Toilet Repair & Replacement
Rebuilds, wax seals, clogs, and new installs across Mukilteo, Everett, and Snohomish County
Stollwerck Plumbing & Sewer repairs, rebuilds, and replaces toilets across Mukilteo, Everett, Edmonds, and Lynnwood. Toilets are the second most common job in our records after water pressure. A standard two-piece rebuild runs about $399 to $427 plus the $89 dispatch fee, and most are finished in a single visit.
What We Do
Rebuild an Existing Two-Piece Toilet
New fill valve, new flapper, new supply line, and the flush valve gasket if it needs one. This is the right repair for a toilet that runs, fills slowly, or flushes weakly but is otherwise sound — which describes most of the toilets we are called out to.
Pull and Reset the Wax Seal
A toilet that rocks, weeps at the base, or leaves a stain on the ceiling below is usually a failed wax seal rather than a failed toilet. We pull it, clean the flange, set a new seal, re-secure the closet bolts, and check that it sits flat.
Clear a Plugged Toilet
Closet auger first, from the bowl. If it does not clear, the obstruction is past the trap and it becomes a drain problem, not a toilet problem — and we tell you that rather than augering the same bowl three times.
Install a New Toilet
We supply and install, or install a fixture you have already bought. We handle standard two-piece models, comfort-height and elongated bowls, and one-piece blind-set units, which take considerably longer to set properly.
Diagnose a Running Toilet
A toilet that refills on its own is leaking past the flapper, and it will do it silently for months. We dye-test to confirm it before replacing anything.
Commercial Toilets and Flushometers
Wall-hung bowls, urinals, and Sloan-style flushometer valves are a different repair with different parts. That work lives on our commercial plumbing page.
Real Toilet Work in Mukilteo
In July 2026 we were called to a house on Marine View Drive in Mukilteo for a toilet that was not flushing properly. Logan Veenstra and Willie Harden rebuilt it — new fill valve, new flapper, new supply line — then flushed it repeatedly to confirm the water level was landing where it should.
The toilet itself was an American Standard two-piece with a tank casting dated September 2006 and a 1.6 gallon-per-flush rating. Twenty years old and completely serviceable: the ceramic was fine, only the parts inside had worn out. The whole visit came to $570.43 including the dispatch fee, against roughly $900 or more to replace a toilet that did not need replacing.
That is the usual outcome. Across our Mukilteo and Everett jobs, rebuilds outnumber replacements: we have logged rebuilds on Marine View Drive and East Oakmont Drive up in Harbour Pointe, wax-seal resets on 53rd Place West after water showed up in a basement, and full replacements on Harbour Pointe Boulevard where the fixture really was finished.

Why we dye-test every toilet we touch
We drop food coloring in the tank and wait. If dye reaches the bowl, the flapper is leaking; if it does not, the seal is good. It takes ten to twenty minutes of sitting still, and it is the only way to prove a running toilet is actually fixed.
A leaking flapper is the most expensive plumbing fault nobody notices, because it makes no sound and leaves no mark — it just shows up on the water bill, often months later. That is why, when a toilet is on the suspect list, we dye-test every toilet in the house rather than only the one you called about.
Rebuild or Replace
Rebuild when the ceramic is sound
If the bowl and tank are not cracked, the toilet is not rocking, and the flush is weak or the fill is slow, the failure is in the parts — and parts are what a rebuild replaces. Age alone is not a reason to replace; the 2006 unit below is proof.
Replace when it is cracked, rocking on a bad flange, or wasting water
A hairline crack in a tank does not get better. Neither does a closet flange that has corroded below floor level. And a pre-1994 toilet at 3.5 gallons per flush is spending your money every time somebody uses it — a modern 1.28 gpf model cuts that by nearly two-thirds.
Replace when you are already renovating
If the floor is coming up or the bathroom is being redone, replacing the toilet while the flange is exposed is cheaper than doing it as its own visit later.
How We Handle Toilet Work
1. Confirm What Is Actually Wrong
Weak flush, slow fill, running, rocking, and leaking are five different faults with five different fixes. We watch it operate before we open anything.
2. Repair, Then Prove It
Rebuild or reset, then flush it enough times to confirm the water level and the flush volume are right. Then dye-test and wait.
3. Check the Pressure While We Are There
Fill valves live inside a pressure range. In Mukilteo we have gauged houses from 52 psi up to 95 psi — and at the top of that band, a new fill valve will fail early. The pressure check is free on the call.
4. Leave the Bathroom Clean
Old parts and packaging go with us. This is somebody’s bathroom, not a job site.
Toilet Repair FAQ
Why does my toilet keep running?
Almost always a worn flapper or a fill valve that will not shut off cleanly. Water leaks past the flapper into the bowl, the tank level drops, and the fill valve restarts — over and over, silently. A dye test confirms it in fifteen minutes, and a rebuild fixes it in one visit.
Should I rebuild or replace my toilet?
Rebuild if the ceramic is sound and only the internal parts have worn out — that covers most toilets, including twenty-year-old ones. Replace it if the tank or bowl is cracked, the flange underneath has failed, or it is a pre-1994 3.5-gallon model that is wasting water on every flush.
How much does it cost to rebuild a toilet in Mukilteo?
A standard two-piece rebuild runs about $399 to $427, plus the $89 residential dispatch fee. Pulling and resetting a leaking toilet with a new wax seal is similar, roughly $402 to $430. What moves the price is access and whether the closet flange underneath also needs work.
Why is water leaking around the base of my toilet?
The wax seal between the toilet and the closet flange has failed, usually because the toilet has been rocking. Water escapes with each flush and tracks along the floor or down into the ceiling below. It is a pull-and-reset repair, not a replacement, if the flange is still sound.
My toilet flushes weakly and burps. What is wrong?
Usually the flapper is closing too early, so the tank empties only partly and the flush never builds enough volume to clear the trap. A rebuild with a correctly sized flapper and a properly set water level fixes it. Persistent burping afterwards points at a venting problem instead.
How long does a toilet repair take?
Most rebuilds and wax-seal resets take under two hours including testing — the Marine View Drive rebuild below was completed inside thirty minutes of arrival. A new toilet install takes longer, and a one-piece blind-set model longer still because of how it has to be positioned and sealed.
