Does anyone have information on Reclaimed Redwood flooring? Any thoughts?

We want to install wood flooring over concrete.
My wife found an installer who specializes in reclaimed redwood from barns, fences, etc. He prepares it in his shop (hand selects, machines, pre-finishes with 6 coats of finish) then clues down and applies one coat of finish onsite. He says that the reclaimed aged wood is harder and more stable than new wood. He does not tongue and groove just full glue down.

He claims that it will actually be more harder and more durable than an engineered Brazilian hardwood floor since it is full depth instead of hard wood over ply.

I don't have any information on it and only doubt his "harder" claim in your last sentence.

Redwood is a softwood, and while it may be durable and stable, it will damage easily. But, on the otherhand, so is pine, and pine floors have been used for 100's of years, and a lot of people would love to have wide-plank old pine flooring. You have to decide what look is important to you. Maybe you love redwood, and the appeal of reclaimed barn wood is more important having a fancy hardwood. Some people like the look of "distressed" floors too and wouldn't be bothered by a few dings in a redwood floor.

I would insist on tongue and groove not only does it it ensure the boards are the same height( and stay that way) so you are not tripping over the lips on them but it locks them together. Your guy lost his credibility with me at the statement that redwood is harder. Maybe drier and more stable to humidity and moisture changes but not harder. I put down the softer woods on floors all the time. Here in East Tn. a popular choice is actually a yellow pine plank( with the tongue and groove )Over time the little dents give it a rustic character that is popular in cabins. Hope this helps
