Tap the closest match for a quick plain-English read and your next step. It is a guide, not a diagnosis.
Common Toilet Problems
Constant running, weak flushes, leaks at the base, wobbling and noisy refilling are the most common. Most are inexpensive mechanical repairs.
Running Toilet Repair
A running toilet wastes water and raises your bill. We replace the flapper, fill valve or flush valve and adjust the water level.
Leaking Toilets and Wax Ring Replacement
A leaking base means the wax ring or flange seal failed. We pull the toilet, replace the seal, check the flange and the floor, and reset it.
Toilet Tank and Flush Valve Repairs
Cracked tanks, worn gaskets and stuck flush valves cause leaks and weak flushes. We repair or replace the tank parts.
Toilet Flange and Water Supply Repairs
A broken flange or leaking supply line can cause hidden damage. We repair the flange and replace corroded supply lines and stop valves.
Toilet Installation and Replacement
If the toilet is cracked or old, replacement may be best. We install the toilet you choose with a new wax ring and supply line, then test.

Toilet Repair & Installation FAQs
Why does my toilet keep running?
A worn flapper, a faulty fill valve or a misadjusted float lets water keep flowing into the bowl. Replacing the worn part typically stops it.
Why is water leaking around the toilet base?
The wax ring seal has likely failed, or bolts are loose or the flange is damaged. Stop using the toilet and call us before it damages the floor.
When should a toilet be replaced?
Replace when the porcelain is cracked, the toilet is very old and inefficient, or repair costs approach replacement. Otherwise repair is usually cheaper.
Can you also clear a clogged toilet?
Yes. See our Toilet Clog Removal page for obstructions.
