Leaking Toilet Repair in St. Louis
Toilet leaks can cause significant water damage to your bathroom floor, subfloor, and even the ceiling below. Leaks can originate from the base of the toilet, the tank, or the supply line. Common culprits include a worn-out wax ring, loose bolts, or cracked porcelain. We thoroughly inspect all potential leak points, replacing seals, tightening connections, or recommending bowl replacement if the porcelain is damaged, preventing further water intrusion.

Weak Flush and Clog Repair in St. Louis, MO
If your toilet needs two flushes or clogs often, the problem may be scale in the rim jets, a partial blockage in the trapway or a flush valve that does not open fully. We auger the trap, check the vent if gurgling is present and clean the jets with a descaling treatment. Some low-flow toilets from the 1990s simply flush poorly, and we will tell you plainly if replacement is the better fix.
Toilet Flush Mechanism Repair in St. Louis, MO
If your toilet isn't flushing properly, it could be due to issues with the flush chain, handle, flapper, or fill valve. A weak flush might mean the tank isn't filling correctly, while a loose handle might not be engaging the flapper. Our plumbers are adept at diagnosing these internal tank problems, replacing worn or broken components like flush valves, fill valves, and toilet handles to restore full and effective flushing power.
Brands We Service in St. Louis, MO
FGV Plumbing is experienced in repairing toilets from all leading manufacturers commonly found in St. Louis, MO homes and businesses. This includes well-known brands like Kohler, American Standard, Toto, Delta, Eljer, and Gerber. Our plumbers are familiar with the specific designs and proprietary parts of these brands, allowing for accurate diagnosis and efficient repair. We stock a wide range of common replacement parts to ensure that most repairs can be completed on the first visit, regardless of your toilet's brand or model.
Fill Valve Replacement in St. Louis
A noisy, slow or hissing tank often points to a worn fill valve. Mineral scale clogs the small ports inside, which causes long refill times and phantom refills in the night. We replace old ballcock valves with modern adjustable fill valves from Fluidmaster or Korky and set the water level to the manufacturer mark. The job takes about 20 minutes and makes an older toilet much quieter.
Leaking Toilet Base Repair in St. Louis, MO
Water around the base typically means the wax ring has failed or the toilet has been rocking on a loose flange. On slab foundations, the flange often sits on concrete and can crack when bolts are overtightened. We pull the toilet, inspect the flange, install a repair ring or new flange if needed and reset the bowl on a fresh seal. We also check for soft flooring so you know if any water damage needs attention.
Leaky Toilet Repair in St. Louis
A leaky toilet can waste hundreds of gallons of water each year, increasing your utility bills and potentially causing water damage. Our technicians in St. Louis are experts at identifying the source of leaks, whether it's a cracked tank or bowl, a faulty wax ring, or a worn-out fill valve. We use specialized dyes and pressure tests to reliably locate hidden leaks and provide durable repairs, often involving the replacement of seals, gaskets, or the entire flushing mechanism. Ignoring a leak can lead to structural damage or mold growth, so prompt repair is crucial.

Pressure-Assist and Dual-Flush Repair in St. Louis
Pressure-assist toilets from Sloan Flushmate and dual-flush models from TOTO and American Standard use parts that hardware stores rarely stock. We carry cartridges, flush buttons and seals for the common models and can order specialty parts fast. These systems need correct pressure settings to work well, so we test incoming water pressure as part of the repair.

Frequently Asked Questions About Toilet Repair in St. Louis
The cost of toilet repair in St. Louis, MO can vary widely depending on the issue. Minor repairs like replacing a flapper might range from $120 to $250, while more complex issues such as main drain clogs or wax ring replacements could be between $200 and $500. We provide a transparent, upfront estimate after diagnosing the problem.
Weak flushing can be caused by several issues, including insufficient water in the tank, a clogged rim jet, a partially closed stop valve, or a partial clog in the drain line. Our plumbers can diagnose the exact cause and restore full flushing power.
A failed wax ring or a loose, cracked flange is the most common cause. Condensation on the tank can also drip down and look like a base leak. We pull the toilet, inspect the flange and reset it on a new seal.
Yes, FGV Plumbing stands behind all our toilet repair work in St. Louis, MO with a comprehensive warranty on parts and labor. We want you to feel confident in the durability and quality of our repairs. Specific warranty details will be explained at the time of service.
While some minor issues like a simple flapper replacement can be a DIY fix, many toilet repairs, especially those involving the internal mechanisms, drain lines, or significant leaks, are best left to professionals. Improper repairs can lead to greater damage, water leaks, or code violations.
Most standard toilet repairs, such as fixing a running toilet or replacing internal tank components, can be completed within 1 to 2 hours. More complex issues like clearing a tough main line clog or replacing a wax ring might take longer, potentially 2 to 4 hours.
Swapping a flapper is a reasonable DIY job if you match the right size and the flush valve seat is smooth. Base leaks, flange repairs and cracked tanks are better left to a plumber because a bad reset can cause hidden water damage to the subfloor.
While some minor running toilet issues, like a simple flapper adjustment, can be DIY, more complex problems may require a professional. If you're unsure about the cause, or if the issue persists after basic troubleshooting, calling FGV Plumbing ensures an accurate diagnosis and lasting repair, avoiding potential water waste or damage.
