Frequently Asked Questions
What is a solid core interior door?
A solid core door features a smooth wood veneer or primed hardboard skin built over a dense wood composite or MDF interior. It provides the heavy feel, structural stability, and soundproofing of solid wood at a much better value.
Are solid core doors good for soundproofing?
Yes. Their dense composite interior dramatically cuts down noise transfer, making them the top choice for home offices, bedrooms, and media rooms.
Should I buy a door slab or a prehung door?
- Door Slab: Just the door panel itself. Best if your existing frame, jambs, and hinges are in good shape and you are doing a direct replacement.
- Prehung Door: Comes pre-mounted in a matching frame with hinges attached. Best for new builds, full renovations, or replacing damaged frames.
Do these doors come ready to paint?
Yes. Our primed solid core doors feature a smooth, factory-prepared surface ready for you to paint and match your interior trim.
