• If you are going to need to have one door repaired, check the other doors in the house for minor problems that can be fixed at the same time.
• Make sure the doors fit with the layout of your house.
• They need to match your requirements and lifestyle i.e. a play area for children.
• If your entryways or other doors could use some reorganization, hire a carpenter or architect to design the ideal interior layout plan for you.
• Locks should all be in working order.
• Be aware of routine maintenance requirements, such as oiling of hinges, and repainting or staining.
