Replacing window hardware involves removing old hardware from the window and affixing new hardware to the window. To complete this task, obtain new hardware with a size similar to the old hardware, and collect necessary tools including a screwdriver, wood screws and a utility knife. A stepladder is handy when dealing with a tilt or transom window. To avoid making any errors, hire the services of an expert when replacing mechanical window hardware.
Removing the old hardware involves using the utility knife to cut off paint wherever a hardware piece is attached to the window, in order to access the screws that keep the piece attached. Repeating the process for the remaining pieces readies all the screws for removal. Turn the screws counter-clockwise with the screwdriver before removing them. After removing all the screws, detach all the hardware pieces from the window, one at a time, and set them aside.
Next, take one of the new hardware pieces, set it in its appropriate place on the window, and secure it in place with the screws, taking care not to overtighten the screws. Repeat the process for the remaining pieces. Latching the window to check the new hardware for any installation defects, and then fixing them as needed, completes the process.
