All the research says if you are going with Cabin Grade wood flooring you should purchase 15 - 20% extra for spoilage. If you purchase Cabin Grade from FloorMax you need to count on 30 - 40% spoilage. We purchased our flooring over a year ago with the understanding that we were building a new house and could not guarantee when we would be ready. When the first flooring came in it was not the color we had selected so we refused it. We took a sample box of another flooring home to see if it would match our decor...in the full box there was maybe 2 pieces that would not be suitable for installation. We went with this new flooring...big mistake. When we started opening boxes for installation, there was not a single box with less that 25 - 30% spoilage. FloorMax's repsonse....looks like Cabin grade, pull from more boxes. I have had 4 professionals look at the flooring and all four (totaling more that 100 years of experience) say it is the worst flooring they have ever seen. It is NOT even close to Cabin Grade, more like scrap. Don't get me started on the number of boards we found that had dead bees (yes BUGS) in them. At this point, we are stuck with the flooring and will have to make do....but take it from me YOU DO NOT WANT TO DO BUSINESS WITH FLOORMAX! PS: I am posting this review everywhere I can to help others from ending up with a nightmare floor like mine.
