Unfortunately, I am forced to use this plumbing company by my landlord and would never choose to work with them again if I had a choice. Their lack of professionalism and communication has been awful. They were approved to come on a scheduled day and then failed to communicate if or when they would return. We were left without working toilets for several days, and I had to call their main office myself just to get a vague timeframe, which they then did not honor. They showed up unannounced, including on a Saturday night, without authorization. When my employee arrived the next day, our business had been left in unacceptable condition: mud tracked throughout the studio and smeared all over the bathroom. This is a client-facing business, and leaving a space in that condition is completely unacceptable. They also claimed work had been completed when it had not been and repeatedly showed up without notice. The lack of accountability, communication, and basic respect for a tenant’s business is alarming. Trashing an active business, leaving it dirty, and disrupting operations is not how any professional contractor should operate. I would strongly caution any business owner against using this company if you have a choice.

I live at Capri on Camelback apartments. The apartments use Diamondback Plumbing as the plumber for the complex. I have been trying to get a leak fixed in my bathroom that is coming from the toilet in the apartment above me for two weeks now. The plumber finally came last night. He cut a hole in the ceiling and then left saying he would be right back. It is now the next morning and he still hasn’t come back and the leak is still going strong. I have had no additional communication from the plumber. The apartment complex said that they found out that the plumber had left the complex without telling them. Diamondback didn’t contact me or the apartment complex. Terrible communication and service!! Wed
These guys charged me over $700 for a 2hr. Job fixing a meterbox leak. After materials it was like $300 a hr. Wow in flagstaff plumbers are around $140 hr. Still looking around for reasonably price plumber . Tech was good though . To bad they overpriced.
My rental's Management Ompany uses a variety of contractors, most mediocre at best. This time they called Diamondback Plumbing to help fix a leak....... Requiring more than two visits, these guys diligently took their time figuring out what the real problem was. Brandon in particular was a pleasure to deal with- texting me his arrival time, explaining what the different issues might be, . He even found an innovative solution for me while a specific part was ordered. Offering 24/7 service, extremely knowledgeable, and dependable, these are the guys to call if you need help!
