i have a solid wood door on a 1927 tudor cottage that is warped. the upper corner pulls in about 1/4 to 1/2" out of plum. needless to say it's a huge heat loss as the cold air just blows in the gap.
Is there a way i can get the door back into plum? i believe i remember reading about a method of screwing a long board to the outer side with a block in the middle to pull the door back to straight.
any help is appreciated.
