Install New Windows Without Removing Siding

Caulk any major voids.

Install new windows without removing siding.

Sometimes there are little pieces of wood between the window and the wooden studs that hold the window tight. 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. For the new windows they cut off the flange from the new window. Attach new pieces with screws and wood glue.

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. 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. Use a hammer or a drill to take out any nails or screws that are holding the window in place. With window tape cover up all seams.

To the edge of the window to about 1 past the outside seam. If you find damaged or rotten wood remove it and cut new wood to replace it. My question is how can i remove the old window without taking off the siding. 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.

Replacing your windows and siding concurrently allows your contractor to precisely set the capping around the window before they put the siding in place. 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. 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. If you want to fully replace with new construction windows you will have to deal with the siding.

Replacement windows fit into the existing opening and do not require removing any 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. Insert replacement windows aren t the best option in my case due to the construction of the old aluminum window frames.
