Most toilet repair and installation in Houston comes down to three things: a tank that will not stop filling, water at the base, or a bowl that clogs too often. The first is often a small part. The second needs the toilet lifted. The third decides whether a toilet is worth keeping, and we will say which case you have.
What makes a toilet run all night?
A tank that keeps filling almost always has a leak past the flapper or a fill valve set too high. The EPA says a worn flapper can cause a toilet to flush on its own or silently leak thousands of gallons a year, and it suggests replacing flappers at least every five years.
Run the EPA's dye test: add a few drops of food coloring to the tank, wait 10 minutes without flushing, and look in the bowl. Color in the bowl means the tank is leaking. Flush right after, so the dye does not stain.

Then match the sound to the part:
- Bowl refills every so often: the flapper or seat is leaking
- Constant trickle into the overflow tube: the water level is set too high
- Hissing that never stops: the fill valve has failed
- Weak flush with a running tank: the chain, the handle or the flush valve
A running toilet is also one of the first things to rule out when a high water bill shows up.

Why is my toilet leaking at the base?
A toilet leaking at the base usually has a failed wax seal, a loose toilet, or a cracked flange. Sweat on the tank in a humid Houston bathroom can look the same, so dry the floor and see where the water returns. Water that appears after a flush points to the seal. Water that appears on a humid day with no flushing is often condensation running down the porcelain.
A seal failure needs attention soon. On slab homes, the drain sits in concrete and the water has nowhere to go but sideways, under tile, baseboards and flooring. A soft floor around the toilet, a dark grout line or a sewage smell all say the leak has been going for a while.

How do clogged toilets get cleared in Houston?
A clogged toilet needs a closet auger when a plunger fails, and a look further down the line when it keeps happening. Do not keep flushing to test it. Close the valve behind the toilet if the bowl is rising.
Where the clog sits changes the fix:
- In the toilet trap: an object, too much paper, or a wipe, cleared with an auger
- In the branch drain: the toilet gurgles when the sink or shower runs
- In the main line: several fixtures back up, so call for drain cleaning
Wipes are a repeat offender here. Houston Public Works says about 70% of sewer overflows in the city come from clogs caused by grease and wipes, and its Protect Our Pipes campaign tells residents not to flush wipes, even ones labeled flushable. Toilet paper is the only paper that belongs in the bowl.
Should you repair the toilet or replace it?
Repair when the bowl and tank are sound and one part failed. Replace when the porcelain is cracked, the parts are gone, or the toilet wastes water. EPA's calculator assumes about 5 gallons a flush for toilets installed before 1980 and about 3.5 for those from 1980 to 1994.
| Situation | Better choice | Reason |
|---|---|---|
| Worn flapper or fill valve | Repair | Inexpensive parts, quick fix |
| Toilet leaking at base, porcelain sound | Reset on a new seal | Toilet is fine, and the seal is not |
| Hairline crack in tank or bowl | Replace | Porcelain cannot be reliably repaired |
| Older toilet, 3.5 gallons or more a flush | Replace | Water savings add up |
| Repeat clogs with a clear drain | Replace | Weak flush design or a blocked trapway |
Toilet replacement now means a much smaller flush. State law, at Section 372.002 of the Health and Safety Code, limits toilets sold on or after January 1, 2014 to an average of 1.28 gallons, and dual-flush models average two reduced flushes and one full flush. Some wall-mounted and bariatric models stay at the older 1.6-gallon limit.

What should a toilet install include?
A good toilet install is mostly about what sits under the bowl. Before the new toilet goes down, the flange, bolts and floor all need checking.
Measure the rough-in before you buy, which is the distance from the wall to the center of the floor bolts. Slab floors do not let a drain move cheaply, so a toilet with the wrong rough-in stays wrong. If a remodel raised the floor with new tile, the flange may now sit too low and need an extender.

A sound repair also needs a sound seat. A wax ring only seals when the flange sits at or just above the finished floor, and the bolts hold the toilet down without being cranked tight. Plastic shims take up any rock before the seal gets a chance to break.
What this work includes:
- Shutting off and draining the old toilet
- Removing and disposing of it, if you ask
- Checking the flange, bolts and floor
- Setting the toilet on a new seal, level and solid
- Connecting the supply line and testing for leaks
A repair visit treats the tank parts, the shut-off valve and the supply line as one system, since a new fill valve on a weeping stop fixes nothing.
How toilet repair and installation in Houston goes, start to finish
The visit follows one order, whether the fix is a flapper or a new toilet:
- Tell us the symptom and the age of the toilet.
- We test the tank, the seal and the flush.
- We explain what failed and whether repair makes sense.
- The quote comes next, clear and upfront.
- We repair or replace, then run several flushes.
- We check around the base and at the valve.
What changes the price of toilet work?
The job size depends on what is underneath, and we quote after seeing it. These change the price the most:
- Repair or replacement: one part, or a full toilet
- Who supplies it: a toilet you bought, or one sourced for the job
- Flange condition: sound, loose, or broken at the slab
- Valve and supply line: reusable, or due for replacement
- Floor damage: dry, or soft from a slow leak
- The toilet itself: seat height, bowl shape, and one-piece or two-piece build
A small part on a sound toilet keeps the bill small. The number moves once the toilet comes up, because that is when a rusted flange ring, a raised tile floor or a soft spot shows itself. On a slab, reaching a broken flange can mean cutting concrete around the drain, and that takes more time than a swap. Any flooring repair is separate work.
Does a toilet swap need a permit in Houston?
Usually not, though confirm for your job. The Houston Permitting Center's plumbing fixture page lists toilets among its exempt fixtures, and Section 104.2 of the City's amended code exempts clearing a stoppage, including pulling and resetting a toilet. A defective drain pipe that has to be replaced counts as new work, so moving or rebuilding the drain is a different conversation. An older City repair guideline reads more strictly, which is one more reason to ask. Other cities keep their own lists, so check with the local permit office.
Every Texas plumbing license traces to one office, the Texas State Board of Plumbing Examiners. The Houston Permitting Center can tell you when a fixture change needs a permit.

Toilet Repair and Installation questions
Why does my toilet keep running after I replaced the flapper?
The flapper may not be the failed part. Check the water level first: if it sits above the overflow tube, the fill valve needs adjusting or replacing. Also check the chain, because a short chain holds the flapper open. A flapper in the wrong size for the flush valve opening will never seal.
Is a rocking toilet a real problem?
Yes, because movement breaks the wax seal. Sewer gas and water can then escape under the toilet, and on a slab floor that water spreads under tile or wood before it shows. Do not just tighten the bolts, since that can crack the porcelain. Lift it, reseal it, and shim it level.
How long does a toilet install take?
A straight swap is usually a short visit, as long as the flange and shut-off valve are sound. Time grows when the flange is broken, the floor around it is soft, or the new tank needs a different supply line. Ask to have the old valve replaced at the same time.
Do low-flow toilets clog more than old ones?
No, not current models. Early low-flow toilets had that reputation, and today's designs are tested for flush performance. EPA says WaterSense models use 1.28 gallons or less while performing as well or better. If a modern toilet clogs repeatedly, check for wipes, a partial blockage in the trapway, or a drain line problem further down.
Why does my bathroom smell like sewage with no visible leak?
Look at the toilet seal first, particularly if the toilet moves at all. A dry trap in a little-used shower or floor drain is another common cause, and pouring water in fixes it. If the smell stays, the vent or drain line needs a look, and that may call for a sewer camera.
Toilet running, rocking or leaking at the base? Call before the floor pays for it.
