Had solid oak floors fitted about 3 months ago. I'm just not sure if they did a very good job. There are gaps between some boards and it looks like they actually put some wood filler between them in places. Also, some boards are slightly raised relative to others. There are also some bad choices in terms of boards used beside each other but I can live with that. The above problems are not very severe - they are really only noticeable to people like us who are down on floor with kids all the time but I like to know if its likely to cause problems down the line. Thanks.
