Here’s a complete guide to the repair and maintenance services we offer.
Leak Detection & Pipe Repair in Toronto
Water leaks are one of the most common reasons Toronto homeowners call for plumbing repair in Toronto. A small leak behind a wall or under a floor can go unnoticed for weeks, causing structural damage, mold, and inflated water bills.
We provide professional leak detection and pipe repair services, including:
- Visual and pressure-based leak detection — We test your system to identify the source of the leak, even when it’s hidden behind walls or under concrete.
- Copper pipe repair and soldering — Pinhole leaks and corroded joints in copper supply lines are common in older Toronto homes. We repair or replace the affected section with proper soldered fittings.
- Supply line replacement — If your home has aging galvanized steel pipes, we can replace sections or full runs with modern copper or PEX piping.
- Shut-off valve repair and replacement — Faulty shut-off valves can make it impossible to isolate a leak. We replace old gate valves with reliable ball valves for better control.
If you notice damp spots on walls, unexplained increases in your water bill, or the sound of running water when nothing is on, call us at (416) 949-2919 for a leak assessment.
Clogged Drain & Toilet Repair in Toronto
A clogged drain or toilet is more than an inconvenience — it can lead to sewage backups, water damage, and unsanitary conditions. We handle all types of drain and toilet repair in Toronto, from simple clogs to complete fixture replacements.
Our services include:
- Toilet unclogging and repair — We clear stubborn toilet blockages and repair running toilets, leaking seals, broken flanges, and faulty fill valves.
- Kitchen drain cleaning — Grease and food debris buildup is the most common cause of kitchen drain clogs. We snake the line and clean the trap to restore flow.
- Bathroom drain cleaning — Hair and soap scum accumulate in shower and sink drains over time. We remove the blockage and check for deeper issues.
- Floor drain clearing — Basement floor drains can back up during storms if they’re clogged with debris or sediment.
For recurring drain issues, we recommend a camera inspection to identify the root cause, whether it’s root intrusion, pipe damage, or buildup deep in the line.
Frozen Pipe Repair in Toronto
Toronto winters regularly bring temperatures well below freezing, putting exposed or poorly insulated water pipes at risk. A frozen pipe can block your water supply entirely, and if the pipe bursts, it can cause catastrophic water damage.
Our frozen pipe repair in Toronto includes:
- Safe pipe thawing — We use professional heat application methods to thaw frozen pipes without damaging them.
- Burst pipe repair — If a frozen pipe has already split, we isolate the damage and repair or replace the affected section immediately.
- Insulation recommendations — After the repair, we identify vulnerable pipes and recommend insulation solutions to prevent future freeze events.
If you turn on a tap in winter and nothing comes out, or you hear a faint hissing sound from a wall, call us immediately. Time is critical with frozen pipes — the sooner we respond, the less damage occurs.
Tap & Faucet Repair in Toronto
A dripping faucet wastes thousands of litres of water per year and increases your utility bills. More importantly, the constant dripping can stain sinks, damage countertops, and indicate worn internal components that will eventually fail completely.
We handle all types of tap repair in Toronto:
- Cartridge and ceramic disc replacement
- O-ring and washer replacement for compression faucets
- Spout and handle tightening or replacement
- Supply line connection repairs
- Full faucet replacement when repair isn’t cost-effective
If you need a new faucet installed rather than repaired, see our Plumbing Installation Toronto page for details.
Water Heater Repair in Toronto
No hot water is one of the most urgent household plumbing problems. Whether you have a traditional tank or a tankless system, we provide fast water heater repair in Toronto for all makes and models.
Common water heater issues we fix:
- No hot water — Could be a failed heating element, thermostat, or gas valve issue.
- Inconsistent temperature — Often caused by sediment buildup in the tank or a failing mixing valve.
- Leaking tank — A leak from the tank itself usually means the unit needs replacement. A leak from fittings or the pressure relief valve may be repairable.
- Strange noises — Popping, rumbling, or banging sounds typically indicate sediment buildup that needs flushing.
- Pilot light issues — Gas water heaters can have thermocouple or gas valve problems that prevent the pilot from staying lit.
We repair both tank and tankless systems. If your water heater is beyond repair, we provide same-day replacement options.
Sump Pump Repair in Toronto
A failing sump pump leaves your basement vulnerable to flooding during the next storm. We provide emergency sump pump repair in Toronto for all pump types, including submersible, pedestal, and battery backup systems.
Common sump pump problems we fix:
- Pump won’t turn on or won’t shut off
- Float switch stuck or jammed
- Motor running but not pumping water
- Excessive noise or vibration
- Discharge line blockage or disconnection

Emergency Plumbing Repair in Toronto
Some plumbing problems can’t wait until morning. A burst pipe, a sewer backup, or a flooding basement needs immediate professional attention. We provide emergency plumbing repair in Toronto with fast response times.
When to call for emergency service:
- Water actively flowing where it shouldn’t be
- Sewage backing up into your home
- No water supply to the entire house
- Gas smell near a water heater or gas line
- Sump pump failure during a storm
Emergency tip: If you have an active water leak, locate your main water shut-off valve and turn it off before calling us. This minimizes damage while you wait for our team to arrive. In most Toronto homes, the shut-off valve is in the basement near the front wall where the water line enters the house.
Preventive Plumbing Maintenance in Toronto
The best way to avoid costly emergency repairs is regular preventive maintenance. We offer comprehensive plumbing maintenance services for Toronto homeowners who want to stay ahead of problems:
- Annual plumbing inspection — We check all visible pipes, fixtures, water heater, sump pump, and shut-off valves for signs of wear or impending failure.
- Water heater flush — Annual flushing removes sediment buildup that reduces efficiency and shortens the unit’s lifespan.
- Sump pump testing — We test the primary pump and battery backup to make sure they’re ready for storm season.
- Fixture maintenance — Tightening connections, replacing worn washers, and checking for slow leaks at every fixture.
Regular maintenance catches small issues before they become expensive emergencies. The City of Toronto’s Basement Flooding Protection Subsidy now includes up to $500 for a professional home plumbing assessment — making preventive maintenance more affordable than ever.
