Doors & hardware · A short practical guide
Latch will not retract: handle or internal mechanism
Latch will not retract: handle or internal mechanism. Sticking can come from door alignment, the handle spring or the latch case.

What to check
Sticking can come from door alignment, the handle spring or the latch case. The exact item, substrate and room conditions should be assessed together. A universal fixing or a single photo cannot confirm suitability.
Preparation and next steps
Show the door edge and both handles; note whether it sticks while open and avoid slamming it. Confirm the substrate, supplied parts, access and scope before work begins.
Photos + dimensions + city + preferred time.
Understanding the prices
These are labour estimates, not a final quotation. Fixings, materials, removal, difficult access, a helper and additional jobs are agreed separately. Confirm the minimum visit charge and total before booking.
