Our Mattamy experience has been horrendous. Right from during the construction stage to after three month moved in. The changed our floor plan and outside elevation without even bothering to let us know. They made it cheaper and less appealing. We needed to change to closing date to be able to sell our previous home and they would not accommodate us. The previous builder had not problems doing this. Mattamy was so stubborn about this and it really made it difficult to sell our house. The customer service is like talking to a politician, they talk a lot but don't help, lot of promises but nothing done. They are just interested in building the house quickly and getting your money and moving on to the next house. They pay no attention to the quality and have terrible customer service. Dealing with the deficiencies has been a nightmare. We have to take time off work and when they finally come, they don't fix everything and have to came back and come back. They do short cuts to finish things quicker and many things are done very poorly. There are some homes that people could not buy because of the mortgage rule changes and defaulted on the home. Mattamy then upgraded these homes with central air units, garage door openers, upgraded lights, appliances, back splash etc. These homes were similar in size to ours and sold for $300K less than what we paid. After all this, we ask for a small favor and they basically just tell us to go away. I don't recommend buying a house from Mattamy.
