"What a great experience! I needed a water heater replaced ASAP, and Mike and his team replaced the heater quickly, with no issues, and at less than half the price of the next lowest bid. I'd highly recommend Mike's Plumbing."

"While out of town, got word basement might be flooded. Called Schede to check boiler and hot water heater.. They went out the same day. Discovered sump pump wasn't working so replaced it. Cost pump and labor $800. Over the years they have responded to many problems, leaking faucets and stuck drains. Biggest project replace boiler for steam heat. Took 5 guys to wrestle boiler down a narrow basement stairway. Patient with a few family disagreements. Nothing to do with them. Installation successful. They've always been prompt courteous and non judgemental when encountering crazy working conditions. Think they are great. Boiler and hot water heater were fine. They installed both."

"I cannot recommend Mark more! We called him for a dishwasher installation and pipe repair. He quoted us reasonably - and was generous with his work and time when what we thought was a simple job turned out to be much more complicated. He was absolutely a pleasure to work with - communicative about the issue and his solution, flexible with scheduling, and just an all-around nice guy. We will not be hesitating to call him in the future - our go-to-guy for all plumbing needs."

"Within a minute of requesting a quote, Tony called. Said he would come the following morning and look at the water heater. Less then 24 hours after that I have a new water heater at what I believe to be a very fair price."
