Check the opening before the product
External doors have to deal with the transition between inside and outside. Measure the opening, check the threshold and understand how the existing frame meets the wall and floor before choosing the replacement.

Frame condition and depth

Look for the cause of an existing problem
A draught, leak or door that will not close may come from alignment, a damaged seal, threshold movement or the frame rather than the door leaf itself. Replacing the correct part starts with identifying the cause.
Photos that help
Send one photo from inside, one from outside, a close view of the threshold and any damaged or poorly fitting area. That gives a much better starting point than a single front-on image.
