Nortec billed us for an extra hour of work for their plumbers to come back to fix a tap that they left leaking. The handle was put back on in a manner such that it did not line up properly and the cartridge would not turn off. I phoned to complain about the bill but they would not cooperate to resolve the matter. Since they take your visa ahead of time, watch out. They do not have fair billing practices and are dishonest. I would strongly advise you to look elsewhere. They are opportunists.
