Toilets are the most-used plumbing fixture in any home and one of the most reliable — a quality toilet can run for 20+ years with nothing more than occasional flapper and fill valve replacement. Most of the toilets we replace in Kanata are getting replaced for cosmetic upgrade or efficiency, not because they failed.
The most common toilet service calls are: a constantly running toilet (usually flapper), a weak flush (usually fill valve or partially clogged jet), or a leak at the base (usually wax seal, sometimes a cracked tank). All three are typically same-visit fixes.
Common signs you need this service
- Toilet runs constantly or cycles randomly
- Weak flush that doesn't clear the bowl
- Toilet rocks when sat on
- Water around the base after flushing
- Visible cracks in the tank or bowl
- Replacing for a comfort-height upgrade or low-flow efficiency
The 'running toilet' diagnosis
A toilet that runs constantly is almost always one of three things. The flapper (the rubber disc at the bottom of the tank that lifts when you flush) has hardened or warped and isn't sealing — replace the flapper, $15 part, 10-minute job. The fill valve (the tower on the left side of the tank that refills after flushing) isn't shutting off properly — replace the fill valve, $25 part, 20-minute job. Less commonly, the flush valve (the larger assembly the flapper sits on) is cracked or has a worn seal — that's a tank-out repair, $80 part, 45 minutes. We diagnose in 5 minutes and quote the right answer.
Weak flush
If your toilet flushes but the bowl doesn't fully clear, the most common cause is mineral build-up in the rim jets (the small holes around the rim that direct water into the bowl). Kanata's moderately hard water deposits scale that partially blocks the jets, reducing the swirl and force of the flush. A descaler treatment usually restores it. If descaling doesn't help, the next causes are: fill valve not delivering enough water to the tank (set the water level higher), or a partial blockage in the trapway of the bowl itself (auger usually clears it).
Leaks at the base
A leak at the base of the toilet — water visible on the floor after flushing — is almost always a failed wax seal between the toilet and the floor flange. The fix is to remove the toilet, scrape off the old wax, install a new wax seal, and reseat the toilet. The complication is the floor flange itself: if it's damaged, rusted, or below the finished floor level, it needs repair (a flange extender or a flange repair ring) before a new wax seal will hold long-term. We assess the flange every time we reseat a toilet.
Choosing a new toilet
If you're replacing, the things that matter for long-term satisfaction are: flush performance (Toto is the leader; American Standard Champion is excellent value), comfort height (17-19 inches to seat — easier on adults than the traditional 15-inch), elongated bowl (more comfortable than round front for most adults), and easy-to-clean design (skirted trapway, smooth surfaces). Dual-flush is fine but a quality single-flush 1.28 GPF often outperforms a mediocre dual-flush. Don't buy the cheapest big-box no-name — toilet repair parts are brand-specific, and obscure-brand parts are hard to find.
The supply shut-off
Just like with faucets and washing machines, the shut-off valve behind the toilet is often original to the home and may be seized. We strongly recommend replacing original multi-turn screw-stem stops with quarter-turn ball valves whenever we're already doing toilet work. It's a $20 part, takes 15 minutes, and turns a future emergency into a non-event.
Our process
- 1
Diagnose
Most issues trace to flapper, fill valve, flush valve, or wax seal. We identify the actual cause.
- 2
Quote both options
If your toilet is in good shape, repair is almost always cheaper. If it's old or low-end, replacement may be the right answer. You get both numbers.
- 3
Repair or replace
Repairs are usually one-visit, under an hour. Replacements are 90 minutes including disposal of the old unit.
- 4
Test thoroughly
We flush 5+ times, check for any base leak, verify the fill cycle is silent and stops cleanly.
What's included
- Diagnostic and repair recommendation
- Flapper, fill valve, or flush valve replacement with quality parts
- New wax seal and closet bolts for any reseating
- Toilet shut-off valve replacement if seized
- Removal and disposal of old unit on replacements
- Workmanship warranty
What affects the price
Repair vs replace
A $30 part fixes 80% of toilet problems. New installs run higher because of the toilet itself plus install labour.
Flange condition
If the floor flange (the metal/PVC ring the toilet bolts to) is damaged or rusted, it needs repair before a new wax seal will hold.
Flooring around the toilet
Tile, hardwood, vinyl plank — each affects how cleanly we can reseat without damage.
Why Kanata homeowners choose us
- Honest diagnosis — we don't push a replacement when a $30 part will fix it
- We use quality parts (Korky, Fluidmaster) — never generic 'fits-most' kits
- We always replace the wax seal on any reseating, even if the old one looked fine
- We test the flush 5+ times before leaving
Most Kanata toilets are 1.6 GPF (low-flow) units installed during builds from 1995 onward, or newer 1.28 GPF dual-flush units. The 1.6 GPF generation is in its third decade and starting to need fill valve and flapper replacements. The dual-flush units have a fussier mechanism — when they go, they go in ways that need a real diagnosis.

Toilet repairs (flapper, fill valve) are genuinely DIY-friendly with a YouTube video and a $15 part. New toilet installs are doable but the wax seal is the gotcha — it has to be set perfectly the first time, and you can't really 'test' it without flushing 50 times and waiting. Most DIY install leaks are bad wax seals.
