They are private labeleing a product from Montebello or Monticello (can't remember what the label said?) anyway its milled in Virginia and finished in North Carolina. I have seen the product without the exdura name on the box and it is your typical lower middle of the road Oak. The milling is OK although the weird back relief profile is a little concerning. The finish is fair to Ok with quite a bit of open grain and some minor scratching out of the box. The lengths are not great at least in the 1200' floor we worked with it on, the average was under 2'.

You received bad information about the prefinish less likely to move. now they could have been referring to the engineered. but Solid prefinish is just as likely to move with a site finish floor. of course the movement will come from the environmental conditions in the home. Do prefinish floors has a tougher finish? yes, but it comes down to lifestyle. if you have a bunch of kids, large dogs, and throw partys every weekend, no finish will hold up for very long. But it sounds like you dont have the problem, so the toughness of the finish shouldnt be a huge factor for you. There are plenty of decent finishes on the market used by pros that for your situation should suit you just fine. I think the thing you should be looking at is price. Does the install of prefinish along with the price of the material work for your budget? or does the site finished work better? Site finish means the project will take a bit longer, because of the added time needed to sand and finish the floors. but those are minor. Have you found a pre finish product you like? In either case you should focus on sourcing a good professional and he will be able to answer the more detailed questions that are particular to your new home.

Not sure if you'll see this- we went this route with our floors. 4 1/4" prestige brushed. Not done laying it but I really like the tone of the color. Please disregard the construction zone.

That wood work in your home is to die for! Honestly, often part of the charm of older homes is the "evolution" of different types of hardwoods over time - are you completely opposed to sanding the existing hardwoods down and refinishing in the same stain? The ones in your pictures look to be in great shape and definitely fit the feel and age of your home. Could save you a lot of money and headache and end up looking great - just a thought. Whatever you do, please avoid putting in wide plank engineered wood floors (that are everywhere right now) - vintage hardwoods are incredible elements in older homes. Newer wood floors can zap the charm right out of an older home IMO.
