Latch replacement

Help for doors that will not latch reliably.

We replaced a latch on Mud Road. A sticking or failed latch needs to be assessed alongside the strike and door alignment so the replacement suits the existing door.

A Schlage deadbolt, mortise cover plate and lever.

For a store in Stony Brook Village Center, we fitted a Schlage deadbolt, mortise cover plate and lever. The photograph shows the separate deadbolt above the lever and the rectangular plate covering the previous mortise preparation.

A door with existing mortise preparation needs careful hardware selection. The cover plate, lock positions and door condition all affect how replacement hardware can be fitted.

For similar work, send photos of both sides and the edge of the door. Tell us what hardware is currently fitted and how the entrance is used.
