25-year workmanship warranty
Every job Tornado Plumbing & Drains completes in Toronto and the GTA — repair, install, replacement, drain work, sewer work, fixture work — is backed by a 25-year workmanship warranty. The written terms are provided with every quote. If our work fails within 25 years of the install date, we come back and make it right.
Repair the toilet you have, or replace it right
Most calls split two ways: a part failed (fill valve, flapper, supply stop, wax ring) and the toilet is worth saving, or the bowl is cracked, the flange has rotted, or you want a low-flow upgrade and replacement makes more sense. We diagnose the actual cause before quoting, because a toilet that rocks or leaks at the base is usually a flange or wax-ring problem, not a reason to throw out the bowl. If the flush stays weak after the tank parts check out, the real holdup can be the drain branch — and we can scope it with a drain camera inspection instead of guessing.
Common toilet symptoms
| Symptom | Likely cause | Fix |
|---|---|---|
| Toilet keeps running | Worn flapper, fill valve, or chain | Replace flapper or fill valve. |
| Water on the floor at the base | Failed wax ring or cracked flange | Pull the toilet, replace the wax ring, repair flange if needed. |
| Weak or incomplete flush | Clogged jets, low fill, partial blockage | Clean jets, adjust fill, snake if needed. |
| Loose toilet rocking | Loose flange bolts or cracked flange | Re-anchor or replace the flange. |
| Ceiling stain in room below | Long-term wax ring leak | Pull and reset toilet, repair ceiling water damage. |
| Whistling or hissing | Failing fill valve | Replace fill valve. |
What's included
- Diagnosis of the real fault — running water, weak flush, base leak, rocking bowl, or a tank that won't fill — so you're not paying to replace parts that aren't broken
- Internal repairs done with quality parts: fill valve, flapper, flush valve, tank-to-bowl gasket and bolts, and a new supply stop and braided line if the shutoff is seized or weeping
- Base and seal work: pulling the bowl, replacing the wax ring or rubber seal, repairing or swapping a corroded or broken flange, and re-leveling and shimming so the toilet sits solid and stops rocking
- Full toilet installation: removal and disposal of the old unit, setting the new bowl and tank, leak-testing the supply and base, and caulking the base to code
- Cleanup of the work area and the old toilet hauled away, with the floor checked for any water damage under the previous unit
- Written 25-year workmanship warranty on the labour we perform
Toilet cost
Internal parts (fill valve, flapper) are the lowest cost. Pulling the toilet for wax ring or flange repair is mid-range. Full toilet installation depends on whether the toilet is homeowner- or contractor-supplied and whether the rough-in is standard.
What to share when you call
- Symptom and how long it has been happening.
- Brand and age of the toilet if known.
- Whether the floor below has any water staining.
- Whether the bowl rocks.
- Photos of the toilet and surrounding floor.
- Whether you have a replacement toilet ready.
Toronto context
Toilet replacement makes more sense than repair when the wax seal has failed twice, when the tank crack is structural, or when the bowl has been chipped at the rim. New 4.8 LPF or dual-flush units cut Toronto water bills meaningfully on multi-occupant homes. We replace the flange when the floor has been built up over time.
What to confirm before approving toilet work
- Wax ring leaks should be fully diagnosed — flange condition matters.
- Replacement should match the existing rough-in dimension or include adjustment.
- Shutoff and supply line should be tested when the bowl is pulled.
Useful info on the call: symptom, age, floor staining, and whether the bowl rocks.
Frequently asked questions
Why does my toilet keep running?
Most often a worn flapper that does not seal, a misadjusted chain, or a failing fill valve. The fix is usually inexpensive parts.
Why is there water at the base?
Most often a failed wax ring or cracked flange. Both require pulling the toilet to repair properly. A wax ring leak that has been ignored often shows up as a stain on the ceiling below.
Should I replace my old toilet?
If the toilet is older than 1996, it is using more water per flush than current code. Replacement saves on water bills and usually performs better.
Can you install a toilet I purchased?
Yes. Tell us the brand and model when booking so the right wax ring, supply line, and tools are on hand.
How much does toilet repair cost in Toronto?
Most toilet repairs start at $150 for internal parts work like a fill valve or flapper, with the exact price confirmed in writing after we diagnose the cause. Base leaks, flange repairs, or a full replacement cost more because they involve the wax seal, mounting, or a new fixture. We quote before any work begins.
What does toilet installation cost and what's included?
A standard toilet installation in Toronto covers removing the old unit, setting the new toilet on a fresh wax seal, connecting the supply, and testing for leaks. We confirm the price in writing first and can install a toilet you purchased or supply one. Book online or call 647-784-8448 for a written quote.

I D
February 2022“I had an urgent toilet leak, and since my elderly mother depends on it, this was a real emergency. Serhiy from Tornado Plumbing & Drains responded quickly, even while working across the city. He assessed the issue, explained everything clearly, and returned early the next morning to fix it before his larger job. Professional, reliable, and highly skilled. If you need fast, trustworthy plumbing or toilet repair, I highly recommend Tornado Plumbing & Drains.”

May 2025“I highly recommend Serhiy. I have used him several times, and he always does quality work. He recently replaced a toilet, faucet, and house shut-off valve, all of which had leaks and were faulty. He knows what he is doing - He is licensed, experienced, efficient, and pays attention to details. His pricing is very fair, and unlike some others, the price doesn't go up based on the area you live in. All this is hard to find in professionals. Someone honest (he won't fix things that don't need repair to create work) and who takes pride in a job well done. I will definitely call him again for future plumbing needs.”
