Recommended Customer Reviews

Conscientious, smart, fair priced. I'm in the trades myself and frequently my clients will ask me for other service professionals. When they ask about a plumber and it's south of north Austin, I always tell them Union Jack!

Nick was fantastic and on point. We needed a new bathroom vanity faucet installed and he knocked it out quickly and efficiently. He even corrected a few issues with the previous install and made everything right. He's reliable, honest, and experienced. I'd highly recommend him for any plumbing repairs/installs. He was excellent!

I recommend Nick highly. He's prompt, efficient and reasonably priced. And he appears to really know what he's doing. I've used him two or three times over the years and highly recommend him.

I used Union Jack Plumbing to fix broken shut off valves and change a faucet. Union Jack did both very quickly, correctly, and for a reasonable rate. I would use Union Jack again.

I was very pleased with the service provided by this company. He installed new plumbing under my kitchen sink and moved the gas pipe which was too high to allow the new new range to be placed flush against the wall. Everything was done in a quick and efficient manner. Needless to say, Union Jack is saved to my contact list :)

If you need a reliable, honest and experienced plumber, I couldn't recommend him more! Personable, informative and efficient. Hire him!!

Jack has always been responsive, honest and hard working. Really appreciate having his expertise.

Nick was friendly, very knowledgable, communicated great and fixed our multiple problems in an efficient manner and affordable price. Highly recommended, even if the Yelp algorithm may not say so...

I've never met a plumber, or any repair guy, as good as this guy. First, he can fix frickin' ANYTHING. Second, he does it fast, and has the parts with him. Third, his prices are usually lower than other estimates. He responds to service requests right away, even if he can't do it (a rarity), and he gives you a one-hour arrival window (not two, not four), and then arrives on time, every time. The first time he came, he took less than an hour to fix the problem, but since I was paying for an hour, he spent the rest of the time going around the house fixing other little plumbing issues until his time was up. He's polite and explains what he's doing quickly and clearly, and why you might or might not choose to do some repair. I've never had a better plumber, I can't recommend him highly enough.

Nick is in high demand for good reason. He's been our go-to plumber for over 20 years! A fountain of knowledge, top-notch work, and such a pleasant fellow.
