Sliding Door Track Repair
The surface everything else depends on
Once a roller collapses, it grinds metal. Grooves, burrs and flattened rails are the result, and they will destroy a new set of rollers in months. A damaged track can almost always be repaired or capped rather than replaced.

A worn track is why the second repair fails
People often tell us they already replaced the rollers and the door still drags. That is the classic symptom of an unrepaired track. New wheels cannot run true on a rail that has a groove worn into it, and within a few months they are flat as well.
The good news is that the track is repairable. A stainless steel cap installs over the damaged original and gives the rollers a hard, smooth surface to run on. It costs a small fraction of a new door frame and it outlasts the aluminium underneath it.
Where the sill itself is damaged, corroded or draining badly, that gets dealt with at the same time — because the sill is also what keeps rainwater out of your floor.
New rollers on an old damaged track is a repair with a short life expectancy.

Track and sill work
Repairing the running surface, and the sill that carries it.
Stainless steel track capping
A hard cap fitted over the worn original, giving new rollers a true surface and protecting the aluminium beneath.
Track straightening and repair
Bent, crushed and burred rails straightened and dressed back so the panel runs without snagging.
Full track and roller renewal
Done together, because one without the other rarely holds.
Sill drainage and weep clearing
Blocked weep channels push rainwater back into the room. Clearing and resealing the sill stops it.
Threshold and sill repair
Corroded and damaged sills repaired where the frame itself is still sound.
Anti-lift and guide adjustment
Guides and anti-lift blocks reset so the panel cannot ride up out of the track.
What damages tracks in California
Almost all track damage traces back to something abrasive, or something corrosive.
Grit as an abrasive
Dust blown in from inland and desert areas settles in the track and combines with lubricant to form a grinding paste. That paste does the damage long before the roller itself gives up.
Salt and corrosion
Coastal air pits and corrodes aluminium sills. A corroded rail is rough by definition, and rough rails destroy rollers however new they are.
Rain that has nowhere to go
California rain arrives in intense bursts. Patio sills are designed to drain, and when weep channels silt up, water sits in the track, accelerating corrosion and eventually finding its way inside.
Why capping beats replacing
There is rarely a reason to take a door frame out over a worn rail.
A fraction of the cost
Capping a track is a small job against replacing a frame, and it solves the same problem.
Harder than the original
Stainless outlasts the aluminium rail it covers, so the repair tends to outlive the door's first thirty years.
No structural work
No frame removal, no stucco or drywall disturbance, no repainting.
Same-visit completion
Most capping and track work is done while we are there.
Three steps, no runaround
Send a photo of the track
A close shot along the rail usually shows us straight away whether it can be capped.
We assess rail and sill
Including drainage, because a track that holds water will fail again.
We repair or cap it
Then fit rollers, level the panel and check the lock.

Track questions
Can a sliding door track really be repaired?
Yes. In the large majority of cases a stainless steel cap over the existing rail restores a true running surface. Full frame replacement is rarely warranted.
I already replaced the rollers and it still drags.
That is the textbook sign of a damaged track. The new wheels are running on a grooved rail and will wear out quickly unless the surface is put right.
Water pools in my door track when it rains.
The weep channels that drain the sill have blocked. Clearing them, and resealing the sill where needed, normally resolves it before it reaches your flooring.
Can you fix a bent track?
Often, yes. Bent and crushed rails can be straightened and dressed. If a section is beyond that, capping covers it.
How do I stop it happening again?
Vacuum the track a few times a year, use dry silicone rather than oil, and do not force a door that has started to drag.
Other repairs we handle
Doors and windows are all we do, so whatever has failed, it is probably on this list.
