If you've ever seen a hardwood floor board replaced in the middle of the floor by a professional, you were probably amazed at how good it looked. We're going to show you the technique they use so you can achieve the same results.  

 

 
Step 1.  First determine whether the board to be replaced is split or just surface damaged. If the board is split, as in the picture, use a chisel to cut out from the center toward one side as shown. If the board is not split, use a circular saw (with depth gauge set at 3/4") to make a series of parallel cuts 1/8" apart through the entire length of the board. Stop sawing about 1/2" from each end of the board to be replaced, and 1/2" from each side. Drill a row of holes across the board at each end where the saw cuts stopped.

 

Step 2. Chisel out the center section of the board where the saw cuts and drilled holes are located. Chisel out the remaining 1/2" of wood at each end carefully so as to not damage the adjoining piece.  The end of T&G flooring has tongues and grooves just like the sides do.  You don't want to damage these.  When you are replacing more than one board, pry out the remaining damaged boards using this open area. 

 
 

Step 3. Last, Install new hardwood flooring and nail diagonally through the tongue, following standard installation techniques. The last board installed must be modified by cutting off the lower part of the groove so the board can be slipped into place as shown in the drawing.  Drill pilot holes and face nail this board, countersinking the nails.  Putty the holes and you're done!
