The quick version
I fix latches that won’t catch by aligning the strike, tightening hinges, or replacing the latch. Older San Gabriel homes may have mortise locks, which I can service too.
What I need in your text
- The latch on the door edge

- The gap on the latch side
- The handle, inside and out
- A clip of the latch missing the strike
What I repair

- Glass and vintage knobs reattached
- Levers fitted for easier use

Latches on older San Gabriel doors
With 52.3 percent of homes over 60 years old, many San Gabriel houses still have original doors with mortise locks or glass knobs. These often just need cleaning, a new spring or a set screw, not replacement.
Where a house has settled, I move the strike rather than planing the door.
How I repair it
Diagnose
Check hinges, latch and strike.


Adjust
Tighten hinges and move the strike.

Repair or replace
Service or swap the latch and knob.
Test
Close it until it catches every time.
Bigger door problems
A warped slab or a frame far out of square may need carpentry.

Latch questions
Why won’t my old door latch?
Settling or paint has moved things out of line. Moving the strike usually fixes it.
Can you fix a glass doorknob that spins?
Usually; the set screw or spindle needs work.
Can mortise locks be repaired?
Often, by cleaning or replacing springs and parts.
How much does door latch repair cost?
It depends on the hardware. Text a photo for a free estimate.
Can you swap knobs for levers?
Yes, on most doors.
Why does my latch stick?
Old paint, dirt or a tired spring.
Can you fix an old mortise latch?
Yes. Mortise locks have a box inside the door. I clean, lubricate or replace the parts, or the whole mortise body if needed.
Where can I find door latch parts?
Most latches are standard, but older ones may not be. I match parts by size and backset.
