The cost to seal a driveway in St. Louis ranges from $190 to $950, with most homeowners paying around $470. Your actual cost depends on several factors specific to your home and the St. Louis market.
Sealing is priced per square foot — a standard two-car driveway (400–600 sq ft) is the primary cost factor.
Cracks, potholes, and oil stains must be repaired before sealing. Significant crack filling or patching can add $200–$500 to the job.
Coal tar sealant is cheapest but faces environmental restrictions. Asphalt emulsion is most common. Acrylic sealants cost more but last longer and are eco-friendlier.
Two coats of sealant provide the best protection and longevity, typically adding 30–50% to the material cost versus a single coat.
Individual cracks should be filled with hot rubber crack filler ($1–$3 per linear foot) before sealing for the best results and longest seal life.
The Midwest has a strong pool of skilled tradespeople, and labor rates tend to be moderate compared to coastal cities. Union and non-union shops both compete, giving homeowners options on pricing.
Driveway sealing in St. Louis generally does not require a permit for standard installations. Check with your local building department if your project involves panel work or structural changes.

Yes — driveway sealing is a feasible DIY project. A 5-gallon bucket of sealant ($20–$40) covers about 400 sq ft. Clean the driveway thoroughly, fill any cracks, apply sealant with a squeegee applicator, and allow 24–48 hours to cure. Two thin coats are better than one thick coat.
