Pella

I bought 9 replacement windows (4 being mullioned double windows). I made it the 5th window before I finally saw one with the screw holes drilled properly. The first 4 were all drilled straight through both layers of vinyl. The fifth one, only the two in the bottom half of the window were drilled correctly through the top layer with the bottom layer in tact to hold the screw in place. I still have yet to come across one where the horizontal muntins (I believe is the correct term) weren't cut about 1/8th inch too long. We paid extra for the auto closing locks as well. They don't work for crap on double hung windows, so save your money. Pella also installed them like they whoever was doing it was blind, drunk, or both. So far half of them hit the notched out vinyl on one side or the other. Then the locking mechanisms... one came with the plastic cover broken as soon as we unwrapped it that I still have to submit a warranty claim for. But almost none of them are even centered enough to work properly. I know, you're thinking "Just shift them over, the screw holes are slotted for exactly this reason." Yeah... If they had put literally any effort into centering the screws in the slots so they could be shifted. Every single one of them have the screws on opposite sides preventing any adjustment. Luckily, I'll probably be selling the house in the next few months so I won't have to deal with these windows too long. But this is the first, and most likely last, time I'll ever buy a Pella window. I've never spent so much on trash in my life. We even opted for the 250 "Mid-grade" series to try and avoid these problems on the lower grade series. At this point, I assume if we would've gotten the lower grade windows... We probably wouldn't been shipped all the pieces 'with assembly required', which honestly probably would have given me a better product than what I received. 0/10 - garbage. I didn't take pictures of the mounting holes. But here are a couple of the locks and the muntins.
