Semi-conditioned New Build Crawlspace
I recently moved into a new construction single family home on a crawlspace in upstate SC. The builder put in a loose vapor barrier, sealed the vents with foam, and installed a dehumidifier. While it may be “sealed” there is still plenty of places for air to get in either through the door or between the foundation and wood framing. I recently started tracking the humidity and it hovers around 65% depending on the day and the dehumidifier is always running. My question is do I need to have this space resealed to lower the humidity or is 65% OK? Most of what I have read says 50-55%.
