Our kitchen sink pipes broke. The pipes are fixable; however, I have no idea what's happening between the bottom of the sink and the floor. I'm not a carpenter and would prefer not to hire someone to remove the sink floor for $$ sake. Is there something I can spray/pipe between the cracks into the under the sink and floor? Is there some anti mildew foam or spray with a long plastick hose to fit in hard to reach areas that could be used?
Thanks in advance.
