This is a great company to do business with if your looking for a good plumber. My shower in my master bath upstairs was leaking into my dining room. I called 2 plumbers and both quoted me an outrageously high price to replace a shower drain. My HOA referred me to Diamondback. I called and spoke to a supervisor Steve and explained the whole situation to him and how much my budget is for the repair. He told me they would work with me and set up an appointment. The plumber arrived at the planned time and was courteous and professional and the bill came in under budget. He was efficient and finished the task quickly. They did not try to "upsell" me anything, the biggest issue I have is when I am upselled something I don't need. I paid them off my debit card by mistake. I called them after I realized this and they were more than happy to switch the payment to my credit card. One word Professional. They are my new plumber anytime I need any work done. I highly recommend them to anyone needing a plumber
