Professional Toilet Repair Services

Toilets have several components working together every time you flush, including the fill valve, flapper, flush valve, handle, chain, refill tube, seals, and water supply connection. When one component wears out or stops working properly, it can affect the entire toilet.
Our technicians diagnose the source of the problem before recommending a repair, so you know what needs to be fixed and why.

Running Toilet Repair

If your toilet continues running long after you flush, there may be a problem with the flapper, fill valve, float, chain, or another internal component.
A running toilet is easy to ignore because the water stays inside the fixture, but that constant flow can waste a significant amount of water. Canadian households used an average of 223 litres of residential water per person per day in 2021, making unnecessary water loss worth addressing as soon as you notice it.
Our running toilet repair service identifies the faulty component and restores the proper fill and shut-off cycle.

Leaking Toilet Repair

A leaking toilet may leave water around the base, drip from the tank or supply connection, or leak internally without leaving visible water on the floor.
Depending on the source, leaking toilet repair may involve replacing a worn seal, tightening or replacing connections, repairing tank components, or correcting an installation problem.
Water around the base of your toilet should not be ignored. If the leak continues, moisture can affect flooring and surrounding materials. Our technicians can determine where the water is coming from and complete the appropriate repair.

Toilet Flush Repair

Does the handle need to be held down? Is the flush weak or incomplete? Does the toilet take too long to refill?
Problems with the handle, chain, flapper, flush valve, fill valve, or water level can all affect flushing performance. Our toilet plumbers can inspect the components inside the tank, identify what is interfering with the flush cycle, and repair or replace worn parts.

Clogged Toilet Repair

Some minor toilet clogs can be cleared with a plunger. Recurring clogs, slow flushing, backups, or toilets that repeatedly overflow may point to a deeper problem.
If a blockage cannot be cleared easily, avoid repeatedly flushing the toilet. This can cause the bowl to overflow and spread water across your bathroom.
Our team provides professional clogged drain services and can determine whether the problem is isolated to the toilet or related to the drain line.

Toilet Replacement & Installation

Not every toilet needs to be replaced. If the fixture is in good condition and the problem involves a replaceable component, a repair may be the most practical solution.
For an older, damaged, inefficient, or frequently problematic toilet, replacement may make more sense. Natural Resources Canada identifies toilets using 4.8 litres per flush or less as water-saving fixtures. In 2023, 48% of Canadian households reported having a low-volume toilet, including 50% of Ontario households.

If replacement is the better option, our team can remove your existing fixture and professionally install the new toilet to help prevent leaks, movement, and performance problems.

Should You Repair or Replace Your Toilet?

A toilet can last for many years, and a problem with one component does not necessarily mean the entire fixture needs to go.

Repair is often appropriate when the toilet itself is in good condition and the problem involves a replaceable component such as the flapper, fill valve, handle, seal, or supply connection.
Replacement may be worth considering when:
  1. 1
    The tank or bowl is cracked
  2. 2
    The toilet requires frequent repairs
  3. 3
    Clogs continue despite repairs
  4. 4
    The fixture is loose or unstable because of damage
  5. 5
    The toilet uses considerably more water than newer models
  6. 6
    Repair costs are becoming unreasonable compared with replacement
24%of annual household water use
63%less water for flushing
Water efficiency can also be a consideration. Statistics Canada has reported that toilets account for approximately 24% of average annual household water use based on a study of selected Canadian and U.S. cities. A family of four using a low-volume toilet can use approximately 63% less water for flushing than a family using a traditional model.
If you are unsure which option makes sense, we can inspect the toilet and explain whether repairing or replacing it offers better long-term value.

Common toilet questions

Toilet Repair FAQs

Why does my toilet keep running after I flush it?

A toilet that keeps running often has a worn flapper, faulty fill valve, improperly adjusted float, chain problem, or another issue inside the tank. A plumber can identify which component is causing the water to continue flowing and replace or adjust it.

Why is my toilet leaking around the base?

Water around the base can be caused by a failed seal, loose toilet, damaged connection, condensation, or another plumbing issue. Stop using the toilet if the leak is significant and have it inspected before water damages the surrounding flooring.

Can a plumber fix a toilet that keeps clogging?

Yes. Recurring toilet clogs can be caused by an obstruction in the toilet, a problem with the fixture’s flushing performance, or a blockage farther down the drain line. A plumber can determine the source instead of repeatedly treating the symptom.

Is it better to repair or replace an older toilet?

It depends on the condition of the fixture, the type of problem, repair frequency, and water efficiency. A relatively simple component failure may only require repair, while cracks, recurring problems, or an inefficient older fixture may make replacement more practical.
