"Needed to replace hot water heater and mentioned that when the service call was made and asked that they come to the house with the replacement. They came to do an estimate and wasted three hours after I approved the estimate as he had to go pick up the water heater."

"Such great service!! My water heater went out in my rental property and they were able to hop on the phone with me right away and offer me a quote. Within the next 2 hours someone was at the property - they removed the old water heater and installed a brand new one and were on there way. Cobra Rooter & Plumbing was professional and quick! Will use again in the future."

"High quality work, professional, trust worthy, took the time to explain everything to me; also educated me on my current hot water heater, pricing for a waterless hot water heater, & the issues related to my current gas hot water heater because of my water softener. I would highly recommend Jonathan Maynard from Tucker Hill Plumbing."

"I was highly impressed with the advice I received from Glenn, which I was advised to get with the home builder first to find out the specific cause of the problem with our tankless water heater, and then proceed from there to decide the action to take, if more additional work is required."

"Taden was extremely professional and walked me through every step. He went above and beyond. I had two "big name" companies come give me quotes for $3,000 to replace a $700 water heater. Neither of them offered to warranty the water heater that was only 3-4 years old and did not try and find the root cause of the problem. Taden not only took care of the water heater but also let me know the pressure to my house was way too high. After doing some quick research (I trust but verify), everything he said was spot on. I got a new pressure valve, hose bib, water heater and expansion tank for only about half of what the big companies quoted me for just the water heater. He also ran the drain for the drip pan without being asked to. 10/10 would recommend and will use him for every plumbing project moving forward. Thank you, Taden!"
