 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!
