"KJM Plumbing, Kurt, responded quickly to my request for a quote on replacing our leaking water heater. He quoted installing a high quality, Bradford White unit at a reasonable price. The plumber who did the full installation was a very skilled, professional and friendly worker. The final invoice had no unexpected charges and included a nice breakdown of the major portions of the project. I highly recommend KJM Plumbing, for work in the Madison, WI area."

"No work was done. We had him come to our house to give a FREE estimate to fix our bath tub leak. It says free on Angie`s list. All he did was look at the ceiling and get info from my wife. I repeat NO work was done. We were charged $99 for a FREE estimate. If it wasn`t for that I may have selected them."
