Who This Service Is For

Galaxy Plumbing's pipe replacement service is built for:

  • Owners of homes built between 1940 and 1995 where Poly-B, galvanized steel, or lead pipes may be present and approaching or past their service life
  • Homeowners with a Poly-B system over 20 years old that has experienced joint failures or visible fitting deterioration and needs replacement before the next leak occurs inside a wall or ceiling
  • GTA homeowners with consistently reduced water pressure that cannot be explained by municipal supply conditions, often traced to a corroded galvanized interior or an undersized service line
  • Owners of pre-1955 Toronto or older Mississauga properties with confirmed lead service lines, where replacement is both a health priority and supported by a City of Toronto cost coverage program
  • Homeowners undertaking a renovation that exposes aging pipe runs, making comprehensive replacement practical while walls and ceilings are already open

If you are unsure what pipe material your home contains or whether replacement is the right decision, contact Galaxy Plumbing for an on-site assessment before committing to any scope.

What This Service Includes

Galaxy Plumbing's pipe replacement service covers the full scope of residential pipe system work:

  • Poly-B pipe replacement with copper or PEX based on your home's configuration and the complexity of the pipe runs; both materials are code-compliant and compatible with GTA municipal water chemistry
  • Galvanized steel pipe replacement as a full-system project, with condition assessment of accessible pipe runs and realistic staging options for minimising disruption
  • Lead service line replacement on the private-property side, with full knowledge of the City of Toronto lead pipe replacement program and coordination requirements for eligible properties
  • Water service line upgrades from half-inch to three-quarter-inch or one-inch service connections, including permit acquisition and municipal curb stop coordination; see our water lines service for the full supply-side scope
  • Full home repiping replacing the entire supply distribution system or a major portion of it, planned in sections to maintain water service throughout the project
  • Drain camera inspection to assess existing pipe condition before scoping any replacement work
  • Water leak detection to identify active issues in Poly-B or aging systems before they cause significant damage
  • Water filtration integration where lead line replacement or pipe material changes create an opportunity to address water quality at the same time
  • Before-during-after photo documentation on every project, with wall and ceiling surfaces restored to the condition they were found

How It Works

Step 1: Assessment and Camera-Confirmed Scope

Contact Galaxy Plumbing to schedule an on-site pipe assessment. Our technicians identify the pipe material present, use drain camera inspection where needed to confirm condition in inaccessible runs, and photograph the existing system before any recommendation is made. You receive a clear scope with a specific replacement approach before committing to any work.

Step 2: Upfront Pricing and Project Planning

You receive a written estimate specifying the replacement scope, the pipe material being used, the project timeline, and whether any permit or municipal coordination is required. For full repiping projects, the work plan is presented in sections so water service is maintained throughout. No work begins without your approval.

Step 3: Replacement, Documentation, and Final Inspection

Every replacement is completed to Ontario Building Code standards. Affected walls, ceilings, and surfaces are restored to the condition we found them. The completed system is documented with before-during-after photos. For lead line replacement, City of Toronto program paperwork is handled by our team.

Pipe Replacement by Material Type

Poly-B Pipe Replacement

Polybutylene pipe was installed in a significant number of Canadian homes from approximately 1978 to 1995. Its failure mechanism is well documented: the material oxidises when exposed to chlorine and chloramine compounds in municipal water, causing the pipe to become brittle at fittings and joints. Failures are typically internal and not visible until the pipe actually leaks, often inside a wall or ceiling.

In GTA homes, Poly-B deterioration tends to accelerate after the 20 to 25-year mark. Failures typically begin at compression fittings and acetal plastic joints rather than along the pipe body. If your home has Poly-B and has not yet experienced a failure, that does not mean the system is sound. Galaxy Plumbing replaces Poly-B systems with copper or PEX depending on the home's configuration and pipe run complexity. Our blog post on when to replace plumbing pipes covers the Poly-B timeline in detail.

Galvanized Steel Pipe Replacement

Galvanized steel supply lines were standard in GTA homes built from the 1940s through the early 1970s. The zinc coating that protects the steel interior corrodes progressively over time, depositing scale on the pipe walls and narrowing the interior diameter. The result is reduced water pressure, discoloured water, and eventually section failures, typically at 40 to 60 years of age.

Galvanized steel pipe replacement is typically a full-system project because a pipe system at the point of failure in one location is usually at or near that point throughout. Our technicians assess the condition of accessible pipe runs and provide a replacement scope with realistic staging options.

Lead Service Line Replacement

Lead water service lines were used in Toronto and older Mississauga properties built before approximately 1955. Lead in drinking water poses serious health risks, particularly for children and pregnant women. Health Canada confirms there is no safe level of lead exposure from drinking water.

The City of Toronto's lead service line replacement program includes partial financial support for the private-property side of the replacement. Our water filtration service also provides immediate water quality protection at the kitchen tap while a full service line replacement is being arranged. Contact us to discuss your specific property and eligibility.

Water Service Line Upgrades

Many GTA homes built before 1980 were connected to the municipal supply with a half-inch water service line. Modern households with multiple bathrooms, dishwashers, irrigation systems, and high-flow fixtures often experience chronic pressure deficiency that originates at the undersized service connection. Upgrading to a three-quarter-inch or one-inch service line resolves this at the source. Our team manages permit acquisition, municipal coordination, and the full connection scope.

Benefits

Choosing Galaxy Plumbing for pipe replacement in Mississauga means:

  • Camera-confirmed scope before any wall is opened or work is committed
  • Honest material recommendation based on your home's configuration, not on which option is more convenient to install
  • Full project documentation with before-during-after photos suitable for insurance records and home resale
  • City of Toronto lead pipe program navigation for eligible properties
  • Upfront pricing confirmed after assessment and before work begins
  • Minimal disruption through staged project planning that maintains water service throughout

Our blog post on when to replace plumbing pipes covers how each pipe material type ages and what the signs of end-of-life look like in GTA homes.

"Rob cares. Anytime we had questions, he would walk us through beginning to end."
"Rob and Galaxy plumbing were fantastic."
Nancy Pascua ★★★★★
Just fantastic service. Spent extra time trying to figure out a mysterious water leak. Super professional and knowledgeable. Gave me options and time to decide how to proceed. Would use again and would recommend to anyone.
Bev Battaglia ★★★★★
Fantastic job by Galaxy Plumbing!  Appreciated the professionalism and informative service from this team.  I had a toilet and sink back up issue which the technician was able to come and resolve the same day I called.  At the same time, recommendations were shared to prevent similar issues in the future.  Great attitude and top notch workmanship!
Jason Lobo ★★★★★
Rob's service from start to finish was exceptional. Spoke with him about getting a dripping bathtub faucet fixed. Walked me through how to remove the valve cover. Also correctly guesses that it was a water cartridge issue.  Booked a plumber the next day and sent me a text with the ETA. The communication through out was fantastic. For some one who has never booked a plumber for a smaller job, understand that it's not cheap. And you have to consider the cost of parts if not covered under warranty. Would definitely recommend Rob and use his company again if needed.

Maz Mozaffari ★★★★★
This is the 2nd time we've used Rob and his company Galaxy Plumbing for various plumbing needs. They have always been very responsive, helpful, and knowledgeable.  In our most recent call out, Rob was very thorough in explaining the potential causes to our new plumbing issues, and provided a number of possible solutions without trying to pressure us to take on any unnecessary work. He was very careful to properly check and verify that the issue was resolved before he left. This was much appreciated.  We would not hesitate to use Rob and his company again in the future.
Louise P ★★★★★
I had an issue with my kitchen faucet and called Galaxy Plumbing because I had seen their van in my neighbourhood. Rob returned my call and came to have a quick look and assess the situation. He ended up taking the time to fix the faucet while he was here. He was very responsive, professional and friendly.

Signs That Pipe Replacement Is the Right Decision

These conditions in a Mississauga or GTA home suggest replacement is the more practical long-term path than continued repair:

  • A Poly-B system over 20 years old with documented joint failures or visible fitting deterioration
  • Galvanized steel supply lines with consistently reduced water pressure across multiple fixtures
  • Recurrent leaks at multiple locations in the same pipe run within a short period
  • Confirmed lead service lines in a pre-1955 Toronto or older Mississauga home
  • Discoloured or rust-tinted water from hot or cold taps indicating internal pipe corrosion
  • A home renovation that exposes aging pipe runs that would otherwise remain inaccessible for years

Our water leak detection service can identify active issues before they cause significant damage where any of these conditions are present.
