You may be on the fence about your decision to refinish your hardwood floors because you wonder if your floors are a candidate for refinishing. The truth is, not all hardwood floors can be refinished. Although most common problems can be addressed and fixed without replacing the entire floor, there are some exceptions. Consider the following to make an informed decision. Denver Hardwood Flooring
Wood flooring is any product manufactured from timber that is designed for use as flooring, either structural or aesthetic. Wood is a common choice as a flooring material and can come in various styles, colors, cuts, and species. Bamboo flooring is often considered a form of wood flooring, although it is made from a grass (bamboo) rather than a timber. Hardwood Floors
Glue down engineered hardwood, alternatively. If you don't want to nail down the boards, you do have the option of using adhesive to put engineered hardwood in place. It's a good choice, but won't last as long or be as sturdy as nailed down hardwood. The procedure is very similar to the nail-down process. Follow the adhesive manufacturer's instructions for installation and drying times. Denver Hardwood Floors

If your floors are in need of a deeper cleaning, use a wood floor cleaner. Follow the instructions for diluting the cleaner in water. Clean the floors with a damp mop, going with the grain. Then, go back over the floor with a clean, damp mop to remove any excess cleaner. Finish by drying the floor completely with a dry towel. Remember, leftover standing water could damage your wood floors. Hardwood Floors
You cannot restore every wood floor by simply refinishing it. If your wood floor has become warped or if several of the planks have become damaged, you will typically need to replace the entire floor, as finishing will only brighten an already-damaged surface. On really old floors, you may see the tongue where the boards come together, or your boards may lack adequate thickness. Floors like this are definite candidates for replacement, as refinishing is purely cosmetic.
To fix a buckled floorboard, you need to be able to access the floor from below. The way to tackle this problem is to put weight on the buckled area from above — a cement block works well. Then install a 1 1/4-inch screw in the buckled flooring from below. Allow the screw to penetrate only halfway into the flooring, or it may come up through the finished surface. Driving the screw through the subfloor and into the flooring pulls the flooring down against the subfloor and gets rid of the buckled spot. Denver Hardwood Floor Install
Instead of boiling the hardwood logs, in this process they are kept at a low humidity level and dried slowly to draw moisture from the inside of the wood cells. The logs are then sawn in the same manner as for solid hardwood planks. This style of engineered hardwood has the same look as solid hardwood, and does not have any of the potential problems of "face checking" that rotary-peel and slice-peel products have, because the product is not exposed to added moisture.

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.

Floor connection system: There are a wide range of connection systems, as most of them are mill-specific manufacturing techniques. The general principle is to have grooves on all four sides of the plank with a separate, unconnected, piece that is inserted into the grooves of two planks to join them. The piece used for the connection can be made from wood, rubber, or plastic. This installation system allows for different materials (i.e. wood and metal) to be installed together if they have the same connection system. Denver Hardwood Floor Install
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.
Refinish, refinish, refinish! In almost every case it is preferable to refinish rather than replace hardwood floors. Part of the appeal of hardwood is that it lasts so long. A quality hardwood floor can be sanded down and refinished at least six times, and up to ten times before you need to replace it. You can change the color, closely match and replace warped, stained, or termite ingested planks, silence squeaky boards, and fill gaps or patch knots. With all of these easy solutions, why would anyone choose to replace hardwood floors? Well, here are the cases when a complete rehaul becomes a better option. Denver Hardwood Floors
Generally, hardwood floors need to be buffed every 3–5 years. The process usually takes about one day. Buffing refers to the process of using a stand up floor buffer. The floor is abraded with 180 grit screen on the buffer. This allows for the new coat of finish to mechanically adhere to the floor. This process works with great results as long as the floor hasn't had any waxes or synthetic cleaners. Denver 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. 
If you face medium scratches that show only slight damage, you may be apply to apply a new coat of finish to the area without having to refinish the floor entirely. Make sure the finish matches the original as closely as possible. If the wood was stained but has no finish, you may be able to get similar wood floor scratch repair results by re-applying the stain to help hide the scratch.
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. Hardwood Floors
Because tongue-and-groove boards are locked in place, removal involves cutting out the middle of each damaged board. The easiest way is to bore a 1-in.-dia. hole through both ends of each damaged board (photo 1). Then use a circular saw to connect the two holes (photo 2). Follow these steps to safely make the plunge cuts you need to repair your hardwood floors: 1. Adjust the depth of cut to the thickness of the floorboards. Plug in the saw and put on eye protection. 2. Pull back the retractable blade guard with your thumb. Then hold the nose of the baseplate on the floorboard and lift up the rear of the saw. 3. Align the blade with the right edge of one of the holes. Make sure the blade isn't touching the floor, then squeeze the trigger and slowly lower the spinning blade into the board. 4. Grip the saw firmly with both hands and guide it in a straight line until you cut into the right edge of the hole at the opposite end of the board. 5. Move back to the first hole, align the blade with the left edge and cut to the left edge of the second hole. Pry out the middle section with a hammer and chisel. Chop out the remaining edges, being careful not to damage any surrounding boards (photo 3). The "tongue" piece will be nailed in place, so break it out in small pieces. Then pull out the nails with a hammer or locking pliers. The existing floorboards have a tongue and groove milled on each end and along the edges. Chop off the tongue exposed by the board you just removed so you can slip in the new board (photo 4). Hardwood Floors
Cupped floors, also called washboarding, develops gradually across the width of the wood strip where the edges of the hardwood planks raise up and the center of the board sinks down. The cause of cupped floors is a moisture imbalance where there is more water on the bottom side of the wood plank than on the top. The only cure is to balance the humidity levels in your home, and to give the surface time to return back to normal. After the floor has stabilized, you can have a professional sand it flat and re-finish it to perfection. Hardwood Floors
