Recommended Customer Reviews

If you live in Huntington Beach. If you need a new toilet installed or any other plumbing service.
Go here. Go see Thomas. Don't waste your time anywhere else. It's as simple as that.
If you have a plumbing need and you want it handled quickly, cleanly and efficiently, talk to Thomas. He was fast, knowledgeable, precise, friendly and very attentive to detail. Our new toilet is now installed and he removed the old toilet and took it and all the packaging for the new toilet with him.
I did not have to do anything (short of purchasing the new toilet). Thomas had all the correct hoses and hardware and wax seals.
Thank you Thomas. Really glad a family member recommended you.

I just want to commend Thomas Mulhearn from American Plumbing Guild for his honesty, straightforward, and customer service-oriented attitude. Recently, I discovered a sneaky leaking in the freshwater line that feeds the washer machine. After several inquiries on local plumbing companies, yesterday I decided to call Thomas Mulhearn at American Plumbing Guild (I got this referral through my Chiropractor Dr. John Bair)
Thomas sent Daniel who is a professional Technician Plumber. Daniel quickly evaluated the situation and proceeded to fix the problem efficiently and with extra care.
I'm glad I contacted American Plumbing Guild.
I will consider this company for a couple of future projects.
Thanks again.

I couldn't get my Home Warranty or the plumber they recommended to actually show up to fix my leak in a copper pipe, so I checked Yelp and found American Plumbing Guild. Not only did they return my call immediately, but they gave me a quote the same day, sent someone to fix it the same day, and the final bill was exactly what the estimate was. We have a new plumber now.

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.
