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 Sullivan technicians diagnose both tank and tankless systems on the first visit.
Whatever brand or configuration you have, our Sullivan, WI team has likely serviced it before.
A total loss of hot water gets priority routing since it affects daily life immediately.
We quote the visit and the probable repair range upfront, then confirm the exact price after diagnosis.
If a repair doesn't make financial sense on an aging unit, we'll say so and give you real numbers on replacement instead of patching something near the end of its life.
From a simple pilot light relight to a full heating element replacement, our technicians carry the parts most repairs need on the truck.
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.
We isolate the source of a water heater leak first, since it's not always the tank itself failing.
A total loss of hot water gets same-day priority dispatch, especially in colder months.
A quick call gets a technician scheduled, usually same-day for a total loss of hot water.
Our technician arrives with common repair parts for both tank and tankless systems already on the truck.
The unit is diagnosed, and you'll get a clear repair price — or an honest replacement recommendation if the unit's beyond economical repair.
Once hot water is restored and tested, you get a warranty on both the part and the labor.

We serve Sullivan proper and nearby Sullivan, WI communities on both tank and tankless systems.
As a general guide, a unit past 10-12 years with a major component failure often makes more sense to replace.
We service gas, electric, tank, and tankless systems across Sullivan, WI.
Rumbling is a common early warning sign of sediment buildup, worth addressing before it worsens.
Most single-component repairs, like a thermocouple or heating element, are completed in under two hours.
Tankless systems need different maintenance than tank units, and our technicians are trained specifically for that.
Not always — sometimes it's a fitting or the T&P valve, not the tank itself, and those are repairable.
