Bilco Door Replacement/Repair?

[Joe P.]

Hi all - we just got a ton of rain and getting water in my duplex basement. My tenant says a large majority is coming through the flat Bilco doors adjacent to the building. As you look at the doors from the basement there is daylight where the doors open and along their seams (hinges). And apparently, its enough to cause quite a bit of water in the basement.

I called a "Bilco door specialist" -- those exist, apparently -- and they're saying I need a custom door replacement and the cost is $6500. Of course it is.

Has anyone had any experience with possibly repairing or replacing those doors? Don't want water coming in, but I don't want to pay $6500 to solve the problem, either.
