I bought a house a few months ago and the basement was basically finished. So I am redoing the bathroom and so I rip out some drywall along the exterior block foundation wall. And noticed the 2 x 4 framing is basically up against the foundation wall, and it has faced insulation between the studs.
All I have read is to put the foam board on the foundation wall then frame etc. Well this wasn't done that way. And I had no plans of ripping everything out and starting from scratch and basically I can not at all afford to do it.
I haven't had any moisture problems, ran a few tests and they came back negative. The foundation wall is painted so maybe that's acting as somewhat of a moisture barrier and then the tabs on the paper backed insulation are acting as a vapor barrier? is that possible?
I guess I am curious what my options are, short of ripping everything out? I did notice the paper on the insulation was a tad dark, either from just time or maybe there is a little moisture. but the insulation itself looked good. Do I have options, I may even go as far as ripping the drywall off if I have options. Any advice would be great, and thanks in advance
