Recommended Customer Reviews

Water was leaking from our wall into the basement, so I called several plumbers and leak detection companies. We were worried we had a breach in the mainline. I called Goldstar Plumbing based on a referral from an outdoor plumbing company. Adam spent several minutes talking to me on the phone, getting info about our home and its plumbing system. I could tell that he was knowledgable and just a nice guy, so I cancelled the other appointments I had lined up, and sent him a photo of the leaky pipe. He immediately called me back and helped me diagnose the problem as ground water coming in through the opening where the mainline enters the house. With some sealant, we were able to fix the issue ourselves and saved a huge amount of money. The leak detection company would have charged us $400 to come out. Thank you Adam! Most helpful plumber in the area!

Adam is a skilled and versatile plumber, and works and thinks like an engineer. He was able to help us install a tankless water heater in a small attic with only hatch access, remove the old tank heater using pulleys, and also install a concentric vent system with a custom elbow attachment. He also quickly installed an air gap on our kitchen sink including drilling a hole into a quartz countertop. And above all he is very responsive and reasonable with his rates. I highly recommend Adam and Goldstar for any plumbing job.

What do you look for in a plumbing professional? Knowledgeable, responsive, honest, professional, and competitively priced. Adam at Goldstar Plumbing is all that, and goes above and beyond.
We had a leak in our circulation pump, and requested quotes from multiple companies. Adam came recommended to us by another sewer plumber. Adam was quick to respond, easy to schedule, and was on time for both his free consultation and the actual appointment. Most importantly, Adam is knowledgeable, experienced, and explains things in a manner that is easy to understand. While on site, he pointed out a few other issues with the plumbing that are not code compliant, but gave us time to think through our plan and decide if we wanted the additional services. He inspected the completed work carefully and cleaned up the area. I highly recommend Adam and would definitely use his service again!

Adam at Goldstar Plumbing was able to come to our place immediately. We needed to fix a pinhole leak in some copper piping in the wall of our closet. He quickly diagnosed the problem, and spliced new pipe into both the hot and cold lines, to make doubly sure the problem was fixed right the first time. I highly recommend Goldstar.

4 times I have had Goldstar Plumbing out to my house. Once to fix another plumbers mistake, once for a literal emergency, once to install a faucet, and once to install gas lines from my propane tank to my generator. Not only is it professional in quality and design, but the call backs and checking in, the being open to communication, and the personable interactions make what can be a high stress situation, under wraps. What you need in addition to good craftsmanship, is a person that can keep you calm and help you feel like what is a current disaster, will soon be a tackled issue. 100% would recommend and will be using again.

We had new countertops installed and needed a plumber to install the kitchen faucet and garbage disposal and hook up the drain pipes.
Adam did a great job with the install and told us we need to have an airgap for the dishwasher. Since the countertop guys forgot to drill an extra hole, Adam drilled a hole for the airgap and installed one for us.
We are happy with the service and price and will recommend Goldstar plumbing to our friends!

Adam did an excellent job to repair the piping under my kitchen sink which had been improperly installed by a general contractor. He also fixed the loose faucet. Adam was responsive and quickly came out to service my home. I plan to use him for all future plumbing needs

The day we got the keys to our new house, the cleaners broke the toilet! Luckily we got a recommendation for Adam and he was able to come out right away and fix it! He also looked around the rest of the house for any other issues which, as a first time home buyer, was very helpful! He also made sure I got a receipt weeks later (even though I used Venmo) because I needed proof of the cost. Would highly recommend him!!

Adam replaced an old gas tank unit with another one. A very clean job that I'm very happy with. Adam was very nice, courteous , and thorough. I highly recommend Goldstar!

I'd give Adam 6 stars if that was an option. He was referred by a sewage company to fix our sink disposer. He came on time, was very professional and explained what needed to be done. He let us know the disposer could be salvaged, yet we decided to replace it.
He did the job quickly and charged us precisely what was quoted. He also explained how we can prevent future issues with the disposal, and left us a tool so we can adjust it when needed.
Recently, I had a pipe damaged from a screw. I called Adam, and he responded, FaceTimed me on how to turn the water off, and will be coming by shortly to fix it. I will post another review, but I feel confident he will exceed our expectations.
