Door Latch and Knob Repair in Alhambra, CA

Short answer: When a door won't latch, we adjust the strike or replace the latch.

A door that drifts open, a knob that spins without opening anything, or a latch that sticks halfway is a small hardware fix. We realign the strike, tighten or replace knobs and levers, and swap worn latches so the door catches every time.

Quick answer

Doors that won’t latch need the strike lined up, the latch replaced, or the hinges tightened. We fix the cause, test that the door closes with a gentle push, and leave the hardware working smoothly.

In Alhambra homes

About 77 percent of Alhambra’s homes were built before 1980, according to a city housing report. In older houses doors have been painted repeatedly and frames have settled, so latches gradually stop lining up with their strikes.

Hinges first

A loose top hinge lets the door sag so the latch drops below the strike. Tightening it often fixes the latch.

Move the strike

Shifting the strike a little is cleaner than planing the door.

A door that won’t latch: the latch bolt misses the strike plate when the door or frame shifts.

Vintage hardware

Original knobs and mortise locks can often be cleaned and adjusted instead of replaced.

In older Alhambra houses this job often turns up next to door hinge repair, door repair and adjustment, lock and smart lock installation and closet door repair, so mention those when you text and we can price them together.

Door latch and knob repair questions from Alhambra homeowners

Why does my door not stay closed?

The latch misses the strike, usually from settling, paint or loose hinges.

Can you fix a doorknob that turns but doesn’t open the door?

Yes. The spindle or latch is worn and gets replaced.

Can you replace round knobs with levers?

Yes, on most doors.

How much does door latch repair cost?

It depends on the hardware. Text a photo for a free estimate.

What types of door latches are there?

Passage latches just hold the door closed. Privacy latches lock with a button. Keyed entry latches lock with a key. Each fits a standard bore, and we match the backset of your door.

Can you replace a door latch assembly?

Yes. We remove the old latch, check the backset, and install a matching latch. Then we adjust the strike so it catches.
