Can I shorten a Fiberglass door.
My wooden front door is in bad shape and needs to be replaced. It is a solid wood door and I would like to have one with some glass lites at the top. House is stucco on block construction With outside stucco right up to the brick mold. Frame is in great shape, Cypress wood with a nice inside molding treatment. I do not want to replace the whole frame, just the door itself. The door is standard 3-0 wide but is only 78.5" tall. I have a pre-hung fiber glass door, 3-0 by 6-8 that I would like to use as a replacement. The width is perfect but I would need to cut some off the bottom. My thought is cut the door and install a replacement door sweep where I cut. I also have to remortise the hinges, either on the jamb or on the door and relocate the strike plate on the jamb. All easy enough.
Question is: if I cut the door will I expose a cavity at the bottom of the door like a hollow core interior door? Will I destroy the integrity of the door? Would I be better cutting the top of the door? Any ideas or suggestions welcomed.
