Sewer and Drain Line Services

Customer satisfaction is our number one priority. We make sure that all our sewer pipe replacement services are done right the first time. Before we begin work we do a complete evaluation of your drain system using the latest camera inspection technology. This allows us to get a detailed picture of what is causing your pipe issues so we can do the right sewer line repair. Once we know what the cause of the problem is, we can begin work. In most cases, sewer repairs require excavating the area around the lines. Once we have gained access, the sewer pipe repair can begin.

The sewer replacement is coordinated by experienced project managers who understand the importance of protecting your property’s landscaping. This may include doing trenchless sewage pipe repair which has minimal impact on your greenspace.

Causes of Sewer Line Problems

Sewer replacement is usually an unplanned event. Clogs and damage can form underground, causing a sudden break or crack in the sewer line. The most common reasons for sewer replacement are:

  • Drain age and usage over time can cause pipes to wear and crack over time. If you live in a home that is more than 50 years old, it may be time for a pipe inspection to prevent costly damage to your home.
  • Grease, food, and other debris can cause sewer pipes to clog and back up into your home. Always make sure to never pour anything down a drain other than water.
  • As trees grow and mature, their root systems can clog and crack sewer drains.
  • As temperatures fluctuate, sewer pipes expand and contract which can lead to burst pipes.

Our professional plumbers can pinpoint any risk factors that could lead to pipe damage so you can prevent possible clogs and leaks in the future.

What are the signs of a broken sewer pipe?

If you notice these signs in your home, you could have a broken sewer pipe. Before there are any further damages to your home, give us a call. We’re here to help.

Flooded or smelly yard

If your yard becomes flooded, that could mean you have a broken sewer pipe. A burst pipe can create a pool of water on your lawn and may even smell like sewage.

Difficult drainage

If several draining areas of the home have problems, there could be a clog in your main sewer line. One key red flag to watch out for is a toilet that makes gurgling noises when flushed.

Water damage in the house

The spread of mould on the floors or walls or your basement could initiate a drain leak or break in your home.

Sewer Line Repair and Sewer Line Replacement Options

When you have a broken sewer pipe in need of repair there are two main options plumbers may use to carry out the fix. After a camera inspection and consulting the homeowner, we will typically recommend either of the following:

Pipe lining

For pipes that are minimally damaged, we can insert an epoxy-covered inflatable tube into your line, known as pipe lining. Once inserted, the epoxy hardens and covers up the leak.

Pipe bursting

If the sewer line is too damaged for pipe lining, we may suggest trenchless repair which is when we insert a special drill bit through the old line. The bit destroys the old line and instantly replaces it with a new line as it works through your system. This costs more money and takes more time, but doesn’t require excavation.

Note that if there is too much damage to the sewer system, digging a trench and major excavation may be your only option.

Factors Impacting the Cost of Sewer Line Replacement or Repair


Length of Line

The length of your line affects cost because of material amounts, labour costs and how much time the project will take to complete.



If your yard has multiple concrete slabs, fences,
structures and trees to contend with,
this will elevate your costs.


The Extent of Problems

A small, localized repair won’t cost too much or take too much time, but extensive damage could be a multi-day job and that gets more expensive.


Cleaning and Restoration

A serious sewer leak could lead to health hazards in your home or backyard, specifically if there’s a backup. Professional cleaning and extra precautions may add cost to your total.

Tips to Protect Your Sewer Lines

Nobody can ensure total sewer protection forever, but there are some steps you can take to ensure durability:

Sewer line inspections: For a small fee each year, we can investigate your system and catch any small problems before they can turn into costlier issues.

Tree removal: Stop roots from invading your sewer line before they have a chance to start. Consult with us about which trees should be removed from your yard to minimize risk.

Proper sewer system usage: Only flush human waste and toilet paper. Do not flush other hygiene products, baby wipes or kitchen grease.

Pros and Cons of Sewer Line Repair


  • Improve the system: New pipes can reduce the risk of clogging and improve drainage.
  • Reduce maintenance: Replaced sewer lines need less work than older ones.
  • Increase home value: An updated and maintained sewer system looks good to prospective buyers.


  • High cost: Replacing your sewer lines can be an expensive home project.
  • Time-consuming: In some cases, a major sewer line replacement can take several days.
  • Unforeseen problems: Once excavation begins, other problems may be discovered that add time and cost to the project.


Several factors determine the cost of sewer replacement. The most affordable option is a trenchless repair which requires little digging. Most of the cost associated with sewer replacement is not the materials and machinery required to make repairs, but the lawn damage, uprooting, and landscaping that occurs. Homeowner insurance does not always cover the post of sewer line repair so it is important to check with your provider.

Barring unforeseen factors such as tree root obstruction, a clay sewer line could last up to 60 years, while a cast-iron or ABC/PVC line could last up to 100 years.

If your cast iron pipes are rusting and breaking down, it’s recommended to swap it out for PVC as cast iron repairs are more expensive.

Broken sewer pipes can release toxic fumes into the air which can be extremely harmful to the home occupants’ health.

It’s very unlikely that home insurance will cover a broken sewer line unless it’s damaged through human error, for example, by neighbours doing construction.

This happens when the shower’s P-trap has emptied of water or it could be a sign that your drain is clogged.

If your sewer line is clogged, a flushed toilet will allow contaminated air and fumes to enter the home.

If there are blocked drains, empty P-traps from evaporation or a sewer clog, this will make your home smell like sewer sometimes.
