Gas line installation passed county inspection on completion day — photo updates provided at each phase of work
1 cited review
“Alpha Plumbing is phenomenal! They finished a delicate gas line installation on time and kept me updated every step of the way, including photos for each phase of the work. Dan Bateman and his crew are knowledgeable, professional, and courteous. The county inspector immediately approved their work.”
Frozen pipe call at 8am secured 10am appointment; correct solution found in single visit — plumber crawled through crawlspace to diagnose
1 cited review
“We called just after 8am, got a 10am appointment. Our plumber Logan was fantastic! Super knowledgable and helped us find the right solution for our frozen pipes. We will definitely be using them again! Logan deserves a raise for crawling around in our dreadful crawlspace and being a fantastic sport about it!!”

One reviewer rescheduled twice then received less than 1-hour cancellation notice before appointment — no advance heads-up given
“All I can say is good luck with getting them out to your property. I moved my schedule twice to accommodate them but they announced they couldn't come less than an hour before our planned time. Respect your customers enough to give them a 24 hour notice at least. Very irresponsible”

“Nice people but they didn't get the job done and took my money. It was hard to get on schedule with them because they work only M-F business hours. They replaced shower handles but then 3 months later the handles became loose and water wasn't flowing out properly. It makes a loud vibrating noise and water doesn't come out at all unless you play around with it a few times. I finally got them to come back to check …”

“Our tech arrived during the scheduled time and did a quick job. He showed us what the problem was and told us how he’d fix it, then showed us the end result. He let us know that he was going for the least expensive fix first and luckily for us, that first plan worked and we didn’t have to replace much at all.”
“Jon Davis showed up ready to work. He was very friendly, very personable and very informative. While he was busy installing the disposal he was also telling me about the disposal and how it works. He sure knows his business! All in all I give him 5 stars for the great job. Thank you Jon and Alpha Plumbing”
