Nine foundation services for Hattiesburg, priced: piering $4,000–$15,000, slab work $3,500–$12,000, drainage $1,500–$6,000, cracks $400–$1,500, concrete leveling $500–$2,500. The elevation survey is free.
Work on the perimeter
Where the foundation meets the ground. Piering transfers load onto steel beneath the sections the contour shows moving, and slab repair handles a slab that is dropping in part rather than whole. Both are priced by how much of the perimeter is involved, which is why the survey precedes the number. Because the formation is interbedded, settlement repair covers why the contour matters more than the crack. On interbedded ground a driven pier can refuse on a sand lens — helical piers report what they are actually in.
Work inside the house
What you actually live with. Sloping and uneven floors are the symptom most people notice first, and crack repair is the last step rather than the first — worth doing only once the readings say movement has finished.
Work outside the house
The cheapest category and the most commonly skipped. Drainage correction changes how much water reaches material that responds to it, and concrete leveling deals with flatwork that has dropped over the same buried transitions without touching the structure.
Foundation Piering & Underpinning
Steel where the contour says, and nowhere it does not. Extent is the price, not depth.
Slab Foundation Repair
A slab spanning two different grounds is being asked to bridge a boundary it cannot see.
Foundation Crack Repair
Where the crack sits on the footprint matters more than how wide it has become.
Drainage Correction
59.17 inches a year, and expansive layers only care about the water that reaches them.
Concrete Leveling
Flatwork crosses the same buried boundaries the house does, with none of the weight.
Sloping & Uneven Floor Repair
A floor that falls one way tells you where. A floor that dips in the middle tells you something else.
Do I Need a Structural Engineer?
Usually not — but on ground that varies within a lot, there are three cases where it pays for itself.
Mississippi Licence Rules
Improvements over $10,000 need a Remodeler licence. Most foundation jobs clear that line.

Which service fixes which problem
| What the house is doing | What the contour usually shows | The work | Typical range |
|---|---|---|---|
| One end or one wall dropping | A low stretch, rest flat | Piering that stretch | $4,000–$15,000 |
| A dip through the middle of the house | Both ends higher than the centre | Support either side of the line | $4,000–$15,000 |
| A crack tracking straight across a slab | A buried boundary beneath it | Slab repair | $3,500–$12,000 |
| Damage that reverses between seasons | Readings still near flat | Water management first | $1,500–$6,000 |
| Cracks that never change | Flat, stable | Fill them | $400–$1,500 |
| Driveway dropped, house reads level | Flatwork only | Leveling | $500–$2,500 |
The order that costs least
Survey, water, structure, cosmetics. The survey is free and settles everything after it. Drainage is the cheapest physical work and on this ground can be the entire answer where the readings are still near flat. Support goes only where the contour calls for it. Cracks get filled last, because filling first throws away the measurement history and gets redone anyway. Full pricing on the cost guide. Whether a policy responds depends on the cause, and on this formation the evidence is unusually easy to get wrong.
Not sure which one you need?
Most people arrive here having noticed one specific thing rather than knowing a service name: a door that stopped latching this season, a crack that keeps reappearing after it is filled, a floor that feels out of level near one wall, brick opening in a stair-step above a window, or a gap under a skirting board that was not there last year. Any of those is a reason to have someone look, and none of them is a diagnosis on its own. What causes them differs, which is why the visit comes before the quote.
Service questions
Which of these will I actually need?
The contour decides and it costs nothing to get. Sections reading low over a stretch point at support. Damage that reverses between seasons points outside, at water. Readings that come back flat with unchanged cracks point at cosmetic work, or at nothing yet.
Can one company do the water and the structure?
It is why we price both in one document. Setting steel under a wall while runoff still concentrates against it stabilises that stretch and leaves the supply feeding whatever comes next. Seeing both halves priced lets you stage it deliberately rather than discover the second half later.
Do you ever recommend nothing?
Frequently, and the free survey is what makes that possible to say. A contour that comes back flat with crack widths unchanged across a full wet and dry season means keep measuring. Nobody has paid for that finding, which is rather the point.
Which of these do I actually need?
Start from what you have noticed. Sticking doors and sloping floors point at movement and a measured evaluation; a crack you can see daylight through points at repair; water standing against the house after rain points at drainage. The elevation survey settles it, and it is free.
