Foundation Repair Cost Factors 

Foundation repair costs in St. Louis generally vary based on the type of foundation your home was built on. On average, St. Louis homeowners pay between $1.50 and $10 per square foot for repairs. For a St. Louis home with a 1,500-square-foot blueprint, costs to have repairs done professionally by a contractor with labor and materials included can range from $2,250 to $15,000.

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 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.

Most homes in the St. Louis area have basement foundations below the frost line to help mitigate issues stemming from the cold climate. While this typically increases foundation repair costs compared to homes with simpler slab foundations, a generally lower cost of doing business in St. Louis helps to keep costs for repairing all types of foundations below average.

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.
