2.5 year old townhouse near Washington DC
Living/Kitchen/Dining room approximately 18' X 36'
Hardwood flooring running in the 18' direction/perpendicular to the length of the room.
Every year in the Fall, the hardwood floor opens a gap nearly 1/4 inch across the room in the exact same spot.
This is "normal" seasonal change. The hardwood contractor states that this is common in homes.
They did finally agree to bring in a 3rd party inspector. I would like to have good, well thought out questions ready for them.
I am an engineer and their answer doesn't sit well with me.
I believe this is a subfloor issue.
I have had numerous homes with hardwood and I have never see an issue like this without other contributing factors (subloor problem, division between home addition, etc...)
Am I missing something? Could this be just a coincidence that it happens in this one spot and the builder is correct??
