Floor Support Systems in Middle Tennessee
Floor support systems
Stabilize weak, bouncy, and uneven floors.
Why are my floors sagging or uneven? This is often caused by weakened floor joists, rotted support beams, or foundation settlement beneath the home. A floor that moves under your feet is telling you the support below it is no longer carrying the load it was built to carry.
Typical Middle TN cost$4,500–$10,000typical sagging-floor repairPublished market range, not a quote. See the cost guideThree different problems that feel identical underfoot
A soft spot in the kitchen and a sloping hallway can come from completely different failures, and the wrong repair on the wrong cause doesn't hold. That's why the assessment matters more than the product.
In older Middle Tennessee homes we most often find original wood posts sitting directly on dirt, girders that were never sized for today's loads, and joist ends that have been damp for years.
Weakened floor joists
Long spans, undersized lumber, notched or drilled framing, or joists that have simply been carrying too much for too long.
Rotted support beams
Girders and posts that have been in contact with damp soil and lost strength permanently. Rot doesn't reverse — it gets replaced.
Foundation settlement beneath the home
When the footing itself has dropped, the fix is under the foundation, not under the floor. See foundation piers
A topo heat map of your floor, so support goes where it is needed
Your estimate is built on measurements we take inside the crawlspace. When we do the work, a full FoundationScan® report with topo heat map is generated as part of the job — it takes several hours, and it shows exactly where the structure needs support.
For floors, that means we know how far each area has dropped and in which direction before we set a single post — so the supports go where the load actually needs to be carried, and the stabilization can be planned instead of guessed.

Put the load back on solid ground, then keep it there
Can sagging floors be repaired without replacing them? Yes — in most cases we stabilize the existing framing rather than tearing out floors. Supports go on engineered footings, the load is transferred gradually so the finishes upstairs stay intact, and the floor is held at a measured elevation.
Adjustable steel supports
Set on polymer base pads — engineered footings sized for the load — not on dirt, not on stacked block. Adjustable means the floor can be fine-tuned later if it needs it.
Supplemental beams
Where a span is simply too long, a new girder shortens it and spreads the load across more support points.
Joist & beam repair
Rotted or overloaded joists and beams get sistered with new lumber, so the load has sound wood to carry it.
Guaranteed stabilization
Stabilized at the measured elevation and checked against the scan. Stay on the annual service call and we guarantee it holds.
Fixing the wood without fixing the water resets the clock
Rot is a moisture problem that showed up as a structural problem. If we replace framing in a crawlspace that stays damp, the new wood starts down the same road as the old wood. That's why floor support and encapsulation usually appear on the same estimate — the repair holds the house up, the encapsulation keeps it that way.
Then we come back every year
Our service doesn't end with installation and final payment. We're here for the long haul. Our annual service call — $250 a year — covers a service on all equipment we installed, a fresh assessment and a new FoundationScan® report, so changes are caught before more damage can occur. No contract required, though many homeowners lock in three to five years up front and hand that record to the buyer when they sell.
On a floor repair that matters. Stay on the annual service call and we guarantee the stabilization: the yearly scan shows the floor is holding exactly where we left it, and the supports are adjustable if it isn't.

Floor and structure questions
How much does it cost to fix sagging floors in Middle Tennessee?
- National cost guides put structural repairs to a sagging floor at $4,500 to $10,000, depending on how many supports, beams and joists the floor needs. A supplemental beam on new posts typically runs $1,500 to $5,000, and sistering a damaged joist about $200 to $500 per joist. The FoundationScan® elevations decide how much of that your floor actually needs, and your written estimate is the real number.
Will my floor be perfectly level after the repair?
- The goal is a floor that is stabilized and stays put. Supports are set to the elevations the FoundationScan® measures, and framing that has sagged for decades won’t always come back dead flat without cracking the plaster or tile above it. The steel supports are adjustable, so the floor can be fine-tuned later if it needs it.
What’s wrong with the wood posts under my house?
- Many older Middle Tennessee homes still sit on their original wood posts, set straight on the dirt. Damp soil rots the bottom of a post and it slowly sinks, which shows up upstairs as a soft or sloping floor. Adjustable steel supports go on engineered footings sized for the load, so nothing rests on bare soil.
What does it mean to sister a floor joist?
- A new length of lumber is fastened alongside a joist that is cracked, rotted or undersized, so the pair carries the load the old one couldn’t. It saves tearing out the floor above. Rot that runs the full length of a joist means replacing it, and the damp that caused the rot has to be dealt with too.
Why do my doors stick when the floor sags?
- Door frames are square when they’re built. When the floor under one side drops, the frame racks out of square and the door binds at the top corner or swings open on its own. It is one of the signs that points to the support under the floor, and it is worth a measured look before anyone planes the door.
Why are my floors sagging or uneven?
- This is often caused by weakened floor joists, rotted support beams, or foundation settlement beneath the home.
Can sagging floors be repaired without replacing them?
- Yes. In most cases we stabilize the existing framing with adjustable steel supports on engineered footings and new beams rather than tearing out floors.
How do I know if my home has a foundation problem?
- Common signs include cracks in walls or floors, uneven or sloping floors, doors or windows sticking, bowing or leaning basement walls, gaps around trim, doors, or exterior brick, and water seepage in the crawlspace or basement. If you notice any of these, it's best to have a professional assessment.
Are your services guaranteed?
- Yes. All of our work is backed by warranties on both materials and labor for peace of mind.
Can foundation problems affect my home's value?
- Yes. Unrepaired foundation or moisture issues can lower property value and cause problems during a home sale or assessment.
