Am trying to find out what to do to eradicate the smell under the house. It was probably caused by an undiscovered leak in the shower, which has been fixed. A year ago, I choroxed the entire underneath of the house (on the wood) but the smell is still there. There is a vapor barrier, and no further leaks have been detected. Any solutions? De-humidifiers? More chloroxing? Scrubbing? Any commercial product? More ventilation -- already to code?
