Friday we had a lot of rain and my sump pump died so I ended up with about 1" of water in our finished basement. I do have insurance just for sump pump failure so all is good right? WRONG!, The ins. sent out a crew today to start repairs, they pulled out the carpet and padding, then went to remove the lower 2' of the walls which are paneling over drywall. When the first pc of paneling came down, they found mold, it went 4' up the wall. Then they said that would not be covered under the ins. as it was an exisiting issue and had to be from old water damage. We have been here 7 yrs and this is the 1st time we had water. well then I called the ins. and they approved them to use an airscrubber to keep airborne spores to spread and go to 4' up the walls so they went further. They got to the next wall and started at 2' again to see if there was and mold, the paneling came down and there was no mold on the front of the drywall, a sigh of relief for my wife and I, but then when they pulled the drywall, there was mold on the back side. So it seems like all the walls have a 4' high issue. They are planning on pulling 4' off all the walls and remove all the paneling but say the studs, base seals, etc. may have mold. If they say the bill comes to s, we will have to do this ourselves as we cant afford to pay for it unless the ins. picks it up. How do I know it is gone and not going to be a issue again? I would like to replace all the drywall at this point and hope the ins. will pay for it, if not I am in deep crap...... I also have a sectional couch down there, there was a lot of concern abou spores spreading through the air, so they covered all the air ducts and put plastic up to isolate the basement, but if it spread onto the sectional, how do I clean that or is it junk?
