Wet basement OSB in new build
Building a tract home in Syracuse NY. House has tyvek but no siding yet (a week to 10 days away). Upstairs is at the drywall mud stage. Basement is at the FG insulation stage. For about a week and a half the house was heated with a salamander propane heater which dumped a lot of humidity into the house. Plus the humidity from the mud. That heater is now replaced with a temporary furnace that is exhausted outside.
Anyway, the basement exterior wall cavities are 2x6s with an osb exterior. It has been very cold here (-9 on friday morning) and with the very humid interior air … of course I have condensation on the osb. It doesnt seem moldy but it’s wet.
I took it upon myself to pull all the FG out of the cavities this afternoon because I assume that it would be preferable to let it dry out a little bit before sheet rock goes up. The interior humidity is dropping and the exterior temps are going to be a more typical teens to 30s.
Here’s my question … am I over reacting? Should I have just left it alone and let it dry out over time? When would it be safe to re-install the FG? Maybe right before the SR goes up? Bear in mind that this is not a custom build and my builder will likely be pissed that I engaged in some self help. He’s likely to tell me that they do this all the time and that it will be fine. Any advice would be appreciated.
