Buying Guide: Key Purchase Considerations for Interior Doors In Old Houses
- Preserve historic style: Choose knobs, mortise hardware, and finishes (antique brass, matte black) that echo period details while providing modern reliability.
- Door type and thickness: Verify whether you need a mortise lock, privacy hardware, or a simple passage knob, and confirm door thickness (commonly 1-3/8″ to 1-3/4″) for proper fit.
- Old-door compatibility: Mortise and crystal knob options can suit vintage mortise doors, but verify spindle sizes and sleeve requirements for a secure fit.
- Ease of installation: Slab doors offer a quick refresh; hardware sets may require precise alignment with existing door frames and latches.
- Repair vs. replacement: For heavily worn doors with warped frames, consider lightweight slabs or complete hardware refresh to avoid extensive carpentry.
- Finish and color coordination: Match finishes to existing hardware and trim to maintain a cohesive historic look across rooms.
- Durability and maintenance: Zinc alloy and brass finishes balance longevity with the aged appearance that complements old houses.
