Will Heavy Bookcases Make My Floor Sag?
If you have some concern that your bookcase is so heavy it is making your floor sag, the obvious answer is to distribute the weight horizontally to prevent further damage or break up the weight between several smaller bookcases. Depending upon the exact problem, repairing a sagging floor might be as easy as jacking up the low spot and adding shims to bring it back level, or as complicated as adding new supports and pylons that might cost thousands of dollars. It makes sense to have an experienced floor contractor offer an opinion of the cost and scope of the operation first.
