Casement windows will not crank open




Hello,
Unfortunately, we do not have any technicians that we can recommend since we are an ecommerce parts retailer but a google search for professional in your area should provide plenty of options. As far as identifying your window cranks, we would need to see a top down photo with the window open so that the arms that move the window are fully visible.
If you think that some of the locks are broken as well, we would need to see one of the original locks fully removed from the window to compare to our inventory. We also offer the video below for similar situations but I'm not sure if you have the same type of lock.
