What We Do

Sliding glass doors often have weak factory latches that can be easily defeated. S.A.

We service sliding patio doors, glass pocket doors, and aluminum/vinyl slider doors. A properly secured sliding door should have both a primary keyed lock and a secondary security bar.

Frequently Asked Questions

How do I secure a sliding glass door?

Install a keyed lock, a Charley bar or security bar, and an anti-lift pin. This combination prevents the door from being forced open or lifted off the track.

How much does a sliding door lock cost?

Sliding door locks cost $50-$150 installed. Security bars cost $25-$75. A complete security upgrade runs $100-$250. Call (210) 348-3677.

Can sliding doors be burglarized?

Yes. Factory latches on sliding doors are often weak. Burglars can lift the door off the track or force the latch. Proper locks and anti-lift pins prevent this.

What is a Charley bar?

A Charley bar is a security bar placed in the sliding door track to prevent the door from being forced open. It’s an inexpensive but effective secondary lock.

Do you repair sliding door locks?

Yes. We repair and replace mortise locks, latch mechanisms, and keyed locks on sliding doors.
