Lock Repair in Houston, TX

How Houston weather wears on locks

• Flooding. Hurricane Harvey stalled near Houston in 2017, and rainfall passed 30 inches in many locations. Water that reaches a lock leaves silt in the cylinder and rust on springs and latch parts, so a lock that sat in floodwater should be cleaned or replaced.
• Swollen doors. A door or frame that took on water can bind, so the bolt drags against the strike and the key has to force it. Sometimes the fix is adjusting the strike rather than touching the lock.
• Freezes. Hard freezes do reach the city, as in February 2021. Thaw a frozen lock with de-icer, not hot water, which can run inside and refreeze.

Keeping old hardware working in Old Sixth Ward

Old Sixth Ward became the first Houston neighborhood on the National Register of Historic Places in 1978. Its surviving houses go back as far as 1854, and doors of that age may carry original hardware that is hard to match, so repairing the existing lock often keeps more of the house intact than replacing it.

Under Chapter 33, Article VII of the Houston Code of Ordinances, city guidance for historic districts treats repair differently from replacement. Work that corrects or prevents deterioration while leaving an exterior feature's design, character, texture and material unchanged does not need a Certificate of Appropriateness, although other permits may apply. Swapping out historic material falls outside that exemption. This is general information, not legal advice.

Simple upkeep

1. Lock and unlock doors you rarely use, such as a back or side door, every few weeks.
2. Put a dry lubricant such as graphite in the keyway; household oil holds dust and grit.
3. Tighten loose hinge and strike screws so the door does not sag.
4. After a storm puts water against a door, work the lock, and have it checked if it feels rough.

Describing the problem

Say which lock is failing and how: the key turns hard, the bolt does not reach the strike, or the knob is loose. Mention any flood exposure, the age of the house if you know it, and whether it sits in a historic district. The lock repair page covers the service, and lock replacement applies if a cylinder is past saving. Historic-district notes are on the Houston page.
