"I was expecting to have to wait a day or so before I could get my water heater installed. Instead, I had a new one delivered and installed within a couple of hours and the price was better than what others were quoting. Excellent service!"

"Kevin was very helpful and explained everything. Price was less than the big companies I talked to. Took only two hours and he took the old water heater away."

"He showed up and assessed the space, adequately recovered tools and everything needed for the job, and was quick and efficient - answered all of my questions and didn’t feel like a hassle asking them. Will be calling these guys anytime I need any plumbing work done!"

"The repairmen was very professional and experience in his craft, I was shocked at how fast they responded to my request. It is a known fact that electricians,plumbers, carpenters and etc. are very expensive, but three or four hundred dollars to replace just a water faucet is entirely to much. As stated previously, I hired them to replace my air conditioner and they did a masterful job."

"I had a water heater fail on a Sunday morning. I submitted a request and got a response in less than a minute. The person was extremely helpful and we arranged an install only a few hours later. I couldn't be happier with the service and attention to detail."

"Justine from Prostar was very knowledgeable and professional. She gave us great price options and followed up after the installation to be sure we were happy. They were on time and did a great job! The technician thoroughly explained what they were doing and how long it would take. We had several quotes/options, but Prostar Water definitely provided the best product and service for the money!"

"Awesome! This is the second time I've called BCP. James checked my water heater for a possible leak and checked the igniter switch. He called the mfg to discuss the switch and to handle any warranty coverage. We learned that what we thought could be a problem wasn't a problem after all. Thank you so much James and Adam for going the extra mile. You're my permanent plumbing resource!"
