Questions

Frequently asked questions

How do I know if I need a new water heater or just a repair?

Not every water-heater problem requires replacement. We check the age, condition and failure point, then explain whether repair or replacement makes better sense.

Why is my water heater leaking?

Leaks can come from valves, fittings, connections or the tank itself. We locate the source and explain the repair options before work begins.

Will you tell me what’s wrong before doing major work?

Yes. Our process is diagnosis first: we show you what we found, explain the options and let you decide how to move forward.
