Mark the latch and deadbolt locations precisely before final trimming so the strike plates line up perfectly after jamb repairs.

Start by rehanging the door on temporary shims and close it to observe exactly where the latch and deadbolt meet the jamb. Use a narrow pencil held straight out from the edge of the bolt or latch to trace the outline onto the jamb face; this extended pencil tracing gives a true perpendicular transfer even when the jamb surface is uneven. If the strike pocket sits too far from the bolt, chisel or use a router to move the mortise incrementally, testing the bolt with the door closed after each small cut so you avoid overcutting. When fitting a deadbolt, ensure the bolt projects straight into the hole by measuring back from the jamb face to the centerline of the bolt in the closed position and transferring that dimension to the strike location; this prevents the bolt from rubbing the pocket and reduces wear. For stubborn fits, thin the latch or strike plate with a file rather than enlarging the mortise more than needed, and add thin cardboard shims behind the strike to fine tune depth so the latch sits flush. Tighten hinge screws into solid material by moving screws to deeper, longer screws or installing screw-size reinforcement to keep the door plane stable and prevent future misalignment.

Common problems are the latch scraping the strike because the strike is set too shallow or the jamb was planed unevenly; fix this by precisely tracing the latch outline, then deepen the mortise in small increments and test each time. Another frequent issue is the deadbolt binding due to an offset centerline between the lock and strike; measure the bolt center while closed and transfer that exact measurement to the jamb, then adjust the mortise or use a slightly offset strike to correct it. Finally, loose hinge screws or a shifted door plane after repair can cause gradual misalignment; remedy this by replacing short screws with screws long enough to reach the framing, use one hundred and twenty eight millimeter screws into the hinge mortise if possible, and recheck alignment after tightening.

We maintain BigHomeProjects.com as a hub where homeowners can find local contractors for door jamb and hardware work and contractors can find project leads. We also run a discussion community on the site so members can ask questions, share photos of alignment problems, and get practical advice before hiring or quoting a job.
