I just put in a new door for our entryway. The old door was all wood,
weighed about 3,000 lbs and was just drafty, it was time for a new
So after all was said and done I put the new door in. Everything was
level. The bottom of the door was just a little off from touching the
sill and I could feel the cold air rushing in. So I decided to use the
screws that are on the adjustable sill to raise the sill so it would
create the proper seal.
I turned the 4 screws counter-clockwise to raise the sill but the sill
didn't budge. The directions said you'd only have to turn these screws
a half turn.
The last screw on the right of the door was VERY hard to turn.
Needless to say there is a large enough gap there that the freezing
cold air just blows in.
Of course the door was already secured to the opening. so taking the
door out is basically out of the question.
