What it costs: From $1.50 to $8 per square foot depending on wood thickness, species, and grade. Some prefinished solid-wood and engineered wood floors are DIY-friendly, but if you plan to hire a pro installer, tack on $2 per square foot, minimum.
How it will hold up: Some prefinished solid-wood boards come with a 50-year warranty. With regular care, though, any solid-wood floor can easily last twice that long. Warranties on the finish for engineered wood range from 10 to 30 years.
How to maintain it: Fight a finish's biggest enemy—abrasive dirt—by vacuuming regularly and laying runners and doormats near entries.
Where to install it: Just about anywhere, except in areas prone to extreme humidity and standing water.
