Hushed hinges
Hinges have a bad reputation when it comes to noisy doors. We can thank scary movies for that. But fixing a squeaky hinge doesn’t have to be a nightmare. You can use WD-40 again, just like on your latch, or try other household items to quiet a squeaky hinge.
If the creaking is due to door misalignment – you might also notice that the door doesn’t close all the way or sticks when you try to open it – try tightening the screws on the hinges. Tighten them a little bit at a time and test your progress with a level as you go.
A slamming door could mean that the hinges are worn beyond repair. Lubricating them and tightening the screws won’t make a difference. In this case, you’ll need to replace the hinges. It’s an easier DIY job than you might think since there’s no need to remove the door. Simply replace one hinge at a time, starting at the top of the door frame, using a level to check the door alignment after you install each one.
