Nickason Plumbing and Heating installed the water system and Heating system in our new home. The products they supplied and the installation work are excellent, however, their after sales service has been less than poor. I have a small problem with the shower in the washroom. I have left four messages on their answering machine during normal business hours and have yet to receive a return call. I experienced this same thing on a previous call seeking information about our new furnace.
