Main Drains Repair

The One Pipe Everything Depends On

Your main drain is the single line carrying waste from the whole house out to the city sewer. Branch lines serve one fixture. The main serves all of them, which is why a main drain fault shows up as several drains slowing or backing up at once.

Toronto has a lot of older housing stock on clay and cast iron main drains, and mature trees whose roots find every joint. Root intrusion, collapsed sections, bellied pipe and scale build-up are what we see most.

We diagnose with CCTV first, then repair with the least invasive method the pipe will allow, which is usually trenchless relining rather than excavation.

How We Handle Main Drain Work

CCTV Diagnosis First

Expert Professionals — Flood Guard Toronto

We never quote a main drain repair blind. The camera goes in before the price comes out.

Root Removal

Cutting Edge Technology — Flood Guard Toronto

Mechanical cutting and hydro jetting to clear root mass back to the pipe wall.

Trenchless Relining

Fair Pricing — Flood Guard Toronto

A new liner cured inside the old pipe, so the lawn and driveway stay where they are.

Pipe Bursting

Round the Clock Availability — Flood Guard Toronto

Where relining will not do, we pull a new pipe through while fragmenting the old one.

Open Cut When Needed

Customer Satisfaction — Flood Guard Toronto

Some failures need excavation. We keep the dig small and restore the site properly.

Warranted Work

All Inclusive Services — Flood Guard Toronto

Relining is warranted 15 to 25 years, excavation repairs 10 years, in writing.

Signs of a Main Drain Fault

The tell-tale sign is more than one fixture misbehaving at the same time: the toilet gurgles when the washing machine drains, the basement floor drain backs up when you run a bath, or several drains slow together. A single slow sink is a branch line problem. Several at once is the main. Add a sewage smell in the basement or a soggy patch in the yard and it is time for a camera, not a plunger.

Root Intrusion

Roots do not attack a sound pipe. They find an existing crack or a loose joint, then thrive on what is inside. Cutting them out restores flow but does nothing about the opening that let them in, which is why a rooted line that is only ever snaked comes back every year. The lasting fix is to clear the roots, then reline the section so there is no longer a joint for them to find.

Trenchless Relining Explained

A resin-saturated liner is drawn into the existing pipe and cured in place, forming a new jointless pipe inside the old one. It needs only a small access point, it is finished in a day for most residential runs, and it leaves the driveway, walkway and landscaping untouched. It is not suitable for every pipe: a fully collapsed or badly bellied line needs replacement. The CCTV survey tells us which situation you are in before you commit to anything.

What Our Customers Say About Us

Real reviews from real customers across the Greater Toronto Area.

Called Flood Guard at 10pm on a Saturday when our basement drain backed up. They had a technician at our door within 45 minutes. Very professional, and the price was exactly what they quoted.

Scarborough Mark Thompson

We had a recurring clog that two other plumbers could not fix. Flood Guard did a camera inspection, found the root cause, and repaired it permanently. Honest company.

Mississauga Priya Sharma

Flood Guard installed a backwater valve after our basement flooded. The crew was punctual, explained everything clearly, and finished in one day. Highly recommend.

FAQ

How do I know if it is the main drain and not one fixture?

If more than one fixture is affected at the same time, or the basement floor drain backs up when you use an upstairs one, it is the main line.

Will you have to dig up my yard?

Usually not. Trenchless relining handles most cases with a single small access point. We only excavate when the pipe is collapsed or badly bellied.

How long does relining take?

Most residential main drain relining is completed in a single day, including the camera survey before and after.

Why do the roots keep coming back?

Because snaking clears the roots but leaves the crack or open joint that let them in. Relining removes the entry point.

Is the work warranted?

Yes. Relining carries a 15 to 25 year warranty, traditional excavation repairs 10 years on materials and workmanship, all in writing.
