The cost of repairing your door depends on the amount of damage it has experienced, the issue with the door, and the material of the door. For example, if your door is experiencing swelling and sticking, simply sanding down the part of the door that sticks out and doesn’t fit in the frame is easy and not that costly. Sagging of a door is also fairly easy to repair, which requires switching out the current hinges with new ones. These repairs typically start as low as $50. Fixing exterior doors, however, are usually harder and more expensive to fix than interior doors because exterior doors are usually made out of more durable materials like steel and aluminum. Wood doors are typically easier to fix due to their flexible nature to sand and shape into a door frame. Door repairs are typically between $150-$250. If your door has experienced severe damage and dents, you may need to get it replaced. Consult your local door repair contractor for expert advice on your door repairs.
