in my 1920s home we have hardwood thoughout.. the old floorboard subfloor runs the same direction as the hardwood flooring. at each joint in the subfloor i have a gap of about 2 to 4mm in about 50percent of the flooring (mostly in the high traffic areas). is this typical in older homes? i would imagne that if the boards ran perpendicular to the subflooring this wouldn't have happened.. but im guessing whoever built the place is no longer.. and probably not taking questions..
i know why this is happening.. but is there anything i can do to repair this without tearing out all the flooring and replacing the subfloor?
also.. if i have a loose or extra creaky board.. is there any method of securing it down? without major work...
