How to Replace a Window Casement Latch


Take the existing casement window latch and see if you can shake it. If the latch is secure, you're in luck! This latch will most likely screw out easily and the wood is firm enough to take the new screws without a problem. If the latch is loose then you might be in for a more extensive repair job.


For the most part replacing a window latch is reasonably simple; unscrew the old latch and install the new one. But there are a few minor steps that need to be followed to get it all lined up and working properly. If your old latch was worn out or broken, you may not need to take any extra steps for the install job. However, if it didn’t lock because it was misaligned than you’ll need to make a few additional adjustments.


For best results installing a lock into bare wood will get everything working smoothly. Odds are that your new lock will be a different shape to your older one. After you remove the old lock, put your new casement window latch up to the window, then trace around it with a pencil and mark the screw holes. Sand or scrape away any paint in this section until you reach bare wood. Drill out the screw holes and install the lock (if you're going to paint the window soon after, you can put some painters tape around the latch before screwing it down).


With the latch installed, next you’ll need to install the keeper. Some latch kits will include a template, but if you don’t have one or it was lost you can still install the keeper without too much trouble. Close the window and hold the keeper in place and lock the window. The latch should slide smoothly into place, and the keeper should be hard against the latch. Mark the screw holes and drill them out, then screw the keeper in place (some keepers allow for adjustment after the screw holes have been drilled).


Test the window, and check that the casement window latch is working properly. Ideally everything should be perfect. Now all you’ll need to do is paint around the lock and the install will be seamless!
