You may have been dealing with that sagging door for years before deciding to do something about it. The good news, though, is that fixing Diamond doors is easy, fast, and inexpensive. With just a few tools, you’ll have the door re-aligned and swinging freely in no time at all.
What Causes Diamond Doors?
A Diamond door tilts downward and to the side. Often, the sag is not visible when the door is open. But opening and closing the door causes the door to scrape the door jamb at the top. Doors with pronounced sags can stick to the point where it becomes difficult to open or close the door.
As houses age, it is not uncommon for doors to begin to sag. In most cases, the source of the problem can be traced to the top hinge. Screws in the top hinge may turn loose or they may begin to pull straight out.
Hinges are durable fixtures that can last for decades. But in some cases, the hinge leaves or the hinge pin may begin to wear out. Loose hinges may need new pins or may need to be replaced entirely.
Sometimes, a previous owner may have added a spacer to the top hinge. The spacer may be a thin strip of cardboard inserted under either hinge leaf and likely was designed to cause the door to fit into the frame more tightly.
Paint or stain may have been added to the mortise in the door or door jamb. Sometimes, doors are removed for painting and the entire door edge is painted or stained. Extra layers of paint or stain act like spacers to push the door out of alignment.
