Use a hammer or a drill to take out any nails or screws that are holding the window in place.
Install new windows without removing siding.
Replacing both at the same time allows your contractor to set the windows and then install the siding which can end up saving you money in the long run as well.
My question is how can i remove the old window without taking off the siding.
I had windows done for me once professionally years ago and somehow they cut the old flange from the old window and were able to remove the window leaving the flange and without disturbing the siding.
Attach new pieces with screws and wood glue.
If you find damaged or rotten wood remove it and cut new wood to replace it.
For the new windows they cut off the flange from the new window.
Insert replacement windows aren t the best option in my case due to the construction of the old aluminum window frames.
Sometimes there are little pieces of wood between the window and the wooden studs that hold the window tight.
Rather than removing the siding installing the windows and re applying the siding over the flanges i am considering cutting the siding such that the opening is large enough to allow the windows to be secured directly to the framing then using 1 1 4 strips of siding over the flanges just as spacers and then applying 1 x 4 smart panel molding around the windows which would hide and overlap the strips.
Capping a window correctly is important as this aluminum or vinyl framing helps direct water away from the frame and the interior of your walls.
If you want to fully replace with new construction windows you will have to deal with the siding.
Installing siding once it s been cut to.
Caulk any major voids.
Nail into place either new siding ripped to size with your table saw or the existing siding if not overly damaged and install over the new window s flange to the edge of the existing siding.
To the edge of the window to about 1 past the outside seam.
With window tape cover up all seams.
The pieces of siding being installed adjacent to the new window should be held in place marked and then cut allowing 1 4 inch of space for expansion.
Fill any holes with wood filler and make sure you have solid wood where you ll screw the new window into the frame for stability.
1 full frame or prime replacement window where you tear out the entire existing window frames and all down to the rough stud opening and insert a whole new window with exterior frame and header and sill and all into the rough opening totally replacing the existing unit except sometimes reusing the interior trim to retain a match with other windows.
