Spent $548.00 for a new steel door from the Orange box store. Problem is , the door is hard to open. Had the Contractor out to see if he could fix it and he tightened down the threshold, but it still pulls hard to open. I lightly sanded down the brown rubber threshold. ( That was brand new !) and it closes better , but to open it, I really have to pull on the knob. I checked on all sides, and the door and frame are square. Only thing I can think of is that the rubber piece on the bottom of the door might be rubbing on the threshold. The Contractor said that ALL DOORS ARE LIKE THIS NOW!!
What else might it be ? I don't want to sand too much of the rubber threshold down, don't want air leaks.
