"From start to finish Front Range Water Heater was a pleasure doing business with. Audrey was friendly and answered all my questions prior to setting up the appointment. When Tim and Justin arrived we went over the water heater installation and other repairs before beginning, once again answering all my questions. All the information was very welcoming. I could not have asked for more skilled technicians to be working on my home. I had a few other plumbing issues other than the water heater installation which were absolutely no problem for Tim and Justin. Before I knew it they were done with the entire job which was almost incredible for the amount of work being done. I’ve never had this good of an experience with a plumbing company before and will absolutely be using them for any future needs. I will also be recommending them to all my friends and neighbors. Did I mention their prices were also extremely competitive and realistic? I spoke with other companies but the choice was clear. Front Range Water Heater was the clear winner. No hesitation."

"Installed new water heaters. Provided option for tankless system vs. traditional system. Given the amount of work and cost it would take to convert to tankless, chose to remain with two tank system. They were quick, clean and professional. Would recommend and use them again."

"Tim, the service personnel from Front Range Heater and Excavation, removed the prior and installed the new water heater, I felt fully informed during the process, as well communicating in friendly and professional manner. Tim educated me about possible pilot lighting and left the space clean upon leaving."

"Precision Plumbing has been our â go toâ for decades. They are prompt, professional and do a great job. Our furnace was at the end of its 15 year life. Within a day we had a brand new 30+ year furnace installed. They were quick and efficient. The job site was spotless when they left. Thank you Charles!"

"Our hot water heater went out recently. It was 12 years old, so we knew we needed a new one. It took quite a bit of research to find a reputable company that didn’t have exorbitant prices. Other businesses told us things like: we needed all new pipes. (We didn’t.) A new hot water heater would be $3,000 to $5,000 plus labor on the of that. ( way overpriced), etc. Finally, we found an excellent smaller local company. We went with Pure Water Services in Loveland. They’re honest, reasonably priced, and absolute pros. They were able to get us scheduled for a new hot water heater within days . Their master plumber Patrick was courteous, extremely knowledgeable, and very thorough. Patrick is an impressive and experienced plumber. Alexander keeps in touch daily with every step of your project repair. I was impressed with how kind, and professional he is to customers. We are so thankful to have hot water again. They stand by their work. My husband and I highly recommend them!"

"Brent was amazing. He not only cleaned the tankless water heater but also did a thorough checklist of the plumbing outlets, ordered, picked up & installed a faucet that we have long been waiting to replace. He was very fast, efficient, time & cost sensitive & professional. Thank you so much, Brent for a superior job!"
