Water Heater Services in Greater San Diego

30 Years of Experience with Installation & Repair

A reliable hot water supply is essential for daily activities like showering, cleaning, and running appliances. If you’re experiencing a sudden loss of hot water or you’re worried about your water heating unit, CastleWorks provides prompt solutions and premium products for residents of San Diego. Our carefully trained water heater plumbers can repair all the major types of heaters including gas, electric, tankless, and heat pump water heaters.

Here are some reasons why CastleWorks is a popular choice in the San Diego region:

Our brand focuses exclusively on repairing and installing water heaters.
We only install premium-quality water heater products with excellent optional warranties.
We offer maintenance plans with locked-in pricing.
Brand new water heaters can be installed within a 3 hour turnaround time.
Our Bradford White water heaters are made in the USA.
No-money-down financing options are available.

Finding a plumber you can trust with water heater problems can be tough. The urgency involved can make things even more stressful. At CastleWorks, we don’t believe in cutting corners on quality. We pull permits on every water heater install, and we specialize in same-day resolution for installations and for many of our repairs as well.

Same-Day Water Heater Installation in San Diego

Our ability to provide same-day service is something that we have become well-known for. Unlike other companies, we carry new water heaters with us everyday, 7 days a week. That means we can do almost all replacements the same day you call. While many plumbing businesses complete a new water heater install maybe once a week, our team is regularly installing 2 new water heaters a day. This allows us to bring a level of experience that is hard to find anywhere else, even in a highly populated area like San Diego.

 Trustindex verifies that the original source of the review is Google. This is our second huge projects with Castleworks. Justin went above & beyond, not only making what could have been  a huge issue. He figured out the best way to do do with a very minimal amount of holes in walls. He did the work quickly & despite the very small holes needed to connect the pipes, he made it all look like a work of art. I highly recommend recommend the company for any plumbing needs & a special shout out to Justin

 Trustindex verifies that the original source of the review is Google. I would rate my experience with Christopher Beauvoir's installation of a new water heater as a "5".   He was extremely professional and straight-forward about the entire process.  Explained teh issues with my old water heater, and installed the new one quickly and efficiently.  I would not hesitate to recommend Castle Works to my associates if and when they need that kind of service.  thanks again for solving my hot water issues!

 Trustindex verifies that the original source of the review is Google. CastleWorks does excellent work.  Christopher Beauvoir showed up on time, was very knowledgeable, and did an excellent job replacing our old water heater in the garage.  They use Bradford White water heaters which are really good.  Very happy with the job, thank you!

 Trustindex verifies that the original source of the review is Google. CastleWorks’ technician, Christopher Beauvoir, showed up on time and quickly diagnosed the problem with the Grundfos circulation pump on our tankless water heater. He also discovered several faulty valves that had deteriorated over the years. Christopher replaced the failing pump and valves and was on his way in short order.

 Trustindex verifies that the original source of the review is Google. We needed to replace our large 100 gal water heater (4.5 Ba house) and called Castleeworks when some slight leakage was visible in the drain pan.  Great same-day service by Salvador Vidales, who provided the price estimate, consulted with us on options, and got us an additional discount because we were replacing with the exact same brand that they usually install, so no new major piping was rquired other than the usual new connectors. Waived the delivery fee for the new unit which was in Pomona several hours away on high traffic congestion day.. Salvador was also the installer, very capable and workmanlike.  Had the whole worksite set up and old unit ready for removal when the delivery/installation guys arrived on the hottest day of the year. When the new alumuinum drain pan got dented in the installation on our raised pad which didn't look good, he pro-actively had the team pull the new unit back off and installed another replacement drain pan to make sure we were happy with the results.  After the delivery guys left when the unit was in place, he worked for several more hours finishing at 7 pm.  Showed good workmanship, gave us good advice.  We were very happy with Salvador and the company so far at this point.  Obviously the proof of the pudding will be in the new unit and our service contracts and warranties, but we're off to a very good start and would highly recommend based on this experience on Day One!

 Trustindex verifies that the original source of the review is Google. I am more than satisfied with the service I received from Castleworks Home Services.  From taking my phone call after hours when I discovered that my water heater was broken and leaking, and scheduling an appointment for the very next day… to keeping me updated on the estimated arrival time of my technician including a text with his full name and photo ID was truly impressive.  But what was even more impressive is the actual service itself.  Justin, the technician, was extremely easy to work with.  He was knowledgeable, polite, explained everything, answered all of my questions, and completed all of the work in one visit.  I couldn’t ask for a better experience and highly recommend this company! 5 ⭐️⭐️⭐️⭐️⭐️
