Foundation Repair Cost Calculator

Foundation repair costs range from $250 for hairline crack sealing to $15,000+ for structural piering. The type of problem, severity, and foundation type determine where your project falls in that range.

Cost by Problem Type

• Hairline cracks (non-structural): $250–$800. Epoxy injection seals the crack and prevents water infiltration. Cosmetic and preventive, not structural.
• Stair-step or horizontal cracks: $1,000–$5,000. These indicate structural movement and may require carbon fiber strips ($500–$1,500 per strip) or wall anchors ($800–$1,500 each).
• Bowing basement walls: $3,000–$12,000. Wall anchors or carbon fiber reinforcement prevent further movement. Severely bowed walls may require excavation and rebuild.
• Settling or sinking: $5,000–$15,000+. Steel push piers ($1,000–$2,000 per pier) or helical piers ($1,500–$3,000 per pier) lift and stabilize the foundation. Most homes need 6–12 piers.
• Water/drainage issues: $2,000–$10,000. Interior drain tile, sump pump installation, or exterior waterproofing. Often needed alongside structural repairs.

Foundation Type Affects Repair Method

• Poured concrete: Most straightforward to repair. Crack injection is effective for most issues.
• Concrete block: More prone to bowing and step cracking. Block walls lose strength faster than poured concrete.
• Pier and beam: Shimming and jacking are less expensive ($1,000–$5,000) but may need repeated attention.
• Slab-on-grade: Settling requires piers driven through the slab. Access is more difficult, increasing costs.

Why Acting Early Saves Money

Foundation problems always get worse — and more expensive — over time. A $500 crack repair today can become a $10,000 piering job in 3–5 years if ignored. Most reputable companies offer free inspections and 25-year or lifetime transferable warranties on structural repairs.
