There our no national standards that require flooring contractors to remove any stains, discoloration or damage from your floors. There are also no standards that specify the flooring finish should last any specific amount of time. There is no state required testing for wood flooring contactors.
The national standards for wood flooring states they should be inspected from a height of approximately five feet directly above the floor and under normal ambient lighting. Light from a bank of windows, doors, canister light or spot lights are not considered normal ambient lighting. Wood floors are allowed to have some finish defects from the contactor but may not be prevalent through out the room.
Why use a Nationally Certified Professional?
The wood flooring professionals certified through the National Wood Flooring Association Certified Professionals program have proven their expertise. They have undergone a series of vigorous exams, both hands-on and written, to prove both their knowledge and skills.
