Supplemental Beams & Jacks in Jekyll Island, GA
Jekyll Island floors, firm on every pier.
On an elevated pier home one soft pier can put a dip in a whole room. New steel jacks and a supplemental beam pick the load back up.
Supplemental Beams & Jacks in Jekyll Island
Why Jekyll Island homes need this, and how we do it
Jekyll homes are mostly elevated on piers with open crawl spaces underneath, and those spaces stay damp all year. Wood posts sitting in that air rot at the base, the metal hardware rusts, and one pier at a time starts to go soft and lose its bearing. When a pier drops, the floor above it dips and the joists near it begin to flex.
We restore each pier line with steel. Adjustable jack posts go in on solid concrete footings, and where the joists run long we add a supplemental steel or engineered beam so the floor is carried evenly across new steel support. Rotted posts and rusted connectors get replaced, and the lift is brought up slow so nothing above cracks.
Once the piers are firm again the room stops dipping and the bounce is gone. Because the open damp crawl is what softened the last supports, we usually recommend drying and sealing it so the new steel and the wood around it stay sound in the island air.
What’s included
The whole load path - not just the soft spot
Every supplemental beams & jacks we do in Jekyll 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
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 Jekyll Island homeowners ask us
Our Jekyll place is up on piers and the crawlspace stays damp, is that hurting the posts?
Damp crawlspaces on Jekyll rot the wood posts and rust the hardware over time, which weakens your floor support. We swap in steel jacks on concrete footings and add a supplemental beam so the elevated floor rides solid again, usually in a day.
The hardware under my elevated home looks rusted through, can you replace that?
Yes, rusted connectors and posts are common in these damp pier homes, and we replace the failing supports with steel jacks set on poured footings. We'll add a beam under the span too if it needs the extra carry.
One of the posts under my pier home looks rotted at the bottom, what now?
A rotted post can't hold the floor, so it starts to give above it. We set a new steel jack on a concrete footing right there and tie in a supplemental beam if the span calls for it, and you'll feel the floor firm up the same day.
Why does my floor feel spongy in the room over the crawlspace?
Spongy floors over a damp Jekyll crawlspace usually mean a post rotted or the span lost its support. We work from underneath, setting steel jacks on footings and a beam, and it stops giving underfoot fast.
Can you get under an elevated island home to do this kind of repair?
Definitely, the elevated design actually makes it easier for our crew to get under and set steel jacks on concrete footings and a supplemental beam. Most Jekyll jobs are done from below in a single day.
“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.”
