Doors that drag on the floor can be a nuisance, and can even cause damage to the flooring. Fortunately, there are several ways to stop a door from dragging on the floor.
The first step in fixing a door that is dragging on the floor is to identify the cause of the problem. In many cases, the door is simply out of alignment, and can be easily adjusted. To check the alignment, stand inside the room, and close the door. If the door is not closing properly, it is likely that the door is out of alignment.
Once it has been determined that the door is out of alignment, there are several methods that can be used to adjust the door. The most common method is to adjust the door hinges. To do this, loosen the screws on the door hinges, and then move the door slightly in the direction needed to close it properly. Once the door is in the correct position, tighten the screws to secure the door in place.
Another method for adjusting a door that is dragging on the floor is to adjust the door jamb. The door jamb is the frame that holds the door in place. To adjust the door jamb, loosen the screws on the jamb, and then move the jamb slightly in the direction needed to close the door properly. Once the jamb is in the correct position, tighten the screws to secure it in place.
In some cases, the door may be dragging on the floor due to a worn out threshold. If this is the case, the threshold will need to be replaced. To replace the threshold, remove the old threshold, and then measure the width of the door opening. Purchase a new threshold that is the same width as the opening, and then install it in place.
Finally, if the door is still dragging on the floor after adjusting the hinges, jamb, and threshold, it may be necessary to adjust the flooring. If the flooring is uneven, it can cause the door to drag. To adjust the flooring, use a level to determine the high and low spots, and then use a floor jack to raise or lower the flooring to level it out.
By following these steps, it is possible to stop a door from dragging on the floor. However, if the problem persists, it may be necessary to contact a professional to inspect the door and flooring to determine the cause of the problem.
