Most water heater problems trace back to a small number of specific components: a thermocouple or gas valve on gas units, a heating element or thermostat on electric units, or sediment buildup on either. We diagnose the actual failed part before quoting a repair, rather than guessing or defaulting to a full replacement.
This general repair page covers the most common symptoms we see across both gas and electric units. If you already know your unit's fuel type and want detail specific to it, see our dedicated gas water heater repair or electric water heater repair pages.
Most repair parts — thermocouples, elements, thermostats, relief valves — are carried on our trucks, so the majority of repair calls are completed in a single visit.
Common repair symptoms
- No hot water at all, or water that never gets past lukewarm
- Hot water that runs out much faster than it used to
- Rumbling, popping, or ticking noises from the tank
- Pilot light that won't stay lit (gas units)
- Water heater tripping the breaker repeatedly (electric units)
- Rusty, discolored, or metallic-smelling hot water
OUR REPAIR PROCESS
What happens during this service
Phone diagnosis
Describe the symptom and we'll give you a likely cause and rough cost range before dispatching a truck.
On-site testing
A technician tests the specific suspected component — thermocouple, element, thermostat, gas valve — rather than swapping parts by guesswork.
Flat-rate quote
You get a firm price for the repair before any work begins.
Repair & test cycle
Most repairs are completed same-visit; we run a full heat cycle afterward to confirm the fix holds.
PRICING
What affects repair cost
We quote a flat rate on-site before starting any work. These are the main factors that move price up or down for this service in Sherrelwood:
- Which component has failed (thermocouples and elements are lower-cost than gas valves or control boards)
- Unit age and whether parts are still readily available
- Whether the repair is isolated or points to a larger issue (e.g., tank corrosion)
- Access to the unit within your home
FAQ
Common questions about this service
Can you fix it the same day I call?
In most cases yes — common parts are carried on the truck, and a same-day appointment is available for the large majority of repair calls placed during business hours.
Is it worth repairing an older unit?
For a single-component failure on a unit under 8-10 years old, yes. Past that age, or with multiple recent repairs, replacement is often the better value — see our guide on signs you need replacement.
Why does my water heater smell like rotten eggs?
That's usually a reaction between the sacrificial anode rod and sulfur bacteria in the water, not a gas leak. It's a simple anode rod issue we can resolve during a maintenance visit.
Do you charge a dispatch or trip fee?
No separate dispatch fee for calls within our standard Sherrelwood-area service radius — you're only quoted for the diagnosis and repair itself.
