Window replacement is a straightforward process that begins with removing the old window. Start by carefully prying off the interior and exterior trim with a putty knife and pry bar, ensuring not to damage the surrounding wall. Once the trim is removed, use a utility knife to cut through any caulking or paint that may be sealing the window in place.
Then, remove the screws or nails holding the window frame to the wall. With the fasteners removed, gently push the window out from the inside. If the window is stuck, you may need to use a pry bar to carefully loosen it. After the window is removed, clean the opening thoroughly, removing any debris or old caulking to prepare for the new window installation.
Installing the new window involves setting it into the cleaned opening and ensuring it is level and plumb. Begin by applying a bead of silicone caulk to the exterior side of the window frame where it will meet the wall. Insert the new window into the opening, making sure it is centered and level. Use shims to adjust the window until it is perfectly aligned, then secure it in place with screws. Check the window’s operation to ensure it opens and closes smoothly. Once the window is secure, fill any gaps between the window frame and the wall with expanding foam insulation for a tight seal. Finally, reinstall the interior and exterior trim, and apply caulk around the edges to create a weatherproof seal. Allow the caulk to dry completely before painting or finishing the trim to complete the window replacement process.
