OK, walking away isn't an option for this new owner. I live in a high water table area. During recent heavy rains, I had several inches of water in my crawl space and standing water in the yard is within several feet of my crawl space. Previous owners have built up elevated flower planters with railroad ties around the perimeter of my house. Can I improve drainage away from the house and maybe resolve this water in the craw space problem by removing the railroad ties and regrading the soil so it slopes away from the house? Also, what do I do with the moisture build up? Will it cause mould...should I have the crawl space disinfected? Hindsight tells me those water stains I saw in the crawlspace prove this isn't the first time this has happened. Are there other potential problems? Panic follows.
