Replacement Door Checklist

Look for these characteristics when recommending a replacement entry door:

  • The door frame is rotting, deteriorating or cracked.
  • There are air gaps letting energy escape.
  • The door does not open or close properly.
  • The door is warped, cracked or dented.
  • The subfloor under the door is rotting or deteriorating.
  • The glass in the door is collecting moisture.
  • The door is not sealing properly and water is entering the home.

How to Measure for a Door

  1. Door Width
  2. Door Height
  3. Door Depth

If you could peel back the siding, measuring would be easy. Our goal is to find the dimensions of the rough opening, which is jack stud to jack stud, header to floor, and wall depth.
