"In shopping for help to install an Amazon purchased sink and faucet some plumbers were unwilling to provide an estimate, in alleging an inexperience in working with the specific model of faucet. Brian provided a fair estimate, and then completed the work with expedience. He also agreed to replace an aging water intake valve requiring coordinating his efforts with a water company team charged with locating, and shutting down the water supply at the street level. I soon thereafter hired Brian to install a bathroom vanity and faucet for a second bathroom. This time the Amazon purchased faucet turned out defective. Brian quickly ordered a similar faucet from Bender Plumbing of Bridgeport where he is entitled to 33% discount; this helped to keep the cost very reasonable. One week later I called upon Brian to replace my aging hot water tank with a Benders Plumbing provided quality tank. During the installations I felt comfortable leaving Brian alone in my semi upscale home, as I needed to exit the house to run errands. Several weeks following his work I conclude that the plumbing upgrades were one of the more valuable investments I have made for my home. I recommend Brian to anyone seeking quality work at a reasonable price, and suggest having him purchase needed plumbing hardware, as he commands a significant discount from area plumbing vendors."

"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."
