We pulled out a large section of the floor and all the insulation where we found the rot and replaced it with PT plywood and new insulation this past weekend. I have been running a small dehumidifier 3-5 days of each week since I noticed the smell. I also did two bleach cleaner wipe down of all surfaces this past month and I am happy to report that when I enter The Adjuster now..... No mildew smell! Now to decide what flooring to plan for. Continuing to move forward very slowly, but moving forward regardless!
