Alignment, Leveling & Adjustment
Doors that drag on one side, meet crooked, leak at the corner or will not latch — the geometry fix underneath half of all slider problems.
A sliding panel is a big, heavy rectangle that has to stay perfectly square in its frame while riding on two small adjustable rollers — and everything conspires against it. Rollers wear at different rates. Houses settle, especially on Florida's sandy soils and around pool decks. A panel that was true in 2015 sits a quarter-inch low on the latch side today, and the symptoms read like five different problems: dragging at one corner, a lock that will not engage, a gap at the top of the meeting stile, a door that drifts open or closed on its own. Alignment service is the systematic fix: rollers adjusted (or replaced where worn), panel leveled and squared to the jamb, the interlock meeting evenly, and the lock and keeper brought back into true. It is the least glamorous service we offer and the one that quietly fixes the most doors.

Alignment, Leveling & Adjustment Questions
Is my door out of alignment, or are the rollers just worn?
Often both, in sequence: worn rollers cause the misalignment. We inspect the rollers first — adjusting a door on flat-spotted rollers is geometry on a broken foundation. If the rollers are sound, adjustment alone is the fix, and we will tell you that instead of selling parts.
Can a house really settle enough to affect a sliding door?
In Florida, absolutely — sandy soils, water table shifts and pool-deck movement all move openings by the few millimeters a sliding door cares about. The door does not need the house to be perfect; it needs to be adjusted to the house as it stands today.
My door rolls toward open on its own. Is that alignment?
Yes — the track or the panel is fractionally out of level, and gravity is doing the rest. It is adjustable in most cases, and it matters beyond annoyance: a door that drifts does not stay latched, and a door that does not latch is not locked.
How often does a sliding door need adjustment?
There is no fixed interval — adjustment is an as-needed service, typically after roller work, after settling events, or when symptoms appear. A door that is getting heavier on one side is asking early; answering early is cheap.
