Toilet Repair & Installation in Denton, TX
A toilet that runs all night, rocks when you sit, leaks at the base or clogs every week. Toilet repair and installation in Denton, TX covers the tank parts, the seal to the floor and full replacement, and an overflowing toilet that will not stop can be handled 24/7.
What the symptom usually means
Toilet repair covers the parts in the tank, the seal at the floor and the bowl itself. Most problems point to a specific part.
| Symptom | Likely cause | Typical fix |
|---|---|---|
| Runs or hisses between flushes. | Worn flapper or failing fill valve. | Replace the flapper or fill valve. |
| Water on the floor around the base. | Failed wax ring or loose flange bolts. | Pull the toilet and reset with a new seal. |
| Toilet rocks. | Loose bolts or a broken flange. | Repair or replace the flange, then reset. |
| Weak flush. | Mineral buildup in the rim holes and jet. | Clean the jets, or replace an old toilet. |
| Clogs often. | Low-flow bowl design, or a line problem. | Test the bowl, then check the drain line. |
| Crack in the tank or bowl. | Porcelain failure. | Replace the toilet. |
If several fixtures are slow too, see our drain cleaning page, since the clog is likely further down the line.
Why running toilets matter on a Denton water bill
A running toilet is the single most common cause of a high water bill with no visible leak. A worn flapper can let water trickle into the bowl for weeks, and the only sign is the next City of Denton bill.
The dye test finds it. Add a few drops of food coloring to the tank, wait 15 minutes without flushing, and look in the bowl. Color means the flapper is leaking.
Mineral-heavy water shortens the life of tank parts here. Scale stiffens flappers and gums up fill valves. On older toilets, it also clogs the small rim holes that make a flush strong. If your bill is still high after the toilets pass, leak detection is the next step.
What a toilet visit includes
Most toilet jobs are same-day work. A typical visit covers:
- Tank rebuild: flapper, fill valve, flush valve and supply line as needed.
- Reset: pulling the toilet, inspecting the flange and setting a new wax or foam seal.
- Flange repair: fixing a broken or corroded flange so the toilet sits firm.
- Full replacement: removing the old toilet and installing a new one, including a new supply line and shutoff if needed.
- Clog clearing: auger work on the bowl and trap.
Choosing a new toilet
New toilets sold in the US are built to use far less water per flush than older models, and many meet the EPA WaterSense standard of 1.28 gallons per flush or less. On an older 3.5-gallon toilet, the savings show up quickly.
The measurement that matters most is the rough-in: the distance from the finished wall to the center of the floor drain. Most homes have a 12-inch rough-in, but some older homes differ. Buying the wrong one means it will not fit.
Comfort-height bowls sit a couple of inches taller and are easier for many adults, including residents of 55-plus communities like Robson Ranch. Elongated bowls take more room than round ones in a small bathroom.
What toilet repair and installation cost depend on
These are the main variables.
- The part. A flapper costs very little. A flange repair costs more.
- Whether the toilet has to be pulled.
- Floor condition around the flange, especially if a slow leak softened the subfloor.
- New toilet model, whether supplied by you or by the plumber.
If a leaking wax ring damaged the floor, insurance may cover it only if the leak was sudden. Slow leaks are usually excluded.
Toilet questions
If the porcelain is sound and parts are available, a tank rebuild is cheap. If the toilet is old, uses a lot of water per flush and clogs often, replacing it usually pays off.
Turn the small valve behind the toilet clockwise. If it will not turn, lift the tank lid and push the flapper down, then close the main if needed.
