Choosing hardwood floors for your home can increase its value as well as give it a refined look and feel that you will enjoy for many years.  Depending on the type of foundation and sub-floor you have installed, you can choose between several hardwood flooring materials.  Traditional crawlspace or homes with basements typically have wooden joists and sub-floors. With a wooden base, you can install any variety of hardwood flooring material, including thick tongue and groove hardwoods that must be nailed down. For homes with concrete slabs or similar sub-flooring, your options are typically limited to engineered hardwood flooring products that are generally thin wooden veneer with a hardboard backing that can be installed on any floor.   Since we are on a slab foundation, we are utilizing the engineered hardwood to achieve our flooring needs.
