My apartment had a leak back in June that did enough water damage to the wood flooring that we had to replace some of the wood. We hired a flooring guy to come in and replace the damaged wood and refinish the entire room so it all looked uniform. Fast forward 9 months and the new hardwood flooring looks like its splintering along the edges. Does anyone know why this happens or how to deal with it?
Here are some pics to help illustrate the issue:
Here is a picture of the flooring that was NOT replaced. You can see that there is a negligible gap between the boards:
