DIY expert Josh Temple shows how to take out an unwanted window and make the space part of the wall instead. Start by removing the window. Next, frame the opening with 2"x4" boards. Wrap the opening with a moisture barrier and seal the seams against weather with flashing. Skin the outer opening with a piece of material cut to the exact size of the hole. Inside, fill the wall with insulation, then cover the hole with a piece of material that matches the interior. Secure the material to the studs, then finish the interior and exterior with paint.
