Why White Oak homes need this, and how we do it
White Oak is a timber-country crossroads on US-17 in northern Camden County, where the Satilla River runs through sandy loam ridges dotted with cypress-swamp pockets. The homes sit far apart down long drives, most of them on their original piers over open dirt. Builders out here ran long joist spans on wood posts set straight on the ground, and the base of those posts rots where the soil stays damp, so the floor sags and turns springy in the middle of a room.
We firm it up with new steel. Adjustable jack posts go in on concrete footings so they bear on solid ground below the open dirt, and a supplemental steel or engineered beam takes over the long spans the wood girders were holding alone. Rotted posts and girder sections come out and get replaced. The lift is slow and controlled so the finishes above ride it out fine.
Once the steel is in the sag stops and the floor holds firm across every span. Because the bare sandy-loam ground and the nearby swamp keep these crawl spaces damp, we usually talk through covering and drying the space, so the new supports are kept up off the wet dirt that rotted the posts they replaced.
What’s included
The whole load path - not just the soft spot
Every supplemental beams & jacks we do in White Oak, GA follows the same checklist. We support the framing that failed and the framing that is about to. A typical beam and jack scope includes:
- Elevation readings across the floor to find the real low point
- New poured concrete footings sized to the load and the soil
- Adjustable steel jacks set plumb and shimmed to bear evenly
- Supplemental beam under long or undersized joist spans
- Rotted or split posts, girders and joists replaced or sistered
- A slow, staged lift so plaster, tile and trim are not shocked
- Photo documentation before, during and after
What we won’t do
We will not stack blocks or shim on bare dirt, we will not crank a jack fast enough to crack your ceilings, and we will not put new steel under wet, rotting framing without telling you the moisture has to be dealt with as well.

Questions White Oak homeowners ask us
Out here off the Satilla in White Oak my posts are rotted at the base, is my floor at risk?
Yes, when posts rot at the base they stop holding, and the floor above starts to give and sag. We replace them with steel jacks on poured concrete footings and add a beam where the span needs it, working from underneath.
My rural home has posts sitting in open dirt, why are they rotting?
Posts in open dirt near the Satilla stay damp and rot from the ground up, which weakens your floor support. We set new steel jacks on concrete footings that handle the damp far better, plus a supplemental beam.
The floor over my crawlspace sags where a post gave out, can you lift it?
We can, we set an adjustable steel jack on a new concrete footing right at the failed post and add a beam if the span needs it. That lifts and holds the sag, usually a one-day job from below.
Can you get under a rural White Oak home to replace rotted posts?
Definitely, the open dirt crawlspace gives our crew room to set steel jacks on footings and a supplemental beam. Most repairs out here wrap up in a single day.
Is a rotted post something that spreads to the rest of the floor?
It can, because once one post fails the neighboring supports carry more and can start to give too. We'll catch it with a free written inspection and set steel jacks on footings and a beam before it spreads.
“Our floors had gotten soft and the whole downstairs smelled musty. They inspected the crawl space, showed us photos of the rot and moisture, and fully encapsulated it. The smell is gone, the floors feel solid, and our humidity finally stays under control.”
