I recently had a gray water leak in my crawlspace. There are 2 areas approx. 5’x5′ and the ground is saturated to a depth of 12 inches. We noticed a strong mildew aroma in the house. The pipe has consequently been repaired and I am using fans to attempt to dry up the wet spots. What product or procedure do you reccomend that I do next as the smell is still apparent. Let me know.
If you are smelling the mildew up in the living area, there could very well be some mold growth on the structure. At this time I would recommend doing a good inspection of the wood inside the crawl space to make sure there isn’t a lot of mold growing. If there is, you’ll need to treat it with the MOLD BLASTER listed in our MOLD CONTROL ARTICLE. This will promptly kill off any that’s growing and it should last long enough to prevent further mold from appearing.
I have seen cases where the dirt itself can maintain the mold growth and be releasing the odor. In these situations it can be a bit harder to treat since there isn’t a specific location where the mold is growing so in most cases, treating over the entire area is the best way to proceed. Soil or dirt which has a lot of organic matter is capable of generating a lot of smells. When this organic matter gets ample amount of moisture there will be a chain of events that kick into action with the end result being some type of odor. If you suspect it’s the soil that smells, treat it with the NNZ listed in our ODOR CONTROL ARTICLE. Depending on how long it takes for the water to dry up, you may have to apply the NNZ a few times to keep the odor minimized. In the end you should be able to keep it thwarted through a combination of little to no water in the area along with the NNZ.
