Install New Windows Without Removing Siding

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.

Install new windows without removing siding.

Use a hammer or a drill to take out any nails or screws that are holding the window in place. Replacement windows fit into the existing opening and do not require removing any siding. 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. With window tape cover up all seams.

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. 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. 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.

Caulk any major voids. Installing siding once it s been cut to. 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. For the new windows they cut off the flange from the new window.

Sometimes there are little pieces of wood between the window and the wooden studs that hold the window tight. Insert replacement windows aren t the best option in my case due to the construction of the old aluminum window frames. If you find damaged or rotten wood remove it and cut new wood to replace it. Replacing your windows and siding concurrently allows your contractor to precisely set the capping around the window before they put the siding in place.

My question is how can i remove the old window without taking off the siding. 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. It s my understanding that new construction style windows can have the nailing fins removed and installed without removing the surrounding siding and j channel.
