Hinges, strike plates and locks: repairs that make a door secure and tight
Many security and draft problems are hardware problems, and the fixes are inexpensive when done correctly.
AHardware that wears out
- Hinges whose screw holes have stripped and let the door sag.
- Strike plates fastened with short screws into thin trim.
- Deadbolt latches that no longer line up with the strike.
- Weatherstripping that is flattened, torn or painted over.
- Door viewers and mail slots that leak air.
BCommon repairs
- Anchor the hingesLonger screws, usually into the framing behind the jamb, hold the door firmly.
- Reinforce the strikeA strike plate with long screws that reach the stud resists forced entry far better than one held to the trim.
- Re-bore or realign the latchIf the bolt does not align, the strike or the bore is adjusted.
- Replace weatherstrippingNew compression or magnetic stripping seals gaps around the door.
CPhiladelphia points
Vestibule doors
Many older rowhouses have an inner and outer door. Both should latch and seal, since the vestibule often sits between a heated space and the street.
Rentals and landlords
If you rent, ask the landlord before changing locks or hardware. Lock changes can affect emergency access and your lease.
Locksmith or door installer
A locksmith handles keys and cylinders. A door installer handles fit, frames and weatherstripping. Many problems need both, so say what you want done.

?Questions people ask
Will a longer screw really help security?
Yes. Short screws only grip the thin trim. Long screws into the framing make forcing the door open much harder.
Can I upgrade a lock myself?
Many people can, but make sure the new lock matches the door preparation. A repairer can bore or fill holes where needed.
What about fire doors in multi-unit buildings?
Doors that are part of a rated assembly must not be altered casually. Ask the property manager and city codes officials.
