Check the flatness of the subfloor. Use a straight piece of lumber that is between 8 and 10 feet in length to find any areas of the subfloor that aren't level. Simply lay down the plank and look for dips beneath it or raised humps. Mark any problem spots you find. Move the plank across the floor 1 way, then turn it diagonally and go across the surface again. Hardwood Floors
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.  Hardwood Floors
It is difficult to compare solid wood flooring to engineered wood flooring due to the wide range of quality in both product categories, particularly engineered. Solid wood has some limitations. Recommended maximum widths and lengths are typically 5" / 127mm wide and 7' / 2100mm long. Solid hardwood is also more prone to "gapping" (excessive space between planks), "crowning" (convex curving upwards when humidity increases) and "cupping" (a concave or "dished" appearance of the plank, with the height of the plank along its longer edges being higher than the centre) with increased plank size. Solid wood cannot be used with underfloor radiant heating. However extra care is necessary with the planning and installation of the heating system and the wood flooring, such as limiting the temperature to 85 °F (29 °C), avoid sharp temperature fluctuations, utilizing an outdoor thermostat to anticipate heating demands, and monitoring the moisture content for the subfloor before installation.
Durable and available in a variety of colors, hardwood flooring is a classic option for any home. Installation prices vary depending on the type of wood you choose. Depending upon your selections, the total cost for hardwood floor installation, including labor and materials, can average up to $6 to $8 per square foot.

Oak has always been a popular choice for hardwood flooring. The color is visually appealing, looks inviting, and has many advantages. You’ll find the wood easier to clean, and it easily blends in with furniture and home interior designs you already have. Plus, oak is a good investment if you’re considering selling your house in the future, since the wood can last for many years. Hardwood Floors
