It all begins when you notice the scratch on the ground, which is becoming more and more abrupt. Until the day comes when it makes a high-pitched noise more like a haunted mansion than a family home. Or even difficult to close. You would not have this problem in the case of a sliding door, but if yours always rubs against the ground, it has an easier solution than you might think. It is not necessary to disassemble it or make a great effort to fix it, just follow a simple advice.
But why do doors sometimes rub against the ground? With the passage of time, particles of all kinds, mainly dust and dirt, accumulate to the point of hindering the opening and closing movements of the door. It is usually the most common cause, although the truth is that it can also be due to other reasons.
In the event that the door does not work normally and rubs against the ground due to dirt, the remedy will be very simple. You won’t even need to remove the door. It will simply be enough to get hold of a sandpaper, which will have to be placed just below the door. This method consists of opening and closing it so that the sandpaper eliminates all the excess from its lower part, until it no longer touches the ground and can be used normally.
If dirt buildup isn’t the problem, another common cause of a door rubbing against the floor has to do with the hinges, specifically the fact that the door has sagged a bit. Slamming doors or other blows are usually the most common reason, for example, due to the action of the wind. If the door hinge has moved out of place or has come loose, it will be necessary to shim the door to properly position and/or tighten the hinge screws.
These would be the easiest cases to fix, however, it could also be that the door rubs against the floor not because of it, but because of the floor itself because it has swollen. This would be one of the worst scenarios, since its solution is not that simple. In these cases, the floor would have to be fixed, but the repair would cost considerable money and time. However, you can get out of the way by lowering the bottom of the door. It may not be the most desirable option, but it will certainly be a better alternative for those who prefer to avoid a construction site.
