Water heater service in Oceanside
Oceanside is home base. Our shop is on Oceanside Blvd, so we're usually the quickest water heater service you can get anywhere from South O up to Morro Hills. When a tank fails in the morning, same-day replacement here is routine.
A lot of Oceanside homes were built in the 1970s and 80s, and many still have tank heaters tucked into garages or exterior closets. Those older installs often need code updates when the tank is replaced, like double seismic straps, a properly piped relief valve, and an expansion tank. We include those in the written estimate so there are no surprises.
Closer to the coast, salt air wears on vent caps, gas connectors and fittings faster than it does inland. When we service a heater west of I-5, we check those parts every time.
What customers say
Reviews from North County homeowners, as posted on Yelp.
Becky P.
Oceanside, CA
"I had a 21-year-old water heater that was on its last legs. I called and got a quote, liked the price, and booked the appointment. They showed up on time, put a new water heater in, didn't leave a mess, and stuck to the price they quoted. The next day I had a little issue and they came right out and fixed it. It's been perfect ever since."

"If you're looking for an honest plumber who is responsive, helpful and professional, then call Mike Welch. He showed up on time, explained everything clearly, and the price was exactly what he quoted. Couldn't be happier with the service."

"Mike, Chaz and Eric are friendly, nice, efficient, and professional! They installed our new tankless water heater quickly and cleanly. The whole team was a pleasure to work with. Highly recommend Welch's for anyone in the area."

"The owner has assisted us many times with a variety of major/minor repairs to our old house. He has always come quickly, assessed issues successfully, and is very fair on price. Personable and honest. Can't say enough. 5 Star Service."
