Orange County Water Heater Professionals 

Same-Day Turnaround for New Installations

Is your water running cold from the tap? Have you noticed water pooling around your unit? Are there popping noises inside your tank? Quickly diagnosing problems like these is what our team at CastleWorks focuses their attention on 7 days a week. We are water heater specialists who focus exclusively on water heating systems and whole home water purification. Unlike the average plumbing company, stretched thin across a number of specializations, our business has been refining repair and installation processes on water heaters alone over the past 30 years.

Why choose CastleWorks to fix your water heater problem?

  • We have seasoned techs with an average of 7+ years of experience. 
  • We use the only water heater still made in the USA (Bradford White).
  • We never cut corners on quality. 
  • Our team is highly-rated for friendliness, speed, and attention-to-detail. 
  • We offer 4 unique install packages with price points based around your needs.

From the first call to the final interaction, you can expect to have all your questions answered carefully by members of our team. We understand that a water heater is an important investment, and we want to make sure you spend your money on a solution that lasts.

Water Heater Repairs That Keep Your Unit Running

If your unit is less than 8 years old, there’s a good chance it still has a few years of operation left. However, if your unit has passed the 8 year mark and is nearing or exceeding the 10 year mark, a new system may be the more cost-effective choice. If repairing turns out to be the best option for you, we keep our vans fully stocked for every situation. That means we are able to complete many repairs on our first visit. If you want to stay proactive and prevent further unexpected breakdowns, we also offer maintenance plans that unlock free evaluation, testing, and discounts on future services.

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!

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 ⭐️⭐️⭐️⭐️⭐️

We have just had 2 excellent experiences with Castleworks. Picked up the phone right away and was great with communication via phone and text to keep us informed as to when our technician would be out. And Justin the technician himself was absolutely amazing. Knowledgeable, worked clean and quick. We had such a good experience we ended up calling them back out right away for another issue with A/C that was long overdue and had another great experience with Brendan. So hard to find reputable companies that do what they say and that you can trust. Fully recommend them. Save their number!

James Skresvig went above and beyond for me. He even changed a hose for me, completely unrelated to the job he came to do, just to help me out because I didn't have the right tool. He answered all of my questions and was very good at explaining their services without overselling anything - more like explaining options.

Besides getting our water heater running, James was very knowledgeable and gave me useful information about upgrading to tankless. Would definitely use again!

Water Heater Replacement in Orange County

 If you’re wondering if it’s time to buy a new water heater, our professional technicians can advise you on what signs to watch for with your unit. Usually, the telltale signs are obvious, and we don’t push for replacement unless you are as ready to change out your unit as we are. If you’re curious, we’ve broken down some of the most common signs to watch for below.

Here are a few signs that it may be time to install a new system:

  • Your unit is 10-12 years old or older.
  • You see water pooling due to a leak on the bottom of the tank. 
  • You have rusty-looking water.
  • Rust is spreading on the outside of your tank. 
  • You’ve had to repair your unit recently already.

Pooling water doesn’t always mean there’s a fatal problem. Leaks can just as often be due to faults with valves or pipes. But you definitely want to have a water heater expert visit over the short term if you notice a leak because a tank with structural integrity problems can explode and cause extensive water damage.
