We had bought and installed this beautiful product in our downstairs a few years ago. It's now time to do the upstairs and the product was the same excellent value for the price. Arrived quicker than we needed, but gives it time to acclimate to our home. We will be using the same installer and he was happy we are ordering the same product from the same company. He was VERY impressed by the quality of the product last time. I'm excited to see the completed project as I love this wood on our main floor.
A number of proprietary features for solid wood floors are available. Many solid woods come with grooves cut into the back of the wood that run the length of each plank, often called 'absorption strips,' that are intended to reduce cupping. Solid wood floors are mostly manufactured 0.75 inches (19 mm) thick with a tongue-and-groove for installation. Hardwood Floors
You cannot restore every wood floor by simply refinishing it. If your wood floor has become warped or if several of the planks have become damaged, you will typically need to replace the entire floor, as finishing will only brighten an already-damaged surface. On really old floors, you may see the tongue where the boards come together, or your boards may lack adequate thickness. Floors like this are definite candidates for replacement, as refinishing is purely cosmetic. Denver Hardwood Floor Install
Tongue-and-groove: One side and one end of the plank have a groove, the other side and end have a tongue (protruding wood along an edge's center). The tongue and groove fit snugly together, thus joining or aligning the planks, and are not visible once joined. Tongue-and-groove flooring can be installed by glue-down (both engineered and solid), floating (mostly engineered only), or nail-down (not recommended for most engineered). Hardwood Floors
Wood flooring can also be installed utilizing the glue-down method. This is an especially popular method for solid parquet flooring installations on concrete sub-floors. Additionally, engineered wood flooring may use the glue-down method as well. A layer of mastic is placed onto the sub-floor using a trowel similar to those used in laying ceramic tile. The wood pieces are then laid on top of the glue and hammered into place using a rubber mallet and a protected 2x4 to create a level floor. Often the parquet floor will require sanding and re-finishing after the glue-down installation method due to the small size pieces. Denver Hardwood Flooring
There are some characteristics that are common to each category: solid wood is more frequently site-finished, is always in a plank format, is generally thicker than engineered wood, and is usually installed by nailing. Engineered wood is more frequently pre-finished, has bevelled edges, is very rarely site-finished, and is installed with glue or as a floating installation. 
Laminate is a cost effective option that will withstand a certain amount of wear. For an easy installation, opt for click-lock. The planks will snap together and can be laid over other flooring. It is ideal for living areas, and some brands may even construct it with a waterproof core, allowing it to be used in areas where water may be an issue. We suggest taking a close look at the guarantee before installing it in a bathroom. Hardwood Floors
If your floors are in need of a deeper cleaning, use a wood floor cleaner. Follow the instructions for diluting the cleaner in water. Clean the floors with a damp mop, going with the grain. Then, go back over the floor with a clean, damp mop to remove any excess cleaner. Finish by drying the floor completely with a dry towel. Remember, leftover standing water could damage your wood floors. Denver Hardwood Flooring
Glue down engineered hardwood, alternatively. If you don't want to nail down the boards, you do have the option of using adhesive to put engineered hardwood in place. It's a good choice, but won't last as long or be as sturdy as nailed down hardwood. The procedure is very similar to the nail-down process. Follow the adhesive manufacturer's instructions for installation and drying times.
