re: subfloor and floor replacement

Can’t help on the ventilation issue, and you’ll want to take care of that first. Once your new subfloors are in, if you want to go with closed cell, give Barry at Quality Spray Foam a call. He’s out of Houma but will come to NOLA for a job. He’s a good guy and he’s fair. 980.870.2276.

Also, if you do go with closed cell, it’d best to wait until the winter when humidity levels are down, as the moisture content of the wood will be lower then.
