Recommended Customer Reviews

I highly recommend Nick for any plumbing needs. We needed a kitchen faucet replaced and a bathroom faucet repaired. He spent a considerable amount of time on the phone with me, helping me to determine what went wrong, what type of faucet to look for and how to maintain it. He asked for a pic of the bathroom faucet ahead of time, so he could come as prepared as possible to do the repair. This kept him from having to leave the job on the clock to purchase necessary materials. He is extremely knowledgeable and efficient. I plan on calling him again for any plumbing needs that arise.

An A+ recommendation for Nick! Replaced some leaky pipes under the kitchen sink, cleaned out the disposal and replaced my faucet. All in little over an hour! He was quick, informative, and affordable. Also no problems driving out to Round Rock (no extra fees).

We have used Nick at Union Jack Plumbing for a number of household jobs over the years. Most recently, he installed our fireplace gas log set and we are delighted with the results. He takes pride in his craft and does a fantastic job at a fair price. In addition to being very good at his trade he is friendly, punctual and has excellent communication which really matters when you have plumbing emergencies. We wouldn't think of using anyone other than Union Jack Plumbing and highly recommend him.

I did have Nick come out to repair a drippy outdoor spigot and he did an excellent job in a short amount of time at a very fair price. My 5-star recommendation remains intact & I definitely recommend him.
Because he is good & no doubt very busy, he may not be able to do your job in the time frame you need, so hopefully your situation and his availability will match up when you need work done.

This guy is a pro. Even though he doesn't do the scope of work I needed, he called me back the same day and left a good referral for me to call. You don't see that level of courtesy often.

Nick showed up on the agreed to time and date and proceeded to identify my commode problem and correct it . The process took about an hour and the price I paid I believe was reasonable.
I would certainly call him back for any plunbing problems.

They don't make 'em like Nick anymore. I had a low-pressure issue in my master bedroom shower. Nick asked lots of questions on the phone, so that by the time he came to the house, he already had a very logical game plan. He explained exactly what he thought the problem was, what he was going to do to fix it, and plans B and C in case his first plan didn't work. 20 minutes later, problem solved. Had the best shower in a long time this morning. :) Nick is the man!

Nick was the first company to call us back out of the 5 I called. He was prompt, friendly, explained everything to us, funny, excellent work, sweet sweet man. We have found our new Plumber and will proudly recommend him to anyone searching for a plumber.

Nick was able to help me over the phone free of charge! He thoroughly explained how I could get my diamond earring out of the kitchen sink drain where I thought it was lost forever. It went all the way down into the pipe in the foundation and we were still able to retrieve it with Nick's expert guidance. You're the best Nick!

Found Union Jack Plumbing through Yelp and I couldn't agree more with the positive reviews.
Nick fixed our issue that another plumber said he couldn't fix. The price was fair, he was clean and friendly and timely. Not sure what more you could ask for.
