Need to replace or repair a single hardwood floor board? Don't want to pay people hundreds of dollars to do it? Well, if you have a circular saw and a straightedge. Then you can do-it-yourself by following this video. First of all, remove the old board by cutting a section of it using the saw and prying it out with the straightedge. Then, get your new floor board, which should be retrofitted, then apply some adhesive and fit the board back into the spot where the old board was. Hammer the new board in with a rubber mallet and place some weight on the board and leave it overnight. You have just removed and replaced your very first hardwood floor board.
