Reasons for hardwood boards separating?
The oak hardwood floors in our 1950's house were refinished less than a year ago. When we moved in six months ago they were smooth and looked new. Since then, some of the boards have started to separate, some as much as 1/8". Does anyone know what could cause this? It has rained a lot so I am wondering if it is from moisture or even a foundation problem. I would like to find the solution and stop it from separating further.
