We recently had a new patio door and palladium window from Ostaco, purchased and installed by VanDolders in Collingwood. Can t say enough about the quality of the installation and the repairs that they needed to do to prepare the opening. A bit concerned about Ostaco's quality control however. A couple of weeks after the install I noticed water dripping inside the house from the bottom of the window insert. I noticed a couple of gaps on the outside moulding so I called VanDolder, who were quick to respond. The installer who responded took off the inside moulding and commented that none of the screws holding the outside trim were tightened properly. In fact, one screw was even missing. Fairly simple fix and the door looks great but given Ostaco's obvious poor quality control we have fingers crossed that there are no unforeseen problems down the road.
