Toilet Leak Detection and Repair in Round Rock, TX
A toilet that leaks at the base is doing quiet damage to the floor under it. The water seeps into the subfloor with every flush, so the small repair today prevents a much larger one later.
Where a toilet leaks
A toilet has a handful of leak points, and they show up differently. Water pooling at the base after a flush usually means the wax ring has failed or the flange beneath it has cracked. A puddle at the back points to the supply line or the shutoff valve. A constant trickle inside the bowl is the flapper or the fill valve wasting water you pay for. Each one tells us where to look.
In older Sendero Springs homes with original flanges set in the slab, the base leak is the one we see most, because the cast or plastic flange has had decades to corrode or crack.
Finding the real source
We do not assume the obvious. A leak that looks like base seepage can actually be condensation off the tank in a humid bathroom, or a supply fitting weeping down the back and pooling in front. We dry everything, run the toilet, and watch where the water truly returns. A dye test in the tank confirms a silent flapper leak that never reaches the floor.
Once we know the point, the fix is targeted. If your toilet rocks or the floor around it feels soft, call (512) 737-6168 and we can check the flange before the subfloor gives.
Wax ring, flange, or supply repair
A failed wax ring is a pull-and-reset: we lift the toilet, replace the seal, and set it true so it stops moving. A cracked flange needs repair or replacement so the toilet has something solid to seal against, and a rotted closet bolt gets renewed at the same time. A weeping supply line or shutoff valve is a straightforward swap. We fix the actual failure rather than caulking around the base to hide it, which only traps the water.
Where the subfloor has already softened, we will tell you plainly and walk through what restoring it takes.
Why hard water shortens toilet parts
Round Rock water runs hard, near 15.2 grains per gallon, and the city treats with chloramine. That combination is rough on the rubber and plastic inside a tank. Flappers stiffen and stop sealing, fill valves crust with scale and stick, and the slow internal leak that follows can run thousands of gallons before anyone notices on the bill.
Swapping those worn parts is cheap next to the water they waste. We check them while we are there, so a base repair does not leave a hidden tank leak behind.
A toilet leak is also one insurance adjusters ask about, since a slow base seep can rot a subfloor for months before it shows. We note what failed and what we replaced, so you have a record if the floor damage turns into a claim. The plumbing fix is quick, and the documentation is what helps later if the subfloor itself needs work.
What to expect when we arrive
We confirm where the water is coming from before pulling anything, so you are not paying for a reset the toilet did not need. You hear the cause and the fix, with the cost up front. With your go-ahead we make the repair, reset the toilet level and solid, and check that the seal holds through several flushes.
We clean up the area before we leave. For a toilet actively leaking onto the floor, that water is reaching the subfloor right now, so call (512) 737-6168 and we can come any hour.

📞 (512) 737-6168Frequently Asked Questions
Why is there water around the base of my toilet?
Usually a failed wax ring or a cracked flange under the toilet. Less often it is condensation or a supply fitting weeping down the back. We confirm which before repairing.
Can I just caulk around the toilet to stop it?
No. Caulk traps the leaking water against the subfloor and hides the damage. The wax ring or flange has to be repaired so the toilet actually seals again.
My toilet runs constantly. Is that a leak?
Yes, an internal one. A worn flapper or fill valve, often stiffened by hard water, lets water trickle from tank to bowl and wastes it. It is a quick, cheap fix.
