Supplemental Beams & Jacks in Sea Island, GA
Sea Island floors, quiet and firm again.
A soft spot in a fine home usually means a post or beam under the floor is failing. New steel support brings it back, and our crews work clean and out of sight.

Why Sea Island homes need this, and how we do it
Sea Island homes sit on dune sand, and salt aerosol off the water works on the crawl space year after year. It corrodes hardware, rusts the straps and hangers, and keeps the wood damp enough to soften a post at its base. Many of these houses are lived in part of the year, so a floor can go soft slowly while no one is walking on it every day.
The repair is steel and it is quiet. We set new adjustable jack posts on fresh concrete footings, then run a supplemental steel or engineered beam under the long joist runs so the load spreads the way it should. Corroded hardware and any rotted post or girder gets swapped out. The lift comes up slow so nothing cracks in the rooms above.
You get back a floor that holds still under a full room of guests and a crawl space that is drier than it was. On a high-value home we schedule around you, keep the site tidy, and hand you a written report so you know exactly what we found and what we did.
What’s included
The whole load path - not just the soft spot
Every supplemental beams & jacks we do in Sea Island, 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

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 Sea Island homeowners ask us
We only stay at our Sea Island place part of the year, could a floor problem be hiding while we're gone?
Yes, soft floors often creep up quietly in homes that sit empty part of the year, especially with the salt air working on the supports. We do a free inspection with a written report and, if needed, set steel jacks on concrete footings and a beam underneath to steady things.
The floors in our luxury home feel a little soft in spots, is that normal for a house this nice?
Even the finest homes get soft spots when a support post rots or a span sags underneath. We slip in from the crawlspace, set adjustable steel jacks on poured footings, and add a supplemental beam so the floor feels firm again, typically in a day.
I'm worried the salt corroded the metal supports under our house, can that happen here?
It can, coastal salt corrodes hardware and eats at supports over the years on Sea Island. We check it all during a free inspection and replace anything failing with steel jacks on concrete footings plus a beam to carry the load.
Can you fix a soft floor without me having to notice any mess in the main living areas?
For sure, this work stays down in the crawlspace, so your finished rooms are untouched. We set steel jacks on footings and a supplemental beam under the soft area and are usually done in one day.
How do I even know if my part-time home has a floor support issue building up?
The tell is a floor that gives a little underfoot or a spot that feels different than the rest, and a free written inspection will confirm it. If we find a rotted post or weak span, we set steel jacks on footings and a beam to bring it back solid.
“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.”
