The costs of installing doors vary greatly based on the types of doors, door frames, trim replacements, fittings used for the job.

Door Repair Cost
When given a choice between repairing a door and replacing it, most people choose to replace it. Doors are generally replaced because the repair and replacement costs are almost equal. Still, there are times when it is better to repair your door.
Door repair costs vary as much as the types of doors installed and the conditions under which they are used. Common problems include door sagging, door swelling, dents/chips in the doors, damage to the door frame, and hardware and locks that need to be replaced. The budget you set for this depends on if you are doing the work yourself, hiring a general handyman, or employing a licensed professional to fix the problem for you. Some common problems and the average cost of repairing them are in the chart below.

Rotted Door Frame: Repair or Replace?
When deciding whether you will repair or replace your rotted door frame, you should carefully examine the condition of your door frame. First, examine the door frame to determine if there is any rot and the extent of the rot if you find some. Signs of rot include discolored wood (e.g., yellow or brown discoloration), rooted-up paint, bumps in the wood, and wood powder falling from the door when you tap it or shake it.
Then, repair the door frame if the rot is located at the bottom of the frame, the rotted area is not too big, the door frame is not too old, and there are no large bumps in the frame.
If there are rotted sections in different parts of it, if it’s old, if it has been repaired before and the rot has come back, or if the frame has been damaged, replace the door frame. Other signs that may require you to replace the door frame are if the frame is warped, skewed, or otherwise ineffective. You may also consider the overall cost of replacing or repairing the door frame. If the costs are about the same, then replace the door frame. By replacing the door frame, you are less likely to have rotting problems in the near future, you save money, and you are likely to resolve other door frame-related problems.

If your door frame needs to be replaced, it will cost you between $350 and $850. This is the average range of costs associated with a door frame replacement. The total cost will be affected by the costs of labor, material, and any cosmetic work you have done after replacing the door frame.
