Buying Guide: Key Considerations For Interior Door Casing
- Material choice: Solid pine yields natural warmth and durability; polyester/polymer options are maintenance-free and moisture resistant but may lack true wood grain.
- Finish and prefinishing: Prefinished options save time; primed frames require painting to match room decor.
- Frame dimensions: Compare inner and outer frame sizes to your door opening; misfits require trimming or may leave gaps.
- Installation approach: Complete retrofit kits with lintels streamline renovations; simple jamb-only sets suit quick upgrades.
- Moisture exposure: For humid or wet areas, moisture-resistant materials help prevent warping and rot.
