We will tell you if crawl Space Wood and Subfloor Repair is not what your Gable crawl space actually needs. Doing this stage out of order is the most common reason the work has to be repeated.
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 Gable: 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.
In Gable the complication is the water table. It sits close enough to the surface that soil under a house can be saturated with nothing broken, so this work is usually dealing with moisture arriving from below rather than from a failure inside the house.

Why it is worth dealing with now
A crawl space problem in Gable is not self-limiting. The conditions that created it are still there, and they are still working.
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 Gable: common questions
Should repairs wait until the space is dry?
Yes. New timber fitted into a damp Gable crawl space starts absorbing moisture the day it goes in, and the repair becomes a return visit instead of a fix.
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.
Can I stay in the house while the work is done?
In almost all cases, yes. The work happens under the floor, and access is usually through an exterior hatch. We will tell you up front if anything about your Gable property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Gable 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 Gable itself?
Yes. We cover Sumter County broadly, including Sardinia, New Zion and Turbeville, and the rest of the Lowcountry and coastal plain of South Carolina.
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.
