On a Hollywood 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 lowcountry and coastal plain ground
Two things work on framing near Hollywood: sustained humidity, and insects that damp timber attracts. It is common on the coastal plain to find decay and insect damage in the same joist, so a moisture repair here is inspected for both.
Flood-zone construction around Hollywood is built elevated, which means newer homes have crawl spaces too. Newer framing, the same conditions underneath.

Why it is worth dealing with now
Waiting is the expensive option here. Moisture that has been under a Hollywood floor for a year has already changed what the repair involves.
The full method and the step-by-step for this work is on the Crawl Space Wood and Subfloor Repair page, and how it behaves across the state is on the Wood and subfloor repair in South Carolina page.
Wood and subfloor repair in Hollywood: common questions
Why does the rim joist go first in Hollywood 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.
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.
My house is near Wadmalaw Sound. Does that change anything?
It can. Being close to Wadmalaw Sound usually means a higher water table and a longer wet season under the floor, so drainage and a properly sealed barrier matter more here than they would further from it.
Will my Hollywood crawl space dry out if I open the vents?
Usually not. For much of the year the air around Hollywood is warmer and wetter than the crawl space, so opening it up deposits moisture on the cool joists instead of carrying it away.
How quickly does water under a Hollywood house need to come out?
Quickly. Wood starts absorbing moisture immediately and mold can establish on damp material within roughly 24 to 48 hours. In Charleston County that window is shorter in summer than in winter, because the space stays warm and humid.
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.
