Warning signs on a gas water heater

  • Rotten-egg smell near the heater — leave the house and call the gas utility first
  • Water pooling around the base of the tank (tank leaks cannot be repaired)
  • Rusty or discolored hot water
  • Popping or rumbling sounds — sediment built up on the bottom
  • Pilot light won't stay lit, or the burner won't fire
  • Hot water runs out much faster than it used to

What we repair vs. when we replace

Thermocouples, flame sensors, gas control valves, igniters, and drain valves are all repairable parts. A leaking tank is not — once the steel tank corrodes through, replacement is the only safe option.

If your heater is more than 10 years old and needs a major part like a gas valve, we'll give you both prices side by side so you can decide. No pressure either way.

White Oak homes: what we see

Mid-century White Oak homes frequently still have the original galvanized pipe near the heater. We look at the connections and replace short sections with copper or PEX when needed so the new heater isn't bolted to a problem.

Most White Oak homes are on WSSC Water, which licenses plumbers in its service area and runs the cross-connection (backflow) program. Mineral buildup still happens over time, which is why flushing tanks and descaling tankless units pays off.

Sizing and efficiency

Most homes use a 40- or 50-gallon tank. A family of four with multiple showers in the morning usually needs a 50. We look at first-hour rating, not just gallons, to make sure you don't run out. If you're considering tankless, we'll price that option too.

Permits and code for White Oak installs

Water heater replacement requires a permit and proper venting, a thermal expansion tank where required, and a correctly piped temperature & pressure relief valve. We handle the permit and make sure the install passes inspection — shortcuts here are a safety issue, not a style choice.

Before you call

Check that the gas valve is on and the pilot is lit (follow the lighting label on the tank). If you see water at the base, shut off the cold-water supply valve at the top of the heater and turn the gas control to 'Pilot' or 'Off.' If you smell gas, leave the house and call your gas company from outside.

Frequently asked questions

Can you replace my water heater the same day in White Oak?

Most standard 40- and 50-gallon gas heaters, yes — subject to stock and scheduling. Call or text early in the day.

How long do gas water heaters last in White Oak?

Typically 8–12 years. Annual flushing can extend that; sediment and hard water shorten it.

Can a leaking water heater be repaired?

If the leak is from a fitting, drain valve, or relief valve, yes. If the tank itself is leaking, it must be replaced.

Do I need a permit to replace a water heater?

Yes. We pull it and schedule the inspection as part of the job.
