Christopher was fantastic! Arrived right on time, friendly, happy in his work. Very informative and taught me a lot about water heaters! Luckily for me, my problem was the pilot light. However, he also checked for gas, leaks and various other possible problems. He informed me of future maintenance and suggested repairs for the future.

Elston Walker was the water heater technician that Castle Works dispatched after regular hours when our 25 year old water heater went out with a splash😩Elston has a brand new up to date technology water heater installed within 2 hours. We caught our flight and now I am posting this from Lisbon Portugal and our daughter has all the hot water she needs!🤣

Salvador was wonderful. He introduced himself at the door and was very courteous while he was here. He did his inspection and gave us a fair quote. He had the necessary parts and was able to complete the repairs.

After 1 appointment cancellation at request of firm, Justin arrived on the next scheduled visit. His service was thorough and well explained. He also decided to not bill extra on an existing condition and he chose not to pursue. Overall very happy with the service and confident in the work performed.

Common Signs That Repair Is Needed

The most obvious sign of a problem is cold water coming out of your faucet or showerhead. But there are other things to watch out for that may indicate a need for repairs. We’ve outlined some of them below.

  • Rusty or Discolored Water: This can be a sign of a few different things. It may mean that you have sediment buildup at the bottom of your tank or that the anode rod is failing. It may also mean that your tank walls have started to rust.
  • You Hear Noises Coming from Your Unit: Sometimes, sediment buildup can cause popping sounds as bubbles form underneath and rise to the surface. Whistling sounds often relate to a valve problem.
  • You See Water Pooling: This can happen if there’s a problem with the pressure relief valve or the drain at the bottom. But it may also indicate a crack in your tank, which would mean it’s time to replace the unit.
  • The Pilot Light Won’t Stay On: This can be caused by problems with the thermocouple, which may be damaged or have too obstructing it. You may also have a problem with the control valve failing to deliver gas correctly
