If the existing door on your home is a standard size with stock casing on the door frame, removing and replacing both the door and frame with a prehung wood, fiberglass, or steel door unit isn’t that difficult.
When to Replace an Entry Door
An existing exterior door on your house may need to be replaced if:
- The wood has begun to deteriorate or rot.
- Joints on the door are coming loose.
- The exterior of the door will not hold a finish.
- Weather stripping and threshold don’t provide a good seal.
- The door has uninsulated, single pane glass.
- A different style or design of door is desired.
If the existing entry door on your house doesn’t have any of the problems listed above, you may want to try to refinish and refurbish it instead, which can be a lot less work than replacing the entire door unit.
While you can replace just the door, rather than the entire door unit, it’s easier and provides a better seal to replace the entire unit. However, if the house is older, and the frame on the existing door isn’t made from stock materials, it may be better to replace just the door, rather than the entire frame.
