Changing the structure of a floor to support new load bearing walls is major work, and thus costly. Restructuring a floor involves several time-consuming steps, resulting in high labor costs. The process will involve modifications to framing, sub-flooring, flooring and floor covering. Changes to floor structure can also create a need for additional work, such as changes to the floor in adjoining parts of the home, changes in the load carried by walls and the foundation, and in some cases results in the need to modify cabinets, appliance positions, and a host of other possible changes. If you are considering changes to a first floor above a finished basement or to second floor areas, consideration must also be given to the effect of the planned changes on the spaces below your remodel. These changes could require new ceiling work in the space below and could even affect headroom. In addition, you could create a need to make changes in electrical, plumbing, or duct work. All of these cost elements can add up very quickly to a significant expense.
