Why Brunswick homes need this, and how we do it
Brunswick has some of the oldest housing stock in the county, and it shows under the floor. Interior girders often rest on wood posts set on a single block or straight on the dirt, spanning joists that run longer than the framing really wanted. Add a hundred years of termite pressure and additions built on whatever was handy, and you get bounce in the center of a room and a floor that tilts from the hall down to the kitchen.
We rebuild the support with steel. New adjustable jack posts go in on real concrete footings, and a supplemental steel or engineered beam carries the long spans so the joists stop flexing. Rotted posts and girders come out, and where an addition was set on a makeshift block we give it a proper base. The lift is slow so plaster and trim in the old house survive it.
The result is a floor that sits level, holds still, and quits its squeak. Because the wet crawl spaces here keep feeding rot and pests, we usually talk with you about drying and sealing the space so the new support has a chance to last.
What’s included
The whole load path - not just the soft spot
Every supplemental beams & jacks we do in Brunswick, 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 Brunswick homeowners ask us
My old Brunswick house has girders sitting on posts right in the dirt, is that why the floor slopes?
That's a common setup in older Brunswick homes, and posts sitting on bare dirt sink and rot, which drops the girder and slopes your floor. We replace them with steel jacks on poured concrete footings and add a supplemental beam to hold the line.
The floors in my old house dip and bounce, what would cause both at once?
Usually it's a long span with tired support plus a post or two that settled, so you get sag and bounce together. We set adjustable steel jacks on new footings and a beam beneath the span, working from underneath, and it firms right up.
Can these long spans in these old homes really be fixed from underneath?
Yes, in most Brunswick homes we do the whole job from the crawlspace by adding a supplemental steel beam and jacks on concrete footings mid-span. It carries the long run and takes the bounce out, often in one day.
The girder under my house looks like it's rotted where it meets the post, is that bad?
That spot rots often when posts sit on dirt and stay damp, and it lets the floor drop above it. We cut in steel jacks on footings and a supplemental beam to carry the load, replacing the rotted section so the floor levels back out.
My hallway floor tilts to one side in this old place, why does that happen?
A tilt like that usually means a support post under one side settled into the soft ground. We lift and steady it with adjustable steel jacks on concrete footings and add a beam if the span needs it, all from below in about a day.
“We had stair-step cracks and a door that wouldn't close. They installed push piers and actually lifted the corner back. The cracks closed up and everything works again. They explained every step and the price didn't change.”
