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.[6] Denver Hardwood Floor Install
```Another common hardwood floor malady is the development of gaps between planks. The most common causes of gaps between the boards is Mother Nature. Wood shrinks as it dries out, and it expands when it gets wet and humid. That regular expansion and contraction over time is the most common cause of gaps, and is the main reason why most gaps are seasonal in nature. Perhaps your best plan of action is to exercise patience. Denver Hardwood Floor Install

Measure rooms one at a time. It’s easiest to measure rectangles, so if you have an “L-shaped” room, divide it into 2 rectangles and measure them separately. The length of the rectangle multiplied by the width equals the square footage. For example, a room, or section of a room, that is 20 feet long and 12 feet wide produces this formula: 20 x 12 = 240 square feet. If the flooring you are purchasing is sold by the yard, divide the square feet by 9. So, 240 square feet / 9 = 26.667 square yards. Denver Hardwood Floor
No matter which type of flooring you choose, if the subfloor, joists or other structural elements need work, you can expect to pay considerably more in both labor and materials. Plywood for the subflooring averages \$22 for each 4-foot by 8-foot sheet. For a 12-foot by 12-foot room, you’d need five sheets of plywood, which increases the cost by \$110. Additionally, carpenters often charge \$20 to \$35 per hour to install new floor joists and subfloors.  For laying a hardwood floor over concrete, it's best to use a floating floor system where the floor is not glued to the concrete.  Wood flooring is a major investment, so always have the concrete checked for moisture prior to installation.

Maple is another great choice for hardwood flooring. Many people prefer its light tan look, which blends into home interior spaces. As one of the strongest woods, maple is a top choice for high-traffic areas of a home. The wood doesn’t scuff easily, making it a good choice for homes with children or those with a lot of foot traffic across the floors. Maple requires minimal maintenance, with weekly sweeping and annual applications of wood soap to prolong the life of the floors. Denver Hardwood Floor
Warranty & Brand – The value of your floor extends well beyond the floor itself. The people that created, tested, produced, and support it are just as important to consider. You want to make sure you are buying a floor from a manufacturer who you can trust. What kind of testing are they doing to make sure the floor you are buying will last? How can they help you if problems do occur down the road? What does the warranty actually cover? These are important factors to consider, especially when hardwood flooring doesn’t meet Rigid Core flooring’s abilities in areas like durability, dent resistance, and waterproofing.

```Width & Length – Plank flooring comes in a variety of widths and lengths. The most common widths are currently in the 5” – 6” range, but wider widths are rapidly becoming more popular. The length of your floor is also important to consider depending on the size of your space. Hardwood flooring comes in mixed lengths because imperfections are cut out of longer planks during production. Rigid Core flooring is built to size and comes in lengths ranging from 36” up to 80+”.

Solid hardwood floor planks are made from a piece of wood and made to be anywhere from 18 to 20 mm thick. The boards are made with a tongue and groove to fit together for installation. Depending on the species of wood, certain floors will be harder than others. The harder the floor, the less susceptible it is to dings and scratches. The floor can be sanded and refinished several times to restore its beauty, with the total number of times being determined by the depth of the tongue from the top of the plank.

```Cut a new length of flooring to fit snugly into the space of the old board. It doesn't matter what kind of saw you use to repair your hardwood floors; just make sure the cuts are perfectly square. After trimming the board to length, turn it upside down and use a chisel to chop off the lower lip of the grooved edge (photo 5). That allows it to fit over the protruding tongue of the adjacent floorboard. Test-fit the new piece. If it's slightly lower than the surrounding floorboards, shim it up with strips of kraft paper. Then remove the board and spread carpenter's glue on the tongues and grooves of the new and old pieces. Slip the new board into place (photo 6), protect it with a scrap-wood block and tap it down with a hammer. Cover the board with wax paper, then hold it down overnight with heavy books or weights. An alternative to gluing: Simply face-nail the board with 6d finishing nails. Bore pilot holes at a slight angle, then drive in the nails. Tap them below the surface with a nailset (photo 7) and fill the holes with wood putty. Lightly sand the entire board smooth, but be careful not to remove too much finish from surrounding boards. After finding a matching stain color by experimenting on scraps of flooring, stain the boards to match the original floor. Let dry overnight, then apply two coats of clear polyurethane varnish. If the old floor is unstained, just apply the polyurethane.

Price is the first obvious variable to consider. It is almost always cheaper to refinish your floor than to replace it. When replacing, you must consider the cost of the new wood as well as the installation. You can offset much of this cost by installing the floor yourself, but this is a very invasive process that requires specialized knowledge and precision. You can typically refinish a wood floor yourself, with just a few inexpensive solutions. Denver Hardwood Flooring
This process involves treating the wood by boiling the log in water. After preparation, the wood is peeled by a blade starting from the outside of the log and working toward the center, thus creating a wood veneer. The veneer is then pressed flat with high pressure. This style of manufacturing tends to have problems with the wood cupping or curling back to its original shape. Rotary-peeled engineered hardwoods tend to have a plywood appearance in the grain.[3] Hardwood Floor

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.[5] 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.
