Taken on its own, crawl Space Wood and Subfloor Repair treats one part of the problem. Taken in order, it is the part that makes the rest hold. That is how we schedule it on Centenary jobs.
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 Centenary: 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 Centenary 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.

What the work involves
What we do on a Centenary job of this kind:
- Floor structure inspection with moisture readings recorded
- Temporary support while members are repaired
- Sistering, splicing or replacement of affected joists and girders
- Rim and band joist replacement where decayed
Why it is worth dealing with now
Nothing about a damp Centenary crawl space improves on its own. The space is enclosed, shaded and over soil — all three work against it drying out.
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 Centenary: common questions
Should repairs wait until the space is dry?
Yes. New timber fitted into a damp Centenary 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.
Why is my Centenary crawl space wet when nothing has leaked?
Near Centenary that is the normal pattern rather than the exception. At around 56 feet on the coastal plain, the water table sits close enough to the surface that soil under the house can be saturated with no pipe broken.
How quickly does water under a Centenary 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 Marion County that window is shorter in summer than in winter, because the space stays warm and humid.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Centenary 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.
Is bouncy flooring always a crawl space problem?
Not always — it can be span, joist spacing or subfloor thickness from the original construction. But where it is new, localized, or paired with a musty smell or a damp space below, the cause is usually moisture damage to the structure underneath.
