Homeowners With Existing Hydronic Heating Systems

Hot water radiator service is primarily needed by homeowners in older GTA properties originally built with hydronic heating, including houses from the 1920s through the 1980s that use cast iron or steel panel radiators connected to a central boiler. Renovation projects in these homes often require radiator relocation, replacement, or valve upgrades. Galaxy Plumbing also works with homeowners upgrading from cast iron boilers who want to retain hydronic radiators as part of the new heating system.

Condo Corporations and Multi-Residential Buildings

Multi-residential buildings with central boiler systems and individual suite radiators require a mechanical contractor experienced with building-wide hydronic systems. Galaxy Plumbing services radiators across condo and apartment buildings in the GTA, handling individual suite radiator repairs, building pipe replacements, pump service, and boiler maintenance as part of a coordinated mechanical service arrangement.

How Does the Galaxy Plumbing Radiator Service Process Work?

Galaxy Plumbing Inc. follows a structured four-step process for every radiator installation and repair to ensure the system is balanced, properly connected, and performing as expected before the job is closed.

Step 1: Assessment

A licensed Galaxy Plumbing technician inspects the radiator, the connecting pipework, and the boiler system to identify the fault or confirm the installation requirements. Findings are documented and explained clearly to the homeowner before any recommendation is made.

Step 2: Upfront Pricing

A written quote is provided before any work begins. The full scope of work, including any pipe repairs, valve replacements, or boiler-side adjustments needed, is itemized and confirmed with the client. No work starts without approval.

Step 3: Expert Execution

Installation or repair is completed by licensed technicians with direct experience on hydronic heating systems. All pipe connections are made to code, new radiator units are pressure tested, and valve work is completed to the manufacturer specification.

Step 4: Quality Assurance

The system is bled, balanced, and tested across all radiator zones after the work is complete. The technician confirms each radiator is heating correctly and completes a walkthrough with the homeowner. Before-during-after photo documentation is provided on every job.

It's all love, baby.

We love what we do.
It's pretty much all because of you.

"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.

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.

What Are the Warning Signs That Your Hot Water Radiators Need Service?

Hydronic radiator systems give clear signals when service is needed. Recognizing these signs early prevents more disruptive and expensive repairs to the system.

  • One or more radiators remain cold while others in the same system are warm, indicating air lock, valve failure, or flow imbalance
  • Banging, knocking, or gurgling sounds from a radiator during heating cycles, which typically indicate trapped air or water hammer
  • Water staining, rust marks, or visible moisture at the base of a radiator or along connecting pipes
  • A radiator that is warm at the bottom but cold at the top, which is a classic sign of trapped air requiring bleeding
  • The boiler running continuously without the building reaching the set temperature
  • Radiator valves that are stiff, stuck, or no longer adjusting the heat output of the unit
  • Persistent cold spots in rooms that have a functioning radiator, suggesting the unit is undersized or partially blocked
  • The system has not been bled or balanced in more than two to three years and room temperatures have become uneven

Why Do GTA Homeowners Choose Galaxy Plumbing for Radiator Installation and Repair?

Galaxy Plumbing Inc. is locally owned and operated by Roberto Fraschini, who built the company with a focus on hydronic heating systems alongside full plumbing service. Hot water radiator work sits at the intersection of plumbing and HVAC, requiring competency in both the pipe connections and the boiler system that drives them. Galaxy Plumbing covers both under one roof, eliminating the coordination problems that arise when a plumber handles the pipes and a separate HVAC contractor handles the boiler.

All gas work connected to the boiler feeding a radiator system is performed by TSSA certified gas technicians licensed under Ontario Regulation 212/01. The team provides boiler service alongside radiator work when the boiler requires attention, and can address heating pipe leaks, pump issues, and zone control faults as part of the same service visit.

Before-during-after photo documentation is completed on every job. Upfront pricing is confirmed before work begins, and 24/7 emergency response is available for active radiator leaks or heating failures that need urgent attention during winter months.
