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.
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.

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.

If your floor has noticeable scratches throughout, your best option is to sand down the floor and refinish it. A complete sanding removes scratches, but beware: This only works on real wood floors, not bamboo. If you have an engineered wood floor with a real wood surface, make sure the real wood surface is more than 1mm thick—sanding usually takes at least this much wood off the surface, so a thicker layer is required for a complete sanding.

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: Denver Hardwood Floor Install

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 Floors
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.
