## 1. Groundworks — best overall for whole-home repair
Groundworks is the largest foundation services company in the U.S., operating well-known regional brands (JES, Mount Valley, Indiana Foundation Service, and others). Because they handle foundation piering, crawl space encapsulation, and basement waterproofing under one roof, they are the strongest pick when your home has more than one problem. Expect engineer-led inspections, in-house manufacturing of piers, and a nationally backed transferable warranty that survives a sale.
## 2. Ram Jack — best for engineered steel piers
Ram Jack designs and manufactures its own driven and helical steel piers and operates through a vetted franchise network. Their engineering-first reputation makes them a favorite for serious settlement where load calculations matter. Repairs typically carry a lifetime, transferable warranty.
## 3. Olshan Foundation Solutions — best for expansive clay soil
Operating across the South since 1933, Olshan specializes in the expansive clay soils common in Texas, Oklahoma, and Louisiana that cause seasonal heave and settlement. Their Cable Lock and bell-bottom pier systems are tuned for these conditions, and their longevity is itself a signal of reliability.
## 4. AB Chance dealer network — best for helical piers
AB Chance (a Hubbell brand) pioneered the helical pier and supplies certified dealers nationwide. You are buying a proven product installed by a trained local contractor, with the manufacturer standing behind the hardware. Ideal for lighter structures and tight-access sites where helicals shine.
## 5. Supportworks dealer network — best for finding a vetted local pro
Supportworks is a network of independently owned contractors who must meet engineering and customer-service standards to carry the brand. If you want a local company but worry about fly-by-night operators, a Supportworks dealer gives you national-grade products and accountability with local service.
## 6. Dalinghaus Construction — best on the West Coast
Dalinghaus serves California, Arizona, and Nevada with push piers, helical piers, and slab repair, and is known for thorough engineer reports and a 25-year transferable warranty. A strong regional choice for homeowners in seismic and slab-on-grade markets.
## 7. Acculevel — best for Midwest crawl spaces
Acculevel focuses on the Midwest, pairing foundation piering with crawl space and water management — the exact combination many Indiana, Ohio, and Kentucky homes need. Free inspections and a lifetime transferable warranty round out the offer.
## What foundation repair costs in 2026
Costs vary widely by method and severity. As general planning ranges:
- Minor crack sealing or epoxy injection: $500–$1,500
- Helical or push piers: $1,300–$3,000 per pier (most jobs use several)
- Full perimeter pier stabilization: $10,000–$30,000+
- Crawl space encapsulation: $5,000–$15,000
Most homeowners spend between $5,000 and $20,000 for meaningful structural repair. Always get a written scope, the number of piers, and the engineering basis in the bid.
## How to choose the right foundation repair company
1. **Demand an engineer's report.** A licensed structural engineer's assessment — ideally independent of the contractor — protects you from over- or under-scoping.
2. **Get three written bids.** Compare method, pier count, and total load, not just price.
3. **Read the warranty closely.** Favor lifetime and transferable warranties, and confirm what voids them.
4. **Verify licensing, insurance, and reviews.** Check state licensing and look for a long, consistent track record.
5. **Beware pressure tactics.** Legitimate firms give you time and documentation; "sign today" discounts are a red flag.
## Frequently asked questions
**How do I know if my foundation needs repair?** Watch for stair-step cracks in brick, doors and windows that stick, sloping or bouncy floors, and gaps where walls meet ceilings. Any sudden or widening crack warrants an inspection.
**Is foundation repair covered by insurance?** Usually not, unless caused by a covered peril (like a burst pipe). Settlement from normal soil movement is typically excluded.
**Does foundation repair hurt resale value?** A documented, warrantied repair generally reassures buyers far more than visible, unaddressed damage.
