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

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] Denver Hardwood Floor Install
Over the years, many hardwood floors develop small splits or cracks in the surface of the wood. These can be spot repaired with some angled nails to secure the two pieces together, along with some wood putty to hide the blemishes. If your floor is suffering from large cracks, however, you might want to think about refinishing the floor. And if the split is particularly bad, you should probably replace the damaged plank altogether. Denver Hardwood Floors

The natural process of things will tend to close gaps as the weather and humidity changes. As a rule, if the gap is less than the thickness of a dime, your flooring is normal and there’s nothing to worry about. If your gaps are more persistent, you might need to call in a professional to tighten up your hardwood floor so that they cease to be a problem. Denver 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.[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.

Floating installation: A floating installation is where the flooring is laid down in a glueless manner on top of a layer of underlay. The individual planks are locked together, and are not glued or nailed down to the subfloor. By doing this the floor is floating above the underlay, and can be laid on top of existing tile or marble, without the risk of damaging the subflooring.
Engineered wood flooring was created to lower the cost of wood flooring and attempt to fix some of solid wood’s shortcomings. It’s constructed from inexpensive plywood or particle board and topped with a thin veneer of hardwood. This construction helps with installation flexibility and slightly improves indent performance, but it adds a new set of problems as well. Because the “real” wood part of the floor is just a thin veneer, damage from scratches can be irreparable. Engineered wood floors are still made from porous wood, meaning they can’t be subjected to water. Denver Hardwood Floors

It can be sanded down and refinished five, six, even seven times. And, if maintained properly, you won’t have to do it for 20 years. Refinishing a floor may be messy and troublesome, but most homeowners learn to live with it. After all, it costs five times as much to replace hardwood floors than it does to refinish them. For some people that is reason enough. Hardwood Floors

For example, moisture can be a factor, as variations in moisture can lead to gapping and warping. For this reason, installing hardwood flooring in full bathrooms is not recommended because of the fluctuating moisture levels. Follow manufacturer recommendations relating to moisture before selecting and installing hardwood. For more protection against moisture, use a moisture barrier.


Put on gloves, knee pads, and protective eye glasses. You'll be working diligently on your hands and knees for hours to complete this project, especially if you're doing a large space. Invest in a good pair of knee pads to protect your knees. Sturdy work gloves will protect your hands from splinters, and goggles will prevent sawdust and other debris from getting into your eyes.[1] Hardwood Floors

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. Hardwood Floors
Make cuts perpendicular to the direction the wood is laying. Using a circular saw, make single cuts straight across the flooring that are about 1 foot (30 cm) to 2 feet (61 cm) apart. Be sure your cuts are perpendicular to the direction of the wood. Start on 1 side of the room and work your way systematically to the other side, spacing each cut about 1 foot (30 cm) to 2 feet (61 cm) apart.[3] Denver Hardwood Flooring
This process begins with the same treatment process that the rotary peel method uses. However, instead of being sliced in a rotary fashion, with this technique the wood is sliced from the log in much the same manner that lumber is sawn from a log – straight through. The veneers do not go through the same manufacturing process as rotary peeled veneers. Engineered hardwood produced this way tends to have fewer problems with "face checking", and also does not have the same plywood appearance in the grain.[3] However, the planks can tend to have edge splintering and cracking because the veneers have been submerged in water and then pressed flat.

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. Keep reading to learn more about hardwood floor installation costs.

Solid hardwood is great for high traffic areas and rooms on the first or second floors where there’s limited moisture. You can purchase your solid hardwood floors either prefinished or unfinished. Prefinished hardwood floors have a coating that protects them and they’re ready to install right out of the box. Unfinished hardwoods allow you to apply your own stain color.
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.
