Foundation Repair Cost Factors
When calling for quotes for your home's foundation repairs in Phoenix, expect contractors to break down pricing based on the hours needed for labor, the complexity of the project, and any materials that are needed to complete the project. The average cost per square foot for all types of foundation repairs in Phoenix is $2 to $15. For a foundation that's 1,500 square feet in size, getting the foundation fixed might cost between $3,000 and $22,500.
Foundation Size
Foundation size directly impacts the cost of fixing it. The larger the home, the larger, heavier, and more structurally complex the foundation tends to be. Large foundations also often require more equipment and materials for repairs.
The per-square-foot cost of foundation repairs ranges between $1.50 and $12 per square foot on average. The range accounts for everything from minor sealant upgrades to full epoxy replacement. Prices can go much higher per square foot for certain materials, but assume this range on average when considering the full area of your home's foundation.
| Foundation Size (Sq. Ft.) | Average Cost |
|---|---|
| 500 | $1,000–$7,500 |
| 1,000 | $2,000–$15,000 |

Foundation Type
Your options for foundation repairs will vary based on your home’s foundation type, whether it’s a basement, a concrete slab, cinder blocks, bricks, or a crawl space. Prices for each foundation type also depend on the type and extent of damage since there’s no single solution for all foundation problems.
With most homes in Phoenix having simple slab foundations, costs for repairs are generally lower. However, homeowners may need to pay slightly higher costs for basement foundation repairs in older or historic homes throughout the city.
| Foundation Type | Repair Cost | Difficulty Level |
|---|---|---|
| Concrete slab | $350–$17,000 | Low |
| Cinder block and brick | $2,000–$34,000 | Medium |

Type of Issue
Every foundation problem comes with a unique price tag, particularly when a contractor has to take multiple approaches to fix it. Foundation crack repair costs, for example, depend on whether the problem stems from drainage problems, soil instability, or poor installation.
Leaks may require contractors to add a range of waterproofing methods to your foundation or investigate the source of the water from inside or outside your home. In more extreme cases, a bowing wall or sinking foundation will require major reinforcement or even replacement.
| Type of Issue | Average Cost |

| Cracks | $600–$3,300 |

Does Foundation Repair Affect Home Value?
A home with a crumbling or cracked foundation in Phoenix is at risk of being condemned by the city. Severe structural issues with different parts of a foundation can dramatically decrease a home's value because the home may no longer be insurable or sellable. By calling someone who inspects home foundations at the first warning signs of foundation issues, you may be able to fix the problem before it grows into something that will cost more to fix.
