To inspect locks, hinges and door hardware:

2. Tighten loose screws in hinges.

3. Re-hang doors if they have begun to sag or stick.

4. Check that the door closer valve (on storm or screen doors) is set to allow a smooth and gentle close.

To lubricate locks and hinges:

1. Locks should be lubricated with special graphite designed for locks.

2. Hinges should be lubricated with penetrating oil.  If the hinges are rusty:  remove the hinge pin, clean with steel wool, and coat both with protective grease.  Wipe up any excess grease or oil.
