Concrete Contractor in St. Louis, MO

Ask how long the slab will need to cure before foot traffic, vehicles, or sealing. Rushed cure times shorten the life of the work. Also ask for a written scope, pricing breakdown, and the credentials or insurance documentation that apply to this trade before work starts.

In St. Louis, quotes usually move with square footage, demolition, base prep, reinforcement, finish type, and curing schedule.

Ask whether the price includes demo, base preparation, reinforcement, control joints, and final cleanup - not just the pour itself.

A standard concrete driveway costs $6-$12 per square foot installed, or $3,000-$7,000 for a typical 2-car driveway (400-600 sq ft). Stamped or decorative concrete costs $12-$20+ per square foot. Factors include thickness (4-6 inches standard), reinforcement, grading, old driveway removal, and decorative finishes.

Concrete reaches initial set in 24-48 hours and can handle foot traffic. It reaches about 70% of its full strength in 7 days, which is when you can drive on it. Full curing takes 28 days. Avoid heavy loads, chemicals, and deicing salts for at least 30 days. Curing time varies with temperature and humidity.

Repair is suitable for minor cracks (less than 1/4 inch), small spalling, or surface discoloration. Replace when you see large cracks, significant settling, heaving, widespread deterioration, or when repair costs exceed 50% of replacement. If your concrete is over 25-30 years old with multiple issues, full replacement is usually more cost-effective.
