BUYER BE WARE.
It's not good for the consumer when the only REAL warranty they have is direct from the manufacturer. Read the back of your contract they basically will hardly cover much of anything and that means they can sell you junk and the tell you bug off and deal only manufacturer and for hardwood floors not much different they can butcher your cabinets and moldings and not be held responsible for anything even IF they tell you they have certified professional installers.
