or leaking drain pipes
- Several fixtures draining slowly at the same time
- Drain problems that return shortly after cleaning
When multiple fixtures react to each other’s use, the problem may be farther downstream in the drainage system rather than at an individual fixture.
Emergency and Non-Emergency Drain Services
Some drain problems require immediate attention. A sewage backup, broken drain pipe, or major blockage can cause water damage and create unsanitary conditions if it is not addressed promptly.
Other drain problems are not emergencies but should still be repaired before they become more serious. A slow drain that repeatedly becomes blocked, for example, may indicate a developing problem inside the pipe.
Mister Plumber provides both emergency and scheduled drain services, including drain cleaning, drain repair, drain replacement, and sewer line work.
What Causes Drain Problems?
Drain problems can have many causes. The appropriate repair depends on what is actually happening inside the pipe.
Hair, Soap and Other Bathroom Debris
Hair, skin particles, soap residue, and other debris can accumulate inside bathroom drains. Over time, this buildup can restrict water flow and eventually cause a blockage.
Grease, Fat and Food Waste
Kitchen drains are particularly susceptible to grease, fats, food particles, and other materials that can accumulate on the inside of the pipe. Pouring cooking grease or oil down the drain can contribute to recurring blockages.
Improperly Disposed Items
Wipes, feminine hygiene products, diapers, paper towels, cotton swabs, dental floss, and other non-flushable materials can cause serious blockages. Even products marketed as flushable can contribute to drainage problems.
Tree Roots
Roots can enter underground sewer pipes through small cracks, defective joints, or deteriorated sections of pipe. Root intrusion can restrict flow and may eventually cause a sewer line to collapse.
Corrosion and Deterioration
Older cast iron and metal drain pipes can deteriorate from years of corrosion. As pipe walls become thinner, leaks, cracks, and other failures can develop.
Pipe Movement or Damaged Joints
Older underground pipes can shift as the ground settles or moves. Disconnected or offset joints can restrict drainage and allow soil, roots, or groundwater to enter the pipe.
Mineral and Scale Buildup
Mineral deposits and internal buildup can reduce the effective diameter of a drain pipe, restricting water flow and contributing to recurring blockages.
Drain Camera Inspection
See What Is Actually Happening Inside the Pipe
A drain camera inspection can provide valuable information when a blockage keeps returning or a damaged underground pipe is suspected.
Our plumbers can use a high-resolution sewer camera to inspect the inside of accessible drain and sewer pipes. Depending on the situation, we can identify problems such as:
- – Blockages
- – Tree-root intrusion
- – Cracked or broken pipes
- – Offset or separated joints
- – Corrosion
- – Heavy buildup
- – Collapsed sections
- – Other abnormalities inside the pipe
For underground sewer problems, a camera equipped with an electronic locator can also help identify the approximate location and depth of a defect. This can be especially useful when determining where excavation or another repair method may be required.
A camera inspection helps us choose the appropriate solution rather than automatically recommending pipe replacement.
Drain Cleaning and Drain Repair Are Not the Same
A clogged drain does not necessarily need to be repaired or replaced.
If the pipe is structurally sound, professional drain cleaning may restore normal flow. Depending on the blockage, our plumbers may use mechanical drain snakes or high-pressure water jetting.
If the pipe itself is cracked, collapsed, badly corroded, separated, or otherwise structurally damaged, cleaning alone will not solve the underlying problem. In these situations, the damaged section may need to be repaired or the pipe replaced.
Professional Drain Cleaning
Drain Snaking
Mechanical drain cleaning equipment can be used to break through and remove many types of blockages. The appropriate cable and cutting head depend on the size and condition of the drain.
Hydro Jetting
High-pressure water jetting can be used for certain stubborn blockages and heavy internal buildup. It can help clean the interior of suitable drain and sewer pipes by using pressurized water to remove accumulated debris.
Hydro jetting is not appropriate for every damaged or deteriorated pipe. The condition of the pipe should be considered before high-pressure cleaning is performed.
Drain Pipe Repair
Not every damaged drain requires complete replacement. When the damage is limited to a specific section and the surrounding pipe is in suitable condition, repairing the affected section may be possible.
Common residential drain repairs include:
- – Cracked ABS pipe replacement
- – Damaged fittings and elbows
- – Leaking connections
- – Corroded metal drain pipes
- – Broken basement drain pipes
- – Localized drain pipe replacement
- – Repairs to exposed above-ground drainage
- – Repairs to accessible underground drainage
The repair method depends on the pipe material, location, accessibility, and extent of the damage.
Above-Ground Drain Repair and Replacement
Drain pipes inside walls, ceilings, basements, kitchens, bathrooms, and other areas can deteriorate or become damaged.
Common examples include leaking cast iron stacks, cracked ABS fittings, and corroded metal drain piping.
When the damaged pipe is accessible, we can remove the failed section and install new compatible piping and fittings. If a pipe is located behind drywall or a finished ceiling, some access opening may be necessary.
Unlike underground trenchless sewer replacement, interior drain pipe repairs generally require physical access to the damaged section.
Cast Iron Drain Stack Replacement
Older Toronto homes may have cast iron drain stacks that have deteriorated after decades of service.
Cast iron can develop internal corrosion, thinning walls, cracks, and leaks. When deterioration is extensive, replacing the affected section or the entire stack may provide a more reliable long-term solution than attempting repeated temporary repairs.
Our plumbers can assess the condition of the stack and determine whether localized repair or replacement is appropriate.
Underground Drain and Sewer Line Replacement
A damaged underground drain or sewer line may require replacement when it is severely cracked, collapsed, repeatedly obstructed by roots, or otherwise beyond practical repair.
Depending on the location and condition of the pipe, replacement may involve excavation or a trenchless method.
Trenchless Pipe Bursting
For certain underground sewer replacement projects, pipe bursting can reduce the amount of excavation required.
With this method, specialized equipment pulls a bursting head through the existing pipe. The old pipe is fractured or displaced while a new pipe is installed along the same general pathway.
Pipe bursting can be particularly useful for certain aging clay sewer pipes. However, it is not suitable for every property or every pipe configuration. The existing sewer, access points, alignment, surrounding utilities, and other site conditions must be evaluated first.
When trenchless replacement is appropriate, it can reduce surface disruption compared with conventional excavation.
Repairing a Broken Basement Drain
A broken basement drain can cause water leakage, drainage problems, unpleasant odours, or sewage backup.
The repair depends on where the damaged pipe is located and whether the surrounding piping is still structurally sound. An accessible section may be repaired by removing the damaged portion and installing new pipe and fittings.
If the problem extends into an underground section beneath the basement floor, additional investigation may be required before determining whether localized repair, excavation, or another replacement method is appropriate.
How We Diagnose a Drain Problem
A professional drain repair starts with identifying the actual cause of the problem.
Depending on the symptoms, our plumbers may:
- Inspect the affected fixtures and drainage system.
- Determine whether the problem is a localized blockage or a larger drainage issue.
- Use mechanical drain cleaning equipment when appropriate.
- Perform a camera inspection when a damaged or underground pipe is suspected.
- Locate an underground defect when necessary.
- Explain the available repair or replacement options.
- Provide a clear estimate before proceeding with the recommended work.
The goal is to address the underlying problem rather than repeatedly treating the same symptoms.

Frequently Asked Questions About Drain Repairs in Toronto
Who is responsible for a collapsed underground drain pipe in Toronto?
Responsibility depends on the location of the damaged pipe and whether it is part of the private plumbing system or the City-owned sewer infrastructure.
Generally, the homeowner is responsible for private drainage and sewer piping located on their property up to the applicable connection point. The City of Toronto may be responsible for portions of the municipal sewer system.
A sewer camera inspection with an electronic locator can help determine where a problem is located. Property-specific responsibility should be confirmed with the City or the appropriate authority when necessary.
Does a slow drain always mean the drain pipe is damaged?
No. A slow drain can be caused by a simple blockage, buildup, or other obstruction. However, recurring blockages can sometimes indicate a damaged, improperly sloped, root-affected, or deteriorated pipe.
If the problem keeps returning after cleaning, further inspection may be appropriate.
Can a cracked ABS drain pipe be repaired?
Yes. A localized crack or damaged ABS fitting can often be repaired by removing the damaged section and installing new ABS pipe and fittings using the appropriate solvent-welding method.
The condition and accessibility of the surrounding piping should be evaluated before deciding on the repair.
My old cast iron drain stack is leaking. Does it need to be replaced?
Not necessarily in every case. The appropriate solution depends on the location and extent of corrosion or damage.
Minor localized damage may sometimes be addressed with a localized repair, while severely corroded or deteriorated cast iron may be better replaced. An inspection can help determine the most appropriate option.
Can a corroded brass drain pipe under my kitchen sink be repaired?
In many cases, replacement is the better solution when a brass drain pipe or fitting has significant corrosion.
Depending on the location and building requirements, replacement materials may include new brass or approved plastic drainage materials. Condominiums and other buildings may have specific requirements regarding which materials can be used.
Can you repair a drain pipe behind drywall without opening the wall?
Generally, physical access is required to properly remove and replace a damaged section of interior drain pipe.
A plumber can often minimize the size of the access opening, but attempting to repair a concealed damaged pipe without reaching it is usually not practical.
Should I repair or replace my underground sewer line?
It depends on the condition of the pipe.
A localized defect may be repairable, while extensive cracking, collapse, severe root intrusion, repeated failures, or widespread deterioration may justify replacement. A camera inspection can provide important information before deciding between repair and replacement.
Can trenchless pipe bursting be used for every sewer replacement?
No. Pipe bursting is suitable for many applications but not all.
The existing pipe’s material, size, alignment, condition, depth, access points, surrounding utilities, and site conditions must be considered. A professional assessment is required to determine whether trenchless replacement is appropriate.
How can I prevent drain problems?
You can reduce the risk of blockages by keeping grease, cooking oils, wipes, feminine hygiene products, paper towels, dental floss, and other inappropriate materials out of your drains.
Using drain strainers in sinks and showers can also help prevent hair and debris from entering the drainage system.
For recurring drainage problems, professional inspection is recommended rather than repeatedly relying on chemical drain cleaners.
