I bought a home from mattamy just over 2 years ago. Since then i have had 2 external-internal leaks. The front of our house has a porch that covers the two front windows and front door. The roof was leaking causing water to pool down into our windowsill. Also inside the wall and down to the carpet in front of the window. The warranty people are very slow and dont seem to care that people spend hundreds of thousands of dollars on their homes. Also my bathtub in the top level of the house drain leaks. Having water drip down all the way to tne basement. Mattamy came over a month ago to diagnose the problem. They cut a hole in the wall behind the bath tub and told me that the drain pipes had never been glued together. Instead of just gluing them quick while they were here and fixing the problem they said they would have to get back to me. Irs been over a month now and 1 of my 2 showers is out of order. I would highly recommend not building with mattamy as the builders are terrible and seem inexperienced. Ie not checking drains for leaks before drywalling everything shut. Im not the only one with problems. The most parhetic problem i have encountered is at my brothers home. When they installed his stairs leading outside from his sliding patio door they installed them on the wrong side. The door only slides open 1 way. After ge notified them of their pathetic mistake it took them over 3 months to fix the problem and his house wasnt the only one that had tne stairs mounted the same way. SAVE YOURSELF THE HEADACHE AND DONT BUY A MATTAMY HOME LIKE I DID.
