Cold showers, a rumbling tank, a pilot light that won't stay lit, or a tankless unit throwing an error code — a failing water heater rarely fixes itself, and most failures give warning signs first. Our Clayton technicians diagnose both tank and tankless systems on the first visit.
Our Clayton technicians are trained across both fuel types and both system designs, not specialized in just one.
A total loss of hot water gets priority routing since it affects daily life immediately.
You'll know the diagnostic and likely repair cost before we open the access panel.
We won't recommend a costly repair on a unit that's already past its expected service life — you'll get an honest comparison.
These are the water heater problems we diagnose most often across Clayton, MO.
Failed heating elements, faulty thermostats, and leaking T&P valves are diagnosed and repaired on standard tank units.
Tankless systems need descaling and flow sensor cleaning periodically — we service both the repair and that maintenance.
We test the thermocouple and gas valve together, since a weak pilot can point to either component.
Sediment buildup at the tank bottom reduces efficiency and causes rumbling; a flush and inspection often restores performance.
A leaking tank fitting or failed temperature-and-pressure relief valve gets repaired before it becomes a bigger water loss.
We carry common elements, thermocouples, and igniters on the truck specifically for same-visit no-hot-water repairs.
Tell dispatch the brand, fuel type, and symptoms if you know them — it helps route a technician with the right parts.
Our technician arrives with common repair parts for both tank and tankless systems already on the truck.
We explain what's actually failing and give you the real cost comparison before you decide.
Once hot water is restored and tested, you get a warranty on both the part and the labor.
