On a Una 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 Una 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.
Around Una the damage tends to accumulate in steps, a little with each storm, rather than arriving all at once. By the time it is noticed upstairs it has usually been building for a while.

Wood and subfloor repair in Una: common questions
Can a rotted joist be repaired rather than replaced?
Both are used. Where a member has lost some strength but is sound where it bears, sistering alongside it is appropriate. Where the end has decayed at the bearing, that section is replaced. The inspection decides.
Why does the rim joist go first in Una 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.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Una call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Do you work outside Una itself?
Yes. We cover Spartanburg County broadly, including Arcadia, Fairforest and Spartanburg, and the rest of the Piedmont and Upstate of South Carolina.
Is crawl space water damage covered by insurance?
It depends on the cause, not the address. A burst pipe in a Una home is commonly covered; groundwater, long-term seepage and flooding usually are not, and flood damage generally needs separate cover. Photograph everything first.
Why does the rim joist rot before anything else?
Because of where it sits. The rim or band joist runs around the top of the foundation, where moisture from the wall, the sill and poor exterior drainage all concentrate, and it is frequently covered by insulation that holds that moisture against it.
