Document the condition first
Note where it appears, when, how it tracks with rain, and whether it's worsening. A couple of photos and rough measurements go a long way.
Read the local context
Asheville includes historic mountain neighborhoods, early suburban homes, bungalows, mid-century housing, and steep-site contemporary construction. Slope, intense rainfall, clay soils, retaining conditions, crawlspaces, and freeze-thaw exposure make the site inseparable from the house.
Ask what will be hidden
On sloped mountain lots, drainage has to be solved before anything else -- then standing water, liner attachment to uneven rock-influenced framing, termite-inspection access, air sealing, and equipment placement all follow. Have the provider document preparation and verification steps in writing -- once the barrier is in place, none of it stays visible.
Compare full proposals, not totals
Look at protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order terms.
What official local sources add
Asheville maintains flood-information and planning resources for a steep mountain city with active stormwater concerns. Parcel-specific slope, flood status, retaining conditions, and historic review can materially change both access and repair strategy.
