1. Observe and protect
Record what's happening and since when, avoid steps that could mask the real cause, and gather any prior repair records.
2. Evaluate the house and site
Encapsulation planning should address drainage, standing water, termite-inspection access, liner attachment, air sealing, equipment placement, and the existing condition of wood framing -- especially on East Tennessee's sloped, karst-influenced lots, where a crawl space can trap more moisture than it would on flat ground.
3. Define a written scope
Get preparation, protective measures, specific materials, access needs, permits, testing, cleanup, restoration, exclusions, and change-order terms spelled out.
4. Compare providers
Check credentials, then compare the reasoning and boundaries in each proposal -- the karst terrain often means the cheapest bid skips drainage work.
5. Inspect closeout
Before signing off, confirm testing, cleanup, documentation, warranty terms, and any maintenance that's now your responsibility.
