I was preparing to sell a vacant house when one day I arrived to find 4 inches of water from a rusted out hot water tank, which had probably sat for about 4 days. The basement didn’t smell that good before as there was always a humidity problem, and this made it really bad. I did not wish to invest a lot of money in a house that I was not keeping, yet I wanted it to be sanitary and odor free for the buyer. The mold bomb did a fantastic job! The basement smells fresh and clean, no double better than it has in years!
