I live in suburbs of Atlanta. We built a house in 1998. We have an ongoing problem with our backdoor rotting. Our back door faces the North and when it rains, the water runs down the door and ends up collecting at the base. Nearly every year I have to take a reciprocating saw, cut out the bottom of the T-Mull frame and replace it. Two problems here – one, it looks horrible and the wood rarely matches my door frame and two, I have to replace it EVERY year. I have four inch gutters above the door, however that help is minimal as the rain blows in sideways. Need some help!
