Proskill installed a new water heater with pan drained outside. Greg and Jamie were competent and professional in their work and interaction with me. They had some difficulty getting the drain outside because of a large metal bracket that was in the way. On the third day they succeeded but did not charge me because of the delay and inconvenience. I did not ask for this courtesy; it was extended to me unsolicited. I was very satisfied with the work of proskill and I recommend them without hesitation.
