We were given the same message during our PDI... ensure that all upgrades ordered are present, check for major deficiencies, and learn about the overall working of your home (ex: HRV system). As we went through the house, other small deficiencies were noted with painter's tape, but not on the PDI form. This made us a bit weary too, but we were told that these items are better noted on the 30 day warranty form. I think it's also important to note that our PDI was only 2 days before closing, so there was little time to fix all of the paint issues and whatnot. A handyman was present during the PDI to do noticeable touch-ups as we pointed them out.
I have to really give it Mattamy, they are following through with what they said about the 30 day list (and we were skeptical!). We have since had 2 follow-up appointments to address items on our 30 day list. Yesterday was our second appt, which included several trades to fix things such as our fireplace, broken window, hose bib. We are impressed that Mattamy coordinated the trades to come on the same day, alleviating us from taking extra days off. None of our items have been challenged, and the warranty guys have actually pointed out additional deficiencies that we didn't see. After each appt, the warranty secretary has called to follow-up and book the next appt. She has commented that we are patient people. It sounds like she gets yelled at a lot...
Overall, we are impressed with the post-closing service. No, I don't work for Mattamy. I know people are quick to jump down their throats, however sometimes being nice and having some patience pays off... I've never been a believer in the "squeaky wheel" thing.
