Professional Sewer Repair Services in Toronto & GTA

There’s no clean, usable water without a working plumbing system, and it only takes one leak, burst pipe, and virtually any other plumbing emergency for anyone to realize that. Not only are emergency plumbing issues expensive to repair, but these can also cause major inconveniences — and more financial losses — in your daily routine. After all, what are you supposed to do when you can’t shower, cook, or even flush the toilet?

While a leaking faucet or one clogged drain can be easy to fix, some plumbing issues aren’t that simple. Leaks and clogs in the actual sewer line cause much larger problems such as sewage backup and wastewater flooding and even damage to the entire plumbing system. When these happen, you’ll need a professional sewer repair to restore the plumbing system, efficient water supply, and reliable waste disposal.

Trust a Professional

Unlike using a toilet plunger or keeping loose hairs from collecting in the drain, sewage backup and wastewater flooding require the help of a certified plumbing professional. Drain King Plumbers offer sewer line repair and replacement services to restore a plumbing system to optimal function and prevent further damage to the building structure.

Equipped with specialized drain cameras, navigation systems, and plumbing tools, our certified plumbers can perform advanced and reliable sewer repairs to restore optimal water supply and eliminate blockages caused by waste buildup. Enjoy the utmost peace of mind, minimal lifestyle disruptions, and long-term savings compared to DIY solutions that risk further damage.

When to Book a Sewer Repair

Whether it’s a large-scale sewage backup or pesky leaks and clogging that won’t go away, Drain King Plumbers can respond to plumbing emergencies and perform high-quality sewer repairs 24/7. Here are the most obvious signs that you need to call in a repair crew:

Burst, cracked, collapsed, or punctured pipes
Consistent clogs, backups, and slow draining in multiple areas of your home, indicating blockages in the main sewer line rather than just the individual drains
Foul odours throughout the house, which point to sewage backup caused by grease and waste item buildup that can result in wastewater flooding anytime, especially during flood season
Low water pressure caused by clogged or deteriorated pipes as a result of corrosion due to the buildup of chemicals
Leaky or misaligned joints in plumbing fixtures
Tree root intrusion into pipes and the sewer line, which may not be visible right away until a pipe bursts, but can be prevented by regular sewer and plumbing maintenance
Wet or muddy areas on the lawn, indicating excess moisture or leaky pipes or worse, wastewater leaking from the sewer line.
Should a leak occur underground, it is possible that the wastewater leaking from the sewage line could actually fertilize your yard. If you notice an uncharacteristically green patch of grass on your lawn, it could suggest an underground leak. This leak could cause flooding in your house and yard.

Sewer Replacement

Depending on the amount of damage, a sewer repair may not be enough to restore the plumbing system. For ageing systems and fixtures, as well as particularly large backups, a sewer replacement may be more effective at addressing drainage and water supply issues. A sewer inspection using a drain camera can confirm problems in the sewer line and help our plumbers recommend either a repair or a full replacement.

Here are the most common indicators that a full sewer replacement is the better, smarter option for resolving plumbing issues:

Older homes (i.e. over 50 years old) complete with the original plumbing system that has since deteriorated due to waste buildup and clogs
Recurring clogging, draining, leaking, and low water pressure issues
Presence of old, big trees in the yard with roots that are very likely hitting or wrapping around underground pipes.

Trenchless Sewer Repair

No one likes the thought of undergoing a massive sewer repair. Aside from the scheduling hassle and higher cost of emergency repairs, homeowners also run the risk of being left with a lawn in disarray as massive holes or trenches are dug into the ground to install a new sewer line. But that’s quickly changing.

Trenchless sewer repair is the latest plumbing technique for hassle-free line repair or replacement. By using a trenchless pipe, a new sewer line can be installed without the need for excavation.

Instead of digging trenches, two access holes are drilled into either end of the damaged pipe, and a cable with a pipe bursting head is inserted and pulled along the length of the entire length. This fractures the old pipe and allows for a corrosion-resistant sewer line to be pulled into position. Get back to using your home’s plumbing fixtures in no time — without the risk of sewage backup and wastewater flooding.

Don’t wait for sewage backup and wastewater flooding to damage your property. Not sure if your sewer line is up-to-date? Book a sewer inspection and repair or replacement with Drain King Plumbers. Call us today at 833-983-5301 or contact us here when you’re in need.

Sewer Repair: Frequently Asked Questions

Trenchless sewer repair suitability depends on the pipe’s condition, alignment, size, material, and available access. At Drain King Plumbers, we use camera inspections to identify damage and assess suitable options. Relining requires a clear pathway through the existing pipe; significant collapses, displaced joints, or sagging sections may need separate correction first. A liner follows the existing route, so it cannot correct an improper slope. Root growth and deposits also need removal before lining. Where relining is unsuitable, trenchless replacement may still be possible. We explain the recommended approach based on inspection findings, including where excavation may be necessary.

Yes, tree root damage can often be repaired without replacing the entire sewer line, particularly when damage is limited to one area. We use camera inspections to locate root intrusion and assess the surrounding pipe. Root cutting or suitable hydro-jetting can clear the obstruction, but clearing roots alone does not repair cracks or damaged joints. Depending on the findings, sewer repair may involve localized patch relining, lining a longer section, or replacing only the damaged portion. If the pipe has widespread deterioration or collapsed sections, more extensive replacement may be necessary. Our recommendation depends on what the inspection reveals.

Sewer line repair addresses damage, pipe relining repairs a pipe from the inside, and replacement installs new piping in place of the damaged section or line. Sewer repair is the broader term and can include targeted work such as patching a localized defect. Relining uses a resin-based liner inside the existing pipe after inspection and cleaning, leaving the original pipe in place. Replacement may involve excavation or a trenchless method such as pipe bursting. We assess the extent of deterioration and explain which approach suits the condition of your line, rather than assuming every problem requires full replacement.

Plumbers confirm a successful sewer repair by checking the repaired section, drainage performance, and any testing required for the work performed. A follow-up camera inspection can reveal remaining obstructions, visible defects, or problems with a newly installed liner. Flow checks help establish whether wastewater moves through the line, but flowing water alone does not prove that every joint is watertight. Applicable leak testing and municipal inspections provide additional checks. We recommend discussing the verification steps before approving the work, including whether camera footage will be available. Required testing may need to happen before buried pipework is covered, not just after completion.

Yes, Toronto homeowners generally need a plumbing and drain permit for sewer repair involving buried pipe repairs or replacement, with inspections appropriate to the approved work. Confirm the requirements for your specific project with Toronto Building before work begins. The City lists outside sanitary sewer inspections at completion, before backfilling, with the piping ready for testing. Homeowners should also confirm who will obtain the permit, arrange inspections, and ensure the permit is closed. We provide a written estimate for approval, giving you an opportunity to clarify the scope and responsibilities before proceeding. Do not assume trenchless work is automatically exempt.

The average cost to repair a sewer line can range from a few hundred to several thousands! A Drain Specialist would be able to determine the scope of work and costs associated with the repair!

A drain camera inspection by a plumbing professional will determine if your main sewer line is broken.

Repairs to a main sewer line can take anywhere from a day to several days depending on the scope of work.

If your sewer line is broken you will likely experience a sewage backup

Generally, repairing a sewer line will require excavation to access and repair the lines

Love the service. Very quick and clean

These guys were very honorable. I had a main drain back up so I decided to call them to clear the obstruction. They were at my house within 2 hrs and honored the $90 or free special to clear the obstruction with the camera which would be a soft obstruction. Unfortunately the work was more involved and I decided not to continue, but they did come quickly, agreed to the special and left without any pressure tactics.

Drain kings were here in about an hour to check on my clogged kitchen sink. He laid out options from minimal to major and what to expect with each in terms of future maintenance. Prices quoted were reasonable it seemed. Jonathan got the drain working quickly and left me the quotes for more extensive upgrades. No pressure just professional advice. I’m happy to recommend DrainKings based on my experience.

I had an extremely unpleasant experience with Drain King Plumbers three years ago. I recently shared this experience with my boss, who strongly encouraged me to leave a review. Although some time has passed, I believe this experience is worth sharing so other customers can make an informed decision before hiring this company. I initially hired Drain King Plumbers to inspect my kitchen faucet, which was leaking around the base whenever I turned on the water. Upon arriving, the two plumbers examined my sink for approximately 5–10 seconds before immediately declaring that it needed to be replaced. I was presented with two options a very basic, unattractive sink for approximately $300 or a much nicer model for around $1,000. I explained that I was renting the condo and could not authorize such a purchase without my landlord’s approval. Despite repeatedly telling them I was not interested in purchasing a sink, both men remained inside my condo for another 30–40 minutes, persistently pressuring me to buy one. I had already declined multiple times, yet they continued pushing the sale. I am a petite woman alone in my condo with two men who were refusing to take no for an answer, I found the situation uncomfortable and intimidating. They had also performed a separate service cleaning my bathroom drains, which had already been paid for. There was absolutely no legitimate reason for them to continue lingering in my home after I had repeatedly declined their sales pitch. The following day, my landlord came by to inspect the kitchen sink himself. After examining the faucet for approximately 10–15 minutes, he discovered that a component had simply come loose. He tightened it with his bare hands. Three years later and still no leak. The cost $0 dollars. This experience left me seriously questioning both their diagnostic practices and their sales tactics. What I needed was an honest assessment and a simple repair, not an aggressive sales pitch for an unnecessary replacement. My advice to anyone considering this company: get a second opinion before agreeing to any expensive repairs or replacements. I cannot speak to how their employees are compensated, but my experience certainly raised concerns about whether sales were being prioritized over providing honest, competent service.

We had big trouble with the toilet. It was Sunday. I looked up 24 hrs plumbing services. I first contacted Mr. Rooter and was told I could book an appointment for the next day. I then called DrainKing. A professional technician showed up in less than 30 minutes, fixed our issue, recommended things to do to avoid the situation happening again and was very nice helping us.

Mathew Escott

Communication with the office was great, they provided a picture of the tech which was appreciated, and he did a great job laying out all of our repair options and explaining why and how things needed to be done a certain way.

Absolutely horrible. They charged me 1500 to get to rid of my tenants drain flies in the shower. 3 days later they are still there and they aren't even apologising and refuse to give me a refunding. Stay away. Go to a small plumbing company that cares about their service and the people they deal with
