Sliding Door Track Repair New rollers won’t fix a chewed-up track.
The bottom track is the rail your door rides on. When it’s dented or packed with sand, even brand-new rollers bump and drag. We clean and straighten it. If the rail is worn past saving, a stainless steel cap goes over it.

Signs it’s the track
Get down at floor level with a flashlight and look along the raised rail. The track usually tells on itself.

What we do
What a track repair involves
-
Step 1: Clean it out
We vacuum out the sand and scrape the packed grit from the corners and from under the edges of the rail.
-
Step 2: Clear the weep holes
The small drain slots in the sill let rainwater out. We clear them so water drains instead of rising.
-
Step 3: Straighten and smooth
Dents in the rail get worked back into shape, and burrs and rough spots are filed smooth so the wheels roll clean.
-
Step 4: Cap it if it’s worn out
If the rail is worn flat or badly pitted, a stainless steel track cap fits over it and gives the rollers a new surface.
-
Step 5: Rollers and height
A damaged track usually means worn rollers. We replace them when they need it and set the panel height to match the repaired rail.
Rollers and track wear each other out
Think of them as a pair. A roller with a rusted bearing stops turning and skids, and a skidding wheel gouges the aluminum rail. Then the gouges chip and flatten the next set of wheels. Fix only one and the other starts the cycle again.
So a track repair comes with a look at the rollers, and a roller job comes with a look at the track. You get one exact price for what the door actually needs.
The weep holes nobody knows about
Most sliding door sills have small drain slots, called weep holes, on the outside face. The track is built to catch some water in a heavy rain and let it drain out through them. When sand, leaves or dead bugs block them, the water has nowhere to go but up and over the inside edge. Clearing them is part of every track repair we do.
Between visits: vacuum the track, then run a pipe cleaner through each weep hole. Skip grease and oil on the rail. They turn sand into grinding paste.
What we don’t do
We don’t replace glass or install new doors. We fix the one you have.
The track is part of the door frame, so replacing it outright means pulling the frame out of the wall. That’s installation work, and we don’t do it. Cleaning, straightening and capping keep the frame where it is.

FAQ
Track repair: straight answers
How much does track repair cost?
Every door is different, so we don’t guess over the phone. A specialist looks at your door and gives you an exact price, free, before any work starts.
No quotes over the phone, by text or by photo. Several doors? Ask about multi-door savings.
Can a bent sliding door track be fixed?
Usually. Dents and bends in the raised rail can often be worked back into shape. If the rail is worn flat or badly pitted, a stainless steel cap over it is the usual fix. Replacing the whole track means pulling the frame out of the wall. That’s installation work, and we don’t do it. If a repair or a cap can’t save it, we’ll tell you.
Why does my track fill with water when it rains?
Some water in the track during a hard, wind-driven rain is normal. It should drain out through the weep holes at the front of the sill once the rain eases. If it sits there or spills inside, the weep holes are probably blocked, or the seals at the bottom of the panel are worn.
What should I use to clean my track?
A vacuum with a crevice tool, then a damp cloth. For stubborn grit, a stiff nylon brush. Keep grease and oily sprays off the rail, because they hold on to sand. A light silicone spray on a clean rail is fine.
Is track repair the same as a track cap?
A cap is one kind of track repair. If the rail is sound, cleaning and straightening is enough. If the running surface itself is worn out, a cap gives the rollers a new one. More on stainless track caps.
