We called for a checkup. When Timothy showed up he found rust on the disposal and on all three water heaters. He gave us pricing on the spot for regular water heaters and the tankless. We replaced the disposal with a commercial grade unit and had him replace the hoses on the washer with stainless steel. We could not be more pleased with the service and advice. The price was a little high, but we know we got a good job and are secure for several years.
