Another common hardwood floor malady is the development of gaps between planks. The most common causes of gaps between the boards is Mother Nature. Wood shrinks as it dries out, and it expands when it gets wet and humid. That regular expansion and contraction over time is the most common cause of gaps, and is the main reason why most gaps are seasonal in nature. Perhaps your best plan of action is to exercise patience.
In general, it will almost ALWAYS be less expensive to refinish your hardwood floors. If you replace them, you need to pay for additional wood as well as ripping up and hauling away existing hardwood. If portions of your hardwood are damaged (e.g. pet stains or minor water stains), you can replace these sections and when you refinish them and it will all look new. Even if you have this, it will still be less expensive then replacing the whole floor.
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). Denver Hardwood Floor Install
I love it! I actually have an entire wall dedicated to most of my hand tools. And I want to build a miter station along one wall at some point. I’m tempted to add a bunch of drawers for a clean look and to keep dust travel off of shelves, but I have a serious “out of sight, out of mind” mentality. I think I’m going with shelves and a few drawers as a compromise. Outstanding workmanship! Hardwood Floor
Warranty & Brand – The value of your floor extends well beyond the floor itself. The people that created, tested, produced, and support it are just as important to consider. You want to make sure you are buying a floor from a manufacturer who you can trust. What kind of testing are they doing to make sure the floor you are buying will last? How can they help you if problems do occur down the road? What does the warranty actually cover? These are important factors to consider, especially when hardwood flooring doesn’t meet Rigid Core flooring’s abilities in areas like durability, dent resistance, and waterproofing. Hardwood Floor
"Click" or Woodloc systems: there are a number of patented "click" systems that now exist. These click systems are either "unilin" or "fiboloc" A "click" floor is similar to tongue-and-groove, but instead of fitting directly into the groove, the board must be angled or "tapped" in to make the curved or barbed tongue fit into the modified groove. No adhesive is used when installing a "click" floor, making board replacement easier. This system not only exists for engineered wood floors but also engineered bamboo and a small number of solid floors (such as "parador solido click") and is designed to be used for floating installations. It is beneficial for the Do-It-Yourself market. Denver Hardwood Flooring
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. Denver Hardwood Flooring
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.  Hardwood Floor
Not only is bamboo resistant to moisture, but it is environmentally friendly and an optimal choice for those who are looking to build “green.” The plant grows faster and does not take as long to re-grow than a typical hardwood tree, therefore not contributing to deforestation. Bamboo flooring is softer than traditional hardwoods, so it will not cause pain if it is stood on for long periods of time. The softness of the floor will also reduce noise. Denver Hardwood Flooring
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. Hardwood Floor
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. Hardwood Floor
