Inspection checklist
- Describe closing and locking separately
- Inspect the mating components
- Confirm a complete repair
A sliding door may travel normally yet fail to lock. The latch and keeper need to meet correctly, which also depends on the position of the moving panel.
Use these points to understand the opening or system before choosing parts or approving a larger replacement.
Call or send photos with your ZIP code. We confirm availability and arrange an inspection when needed. We explain the recommended work and price before you approve the job.
Explain whether the panel reaches the jamb, bounces back, needs lifting or closes fully with a handle that will not turn. The difference helps separate travel, alignment and locking faults.
The lock body, handle, keeper and panel support should be considered together. A replacement handle may not include the part causing the problem. Hardware dimensions and the door model help establish compatibility.
Ask whether the scope addresses the underlying alignment and tests locking after normal sliding operation. A damaged track or roller can change the way the latch meets its keeper. Avoid forcing a handle or ordering a generic lock before the assembly is identified.
No. The internal lock, keeper or panel position may be responsible even when the handle is the part you touch.
That can indicate an alignment or support issue, but the door needs inspection to establish the actual cause.
Send the full panel, handle, latch edge, keeper and visible manufacturer information.
Send photos and your ZIP code, or call 770 Doors & Windows directly.
A sliding door can roll normally but fail to lock because of a worn latch, damaged handle or misaligned keeper. We check both panel alignment and the locking hardware before selecting a compatible replacement.
Coverage includes Bronx, Brooklyn, Long Island, Manhattan, Queens, Staten Island. These areas describe service coverage, not branch offices or completed jobs. Send the property address or ZIP so we can confirm availability and the work required.
