Recommended Customer Reviews

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!!

I searched for a good and fair plumber, and Thomas at American Plumbing Guild came through as recommended by members on my community FB page. He was skilled, efficient, personable & fair.
Beyond a 5-star review, I'm not sure what else I can say. (Yelp wants a longer review) Oh yeah, he's clean and neat too! (Say no to crack!)

Thomas at American Plumbing Guild does excellent work. I've been using American Plumbing Guild for about 6 years for residential and commercial work around LA and OC, and he is always fair, quick, responsive, and does a good job. I don't do Yelp reviews until I've gotten consistent, quality service from a company for YEARS, and that is what I've gotten from American Plumbing Guild. I strongly recommend them!

Thomas did a great job helping with clearing out my main and also helped fix a few issues with running toilets. Thomas was very professional and did excellent quality work. American Plumbing Guild comes highly recommended!

Tom was very professional and went above and beyond to assist me with a complex plumbing issue due to restricted access to the water leak.
I will call him again in the future.

Water heater went out in my apartment and called this company and Jason came out quick to fix the issue and we are very happy with the service Jason provided us. I recommend him to anyone who needs plumbing services. The price was cheaper than other services but the quality is great. Give him a try and you won't be let down.

As always, when I need something done right, I go to my handy Yelp app to find the right company for the right job! I am so thankful to have found Thomas. He arrived when he said he would and diagnosed every problem I had in the house....we're talking about 2 leaky toilets, bad dual shower heads that didn't distribute hot water evenly....and a missing sink cap that was out of production. Most plumbers say they need to order the part and you don't see them for another week or two...not Thomas! He left my house and went to a hidden warehouse somewhere and showed up with all the parts needed to repair everything....I mean everything! He arrived at 11am and left at 3pm with everything in working order! He even re-caulked a few places that were loose but I had forgotten to tell him! Talk about A+ Service! I'll be sure to look Thomas up again whenever I need another plumber...and so should you! Thomas is a Yelp jewel in my book!

We were looking for a skilled plumber when our Rinnai Tankless started to leak. And we found the right person! When Thomas showed up, he was right on time and was very kind. His prices are fair and you can tell he put time into his work and got it done right the first time around.
We will definitely use Thomas again because he's the owner and he takes pride and is craftful.
Thank you Thomas. Hope we don't need you again soon, but if we do.. We know your number!!
Friendly, methodical with his craft, & is a smell good plumber! All pluses!
