"Professional, punctual, honest, kind, and very responsible service. I had my house softening and filtration system installed a month ago. I haven't had any issues whatsoever. He did a very clean and seamless installation. I love the fact he was able to install all the equipment in the basement and even took the time to do it so it would occupy the minimum space possible. I bought a water tester a few days after the installation, just to be sure, and to this day we are getting pure drinkable water from the dedicated faucet in the kitchen and the white marks on faucets and hardware from hard water completely stopped. I TOTALLY recommend Chris' srevice."

"The installation was done quickly and done well. The customer service was very professional. The only negative of this transaction was the cost of the project. It was the cost they told me it would be but I was just surprised that a replacement water softener system would cost that much. Overall I would definitely recommend this company."

"Kris and Dennis replaced my old water heater, which had "died" 2 days before. Their quality work was fast and efficient. They also installed an updated main water line shutoff valve to replace an old leaking one. Also, the office kept me updated on when they were headed to my house. The whole project was pretty painless, except for the unexpected cost of replacing the water heater, but I got a fair price from Rooter Guy. I would definitely use them again!"

"I recently hired Pure Water Services for a series of plumbing issues in our home that we purchased as a short sale and in dire need of repair. I couldn't be more satisfied with the service I received. From start to finish, the experience was timely and top-notch! First, they installed a new sink and disposal in our kitchen. The process was seamless, and the plumber was punctual, professional, and highly knowledgeable. He walked me through the installation, ensuring everything was done to my satisfaction. Next, we had a pesky shower leak that was causing damage to the ceiling below. Patrick quickly diagnosed the issue and made the necessary repairs. I appreciated his attention to detail and the effort to minimize disruption to our home. The leak was completely resolved, and weâ re relieved that further damage was prevented. Finally, we needed the pressure regulator on our sprinkler system replaced after the prior owner failed to winterize the system. Again, Patrick was efficient and thorough and ensured the value and system was functioning properly before leaving. Overall, the professionalism, expertise, and customer service provided by Pure Water Services were outstanding. I highly recommend them for any plumbing needs you may have. I will definitely be calling them again for future projects!"

"first jim needem was so professional, caring about my water situation. he immediately called me back and set up a service for a sunday. Ben came and i can not say enough about his patience,professionalism, caring and was so helpful with my situation. He took the time to educate us and help us understand the system. He checked all points of our water in our house. he also had some suggestions for the future which we will do. this company also has a person to extract water thru my insurance for my carpet. He left nothing out. His expertise and honesty was amazing. I hope everyone who reads this will use this company. If there were 20 stars they would definitely get them. I am so thankful for their customer service, and kindness. Thank you Jim and Ben colleen L in Broomfield colorado"

"I would highly recommend Brady (BC Plumbing) to anyone. I was thoroughly impressed with his prompt and excellent service on the install of my water main. His prices are more than reasonable. I admired his patience and ability to work with me as I accepted his offer in June, but did not get back to him until late September. At which point there was no delay in getting things done! Thanks Brady and your marvelous crew!"
