yes michelle....it seems that the opening is too wide....we have (2) two-car garages attached to our house....the opening is 18' 3 1/2" wide on each one....the doors are 18', there is a 2 x 6 on each side, cut at a 45 degree angle at the bottom, and then a rubber seal on each side of the door.......when the door is closed,I dont see any daylight at all coming through the door area!.....

By the way, since you have a independent inspector checking these things, are you getting close to moving in?....
Getting excited??
