How to fix
sliding door tracks
Sliding doors need to be maintained, otherwise they become
slide and can even jump off the tracks. The
wheels on sliding doors glide along a track, much like the
wheels of a train. The most important thing to remember is
to keep the track clean and free of dirt and dust that can
clog the wheels.
A good rule of thumb is to clean the tracks whenever you
clean your floors. Vacuuming usually works best. Remember
also to lubricate the tracks regularly. (There are dozens
of inexpensive industrial and household lubricants on the
market—ask your hardware salesperson.) A couple of times a
year, it’s also a good idea to clean the small drain holes
on the sides of the tracks with a brush and soapy water.
And every six months, it also pays to tighten the screws
on the track, since loose screws will make the door drag
and can also block the door’s path. If your door needs to
go higher or lower to run smoothly, adjust the screws on
the side of the door.
FIXING SLIDING DOOR TRACKS
If your sliding door is still not gliding easily and/or
closing snugly against the jamb, it’s likely the rollers
need more cleaning, or the track is bent. You might want
to take the door off and try a simple tune-up.
Glass sliding doors are usually heavy and awkward, so it’s
best to have someone help you when you take it off its
tracks. Worst-case scenario, trying to do it on your own
could result in the door falling and shattering. When you
do lay the door down, it’s a good idea to have some kind
of padding ready (old towels will do), to prevent
scratching or damage to the rubber seals.
After cleaning tracks and rollers, you should oil only the
rollers, not the tracks themselves because that can
attract even more dirt.
How to fix sliding door tracks:
1. With one person on either side of the door, lift it up
off its tracks and pull it away at the bottom. Then lower
it from the upper track and place it gently on the floor.
Lubricate and clean the rollers.
2. If an outside track is bent, place a block of wood on
the track. Then take the hammer and bang the wood to
straighten out the bend. Don’t use your hammer directly on
the track because that can cause more damage.
3. Once the tracks are straightened, replace the door.
Slide the door shut, checking for an even gap between the
door and the jamb as you do so.
4. Adjust the screws on the side of the door if needed to
raise the door up or lower it down.
