if you are putting up plywood... PlyLocs work pretty well for inset masonary windows, just have to get good measurements ...if you are screwing to wood frame use the #25 TorX headed deck screws, as they are easier to remove...if you have time, put a coat of paint on the plywood, especially the edges...mark the location before you remove...shut off water,gas, pull breaker on the power...take a good video inventory of anything you don't take with you...would suggest good amount of cash as disabled phone junction boxes interrupt credit transactions...good rain gear and a couple of towels, LED headlamp for everyone...if you are not used to flooding and working in wet shoes, have a way(Teva sandals/shower flip flops)to allow your feet to dry when possible...good luck
