We just had installed oak hardwood flooring in the house just bought. The whole thing was in a big rush because we had to move in in a short period of time. Now after the "dust" settled, when we look at the new floor we see that it is not perfectly installed. Some pieces of wood (don't know how they are called) (they are in length of about 36 inch and wide 4.5 and one edge of it enters in the edge of the piece near it) do not fit exactly near the next ones. Some gaps of 1/8 of an inch makes our new floor not to look very nice. There is any remedy to fix it? Like to push the wood forcefully to fit properly? I imagine that if the culprit is in the middle of the room I have to move all of them to the end of the room. Any suggestions greatly appreciated. Thank you.
