"I had a break in my main water service line (from the meter to the house). They attempted to perform the lowest-cost repair first (snaking a new line through the existing pipe); when that failed, they dug out a new line and installed PEX from the meter. The folks I worked with were professional and very good about keeping me in the loop about their work status. At all steps of the way, I felt like they were doing their best to do things the right way rather than the quickest; they took additional steps such as making sure the PEX mating to the house occurred inside (i.e., where it was accessible) and installed a new ball valve, which would save us considerably in the future if we had a failure again. Working with them, I had confidence that they were doing their best to do this repair in the least expensive way possible; it was only when circumstances proved prohibitive that they moved to the more expensive option (running the new line). They also made sure to set us up with a temporary repair when it was clear that there was going to be a delay getting the boring equipment to dig the new line; I really appreciated that they took the time to make sure we were taken care of."

"The other plumber scheduled got called away but they showed up with two (2) other plumbers Kevin and Bob. They replaced faucet as it was dripping inside faucet and cheaper in long run to replaced and NOT repairs. They also replaced the hot water shut up valve and added plastic gasket and metal gasket to create a better seal. My handyman changed it out but not a long term stolution. They way they did the plumbing it is a perm. long term solution. If I continue to not fix I could have had a hot water pipe burst and could have cost thousands in water damage. Why I chose Winkles Plumbing. Quality work at affordable price. I tried others but they do NOT have the plumbing expertise. I been a homeowner for over 13 years. Many plumbers talk but only a handful of plumbers know how to really do the job."

"They installed 2 new water heaters with a circulation system to provide virtually instant and endless hot water. We went this route because our house is all electric and electric tankless water heaters arenâ t really up to the task. They also had to subcontract electrical work to supply the necessary power upgrade. We expected this to be a 1 day job, but the electrician didnâ t have everything required so it dragged out to a second dayâ ¦ meaning another day out of work so we could be there to give them access to the property. Then later when we tried to use hot water for a bath, there was only about 2 minutes of hot. Turns out the circulation system was installed backwards, so the circulating water was hot, but once the pipes were depleted, cold water was fed to the spigots. Disappointing, but to their credit, someone came out Saturday, diagnosed the problem and fixed it. Overall, mildly annoying and a bit careless, but everyone was friendly and responsive, and the end result appears to be just what we wanted."
