"We contracted with High Five Plumbing to purchase and install a 40 gallon water heater to replace a 21-year-old unit. Our experience with the company was terrific. Members of the office staff were cordial, helpful, and professional, providing options and information, following-up on appointments, etc. Caleb, who installed the water heater, is a real pro and a good guy who answered all our questions and provided a thorough explanation of the various services offered by High Five. He is a credit to his company. We didn't have a plumber on our contacts list. We do now. Cliff Foster, Denver"

"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!"

"Tyco is simply the BEST. A company and people who are genuinely good. I couldn't ask for a better or more honest plumber. Tyler is fantastic, and Rich and Mike are outstanding. Seriously, they're there when you need them and you never have to worry about if they're being honest. This is a company that values their customers and the relationships built. Tyco has done multiple jobs for us. They've installed a tankless water heater, cleaned out drains, fixed faucets, installed toilets, and more. Seriously, if you are reading this, you're in need of a plumber. Stop looking and just call Tyco. You'll never have to search for a plumber again. Thank you, Tyco!!"

"EZ Repair does it all…from plumbing, electrical, HVAC and handyman tasks…It’s really a one stop operation. The difference between this company and others is that when you call EZ Repair they are out to your home or business the same day if that is your request. Best of all they are fairly priced. I think everyone who works at this company must enjoy what they do because it was obvious to me. Their customer service was excellent! I would highly recommend using their services."

"Jim did a great job installing my water heater. He also repaired a washer leak and water connectors. I would highly recommend him. He was fair and reasonable, high ethical standards. I certainly will call him again if I have a problem. Thank you Jim......"
