Why Allenhurst homes need this, and how we do it
Allenhurst is tract housing built on sandy soil over clay, and that layered ground behaves in two ways at once. The sand near the surface drains and shifts, and the clay below swells and shrinks with moisture. Under a crawl-space home that mix moves the supports around, and over long joist spans the floor above starts to feel soft and springy where a post has dropped or rotted.
We firm it up with new steel. Adjustable jack posts go in on proper concrete footings that reach through the loose sand to firmer ground, and a supplemental steel or engineered beam picks up the spans where the framing has begun to sag. Any post or girder that has softened is replaced. The lift is slow so the finishes above stay intact.
Once the steel is in the soft spots firm up and the floor holds steady. Because the sandy layer holds moisture against the clay, we often recommend drying the crawl space so the new supports stay sound and the floor does not start giving again.
What’s included
The whole load path - not just the soft spot
Every supplemental beams & jacks we do in Allenhurst, 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 Allenhurst homeowners ask us
My Allenhurst tract home has soft floors, and I heard it's sandy over clay here, does that matter?
It does, sandy soil over clay shifts and lets the supports settle, and that's what softens your floor. We add steel jacks on poured concrete footings and a beam under the weak span, working from underneath.
The floor in my tract home feels soft in the middle, what's causing it?
The middle usually sits on the longest span, so when a support settles into that sandy-over-clay soil it softens there. We set steel jacks on footings and a supplemental beam to firm it back up, often in a day.
Why would the ground under my house shift enough to affect the floor?
Sand over clay moves as moisture changes, and that movement lets the supports settle under the floor. We fix it by resetting the load on steel jacks on concrete footings and a beam.
Can you firm up a soft floor in a tract home without a big project?
Absolutely, it's a crawlspace job with steel jacks on footings and a supplemental beam under the soft area. No big project, and most Allenhurst repairs finish the same day.
Is a soft floor in these tract homes something you see a lot around here?
We do, the sandy-over-clay soil under Allenhurst homes tends to settle and soften floors. We'll do a free written inspection and, if needed, set steel jacks on footings and a beam to steady it.
“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.”
