Stuart Sliding Door Repair re-squares sliding panels that have dropped or racked, which fixes sticking, uneven gaps and locks that no longer engage.
Alignment is the cheapest sliding door service there is, and it is often all a difficult door actually needs.
A sliding panel has to sit square in its opening for anything else to work. The lock engages by a few millimetres, the weatherstrip seals by contact, and the rollers only track properly when the panel is plumb.
When any of that drifts, the symptoms look like several different faults at once. They are usually one fault: the door is no longer square.

Why Sliding Doors Go Out of Square
The most common reason is simply that the rollers have worn unevenly. Each end of the panel has its own adjustment, and each carries its own load, so when one wheel degrades faster than the other the panel tips slightly. The gap along the head track then tapers from one end to the other.
The second reason is the building. Florida slab-on-grade construction moves, and a large opening in a wall that has settled even slightly will rack the frame out of square. In that case the panel is fine and the opening is not.
The third is previous work. A door that has been taken out and put back without resetting both ends, or a frame that has been shimmed in a hurry, comes back racked. We see this a lot on doors that have had one previous repair.
Signs Your Door Needs Aligning
- The gap at the top of the panel is wider at one end. The clearest single indicator. Sight along the head track from inside.
- The door catches at one point in its travel and runs freely elsewhere. The panel is out of plumb and touching at that point.
- The lock only engages if you lift or lean on the door. The hook is missing the keeper because the panel has dropped.
- You can feel a draught along one edge with the door closed. The weatherstrip is only contacting on part of its length.
- The panel edge is not parallel with the jamb. Look at the vertical gap top to bottom - it should be constant.
- The door was fine until recently and nothing was replaced. Sudden onset without new parts usually means the panel shifted, not that anything broke.
How We Square a Sliding Door
Measurement first. We check the head reveal at both ends, the vertical gap at the lock stile from top to bottom, and whether the panel is plumb. Those three readings identify whether the fault is roller height, frame racking, or both.
If it is height, both adjustment screws get set - not just the low end. Adjusting only the dropped side is how doors end up riding on one wheel, which is what caused the problem the first time. The aim is even load and an even reveal.
If the frame is racked, screws alone will not fix it and we say so. That becomes a shimming or reset job, and it costs more, and there is no honest way to make it a fifteen-minute adjustment. What we will not do is wind the rollers to their limit, call it done, and let you find out in three months.
Settlement and Seasonal Movement in Martin County
Sandy soils and a high water table are normal across this part of the Treasure Coast, and both contribute to slab movement. Large sliding openings are the first place that movement shows, because they are the widest unsupported spans in most walls.
Seasonal swing matters too. The humidity difference between August and January is substantial here, and timber framing around an opening moves with it. Doors that stick only in late summer are usually telling you that, rather than reporting a broken part.
That is why we build a follow-up adjustment into alignment work. A door set square in one season can want a small tweak in another, and that is a normal characteristic of the building rather than a failed repair.
Alignment vs. Roller Replacement
| Repair | Replace | |
|---|---|---|
| Typical cost | Alignment: around a hundred to two hundred | Rollers: a few hundred per panel |
| Time on site | Often under an hour | Usually under two hours |
| Fixes uneven gaps | Yes | Only if worn rollers caused them |
| Fixes grinding or rumbling | No | Yes, that is bearing failure |
| Right call when | The door moves but sits crooked | The door is hard to move at all |
| Wrong call when | The wheels have seized | The frame is racked, not the wheels |
Frequently Asked Questions
A straightforward adjustment is the least expensive service on this list. It rises if the rollers have to be reset at the same time, and considerably more if the frame itself has racked and needs shimming.
Yes. There is an adjustment screw at each end of the bottom rail, usually behind a small plug. The mistake to avoid is turning only the low end - set both so the load is even, or you will wear one roller out again.
Check whether the frame itself is square before blaming the panel. If the frame is out of square, adjusting the panel is treating a symptom, and the door will drift again.
Seasonal movement. The humidity swing here is large enough to move framing around an opening, and a door set with tight clearances in winter can bind in August. It is normal, and it is why we include a follow-up adjustment.
Frequently, yes. A lock that stopped engaging without anything breaking is usually a lock whose keeper the hook can no longer reach, and restoring the panel height puts them back in line.
