Recommended Customer Reviews

I highly recommend American Plumbing Guild to anyone who has a need for a plumber. They came out to the house and fixed all of our plumbing problems. (3 bathrooms!). They were so professional and courteous and we couldn't be happier with the service they provided us at a very reasonable price. Thank you so much. We have found our plumber for life!!

Thomas is trustworthy, skilled and very reasonably priced. He won't try and sell you any work or service that's not required. I've recommended him over the years and everyone who has used his services has been very happy.

Great every time. Efficient and fairly priced. Very trustworthy company. Highly recommend.

I bought a dishwasher from Costco but they were unable to do the installation. I'm sure glad I found American Plumbing Guild. He knew exactly what to do and what I needed with no hesitation. Our house was built in 1956 and had the original shut-offs. He put in new ones and we replaced the kitchen faucets while he was at it. Great work I highly recommend them. Thomas the owner and the plumber does it right the first time. I highly recommend him.

I highly recommend Thomas to everyone that needs a plumber. Most importantly, he is NOT A FLAKE. When he says he is going to be there, he is there. Also, he is super honest, has great and fair prices and he is very polite. I have used him more than once and am 100% pleased with his work. I will continue to use him as long as he is in business.

Really glad we went with Thomas for our recent plumbing issue. He was patient while we dealt with our insurance and worked us into his schedule on short notice. Like a lot of the other reviews mentioned- there's no sales pitch, no up selling, just an honest assessment about what he's working with and a fair price. His truck is clean and he shows up in a uniform. None of that really matters, but it just shows his attention to detail.
Being in real estate l'm especially happy to have found such an honest plumber to refer to all of my clients (along with friends and family). 10/10!

The owner, Thomas Mulhearn, was honest and did not overcharge. I was very pleased with his service.

I had a few plumbing issues that were annoying, but that I could live with. Anything was better than calling a plumber (so I thought). When my toilet started leaking with each flush I knew the time had come to get a plumber out to my house right away.
I was talking about my problem at work and a coworker said she had a great plumber and was so happy with him that she had her mom use his services as well. That was all I needed to hear and I gave American Plumbing Guild a call.
Thomas was able to come out the next morning. He showed up on time which is very important to me. He assessed and diagnosed the problem quickly, reviewed my options for fixing the problem (including how much $ each option would cost), and we came up with a plan. I had him fix those other annoying issues I mentioned at the beginning of my review as well.
Thomas REALLY knows his craft and was very honest and straightforward. I highly recommend him and will definitely have him out right when new plumbing issues arise!

Thomas came by way of a neighbor recommendation. I was very pleased with everything about his visit to fix a leak under my kitchen sink. He arrived on time, was very professional, explained what the problem was & what he was going to do to fix, the price was reasonable & the situation was resolved in a timely manner. Thomas gave me some quotes on other plumbing projects & I will be definitely having him return to do.

I received Thomas as a recommendation through a buzz group via social media. I was more than pleased with Thomas as he is very courteous, proficient, fair and most importantly HONEST!! Thomas came and resolved 2 plumbing issues I had, one was a slab leak. He made the repair with no upsale or ""talk"".....he is a very upstanding guy!! Would definitely use American Plumbing Guild/Thomas again!!....and HIGHLY recommend!!
