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. [6]
When it comes to budgeting for this project, you have many factors to consider. Two of the largest considerations include the cost per square foot of the materials and the cost per square foot for installation. To help you understand the potential costs of installing hardwood, we researched the average cost per square foot for traditional and engineered flooring at three different price points.

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).
Engineered wood flooring consists of two or more layers of wood adhered together to form a plank. Typically, engineered wood flooring uses a thin layer (lamella) of a more expensive wood bonded to a core constructed from cheaper wood. The increased stability of engineered wood is achieved by running each layer at a 90° angle to the layer above. This stability makes it a universal product that can be installed over all types of subfloors above, below or on grade. Engineered wood is the most common type of wood flooring in Europe and has been growing in popularity in North America[4]. Denver Hardwood Flooring

Solid wood flooring is milled from a single piece of timber that is kiln or air dried before sawing. Depending on the desired look of the floor, the timber can be cut in three ways: flat-sawn, quarter-sawn, and rift-sawn. The timber is cut to the desired dimensions and either packed unfinished for a site-finished installation or finished at the factory. The moisture content at time of manufacturing is carefully controlled to ensure the product does not warp during transport and storage. Denver Hardwood Floor

My boyfriend and I recently bought a new house that requires many updates, including floors. The house was built in 1960 and has beautiful original hardwood floors that were covered in carpet. The day we moved in (scratch that: the HOUR we moved in), we pulled up the carpet and had ambitious plans to refinish the floors with a more modern stain. After multiple attempts with rented drum sanders and 12×18 sanders, the floors were just OK. We tried using our own belt sander and palm sander to even out hard to sand areas, particularly the edges, but the end-result was not ideal. We tried our hand at staining anyways because we were fed up with staining (not the greatest idea!). Our floors are unevenly taking the stain and are not up to our standards. Now our question is: do we hire someone to professionally refinish the floors (quotes we have obtained range from $4-5 per square foot) OR replace the floors entirely. Do you have any advice??

The age of your floor also plays a role. If your floor has been in place for decades, it may resist refinishing for a number of reasons. For instance, if it has already been refinished several times or if too much of the surface wood has become exposed, refinishing your floor may have little effect. For very old floors, replacement can often be preferable to refinishing. Denver Hardwood Floor
Refinishing can actually take much more time than fully replacing a wood floor. Refinishing is a messy, meticulous process than can take approximately four to five days, during which the floor surface must remain completely untouched. The process requires sanders, edgers, buffers, scrapers, brushes, base coat sealers, topcoat sealers, putty knives and sometimes paint. Replacement, on the other hand, can be done in considerably less time using only lumber, a couple of saws, measuring tape, a flat bar, a chalk line and a nail gun. Denver Hardwood Floor
Engineered wood flooring has other benefits beyond dimensional stability and universal use. Patented installation systems allow for faster installation and easy replacement of boards. Engineered wood also allows for a floating installation where the planks are not adhered to the subfloor or to each other, further increasing ease of repair and reducing installation time. Engineered flooring is also suitable for underfloor and radiant heating systems. Denver Hardwood Floor Install
No matter what type of hardwood flooring you choose, proper care and maintenance will help them look beautiful even longer. First off, don’t let the dirt and dust collect. At least once a week, you’ll want to go over your hardwood floors with a broom or dust mop to pick up any dirt, dust, hair or pet dander. If you’re using a vacuum, make sure it’s set to ‘wood floors’ so that you’re not beating up your floors and damaging them in the process.
Like anything, whether you refinish your hardwood floors or replace them depends on your personal circumstances. If you are about to move into a new home, refinishing your hardwood floors is much easier vs. if you already live there. Clearly the cost to refinish the floors Is much less expensive than replacing them (For perspective, to replace them may cost 3-5 times as much). Denver Hardwood Floor Install
Natural warmth and beauty make wood a favorite for floors. But when the topcoat finish wears through, the porous surface of the wood is open to stains-especially beneath dining room chairs, in front of a sink and in other high-traffic, high-spill areas. Oil soap and all-purpose cleanser remove some stains, especially when the spill is fresh. But it's impossible to scrub out stains that have soaked into the wood fibers. And sanding only creates a depression in the floor that's more noticeable than the stain. The only option to repair hardwood floors at this point is to cut out the stained floorboards and install new ones. We replaced a couple of boards from a standard 3/4-in.-thick x 21/4-in.-wide oak-strip floor using a drill, circular saw and sharp chisel. To determine the exact width and thickness of the pieces you'll need, lift up a heat register or threshold and measure the exposed ends of the floorboards. You'll find hardwood flooring at a local millwork shop, lumberyard or floor-covering store. Denver Hardwood Floor
Awesome explanation! When I say heat pump to people, it's amazing how often their eyes glaze over...even though most of them have had refrigerators and air-conditioners their whole lives and have never asked themselves how they work. Same principle! Compressor and expansion valve (and the heat-holding capacity of a phase change; another confusing one for people). thanks for helping educate! Denver Hardwood Flooring
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.

Choose your replacement hardwood flooring. You don't have to replace your old floor with the exact same wood or flooring type that you just removed! You can glue your new hardwood flooring into place if you like. You can also install nail-down, floating (or locking) hardwood flooring as a replacement. The choice is up to you and what your budget allows. Denver Hardwood Floor Install
Hardwood species used in flooring are given a hardwood hardness rating, which indicates how resistant the wood is to dents and wear. This rating is based off a test called the Janka Hardness Test, and it measures the force needed to press a steel ball into the wood sample. The highest possible score on this test is a little over 5,000, with most traditional solid wood floors scoring in the 1,000-2,000 range. The superior density of Rigid Core flooring would exceed the limitations of the Janka test, and instead a higher impact testing is needed to measure real world performance. Here is how the general hardness of plank flooring ranks:
Most floors use a tongue-and-groove design for connecting adjacent strips. This design makes replacing a single strip or plank challenging, but not impossible. First, look for any nails in the damaged board and drive them as far through the board as possible by using a hammer and nail set. Carpenters use nail sets to drive nails flush with trim without damaging the trim with a hammer. After you’ve cleared the nails, it’s time to remove the damaged board and install a new one. Follow these steps:
Solid hardwood floors are made of planks milled from a single piece of timber. Solid hardwood floors were originally used for structural purposes, being installed perpendicular to the wooden support beams of a building known as joists or bearers. With the increased use of concrete as a subfloor in some parts of the world, engineered wood flooring has gained some popularity. However, solid wood floors are still common and popular. Solid wood floors have a thicker wear surface and can be sanded and finished more times than an engineered wood floor.[2] It is not uncommon for homes in New England, Eastern Canada, USA, and Europe to have the original solid wood floor still in use today.
