What the Noise Your Door Makes Is Telling You
Sliding doors are fairly good at describing their own problems. Here is how to translate.
Grinding or crunching
Grit in the track, and the rollers are dragging through it.
Vacuum and scrub the track, then use silicone spray. If the grinding continues on a clean track, the rollers have worn flat and are riding on their housings.
Squealing
Dry rollers. Silicone spray usually sorts it in seconds.
If it comes straight back, the bearings have gone and the rollers need replacing.
Heavy the whole way
Worn rollers, or rollers adjusted too low so the panel is dragging.
Try cleaning and lubricating first. If nothing changes, it is a parts job.
Sticks in one spot only
Something is wrong at that point specifically. Usually a dent in the track, or debris packed into one section.
Look along the track at eye level. A flattened section is visible once you know to look for it.
Rattles when closed
The rollers are set too high, or the weatherstripping has flattened so nothing is holding the panel steady. Often both.
Will not lock unless you lift or lean it
Alignment. The door is not sitting where the lock expects it to.
Worth fixing rather than living with, because a door in this state often ends up not actually locked.
Bangs at the end of its travel
The bumper has perished or fallen out. Small part, easy fix, saves the frame taking the impact every time.
Draught along the edge
Flattened or cracked weatherstripping. Cheap to replace, and it makes a real difference to the power bill through a Florida summer.
Where to start
Clean and lubricate first, whatever the symptom. It is free, it takes twenty minutes, and it fixes a surprising share of these outright.
