How long does it take to put in flooring?

That all depends on the type of flooring being installed, what has to be removed from the floor if needed, if the floor has to be totally replaced before the new flooring is added. With just these variables it can take from less than a day to 3 days with a skilled person with a team doing the work. Can take a week or more with someone working alone or less experience. Mainly depends on what needs to be done.
