Jeez, on rainy/snowing and windy days, I get some seepage under the door. Not a lot, mind you, but a little.
DUmmies--garage doors DO have adjustments on them. Also, you can buy insulating strips/bumpers for the doors themselves.
Now I'll just sit back and listen to you blame the Rethuglican/KKK/fundies for installing your door incorrectly.
