Toilet Repair in San Antonio — Fast, Honest Fixes
A toilet that runs all night, rocks on its base, or refuses to flush is not a project to live with. We fix it fast — usually in one visit — anywhere in the NE San Antonio metro.
Toilet calls are the bread and butter of plumbing in this metro, and hard water is the reason. At 14–15+ grains per gallon, San Antonio water scales up fill valves and flappers years ahead of schedule — which is why so many local homes have a toilet quietly running between flushes. A running toilet can waste 200+ gallons a day, and on SAWS or Green Valley water rates that shows up on the bill fast. Hill Country Plumbing Pros repairs running toilets, phantom flushes, weak flushes, stubborn clogs, and leaks at the base across Schertz, Cibolo, Universal City, Converse, and the rest of the northeast suburbs.
We also tell you straight when repair is the wrong call. If a builder-grade toilet from the 1990s needs its third rebuild, or the porcelain itself is cracked, toilet installation often beats another round of parts — and a new comfort-height or dual-flush model pays part of its own way in water savings. Either direction, the tech quotes both options on site so you decide with real numbers, not pressure.

How It Works
- Tell us the symptomRunning, clogged, leaking, or rocking — a quick description over the phone lets dispatch send the right parts on the first trip.
- Diagnose the real causeThe tech inspects tank internals, the flange, and the shutoff valve, then quotes the fix up front before touching a wrench.
- Fix or replace, your callRepairs happen on the spot from stocked parts. If replacement makes more sense, we price it side by side and can usually install the same day.
- Prove it worksWe run multiple flush tests, dye-test the flapper for silent leaks, and check the base and supply line dry before we leave.
What It Costs
Simple toilet repairs in the San Antonio area — a fill valve, flapper, or supply line — generally run $125 to $275. Wax ring and flange work sits around $200 to $450 depending on flange condition, and clog clearing ranges from $150 for a straightforward auger job to $350+ when the blockage is deep in the drain line.
A full toilet installation, including a quality comfort-height unit, haul-away, and new wax ring and supply line, typically lands between $400 and $800 in 2026 pricing. Premium dual-flush or wall-hung models run higher. If your existing toilet needs more than about half the cost of a new one in parts and labor, we will say so.

What moves the price
- What failed — flapper and fill valve vs. flange and wax ring
- Clog depth: bowl-level vs. down the drain line
- Flange condition — corroded or broken flanges add repair work
- Repair vs. full replacement with a new fixture
Toilet Repair FAQs
Why does my toilet keep running?
Nine times out of ten it is a flapper or fill valve worn out early by our hard water — mineral scale keeps the flapper from sealing, so the tank refills all day. It is a fast, inexpensive fix, and worth doing quickly: a running toilet can waste over 200 gallons a day.
My toilet rocks a little. Is that a big deal?
Yes, more than it seems. Rocking usually means the wax ring seal is broken or the closet flange is damaged, and every flush can seep water under the toilet into the subfloor and slab area unseen. Fixing it early is a modest repair; ignoring it can mean rotted flooring.
Can you get a badly clogged toilet cleared today?
Almost always. Clogged toilet calls are prioritized because most homes cannot go long without one, and we serve the whole NE metro from Universal City up to New Braunfels. If the auger shows the blockage is actually in the drain line, we handle that on the same visit.
When should I replace instead of repair?
Cracked porcelain is automatic — no repair holds. Beyond that, if a pre-1994 3.5-gallon toilet needs its second or third rebuild, replacement usually wins: a modern dual-flush unit uses less than half the water and comes with all-new internals under warranty.
Do you install toilets the customer buys themselves?
We do. Buy the model you like and we handle the install — new wax ring, bolts, supply line, and leveling included. We will also flag it before installing if the bowl you bought will not fit your rough-in measurement, which saves a return trip.
