ordered and installed 16 premium vinyl windows in my home may of 2019. They arrived ok. upon installing I noticed a few had streaks inside the sealed double pane glass, and these were upgraded to tempered glass. Issue is the partial window stops that flip out end up breaking off as they flip out by themselves when you close the window, upon opening up again the window catches them breaks the spring inside of breaks the lever off. Happened to two windows the first week. Trying to replace by warranty is non-existent, several emails and no response. So I go on their website and order the parts needed, paid for them, weeks later I get an email stating the parts are on backorder. I finally get the parts, which are nothing what I ordered, don't even match the part numbers on my order and not even the correct quantity. Several emails later- NO RESPONSES. So now I have 3 (3 month old)windows with broken parts that I cant get parts for. what a joke, mistake with this company.
