Emergency Faucet Repair in Hazelwood, MO

A faucet that will not shut off keeps running into the sink, the floor or the cabinet below until you stop the supply. Our 24/7 line is staffed, and a licensed plumber can tell you which valve to close while we set up the visit.

When a faucet is an emergency

A drip is a nuisance. A valve that will not shut off, a handle that came off in your hand with water running, or a supply line spraying under the sink is an emergency. Look under the sink for two small stop valves and turn each clockwise to close it.

If a stop valve spins freely or will not move, go straight to the main water valve and shut it. Then open the lowest faucet in the house to drain the line. Call us at any hour and a plumber will schedule the repair, with same-day appointments when available.

  • Water running from a faucet that will not close.
  • A supply line spraying or dripping under the sink.
  • A stop valve that will not turn or leaks around the stem.
  • Water pooling in the cabinet with no visible source.

Why faucets leak

Faucets leak because a moving part wears out. Which part depends on the faucet design, and knowing the type tells you whether the fix is a small part or a new faucet.

Sink repairs under the cabinet

Plenty of sink water problems start below the counter. A P-trap with a loose slip nut drips only when the sink drains. A cracked supply line leaks all the time. Dry the pipes with a towel and watch where the first bead of water forms.

  • Loose or worn slip nuts and trap washers.
  • Supply lines that are cracked, kinked or corroded at the nut.
  • Stop valves that seize or weep at the stem.
  • Sprayer hoses and diverters that leak behind the sink.
  • Slow drains, which we clear as drain cleaning work.

Repair it or replace the faucet

A new cartridge or washer is often all it takes. Replace the faucet when the body is pitted or corroded, the finish is flaking, parts for that model are no longer sold, or you have repaired the same faucet more than once.

If you want a different faucet, bring us the model or tell us the hole count in the sink. A three-hole sink will not take a single-hole faucet without a cover plate, and the wrong spout reach splashes outside the basin.

What a repair visit looks like

  1. Shut off the water. We close the stop valves and confirm the faucet is dead before taking it apart.
  2. Find the failed part. We pull the handle and cartridge or washer and check the seat for scoring.
  3. Replace and reassemble. We use the matching part for your faucet, not a close fit.
  4. Test every connection. Hot, cold, the aerator, the supply lines and the trap are checked for drips.

If a stop valve is too corroded to close, we replace it first. Otherwise the next repair means shutting off your whole house.

What drives faucet and sink repair prices

We do not list dollar figures for faucet work, because a dripping washer and a corroded wall-mount valve are very different jobs. What matters is shown below, and we give a clear price before work starts.

The faucet itselfBrand, finish and whether parts are still sold decide whether repair is worth it.
Stop valvesOld valves that seize often need replacing before the faucet can be repaired.
Type of fixturePull-down kitchen faucets and wall-mounted tub valves take more time than a basic bathroom faucet.
AccessA tight vanity or a faucet set into stone takes longer to reach.
After hoursNight and weekend visits can carry a call-out fee, which we state up front.

If water ran into a cabinet or floor for a while, photograph the damage and ask your insurer about coverage before you replace the cabinet base.

Local note

Hard water, chloramines and a 2 degree winter

Missouri American Water reported hardness at its Missouri River plants of roughly 5 to 13 grains per gallon in 2023, which is moderately hard to very hard. The report does not say which street gets which plant, so test your own tap. Minerals clog aerators, scale shower heads and wear cartridges. Unscrew the aerator and soak it in vinegar once or twice a year, and if scale returns within months, look at water softener and filtration.

The utility also uses chloramines, which age rubber washers and O-rings faster than plain chlorine. The City of Hazelwood publishes a winter design temperature of 2 degrees F and a frost depth of 30 inches. Outdoor faucets need the hose disconnected before the first hard freeze, and a frost-free hose bib is a better choice than a standard one. If a hose bib drips inside the wall in winter, call before it freezes.

Faucets are made to ASME A112.18.1, and lead content in faucets and fittings is covered by NSF/ANSI 372. When you buy a replacement, look for those marks on the box instead of relying on the finish and price.

When the leak is not at the faucet

If cabinet water shows up with no drip from the faucet or trap, the source may be a hidden line. See leak detection for how we find it. We take faucet calls from Hazelwood and nearby towns such as Bridgeton.

Frequently asked questions

Yes. The line is open 24 hours a day, seven days a week. Close the stop valves under the sink if you can, call, and we will schedule the visit with same-day appointments when available.

Turn the two stop valves under the sink clockwise. If they will not close, shut the main water valve and open the lowest faucet in the house to drain the line.

Tightening usually squeezes a worn washer or cartridge that has already failed. The drip returns because the part, or the seat behind it, needs replacing.

Missouri American Water's 2023 report shows moderately hard to very hard water at its Missouri River plants. Scale builds up in aerators and cartridges, so clean the aerator regularly and test your own tap.
