What causes most Gatlinburg crawl space problems
The dominant failure mode locally is slope creep and colluvial movement on steep building sites. A second, less obvious pattern also shows up here: surface and subsurface water routed downhill through crawl spaces.
Because bedrock in this area is shallow on slopes, deep in colluvial hollows, two houses on the same street can need very different repairs for identical symptoms upstairs. That is the single biggest reason to get an independent structural opinion before accepting a contractor's diagnosis.

Gatlinburg crawl space questions
Why do crawl spaces in Gatlinburg have problems?
Slope creep and colluvial movement on steep building sites. Locally this sits on metamorphic and clastic rock — gneiss, schist, sandstone, with colluvium and stony loam on steep slopes above it.
Is my Gatlinburg home likely to have a crawl space or a slab?
Stepped crawl space and daylight basement on slopes.
How bad is crawl space moisture in Sevier County?
Very high on hillside sites. Tennessee summer dew points stay high enough for months that vented crawl spaces condense moisture on cool surfaces.
Do I need to worry about sinkholes in Gatlinburg?
None — non-carbonate terrain.
