Toilet repair in Newmarket.

Running toilets, leaks at the base, weak or clogged flushes, a tank that will not fill. Repaired by licensed plumbers with upfront pricing, and an honest word on when a replacement makes more sense.

Can a running or leaking toilet be repaired?

Usually, yes. A running toilet is normally a worn flapper, fill valve or flush seal, and a leak at the base is a failed wax seal or flange. We repair the part, test the flush and tell you honestly if a replacement makes more sense.

A toilet that keeps running wastes water every hour; one that leaks at the base is quietly soaking the subfloor. Seal Plumbing handles all of it for Newmarket homes: flapper and fill valve repairs, flush valve seals, wax seal and flange repairs, supply line and shut-off replacement, and clearing clogs that a plunger cannot. Pete and Joseph are the same licensed plumbers who build our custom bathrooms, and a toilet repair gets the same clean work and leak test.

We also tell you honestly when a repair is not worth it. A 30-year-old toilet with a cracked tank or a worn-out flush valve body is often cheaper to replace than to keep fixing, and a new one uses a fraction of the water. You get both prices and you decide. See our Newmarket toilet installation page for what a replacement involves.

If the toilet rocks or there is water around the base, do not keep using it. The wax seal has likely failed and every flush reaches the floor. Our running toilet guide covers the most common causes.

Toilet Repair questions Newmarket homeowners ask

Usually, yes. A running toilet is normally a worn flapper, a fill valve set wrong or a failing flush valve seal. We replace the part and check the rest of the tank.
It can be. A failed wax seal lets waste water reach the subfloor every flush. We pull the toilet, inspect the flange, replace the seal and reset it. If the flange is broken, we repair that too.
Often mineral build-up in the rim jets, a low tank level, or a partial clog in the trap or drain. We check each and fix the actual cause.
If the toilet is old, cracked, or needs a flush valve body, replacement usually wins on cost and water use. We give you both prices.
Same-day quotes on most small jobs, and we try our best to provide immediate service for leaks.
