On a Startex job, crawl Space Wood and Subfloor Repair follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
The floor feels soft, bouncy or sloped, because the structure under it has been wet too long.
Wood and subfloor repair on piedmont and upstate ground
Around Startex the damage tends to arrive in steps, a little with each storm. Rim and band joist go first, because they sit at the top of the foundation where water running down the wall collects.
Piedmont clay is what this work is dealing with in Startex. Clay turns water away rather than absorbing it, so water arrives at the foundation from uphill and then sits against it for days.

Why it is worth dealing with now

Wood and subfloor repair in Startex: common questions
Why does the rim joist go first in Startex homes?
Because of where it sits. It runs around the top of the foundation, where moisture from the wall and poor exterior drainage concentrate, and it is usually covered by insulation that holds that moisture against it.
Should repairs wait until the space is dry?
Yes. New timber fitted into a damp Startex crawl space starts absorbing moisture the day it goes in, and the repair becomes a return visit instead of a fix.
Is the damage sudden or gradual here?
Gradual, mostly. Around Startex it arrives in steps — a little with each storm — so by the time a floor feels soft upstairs the framing has usually been damp for a while.
My house is on a slope. Does that make it worse?
Usually. Water landing uphill of a Startex house travels along the clay to the foundation, so intercepting it uphill often does more than extra pump capacity underneath.
Why does my Startex crawl space stay wet for days after the rain stops?
Piedmont clay. Around Startex, at roughly 794 feet, the ground holds water against the foundation long after the surface looks dry.
Can a rotted joist be repaired, or does it need replacing?
Both are used. Where a member has lost some capacity but is sound at its bearings, sistering new timber alongside it is often appropriate. Where the end has decayed where it bears, or the loss is extensive, that section needs replacing. The inspection decides, not a preference.
