A draft near an exterior door can come from gaps, worn seals or an entrance that no longer aligns correctly. The first step is to identify where air appears to enter. The visible gap may be related to the door position or surrounding condition, so adding a seal without reviewing the opening may not address the full problem.
Describe when the draft is most noticeable and whether the door also sticks or fails to latch. Changes in operation can help explain why a seal is no longer making consistent contact. The threshold, frame and existing weatherproofing should be considered together. Photos of the full entrance are more helpful than a close-up of only one corner.
A repair should balance weather resistance with normal operation. The door should still close and lock without excessive effort after the work. Ask which components are included in the proposed service and whether damage around the opening needs separate attention. Problems beyond the door assembly may require a different scope from ordinary hardware or seal replacement.
