Door hinges don’t last forever. Over time, they can degrade to the point where they no longer facilitate the smooth opening and closing of doors. When this occurs, you may want to replace them with a new set of door hinges. It’s a small investment that can protect your door from damage while also promoting a more energy-efficient home or space. Below are five telltale signs that it’s time to replace your door hinges.
#1) Cracks or Dents
If you notice cracks or dents in any of your door hinges, you should typically replace them. Door hinges are available in different materials, some of which are stronger than others. When made of weak materials, they may buckle under the weight of the door. This can result in the formation of cracks or dents that jeopardize their structural integrity.
#2) Sagging Door
Does your door sag? If so, you may want to replace the hinges connecting it to the frame. Hinges should stabilize the doors with which they are used, keeping them horizontal and level at all times. When a hinge fails, it may cause the door to sag. Replacing the failed hinge with a new, stronger hinge should solve the problem by stabilizing the door.
#3) Corrosion
Corrosion is a telltale sign that door hinges should be replaced. While some cabinet and enclosure hinges are made of plastic, door hinges are almost always made of a metal or alloy, such as aluminum, steel or brass. As a result, they are susceptible to corrosion. Exposure to moisture — even moisture vapor in the air — can cause oxidation that manifests in the form of corrosion. If left unchecked, corrosion can eat through hinges, which is why you should replace them.
#4) Loose Knuckle
A loose knuckle typically means it’s time to replace a door hinge. Like most other hinges, door hinges feature two leafs that interlock to form a central joint known as a knuckle. The knuckle essentially allows the door to rotate away from the adjacent frame to which it’s connected. Over time, however, knuckles can become loose from this constant opening and closing action.
#5) Large Gap
If you notice a large gap between where a door hinge closes, you should consider replacing it. Ideally, door hinges should close tightly, resulting in little or no visible space. A large gap typically means the door hinge has come loose or otherwise failed. And if you don’t replace it, this large open space will allow air to leak out of your home while subsequently jacking up your energy costs.
