Frequently Asked Questions — Toilet Repair & Installation in Houston

How much does toilet repair cost?

Most toilet repairs cost $75–$300. Flapper or fill valve replacement runs $75–$150. Wax ring replacement is $90–$200. Toilet installation including removal of the old unit costs $150–$400 for labor, plus the fixture cost ($100–$800 depending on model).

Why is my toilet running constantly?

A constantly running toilet is almost always caused by a faulty flapper (valve at the bottom of the tank) or a worn fill valve. Both are inexpensive parts — under $20 — and a plumber can replace either in 30–60 minutes. A running toilet wastes 200+ gallons per day, adding $70+ monthly to your water bill.

What is a wax ring and when does it need replacing?

The wax ring seals the toilet base to the drain flange. It needs replacement when the toilet rocks, when there is water or odor at the base of the toilet, or when the toilet is being replaced. Wax ring failure leads to sewage leaks under the floor — a health hazard worth addressing immediately.

Can a plumber unclog a toilet?

Yes. A licensed plumber can clear toilet clogs that a plunger cannot shift, including clogs deep in the drain line or caused by objects accidentally flushed. For recurring clogs, a camera inspection can identify whether the problem is in the toilet or further down the sewer line.
