My side door was installed incorrectly several years ago. Since then, I have had it repaired a couple of times, but with no real luck. There was a decent gap along the side letting in a lot of air. I called Door Doctor to come out and try to fix it. Mark came today. He was nice, timely, efficient, professional, and did a fantastic job. He fine tuned it several times to make sure it was just right. No gap! Very fair price. I would use them again and request Mark for door repairs. He was great.
