Home › Helical Piers
Helical piers are screw-in steel shafts that transfer a settling Huntsville house down to soil that can actually hold it — past the swell-shrink red clay and, when needed, past the fill or limestone soft spots that let a corner drop. Typical installed cost is $1,000–$3,000 per pier. A vetted local pro inspects for free, tells you whether helicals, push piers, or slab leveling is the honest fix, and puts the price in writing with no obligation.
Helical piers Huntsville are a settlement repair, not a crack-seal — the pattern that usually leads here is a corner that's dropped.
Helical piers are a settlement repair, not a crack-seal. The pattern that usually leads here:
If the concrete itself has sunk but the ground has finished moving, mudjacking or foam lifting is usually cheaper and enough. If you mainly see hairline cracks with no slope, start at foundation crack repair. Helical piers are the tool when the ground is still the problem. The broader slab repair guide covers both paths on one page.
Three local conditions show up on almost every settlement call. Valley-floor lots sit on expansive red clay that swells through North Alabama's wet winters (Huntsville averages more than 50 inches of rain a year) and shrinks hard in August droughts, ratcheting footings a little each cycle. Newer subdivisions from Madison through Meridianville, Harvest, and east Athens often sit on builder-placed fill that keeps compacting for five to ten years after closing. And under much of Madison and Limestone counties the bedrock is limestone karst — rock groundwater slowly dissolves — so soil can migrate into soft spots and a slab that looked fine last spring drops a corner this fall.
A helical pier is a steel shaft with one or more helix plates. Crews rotate it into the ground like a giant screw and watch the torque. When torque says the plates have bitten competent material, they stop, bracket the footing, and lift. That torque number is the whole point on a karst or fill lot: you are not hoping the next layer is better; you have a reading.
Push piers still belong on heavier brick homes over deep, uniform clay — they use the house as the reaction weight. Helicals win when the structure is light, the access is tight, or you need to load the pier the same day. The inspector should be able to explain which case you are in in plain English.
The side-by-side of how each system develops capacity on North Alabama clay and limestone is on the helical piers vs push piers page.
| Repair | Typical range | Best for |
|---|---|---|
| Helical pier (installed) | $1,000 – $3,000 per pier | Settling corners, additions, porches, lighter homes |
| Steel push pier | $1,000 – $3,000 per pier | Heavier brick homes over deep clay |
| Multi-pier stabilization with lift | $5,000 – $15,000+ | Whole-wall or whole-corner settlement |
| Slab leveling (foam or mudjacking) | $600 – $2,500 | Sunken interior slabs when the ground has stopped moving |
Typical ranges from national cost guides, reviewed August 2026. Pier depth, pier count, and access change every job. Your quote from a free on-site inspection may differ. Inspections are free.
A corner drop is often two to four piers. A long wall over soft clay can be eight or more — which is why two houses with the same crack get very different bids. The Huntsville foundation repair cost guide puts pier work next to cracks, crawl spaces, and waterproofing on one page.
Most residential jobs in the metro finish in one to three days. Ask each bidder what their transferable workmanship warranty covers and for how long — it is one of the fastest honest comparisons you can make. We are a free referral service, not the installer; the independent contractor who does the work carries their own licensing and insurance.

Request My Free InspectionTypically $1,000–$3,000 per pier installed. A dropping corner may need two to four; a long wall can need more. These are typical ranges, and the free inspection sets your exact price.
Helicals screw to a measured torque and do not need the house's weight, so they fit additions, porches, chimneys, and lighter frame homes. Push piers still suit heavier brick houses over deep clay. Your inspector should pick based on the structure and the soil — not a catalog preference.
Often yes, because crews keep going until torque proves bearing. Karst soft spots are exactly why a measured install beats a shallow pin. Drainage still matters; piers do not replace gutters and grading.
No. Mudjacking and foam lift a sunken slab from below. Helical piers support the structure on deeper material. If a lifted slab would just sink again, piers are the durable answer. See mudjacking for the leveling side.
