Recommended Customer Reviews

I have used this company for many years. Nick Green, the owner provides reliable and honest work. He listens to the customer and goes the extra mile without even being asked.
I highly recommend Union Jack Plumbing to anyone looking for plumbing services. You won't be disappointed!

Was able to come out quickly. Fair and honest. I highly recommend Nick and will use his services again.

Nick was so helpful! I sincerely appreciate his thorough check on my kitchen faucet. He quickly and efficiently solved the problem, fixed it and double checked it too.!!!!! I highly recommend him.

I hired Nick Green from Union Jack Plumbing to uninstall my kitchen sink prior to my countertop installation. He was then asked to come back two days later to reinstall my new sink, faucet and hot water dispenser. I want to go on record that I had a really positive experience working with Nick. When he came out the first time to uninstall my kitchen sink, he made some recommendations that really made a big difference to me. He knew I was getting a new sink so he advised me to buy a new sink assembly kit so that I would have a new stainless steel ring with my new sink. I had not thought of that. I actually did not realize how that would make a big difference in the look of my sink. He also noticed that my filter for my hot water dispenser needed replacing so I was able to order one from Amazon overnight. My installation went smoothly and I was totally pleased. Nick is very knowledgeable and experienced. He takes the time to understand what you want and not only comes prepared to accommodate you but will help you make sure that the final result will be what you want. I couldn't of been more pleased. Nick is now on my preferred home vendor list.

Nick is amazing. Showed up early, walked Me through his process, and got everything done quickly even though it was cold and rainy. Explained the issue clearly and got the job done. He's quite the character too. He's our go-to guy

Very professional and straightforward. Very helpful answering questions and explaining things.

I can't say enough good! He was so helpful in guiding me through the process of getting the correct fixtures before he came to install. If he hadn't I'd have had the wrong parts for our bath remodel. Friendly and professional. He wore a mask the entire time working which we appreciated for his safety and ours. He was on time and reasonable prices. We will use him again.

Needed a bathroom spout replaced, had been installed poorly by DIYer. Showed up on time, was very friendly and informative about the job, said that because the job needed some soldering it would cost a little more than usual. Job took exactly one hour and the charge was 280$. part installed was a 35$ part. I know that plumbers are expensive but 250$ an hour seems pretty steep.

Very expensive. Ask for quote before you give him the job. I ended up paying up to $135/hour

Nick is the BEST. We hired him to unclog a sink, and replace a faucet in the upstairs bath. My husband had tried Draino and Liquid Plumbr, two different snakes, plus a good old fashioned plunger with no luck. Nick had that clog cleared out in less than 10 minutes! Friendly, fast, fairly priced, and in the time of Coronavirus, I am happy to say he wore a mask to keep him and us safe.
