Concrete Cost in St. Louis
Square-foot pricing is a useful starting point, but it is not the whole bid. Mobilization, demolition, base correction, thickness, access, finish, pumping, drainage, and restoration can dominate the total.
What the estimator includes
Our homepage calculator starts with approximate square footage and a project-type planning rate, then adjusts for finish, existing concrete removal, and access. It applies a small-project minimum because mobilization and setup do not disappear on a small slab.
Costs that may sit outside a basic range
- Steps, retaining walls, footings, thickened edges, or structural design.
- Concrete pumping, traffic control, long buggy routes, or difficult demolition.
- Utility relocation, drainage systems, permits, testing, and surveys.
- Premium colors, complex patterns, multiple borders, or specialized sealers.
- Extensive landscaping, irrigation, fence, or asphalt restoration.
Compare scope before price
A bid that includes deeper excavation, more base, a defined reinforcement plan, pump access, and restoration cannot be compared fairly with a one-line price. Request itemized allowances or clear inclusions, and ask how unknown subgrade conditions will be priced.
Use the range as a screening tool
The calculator helps determine whether a project is roughly within budget and which questions to ask. Only an on-site proposal can account for the property, current material and labor pricing, schedule, and contractor-specific methods.

Should I choose the lowest bid?
Not without comparing the written scope, qualifications, insurance, schedule, payment terms, warranty, and exclusions.
