You will find at flooring stores a wide array of choices in flooring. The one that seems the best to me is the floated floor. Contact Harris-Tarkett@aol.com for information. This floor can go down over anything. An engineered floor required a subfloor of plywood, so if you hve pressed wood or composition floor, you do have a little more work. A glue-down and nail down also require a plywood floor, which you can put down yourself. A floating floor is the easiest and it can go down rather quickly. The finished product is hard to gell from a solid wood floor that goes down unfinished and you must put the finish on yourself. Watch out for pre-finished flooring and the warranties. I found several different time periods which correspond to the number of layers of polyurethane. 5 year warranty has fewer coats of finish than 10 year, for example. All of the material I have does indicate that the upkeep can be as much as a monthly process to keep the floors looking like new. But wood is permanent and beautiful. Good luck.
