Stay away from York Mills Construction. They will do a great job of selling you on their work and the warranty they provide but it’s all a false. His "crew" did a horrible job replacing our roof. There’s roofing nails exposed which are already rusting, shingles that are curling up already (even though the roof is only 1 year old) and shingles that are not installed properly as they are not overlapping each other. I have tried calling Zach back multiple times and he doesn't return calls from his cell phone or from his office. When I finally tracked him down he told me he would come and check out or problem but that again was another one of his lines.
Lastly, I wish I would have checked their office address. Their mailing address is a post office box at a Shoppers Drug Mart so you have no way of actually tracking them down at all. Stay away from these guys or face being ripped off like we were.
