I have an original 100 year old exterior door that was recently restored. It is beautiful and I'm trying to avoid drilling or screwing things into it as much as possible. Unfortunately, there is a little over an 1 inch gap between the door bottom and the threshold (Threshold is made out of concrete) and it has become a problem during the winter with the cold air blowing in.
I went to Home Depot to find a door sweep, but all of them are too short for my door that is 37.5 inchs in width. Also, I can't find a product that allows you to screw the door sweep in once and replace the rubber sweep part when it wears out. Home Depot sold a U shaped door sweep where you can replace the rubber part, but you'll need to unscrew everything, and over time, the screw holes will wear out.
Do you know of a product that I'm looking for?
