I occasionally perform door modifications for my customers.
This interior door required trimming, hinge-routing, and installation.
Setting up the door to route the hinge locations…
Locations measured and marked for the hinges.
Unfortunately, I often get busy and forget to take pictures of the finished product.
The cost to modify and install a door to fit an existing jamb, in Fort Collins, in October 2020, ranges from $150 to $250 (Labor only) and depends widely on the existing conditions of the door and jamb.
