Need an underground water line replacement?
Cheap Plumber is trusted for professional pipe repair and replacement, including lead water line replacement for older properties.

Many older homes, especially those built before the 1950s, may still have lead water service pipes. Over time, these pipes can affect drinking water quality and may expose your household to harmful lead particles. Replacing outdated water service lines is an important step toward improving the safety, reliability, and overall performance of your plumbing system.

At Cheap Plumber, we have extensive experience with water service replacement in Toronto and the GTA. Our licensed professionals handle the work efficiently, help minimize disruption to your property, and provide reliable solutions that fit your needs and budget. We focus on safe, code-compliant workmanship so you can have greater confidence in your home’s water supply.

Over time, water lines can wear out, corrode, crack, or become damaged, especially in older homes. Some of the most common signs that water line replacement may be needed include:

• Low water pressure
  Weak water flow in showers, sinks, or appliances may point to corrosion, buildup, or damage inside the pipe.
• Discoloured or unpleasant-smelling water
  Rust-coloured water or unusual odours can be a sign of aging pipes, sediment buildup, or possible contamination.
• Higher water bills
  A sudden increase in your water bill without a change in usage may suggest a hidden leak in the water line.
• Frequent pipe leaks
  Recurring leaks, especially in older plumbing systems, often indicate that the pipe is deteriorating and may need replacement rather than another temporary repair.
• Musty odours or mould growth
  Persistent damp smells or visible mould can be caused by hidden leaks behind walls, under floors, or near the foundation.
• Flooding or standing water in the yard
  Wet spots, pooling water, or unusually soft ground near the water line can signal an underground leak or burst pipe.
• Frozen or burst pipes
  Older or poorly protected pipes are more vulnerable during cold weather and may crack or burst when temperatures drop.
• Shifting soil or tree root damage
  Ground movement and invasive tree roots can crack, misalign, or block underground pipes over time.

If you notice any of these warning signs, it is best to have your water line inspected as soon as possible using a drain video camera inspection to confirm the cause. Early action can help prevent more serious damage, costly repairs, and interruptions to your water supply.

Water Line Replacement Costs

The cost of replacing a water line in Toronto can vary depending on several factors, including the type of pipe used, the length of the line, and the installation method.

Per Linear Foot: 

Water line replacement typically costs between $50 and $250 per foot, depending on the pipe material and the complexity of the job.

Total Estimated Cost:

The total cost to replace a water main or water line can range from $1,500 to $5,000, including labor, materials, and any necessary permits.

Factors Affecting Water Line Replacement Cost

• Length of the Line: The longer the water line from the street to your home, the higher the cost. A longer sewer line will increase both labor and material costs.
• Type of Pipe: The type of material used for replacement, such as PEX, can impact the overall cost. PEX is durable and cost-effective, making it a great choice for water service line replacements.

Installation Method: If you prefer a less disruptive option, we offer trenchless water line replacement. This method avoids digging up your yard and can save you money by reducing excavation and landscaping costs.

Water line replacement should always be handled by licensed professionals. DIY repairs can cause costly damage. With Cheap Plumber, your replacement will be done efficiently, correctly, and with transparent pricing.
