ok, this is an area where I actually know something! I sold and spec'ed hardwood for a custom shop before my mommy-life. The information you are getting here is correct. Engineered floors will give you 1-2 refinishings ON A PERFECT SUBFLOOR. One of the issues that sometimes arises if there are inconsistanies in the height of your subfloor. Because there is thinner wood wearlayer (before you get to the engineered wood) there is the chance that you can damage the floor irreparably when you sand it. Now I only saw this saw this happen twice, once on a loft job and once in an older home. The loft was more subtle as it was over concrete, the old house more obvious as they were DIYers and picked engineered flooring to try to negate their irregular subfloor (they neglected to tell us that that was why they chose engineered, we would have talked them out of it had we seen the floor first) Neither of their claims to the manufacturer were fully settled because both times they did not follow the guidelines for floor prep. The loft job was also a materials only job for us with their GC laying the floors but he insisted he knew what he was doing. A good engineered floor will not be cheaper than most of your nail down options because the production costs are higher. Now having said that, GOOD engineered floors certainly have their place in places where you can't put traditional hardwood due to height restrictions or concrete subfloors. My boss had a great engineered floor in his basement and it survived a flood remarkably well (it was ash, Kahrs brand out of Scandinavia and one of the beefier engineered floors and one of the pioneers) My Grandmother also had a Kahrs floor in her ground suite condo and she LOVED it and I was impressed by the milling. I'm considering it for our basement because it's warmer and less echo-y than laminate There has been a lot of 2nd rate engineered flooring coming out of China and being labeled for all sorts of different companies. You should be able to tell an engineered sample because the layers are sandwiched together and the tongue will be a different wood than the top (showing) layer. Distressed finishes are usually more expensive because of the extra step in manufacturing to make it distressed. That is different than just getting a lower grade of hardwood like a rustic or tavern grade (in solid hardwood). Those grades have more character but they often don't carry a warranty and generally have a higher waste percentage. Another thing to think about---if you ever have to replace part of the floor, you will always be able to replicate 3/4" thick hardwood but engineered floors are more like tile, they change and get discontinued over the years. You could go pre-finished, save the hassle of site finishing but with the thicker wear-layer a 3/4" nail down floor offers. Only you will know if you can handle beveling or not. The changes in milling the last 10 years are huge. The bevel in your better milled wood is tiny. I like Canadian mills, Model or Mirage for pre-finished. Remember that if you ever re-finish, the bevel will disappear and you will, essentially have a site finished floor. One benefit that many people don't know about? With a prefinished tongue and grooved floor you can have a good installer cut out a single board (or more) from your floor if it gets damaged which is why we did a fair bit of pre-finished in new homes since inevitably we would get call-backs at move in to repair trade damage (@#$%^ plumbers and their big wrenches!). Prefinished hardwood deals the best with shinkage and expansion issues because the finish is on individual boards. Site finished floors are more labor intensive but the materials are cheaper (apples to apples). They are what many people consider the gold standard however there are more steps and you don't always know how it's going to look until it's done. There is more chance of finish contamination and trade damage during the rest of the building process. We refinished 100 year old floors. I loved the idea that there wasn't 4 generations of carpet and crap in the landfill. Definitely a forever floor and it can usually be re-sanded for all but the very worst water damage (think entire house under water for a few days) If you are going with a wide plank, keep in mind your species and humidity level (and your ability to keep humidity stable). The wider the plank (with 3/4" thick flooring), the more obvious shrinking and expanding will be. If you take a 2" wide board and it shrinks 2%, it isn't very noticeable. If you take a 6" wide board and it shrinks 2% the gaping will be more noticeable and in the case of a site finished floor *could* pull your finish apart. You'll need to find a flooring contractor in your area with lots of experience. Most of the best hardwood shops ONLY do hardwood. Beware of carpet shops and many of the big box stores in many instances. Make sure they are accredited with the NWFA (national wood flooring association) http://www.nwfa.org/member/ good luck!

Wow...that's a huge question. I know it sounds simple, but it is quite complex. So complex there are entire books on the subject (both professional and lay-man). So....solid hardwood is just that. It is solid. It is the same wood cut from the same tree, from the same plank at the mill. Traditionally it is 3/4" thick. Widths vary but the classic is around 3" wide plank. A 3/4" solid hardwood can be refinish 3-4 times with a total lifespan of 60-100 years. These are either factory finished or site finished. The industry has realized that some people are too afraid of large purchases so the solid hardwood industry has come up with the idea to make their planks THINNER and thereby making them cheaper. I've seen 1/2" or even 3/8" solid hardwood. They can be refinished once...maybe twice and have a lifespan of 20 - 40 years. These thinner solid hardwoods are often factory finished (cheap, thin and fast). And that's the easy part. Engineered hardwood...where to start. First off the TOP layer is the ONLY LAYER that contains the pricey hardwood that you are paying for. Everything else is like "plywood". The body of the plank is made up of cross-hatched layers of wood (not always hardwood) that are glued together. The top layer will range from 2mm - 6mm. The ability to refinish will depend on the thickness of the top layer (known as the wear layer). You need 3mm of wood to complete a full sand and refinish - just once. So the 2mm wear layer is a "one and done" type of floor. It has a life span of roughly 20 years (though many people rip them out after 15 because they look beaten up). The 6mm wear layer in a 3/4" engineered plank that is site finished is the Holy Grail of the engineered hardwood world. They are the most expensive, the most beautiful and offer the longest life cycle of all engineered hardwoods. They are so expensive that they are MORE expensive than solid hardwood floors. Whew. There is so much more but that's the difference in a nutshell. Shaw has had some complaints. The biggest issues with wood will be humidity and indoor climate control. Ask your builder to check the heating/cooling system. Ask them detailed questions about the unit's capability to handle climate control that is REQUIRED for a hardwood floor - regardless of the presentation.

I'm a fan of Hickory. Love it! I love it's STRONG variation! Yep. Variation is the word that can be used for Hickory. If you are going for "mid-tone" then it means the Hickory is stained. No problem. That's fine. Hickory takes a stain very nicely. But it will still have plenty of variation. The stain will even that out a little bit, but not entirely. The finish is UV cured urethane. I'm not very excited about that finish. If you are going for factory finish, you will want to work with the TOUGHEST finishes on the market (that's why you go with factory finished...for the TOUGH finish). The UV cured urethane is a ho-hum type of finish. Average would be the best way to describe it. The thickness of the plank is 3/4" = normal for sold. The plank width is 5" with random lengths UPTO 60" (5ft). That tells me there will be many planks in the 3' - 4' range. Again, this is ho-hum average. And with a wide plank product, it will need "glue assist". And Hickory certainly needs it because it has a bit more movement (less stable) than white oak. And then there is the "low gloss" format. The low-gloss finish on this depth of colour = nightmare to live with. It will show dust, etc as well as oily foot prints, sock prints, paw prints and will look hazy at certain times during the day. The "haze" is part of the chemical make up of the finish itself = that's how they take away the gloss...they haze it with a chemical additive. The haze goes away when you sand and refinish the floor. That's the only way to fix it. If you must have a mid-tone floor, I would recommend a TOUGHER finish (aluminum oxide or ceramic infused polyurethane) in a satin. Satin is FAR MORE livable. It offers a lovely glow without being shiny. It hides skin oils (like paw prints from dogs) because it is the same gloss level as skin oils....it isn't hazy....you get the idea.

Go for it. I would throw down some 3mm or 6mm cork underlay down (it floats just like the hardwood) and then float the hardwood. Use a high-quality joint glue on the hardwood and you should be fine. Besides...if it gives up the ghost in 10 years, would you be upset?
