How much should it cost to have a fire-rated, panel door installed (labor and materials)?
Answers:
I am guessing that this will be an interior door between an attached garage or utility room and the living space of the house. You are looking for a solid core door, but you do not mention whether it will be painted or stained and varnished. There will be a price difference between the two. I also assume that it is a standard sized door and that you will reuse the existing door frame, hinges, and lockset.
Best bet is to use the services of a local handyman. Since you are a Yahoo user, why not try the Yahoo Yellow Pages:
