Crawl spaces around Seneca

Lake homes are some of the hardest crawl spaces in the Upstate. Two big lakes keep the air heavy with moisture most of the year, and many houses are built into hillsides where the uphill side of the crawl space stays wet. Seasonal and weekend homes add another problem: nobody is there to notice the musty smell until mold has taken hold.

What we commonly find in Seneca

  • Lake Keowee and Lake Hartwell homes on steep lots
  • Second homes that sit closed up for weeks at a time
  • Crawl spaces that need a French drain before they can be sealed
