Solid hardwood is great for high traffic areas and rooms on the first or second floors where there’s limited moisture. You can purchase your solid hardwood floors either prefinished or unfinished. Prefinished hardwood floors have a coating that protects them and they’re ready to install right out of the box. Unfinished hardwoods allow you to apply your own stain color.
If your only goal is to brighten your floors and restore their original shine, consider refinishing them. But if you want to change some aspect of the floor itself, like the style of the wood, the direction of the planks or the consistency of the material, you will need to invest in a full replacement. Refinishing is ideal to restore existing wood, while replacement is ideal for establishing a completely new look or feel.
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. 
Although hardwood floors are amazingly beautiful and durable, they are not indestructible. The best floor maintenance plan for hardwood floors include regular vacuuming or sweeping with a soft bristle broom, especially in high traffic areas. Removing dirt or grit from your floors will reduce scratches. Vacuums with rotary brush heads can also scratch your floors. Denver Hardwood Floor – If you want to change the species of wood, you may consider replacing the hardwood. The majority of homes in the US have oak. Some people love the look and graining of oak; other customers prefer a more unique look – such as a brilliant Brazilian cherry or a clear maple or a modern looking bamboo. If this is the type of look you are going for, changing woods may make sense for you. But, please understand that you can stain your current floors a different color than they are now. So, don’t just make a change because you don’t like the color since that is easily changeable.
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. Denver Hardwood Flooring If you get a second opinion and they can’t be refinished, then your best option will be replace them…or wait until you can replace them. Given when the house was built I’m doubting the floors are even, so putting a floating on top will be a really bad option as they will wobble. And, installing wood on top of thin wood is a really bad solution. If your foundation is weak, your floor will be weak and it will creak and separate. Denver Hardwood Floor Install Judy – I’m sorry to hear this. I am surprised, but it does happen once in a while. I would probably get a 2nd opinion just to make sure. If they were solid hardwood and are now too thin, then it sounds like they’ve been refinished many times. Generally solid hardwood flooring is 3/4″ thick and that is what you should get if you put in anything new. That will then last a long time and you won’t have this issue in the future. Denver 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 Floor 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 Flooring This process involves treating the wood by boiling the log in water. After preparation, the wood is peeled by a blade starting from the outside of the log and working toward the center, thus creating a wood veneer. The veneer is then pressed flat with high pressure. This style of manufacturing tends to have problems with the wood cupping or curling back to its original shape. Rotary-peeled engineered hardwoods tend to have a plywood appearance in the grain.
