Two small areas of the wood floors in my living room and den got water damaged due to overwatered plants that were sitting on top of them. They were in pots on top of a base and felt covering but the water seeped through anyway. One panel of the wood on the floor around the fireplace has expanded. There are dark brown stains and rings where there used to a nice wooden floor. Is there any way to fix these areas without redoing the entire living room and den floors?.
