How do you 'fill' the hole at the bottom of french doors?
I have french doors which were installed from my kitchen to the patio last fall. The left door is kept stationery and the right one opens inward -so far so good. However I just now noticed a huge space where the doors meet at the bottom - at least it's huge to me - and it's big enough for all kinds of creepy crawley things that could come in even a small snake not to mention losing A.C. in the summer and cold coming in in the winter as the doors face north. I went to H.D. where they were bought and was told the insulation is short by about an inch (or two) and that's just the way they're made! Went to Lowe's and was told the same thing. I'm really appalled. Please help. The man who installed them for me is retired and very ill so I don't really want to bother him with it but there's GOT to be a solution. Please. Thank you.
