    Before: Old PRV Valve
    Mark M.

    Found RJB Plumbing on Yelp today, having a 5.0 star rating and 140+ reviews I felt pretty comfortable contacting them. I contacted them through Yelp and got a response within minutes. I needed my Pressure Regulating Valve replaced, they sent a quote and offered to be out in 45 minutes if needed. We agreed on the price and Bob came out and did the work, super nice guy, lives the next neighborhood over! He explained exactly what and how he was going to do the replacement and even got me a double union PRV so that next time I could literally replace it myself in about 30 minutes! (as long as I got the exact same model). He even left the area cleaner than he found it! I won't hesitate to call RJB Plumbing if I have any plumbing needs in the future. 5 Stars all the way!

    Bob saved the day. To start, he talked me through the mistake I made when striking my main water line. Since it was late in the day on the weekend, Bob was able to schedule me the next work day and he fixed the issue. And, he really is a nice guy and knows his stuff! 100% recommended!

    Whole house filtration system installed by Bob.

    Bob takes pride in his work, and it definitely shows. He is detail oriented and has incredible expertise to help. In my case, he was able to re-pipe all the exposed copper pipes in my attic with PEX. He also installed a whole house, water filtration system, and a Moen valve that detects leaks. As you can see, the quality of his work shows with beautiful copper welds, and neat plumbing.

    Nice work by Bob!

    Amazing job and I'm a happy customer! Our water heater broke and first thing I did was to go to yelp to find someone to fix it. We never had plumbing issues until this incident so a plumber is not on our phone books. I saw the reliable reviews from RJB plumbing among others. But what stood out was that Bob was the business owner who directly responded and came out to look at the issue. I'd rather have to deal with one person all the way through than a receptionist who sends a random plumber to my house.The other thing is he's open 24/7 and he said I could call him whenever if there's an emergency! That's really reassuring! Also he's in San Marcos, close to where I live. As for his service, he was patient, knowledgeable and helpful. He responds quickly on Yelp and via text. He came in a very short time to provide us a free estimate and arrived on time the next morning for the heater replacement. He swept the floor, cleaned the area, installed the tank securely, stored away the warranty documents neatly, wore shoe covers in the house - professional! I felt safe to leave him do his own thing, and not having to watch over him. He also charged a very reasonable price. I also wanted to replace the whole shower and arm and he went to Home Depot right away to get it done for me after the heater was finished. We're very very happy with his work and professionalism. Highly recommended!

    Brought my sink/faucet install up to the code...I am super happy and grateful!

    Can I send you a photo?

    Yes

    SDGE said the valve in our patio fire pit is leaking gas. Can you do those repairs?

    Yes we can replace valves or pip but sometimes that would require opening up potentially the wall to get access to it

    We were replacing a broken toilet ourselves, but removed the old one to find that the setting in…read morethe floor was completely borked. There was no actual flange at all, just a repair flange and it was set below the level of the flooring and filled in around with a mess of some kind of caulk or filler to try and raise the level up. Making this right was way out of our league, so we called MasterCraft to help us out. They confirmed our suspicions that this was messed up six ways from Sunday and talked through the process of cleaning out the filler, chipping away the concrete, and refilling it with a clean setting of concrete so they could set a proper flange 1/4" above the flooring and for a reasonable price considering how terrible the setup was. They immediately set up an appointment to return the next day. While they were there for the estimate, they offered a free inspection of the plumbing in the rest of the house, which I took to be a fishing expedition for more "problems" they could "fix" for more money, but such was not the case. They found one minor issue, said it could probably wait a few years, and even fixed another minor issue they found for free, then said everything else looked good. Startling honesty and helpfulness! From my call for help, they had folks out to check things out in about two hours, and the work was completed less than 24 hours after that. For the level of work done, an incredible turn time, IMO. All told, we had 5 different techs in our house between inspection and repair, and every single one was friendly, competent, and respectful of our home. While I'm not eager to *need* their services, if I do, MasterCraft Plumbing has definitely earned repeat customers here!

    Subject: Unresolved property damage and failure to honor warranty…read more I am writing this review to share my experience with Mastercraft Plumbers Inc. regarding a project that resulted in irreparable damage to my bathtub. While the company performed the initial task of removing a corroded screw, their technician's negligence resulted in significant, irreparable damage to the bathtub. Despite a written warranty guaranteeing workmanship, the company refused to restore the tub to its original condition, instead proposing an inadequate "refinishing" remedy that did not meet professional standards. After months of attempting to reach a professional resolution, I was forced to pursue this matter in Small Claims Court. On June 8, 2026, the Superior Court of California ruled in my favor, confirming that the company failed to meet its obligations and awarding a judgment for the full cost of the necessary replacement. I am sharing this factual account to assist other consumers in their due diligence. I have attached the Court's Minute Order and photographs of the damage for transparency. I am posting this as an addendum to address the owner's response. I wish to clarify that the facts of this matter were adjudicated in the Superior Court of California (Case #25SC04822C). On June 8, 2026, the Court ruled in my favor and awarded a judgment for the costs of repair, rejecting the defendant's claims. My review is based on these documented findings, and I stand by the facts presented. I have attached the Court's Minute Order for transparency to allow future consumers to make informed decisions based on the official record.

It began with Tony, who arrived on time, was extremely professional, and took the time to educate me about the different replacement options. There was absolutely no pressure, the pricing was very reasonable, and the estimate was prepared incredibly fast. Then came the installation. Hunter, Andy, Allan, and Jonathan were an outstanding crew. Four highly professional, knowledgeable, and hardworking people who clearly take tremendous pride in what they do. The job was done OUTFREAKINGSTANDING! From "Good morning" to "Thank you for your business," every part of the experience was professional, respectful, clean, organized, and educational. They explained the system, answered every question, protected the work area, and left everything spotless. The quality of their work speaks for itself. Just look at the pictures! The installation is clean, precise, and beautifully done. You can tell this team truly cares about the quality of its work and about customer satisfaction.
