Looking for someone asap who has worked on this problem and can either fix it until spring or fix permanenately. My furnace is running continually due to the smaller gaps causing air, wind etc. between the door and door frame. There are 2 doors involved with gaps but right at this moment I only care about the back (north) door. I don't want new doors as these doors are only 4 years old. Please help!! You can give me your price after you assess. Thank you.
