Gapping wood floors

During the recent college basketball and NBA playoffs, one of the things that a lot of people have remarked to us about recently is the huge gaps in the wood floors of the various arenas.  They’re big enough to be noticed on TV, especially when the camera shows the free throw lane from above.  Depending on the court, there can be just one or two or several of them in that small area.  Most people are surprised to see them because from the distance that we watch most games on TV or even in the stands, the floors look absolutely tight and flawless.

Even floating floors using a clip system can show gaps from time to time, especially in drier seasons.  The concept of a floating floor is that the entire floor should shrink or expand as a unit and the gaps should only be around the outside of the flooring along the walls.  However, in especially dry periods, the boards may contract along the clip, creating slight gaps between each board.  This is not something that you should be concerned about – the gaps will close up when we come to a more humid time of the years.  In most floors, if you can slide a credit card between boards of the floor, you’re still okay.  It’s only when the gapping gets any wider, or if the gaps don’t close up in the summer, should you be a little concerned.

That might be a good time to drop us an email with pictures and let us take a look at whether this is something you should be concerned about.  Actually, you should feel free to email or call us any time that you have a concern about your floor.  But please take some pictures on your phone, showing the area that you’re concerned about so we will have a better idea of how best to get the situation fixed.

  1. Gapping in wooden floors is usual but they should not be very prominently visible. So, if you think that the gapping in the wooden floor of your home is drawing all the wrong attention, you might need to consult a specialist.

  2. Gaps in wood flooring are caused by the long-term expansion and contraction of the wood. Although significant gaps in relatively new wood flooring are relatively uncommon along the lengths of the board, you may find that newer floors develop gaps at the ends of the boards.
