Are your doors sticking and binding? If you are tired of pulling and tugging, you are probably ready to start planing and sanding. Knowing why doors stick can help solve the problem quickly and easily. Doors often bind because the opening somehow shifted, moving it "out of square." Usually, the cause is moisture -- sometimes in the ground, under your house -- rather than in the door frame itself. The wet ground expands, and part of the foundation moves up or down, creating an uneven floor. Thus, frames shift and doors bind. Often you can skip planing and sanding by simply adjusting the door hinges. Pull out the hinge pins one at a time, and bend the rungs the opposite of the way you want the door to move. A little trial and error, and you will soon get the idea. And that's the On The House tip for today.
