I have a question for all you masonry guys. I had a downspout that got detached from the drainage line and the water seeped into the crawlspace. The crawlspace has a damp mildew smell. I have since fixed the downspout and everything looked good last rain. Now I was thinking about spraying all the walls down with raw bleach just to kill any mold that may try to grow and get rid of the smell. Is there anything that would be better????
