You had a water leak in your crawlspace. How did you find it? From the odor probably. There is nothing like the smell of a wet, damp, musty crawlspace, right? What’s not to like?
Let’s see, there’s possibly mold. Could be a dead animal or two. How about excrement from any animals that may still be alive? How about a little bit of sewage? And to top it all off, you get to lie down and crawl around down there. Oh, we forgot, there are probably no power outlets so that means no lights. Did I mention there might be snakes and spiders?
Will your insurance companies really pay to dry dirt?
They most definitely will if your loss is a covered peril!
1. Soil is highly porous. It will accept and release moisture very quickly. Too high a rate of evaporation and you will force the excess moisture out of the dirt and into your structural materials: beams, floor joists, subfloor components, etc.
2. There is usually a moisture barrier present. Poly sheeting that will trap water under it, especially if it was installed wrong or is in disrepair due to age or some of those afore mentioned critters that may have been living down there.
3. Structural materials and concrete have bound water in them. This moisture is hard to remove and requires a higher evaporation potential and lots of air flow.
4. Entry is usually restricted, just a small opening through which to enter the crawl space. If the entry point is not put under containment, a stack effect, the natural rise of air through a building, will allow the air in the crawlspace to move up into the living area. And that’s the last thing you need.
