When the door is hard to slide
Rollers carry the full weight of the panel. When their wheels wear flat, crack, or seize, the door starts to grind, jump, or need two hands to open. Sand and salt air accelerate that wear on doors facing the beach. Replacing the rollers with a set that fits the door’s housing and weight is often what restores smooth travel.
If the rollers are healthy, the drag can come from the track itself: a dented rail, a raised spot, or debris packed into the channel.
Track damage, repair, and snap tracks
Track rails can bend from heavy panels, impacts, or years of a failed roller grinding in one spot. Depending on the damage, a rail may be repaired, the track section replaced, or a compatible snap track installed. A snap track is a cover that fits over a worn rail to give the rollers a smooth surface again. It works where the underlying track is still sound; it is not a fix for a sill that is structurally damaged.
Handles, locks, and alignment
Balcony doors get used constantly, and handles and latches wear out. We replace broken handles and locks with compatible hardware and then check how the panel meets the frame. Adjusting roller height and alignment lets the latch engage cleanly and helps the door seal against the jamb when it’s closed.
- Lock no longer catches, or only catches when you lift the door
- Handle loose, cracked, or spinning freely
- Visible gap at the top or side when the door is closed
Regular and impact systems
Impact sliding doors use laminated glass and heavier frames, so their rollers and hardware have to be rated for the weight. We identify the door system before recommending parts. Replacing worn hardware is maintenance; it does not change a door’s impact rating.
How we assess your door
Hardware repair can often avoid full replacement, but only an inspection shows whether the frame and panel are worth keeping.
Check movement and fit
We slide, lift, and lock the panel to find where it binds or misaligns.
Inspect the components
Rollers, track rails, handle, and lock are checked against the door system.
Explain the options
You get a clear recommendation, from adjustment to parts replacement, before work starts.
Calling about a condo balcony door?
It helps to tell us the building, the floor, whether the door is regular or impact, and a short description or photo of the problem. If your building requires contractors to check in with management or reserve a service elevator, let us know so the visit can be arranged around those requirements.
Sliding Door Repair questions
Can you fix a sliding door that won’t lock?
Often, yes. Sometimes the lock itself has failed; other times the panel has dropped and the latch no longer lines up. We check both and replace or adjust what’s needed.
Do I need a new door if the track is damaged?
Not necessarily. Depending on the damage, the rail can be repaired, a track section replaced, or a compatible snap track installed over a sound track. Severe structural damage may call for more.
Do you work on impact sliding doors?
Yes. Impact panels are heavier, so we match rollers and hardware to the specific system rather than using generic parts.
