Seeking repair of a leaking water supply connection and shutoff valve to a pedestal sink along with a leaking faucet handle, I entered info on GEM’s website this morning. I received a prompt callback from Gena who was friendly and helpful. An appointment was able to be arranged for about 6 hours later. The plumbers Joe and Baxter arrived on time and took care of all the problems in a professional manner leaving their work area and sink perfectly clean. This was the first time working with GEM. I was quite impressed and would certainly seek their help should the need arise.
