I recently had a plumbing emergency that flooded my neighbor below. I called DiamondBack and they send me a technician. Nick showed up right away. He was very professional and explained exactly what happened with the plumbing. Nick made the repair through a very small cut in my new cabinets and he was able to save my brand new kitchen from being torn apart and saved me thousands of dollars! Nick is a true professional and I will hire him again and recommend him to others!

Apparently they think it's ok to park in Fire zones blocking fire hydrants and then when asked to move, like to run their mouths. Disrespectful, inconsiderate and unprofessional. "Please get me fired" he kept repeating. The attitude of people like this is the problem with society. People need to be held accountable for their actions. You can't do whatever you want in life.

Juan Carreon is the man! He drove within 45 minutes to us here at Century Grand and we appreciate him very much! He fixed our water heater in a desperate situation and for that we owe him a big thank you! Will most definitely use this company again! Service: Water heater installation
