Toilets fail in specific, diagnosable ways. The running sound after a flush, the phantom flush that cycles with no one in the bathroom, the wobbly seat, the bowl that won't clear with one flush β each one points to a specific component. Our techs in Mount Airy diagnose the actual cause and fix the specific part that failed.

A rocking toilet that's dismissed as a loose bolt and tightened without replacing the wax ring will continue letting sewer gas into the bathroom floor cavity. The right diagnosis matters.
Phantom flushing (spontaneous refill with no flush) almost always indicates a flapper that no longer seals β a 10-minute repair. But sometimes it's a hairline crack in the overflow tube that keeps the water level from holding. We check both.
For toilets where the flush valve seat is chipped or the porcelain tank has cracked, we also carry compact replacement toilet units in standard rough-in dimensions.
Pulling and resetting a toilet requires shutting the water, draining both tank and bowl, disconnecting the supply line, unbolting the toilet from the flange, removing the old wax ring fully, inspecting the flange for damage, and seating a new ring with the correct compression profile for the floor height before resetting and re-bolting the toilet.
We quote toilet work at a flat rate before any repair begins. Whether it's a 20-minute fill valve swap or a 90-minute toilet reset with flange repair, you know the price before we start. Our rates for common toilet repairs are published β ask for them when you call.
Our trucks are stocked for the most common toilet repairs β most calls complete in a single visit.
A running toilet is almost always caused by one of two things: a flapper that no longer seats fully against the flush valve (allowing water to trickle from tank to bowl), or a fill valve that won't shut off at the target water level. We dye-test to confirm the flapper seal, check fill valve shutoff behavior, and replace whichever component β or both β is responsible.
If the flange is damaged β cracked porcelain collar, corroded cast iron, or a flange sitting below finished floor height β we repair or shim the flange before wax ring installation. A wax ring on a damaged flange won't hold long-term.
If the auger retrieves material and the toilet still doesn't clear, the blockage may be further in the drain line. We can extend the scope with a sectional cable machine or CCTV camera to determine if a foreign object (typically a toy or wipe product) is lodged deeper.
The flush valve is the large central drain at the bottom of the toilet tank. Over time, the flush valve seat β the surface the flapper seals against β can develop mineral scale buildup or micro-fractures that prevent the flapper from sealing completely. If a new flapper doesn't resolve a running toilet, the flush valve seat is the next check.
The bolts and rubber gasket connecting the tank to the bowl can deteriorate over years of service, leading to slow leaks at the tank base or a tank that shifts side to side. We drain and remove the tank, replace the spud washer (tank-to-bowl gasket), install new brass bolts with neoprene washers, and reseat the tank with correct torque to avoid cracking the porcelain.
We handle the full process: shut water, pull old toilet (including wax ring and flange inspection), set the new unit, connect supply, and verify flush performance and seal before leaving.
Here's how a Masters Plumbing Service toilet call plays out in Mount Airy, NC from your first call to a quiet, leak-free bathroom.
We ask whether you have a gravity-feed toilet (standard) or a pressure-assist model, which affects which parts we bring.
For a rocking toilet, we assess floor movement, flange bolt tightness, and wax ring seal before recommending the appropriate repair.
Based on diagnosis, you receive a flat-rate quote before the tech picks up a wrench. Common repairs are priced β fill valve replacement, flapper replacement, wax ring reset, clog clearing β and you see exactly what you're agreeing to.
Approved repairs execute immediately. After completion, we run five flush cycles to confirm the repair holds β silent tank refill, no base movement, clear bowl, no water at the base.

Three toilet repairs in one visit across two bathrooms. The tech moved through each one efficiently β new fill valve in the master, flapper replacement in the hall bath, and a wax ring reset in the kids' bathroom that had been slightly loose for over a year. All flat-rate, finished in two hours.
My kids flushed something that I have no interest in describing, and the toilet wasn't clearing. The tech used a closet auger and retrieved the obstruction without damaging the porcelain. Fast, professional, zero judgment. Exactly what I needed.
Water pooling at the toilet base had me convinced it was the wax ring. Tech traced the water to a corroded tank bolt β water was running down the outside of the bowl and pooling at the base without any leak at the floor seal. A 25-minute repair, not the toilet reset I was dreading.
