Crestline does NOT stand behind their junk windows, they make excuses instead of fixing the problem/s. We have had troubles with Crestline windows since the day we picked them up from Menards (they also do not stand behind the windows) the windows Menards shows in the store are not the same quality you get when special order. the windows were cheaply wrapped with no protection. We've had the repair guy over 3 times, (he's more like a mediator) . Here's some of the problems we've had in the first couple days/weeks/ months:
Bowed frames, 2 bowed window pane frames (cut wrong), frames out of square, twisted frames, broke/uneven mullion joint, bad springs (can't open), 2 cracked window frames inside and out, bad seals VERY leaky, bad locks, MAJOR ice/water build-up, so bad that water runs down onto our jambs...and not because our house is too humid (they like to say that to put the blame on you)
These are a few of the problems we've had in the first 6 months, I can't wait to see what the first year brings. Don't buy Crestline windows they are JUNK!, we learned the hard way and for what we payed for "special order size" windows (which we found out later that 4 of our windows were stock sizes and Menards charged us a special order fee) we could have bought much better quality windows, and not to mention the money we have to spend on replacing the seals/weather stripping on the windows. I have seen where many others are looking to file a class action suit...I'M ALL IN!!!
