replacement windows

am I on the right track? I am thinking of installing some replacement windows in a rental i have. The windows are aluminum windows that are drafty and full of miosture. the first floor is brick. Am I correct in thinking, takeing a sawsalll and cutting around them between the brick and caseing, leaveing the metal flange, then putting in the new window? On the top floor I am going to replace the aluminum sideing also. I should be able to use new installation windows there. Take off the sideing, install the new ones with the nail flange, then trim them in j channel and install new sideing. I have also heard to remove all glass pry up at the bottomlifting the old frame,cut with a sawsall where the frame is lifted and keep working around the window until it is completly taken out. Also what method is used to keep water from getting into the house from the top of the window? With a nailing flange I can see how it is weather tight. But with a boxed replacement window it seems like it could get in at the top. Do you make up flashing or is it just caulked all the way around? Thanks

The bottom floor -- another way to do it would be to remove the glass and the mullions, and LEAVE the aluminum frame in place. Order your new windows to fit THAT opening, with the exterior trim molded right to the new window's frame. You can cut the exterior trim as need so that the window will slide into the opening, and seal between the exterior trim and the aluminum frame. (Easiest way to cut the exterior trim is with a Skil saw, using a plywood blade installed backwards.) Once the windows are slipped into the hole, secure themwith screws through the vinyl frame into the framing of teh wall. If that is brick, use Tapcon screws -- predrill the holes.

The top floor -- If you use 'new construction windows, they will have a nail fin all the way around the frame. Water can't get past it. And with vinyls, you can order the exact size you need to fit the openings. Then, when you install the new j-channel and siding, you will be sealing the joint between the j-channel and the window.
