Pulled up the damp bedroom rug and found mold in an area about 2' square near the slider. The subfloor is fairly saturated and the mold remediation guy says the subfloor needs to come out and some of the drywall ripped out to see if mold is behind the wall. He found no evidence of mold in the crawlspace. Then he says we need to scrub the air, get rid of the entire bedroom carpet,treat the mold with chemicals and have a contractor do the put-back work since all they do is the take out work. I know first of all I have to stop the source of the water, but how about the rest of it, does it sound reasonable?
Thanks for any input or opinions.

 

Mold remediation for 2 sq ft??? No. that does not sound reasonable. Unless the floor is rotton, it does not need to be replaced. Scrubing the air is a joke, since *all* air contains mold spores.

Provided you kill the mold, and scrub it clean, then stop the source of the leak, your mold will not grow back. Mold will only grow in areas where the relative humidity is constantly 60% or higher.

If the source of the leak is taken care of, I wouldn't even check inside the wall. But that's just me.
