We bought a new home hoping to avoid the hassles of our past older ones with leaky basements and windows and insufficient insulation. We thought we'd found what we were looking for in the new home we bought which was about 90% done at the time, from a supposedly reputable builder. Almost 4 years in we are still dealing with defficiencies and poor workmanship, with the drywall alone being a constant issue. Tarion is a bit of a help but the lesson is take a very hard stand on anything to be corrected or it will take forever to get anything fixed!
