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 Saint Helena Island jobs.
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 Saint Helena Island 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 Saint Helena Island 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.

Why it is worth dealing with now
The cost of this work does not stay flat. Every season a Saint Helena Island crawl space stays wet moves more of the job from drying towards framing repair.

Wood and subfloor repair in Saint Helena Island: common questions
Why does the rim joist go first in Saint Helena Island 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.
Is the damage sudden or gradual here?
Gradual, mostly. Around Saint Helena Island 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 Saint Helena Island house travels along the clay to the foundation, so intercepting it uphill often does more than extra pump capacity underneath.
Why does my Saint Helena Island crawl space stay wet for days after the rain stops?
Piedmont clay. Around Saint Helena Island, at roughly low feet, the ground holds water against the foundation long after the surface looks dry.
Should repairs happen before or after drying?
After. New material fitted into a crawl space that is still wet, or whose water source has not been corrected, begins taking on moisture immediately. Drying and source correction first is what makes the repair last.
