Like Steve said, this can be about as advanced as it gets and I find a lot of carpenters don't even know all of the ins and outs of installing and/or tweaking a door. Steve had some good suggestions, but unless we see it, we are really only guessing. "tight" can mean a number of things, maybe try sending us a much more detailed desription. Don' listen to the idiot below, he has nothing to contribute and is basically trying to wreck this board for everyone else. If he knew anything about doors maybe he could actually try to help someone instead of repeatedly proving that he should be on medication.
