Why won't my cabinet drawer slide smoothly, or why is the door sagging?
What’s likely going on
Drawer slides wear out or come loose from repeated use, and cabinet hinges can loosen the same way a door hinge does — small, ordinary wear that adds up over years of daily use.
Is this a DIY job or worth calling someone?
Often a matter of tightening loose screws or replacing an inexpensive slide/hinge — a reasonable project for anyone comfortable with basic tools. If the cabinet frame itself has warped or pulled away from the wall, that's a bigger fix worth having someone assess.
Not sure, or ready to have someone take care of it?
