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.
Installing a hardwood floor yourself can save you money – if you know what you’re doing. Improper preparation and installation can lead to warping and buckling, which will ruin flooring that would otherwise remain beautiful for years to come. The most important thing you can do to ensure the structural integrity of your floor is to properly prepare for the installation process. Here are various articles to help you!

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).

Warped hardwood floors, also known as sagging, is a serious problem for any homeowner. It is often the result of serious moisture problems, and any evidence of warped hardwood floors needs to be addressed immediately. Warped hardwood floors are rarely the result of faulty hardwood or installation, but are a symptom of larger moisture problems in the home itself that need to be taken care of.

We live in a 1924 home with very heavy thick oak woodwork thru out. It also has oak floors, quarter sawn in narrow strips, that In most rooms are in need of refinishing. We had a professional come & take a look yesterday, she said the flooring is too thin to sand & refinish. I was shocked, the floors have never been refinished. I was so disappointed. What can be done, if anything? We also have extended our kitchen & wanted to put oak flooring down to match the rest of the house. She said they don’t make this thickness anymore & the new flooring would be much thicker, therefore making it higher than the dining room that opens to it. Hardwood Floor
– If you want to change the width of the wood or the direction of the hardwood, the only way to do this is to get a new floor. The standard in home is oak 2 ¼” strip. Now, it’s more stylish and more common to get wider planks such as 3 ¼” or 4”or 5” planks. These look more modern and importantly make the room look larger. Another design trick to make the rooms look larger is to lay the planks on a diagonal – that way, it carries your eye along the longest length of the room. Or, you can even get fancy and add borders or do a herringbone pattern. Denver Hardwood Flooring
A buckled floor happens when the boards warp and lift up from the subfloor that they are attached to. You’ll most likely need to call in a hardwood floor installer to identify the root of the problem if buckling is an issue. Once the cause of your buckling has been identified, you’ll need to take the necessary measures to ensure that your hardwood planks are firmly attached to the subfloor so that the problem no longer persists.
Eliminate any problem spots to make the subfloor level. Sand minor humps down with a hand-held or orbital sander to make the subfloor level. To fill any dips or low spots, use a leveling compound (also known as floor patch). Mix up the compound according to package directions, fill in the dips, then pull your straight piece of lumber back and forth over the spot to flatten and level it with the rest of the subfloor.[7] Hardwood Floor
