What can I do to repair squeaky floors? My house is about 20 years old, and built over a crawl space, with squeaking sections of floor under hardwood and carpet. In fact, when I installed a new, heavier refrigerator in the kitchen I started to get a "groan" every time I step in front of the cabinets adjacent to the fridge. Another area is around the bed in the master bedroom. The underside of the floors in the crawlspace is fully insulated. Any solutions for fixing my squeaky floors?
