Helical & Push Pier Cost in Marietta, GA: What You'll Pay Per Pier
How much do helical piers cost per pier in Marietta and Cobb County?
Helical and push piers in the Marietta area typically cost $1,400 to $3,500 per pier installed. That range reflects depth to stable soil, pier diameter, and equipment access on your property. The vetted local partner prices each pier individually because every foot of penetration through Cecil red clay adds labor and material cost.
Pier projects are priced per pier, not by the linear foot or the square foot of the house, because each pier is driven to refusal — meaning the contractor we connect you with keeps advancing it until it locks into competent, non-expansive soil below the active zone of the Piedmont clay. On a typical Marietta slab, that can mean 15 to 30 feet of penetration depending on your soil profile.
The licensed local contractor references IRC Section R401 soil-bearing requirements and maps floor elevations before quoting. That engineering step is what makes the final per-pier number meaningful rather than a rough guess. See how helical piers work for a full method walkthrough.
How many piers does a typical settling home in Cobb County need?
Most settling homes in Marietta, East Cobb, Smyrna, Kennesaw, Acworth, and Powder Springs need 3 to 12 piers. A corner that has dropped an inch or two may need only 3 to 4 piers. A full perimeter job on a long ranch-style slab can reach 10 to 12 piers. Pier count is the biggest driver of total cost.
The vetted local partner determines pier count by walking the perimeter, reading crack patterns — especially stair-step cracks in the brick mortar joints common in post-WWII brick ranches throughout ZIP codes 30060, 30062, and 30064 — and measuring floor elevations with a manometer. Sticking doors and windows often cluster near the lowest point and help identify where piers are needed.
Because piers are priced individually, the total scales with pier count: a small corner stabilization using only a few piers sits near the low end of the overall $3,500 to $25,000 foundation repair range, while a large multi-side or whole-perimeter job approaches the top of it. Most Cobb County homes land somewhere in the middle. Use the foundation cost estimator to get a rough range before your free inspection.
- Corner or isolated settlement: 3–5 piers
- One full wall or side of the house: 5–8 piers
- Two sides or wrap-around settlement: 8–12 piers
- Pier count is confirmed on-site, not over the phone
What factors make helical pier costs higher or lower in my area?
Depth to stable soil is the top variable. Marietta and West Cobb sit on deep Piedmont Cecil clay that can stay active 20 to 30 feet down; reaching the stable saprolite layer below it means more pier sections and higher cost. Tight equipment access, steep grades, and interior piers under load-bearing walls also raise the price.
In West Cobb — neighborhoods around Sandy Plains Rd and Powder Springs — the soil transitions from Cecil clay into weathered granite called saprolite. Saprolite is granular and relatively stable, but it can occur at inconsistent depths, which means the contractor may need to drive piers deeper in one corner than another on the same house.
Conversely, homes on higher ground near Kennesaw Mountain or along Johnson Ferry Rd in East Cobb sometimes encounter competent rock shallower, which can reduce overall pier depth and cost. The only way to know is a site-specific inspection. Narrow side yards, decks, and HVAC equipment near the foundation can add access surcharges. Review all the cost variables on the foundation cost estimator page.
- Depth to stable soil (biggest driver): 15–35 ft typical in Cobb County
- Pier diameter: standard vs. heavy-duty load-rated shaft
- Equipment access: open yard vs. tight side passages or interior work
- Soil type: Cecil clay vs. saprolite transitions in West Cobb
- Number of corners or load points that need support
What is the difference between helical pier cost and push pier cost?
Helical piers use a screw-like helix plate and are rotated into the soil; push piers are driven hydraulically using the weight of the house. Both land in the $1,400 to $3,500 per pier installed range in Marietta, so neither is reliably cheaper. The right choice depends on soil conditions and load, not on cost alone.
Helical piers are preferred when the contractor we connect you with needs to work in limited headroom — crawl spaces and tight areas near the Chattahoochee River corridor — or where soil conditions make hydraulic driving unreliable. Push piers tend to work better where the existing footing is solid enough to brace against during driving. Because both fall in the same price band, the method decision is driven by engineering, not budget.
The helical piers vs. push piers comparison page covers the technical trade-offs in detail. For cost purposes, assume the same per-pier range applies to both methods and focus your budget planning on pier count and depth rather than method selection.
Are piers worth the cost compared to cheaper foundation fixes in Marietta?
Piers are the right answer when the foundation is still moving due to soil settlement. Cheaper fixes like crack injection ($300–$3,000) or slab leveling ($600–$2,500) address symptoms — they do not stop the movement. If your Cobb County soil is still shrinking or settling, injecting a crack without stabilizing the foundation is money spent twice.
The smectite minerals in Cecil red clay cause the soil to shrink 6 to 8% seasonally — up to 10 to 15% in a hard drought. When the clay dries and pulls away from footings, the house settles. Crack injection with epoxy or polyurethane closes the gap in the concrete, but it does nothing to stop the footing from moving further next August when Cobb County's typical dry fall sets in again.
If a licensed structural engineer (or the vetted local partner during the free inspection) confirms the movement has stabilized — common in older homes that have already settled to a new resting point — then crack injection or slab repair alone may be appropriate. If the house is still actively moving, piers are the durable solution. The cost estimator and free inspection together help you decide which category your home falls into.
What does the free inspection include and how does it produce a firm pier quote?
The free inspection is a full structural walkthrough by the licensed local contractor — no pressure, no obligation. They measure floor elevations across the slab, map crack locations, probe the soil near the footing, and calculate the pier count and depth needed to stop the movement. You receive a written, per-pier quote before any work starts.
We are not a contractor and we do not perform the work. We connect Marietta-area homeowners in ZIP codes 30060, 30062, 30064, 30066, 30067, and 30068 — and throughout Smyrna (30080/30082), Kennesaw (30144/30152), Acworth (30101), and Powder Springs (30127) — with one vetted, licensed, and insured local foundation repair partner. That partner pays the referral fee; you pay nothing for the connection or the inspection.
The written quote will specify pier type (helical or push), shaft diameter, estimated depth, pier count, and total installed price. That document is what you compare against any other quotes you gather. Schedule through the free foundation inspection page or call (678) 329-9460.
Why does foundation repair in Cobb County cost so much overall?
Cobb County's Piedmont geology — deep, expansive Cecil red clay that swells in the wet spring (March through May) and shrinks in the dry fall (August through October) — means foundations work harder here than in most U.S. markets. That constant movement cycle demands deeper piers, more robust repair methods, and more careful engineering than shallow soils require.
Metro Atlanta receives 50+ inches of rain per year, and that moisture feeds the swell-shrink cycle of the smectite-bearing Piedmont clay. Each seasonal cycle can shift footings by fractions of an inch; over 20 to 30 years those fractions add up to visible settlement, sticking doors, and diagonal drywall cracks at window corners. Homes built in the 1980s and 1990s — especially crawlspace and basement subdivisions in East Cobb and Kennesaw — often show their first serious symptoms at the 25- to 35-year mark.
The good news is that pier-based repairs, done correctly, are long-lasting. The vetted local partner backs their pier work with a warranty.

Frequently asked questions
Can I get a per-pier price over the phone without an inspection?
The vetted local partner can quote the per-pier range — $1,400 to $3,500 in the Marietta area — but cannot give you a firm total without measuring floor elevations and confirming pier count on-site. Pier count varies too much by soil depth and settlement pattern to estimate accurately without a walkthrough. The free inspection produces the binding number.
Does homeowners insurance cover helical or push pier installation in Georgia?
Standard Georgia homeowners policies almost never cover pier installation because settlement from expansive Cecil clay is classified as a gradual earth-movement exclusion, not sudden damage. A few policies cover sudden events like a broken water main undermining the footing. The free inspection can help document your situation if you plan to file a claim, but coverage is the exception rather than the rule.
How long does a helical or push pier installation take on a typical Marietta home?
The contractor we connect you with typically installs 4 to 8 piers in a single day on an accessible Cobb County slab. Larger jobs — 10 to 12 piers, or homes with limited equipment access — may run two days. The house remains livable throughout; piers are installed from the exterior in most cases and from inside crawl spaces when needed.
What is the disclosed-referral model and does it cost me anything?
We are not a contractor. We are Stratum Relay LLC, a lead-referral and marketing service that connects Cobb County homeowners with one vetted, licensed, and insured local foundation repair partner. The partner pays the referral fee — you pay nothing for the connection. The free inspection is genuinely free, with no obligation to proceed.
Do helical piers raise a settled foundation back to level?
Partial lifting is often possible. The contractor we connect you with applies hydraulic pressure during installation and can recover some lost elevation in many cases — typically a portion of the total settlement, not always 100%. The inspection and written quote will specify whether lifting is the goal or whether the aim is to halt further movement and stabilize at current grade.
What are the warning signs that my Cobb County home needs piers rather than a simpler fix?
Piers are likely the right answer when you see ongoing, progressive settlement: doors that stick worse each year, new diagonal drywall cracks appearing at window and door corners, stair-step cracks widening in brick mortar joints, or noticeable floor slope. A one-time crack that has been stable for years may qualify for crack injection alone. The free inspection draws that line.
