I purchased a new Mattamy townhouse in October 2016 in Oakville. It developed serious roof leakage within a few of months of taking possession, causing water damage to all three levels of my home. In mid 2017 Mattamy attempted to repair the leaking roof and interior damage resulting from such. They never advised what had been done in the way of repairs in spite of my request to know. The roof began to leak again in 2018 and continues to do so as of now, in June 2019. Their customer service group is extremely difficult to contact and when you do manage to reach them they are very non-reactive and poorly responsive. They have a list of excuses as to why they cannot find and resolve the problem, ranging from weather conditions to lack of people and time, etc. Now they claim that there are so many issues with water leakage and other defects in construction that their repair crews are overwhelmed with work. They cannot give any kind of a time frame for making the repairs and when they do get around to it they will not give any kind of a report as to what they find and what they do to repair. They say they just do not have the time or resources. On my street and in my area alone there are several homeowners going through the same issues as I am, with leaking roofs, and these homeowners are being faced with the same negative attitude from Mattamy. Meanwhile Mattamy continue to sell and build new homes at a feverish pace. I have purchased new homes from other builders in the past and never have I been treated with such unprofessional and unacceptable service. Additionally, the workmanship has proven to be of the poorest quality. I would caution anyone who is considering to purchase a Mattamy home to rethink and go elsewhere. If anyone can offer advice to help me in resolving this situation it would be very much appreciated. Also, if there is anyone else out there having the same or similar issues with Mattamy, please voice your concerns.
