A 20x20 concrete driveway is one of the most common driveway sizes for Kansas City homes. It’s large enough for two vehicles, easy to maintain, and fits well on many residential lots. Because of that, homeowners often use it as a reference point when comparing concrete prices.
In this guide, we’ll break down how much a 20x20 concrete driveway costs in Kansas City, what’s included in that price, and why estimates can vary even when the square footage looks the same.
Quick Cost Overview for a 20x20 Concrete Driveway
A 20x20 driveway equals 400 square feet of concrete. In the Kansas City area, most professionally installed concrete driveways of this size fall into these ranges:
- Basic replacement (standard finish): $4,800 – $7,000 Upgraded thickness or reinforcement: $6,500 – $9,000 Decorative or stamped finishes: $8,000 – $12,000+
These prices assume installation by a qualified kansas city concrete contractor and include labor, materials, and standard preparation.
Why Driveways Cost More Than Patios
Homeowners are often surprised that driveways cost more per square foot than patios. The reason is load.
Driveways must support:
- Passenger vehicles Delivery trucks Garbage trucks crossing the apron Turning and braking forces
Because of this, driveways typically require thicker concrete, stronger mixes, and more reinforcement than patios or walkways.
Concrete Thickness and Strength for a 20x20 Driveway
Most Kansas City contractors recommend:
- 5 inches minimum for residential driveways 6 inches for heavier vehicles or frequent traffic
In addition, driveway concrete is often poured at 4,000 PSI or higher to handle vehicle loads and freeze-thaw cycles.
How Much Concrete Is Needed for a 20x20 Driveway?
Understanding volume helps explain pricing. A 20x20 driveway at standard thickness uses approximately:
- 5-inch thickness: ~6.2 cubic yards 6-inch thickness: ~7.4 cubic yards
Because this is a relatively small volume, short-load fees can play a role in overall cost.
Base Preparation: The Hidden Cost Factor
In Kansas City, expansive clay soil makes base preparation critical. Many driveway failures are caused not by bad concrete, but by inadequate base support.
Proper driveway prep typically includes:
- Removal of the existing driveway Excavation to correct depth Installation of compacted aggregate base Correction of slope for drainage

Removing an Existing Driveway
Most 20x20 driveway projects in Kansas City are replacements rather than new installs. Removal and disposal add cost due to labor, equipment, and dump fees.
Factors that affect removal pricing include:
- Thickness of the old slab Presence of rebar or wire mesh Access for equipment Distance to disposal sites
Drainage and Slope Requirements
Driveways must slope away from garages and structures. Poor drainage is a leading cause of driveway damage in Kansas City, especially during heavy rain events.
Professional contractors plan slope carefully to:
- Prevent water from pooling Protect foundations Reduce freeze-thaw damage
Joint Placement and Crack Control
Concrete cracks as it cures. Control joints help manage where those cracks occur.
For a 20x20 driveway, contractors typically install:
- Saw-cut control joints Expansion joints at the garage
Proper joint placement improves appearance and longevity.
Decorative Options and Their Cost Impact
While many homeowners choose a broom finish, decorative options are available:
- Stamped concrete Colored concrete Decorative borders
These options increase labor and material cost, but also enhance curb appeal.

Seasonal Pricing Considerations
Spring and fall are peak seasons for driveway replacement in Kansas City. During these periods, scheduling demand can affect pricing. Winter work may be cheaper but often requires special precautions.
Long-Term Maintenance and Lifespan
A properly installed concrete driveway can last 25–40 years. Simple maintenance like sealing, avoiding harsh deicers, and managing drainage can extend its lifespan.
Common Mistakes Homeowners Make
- Choosing the lowest bid without reviewing scope Accepting thin slabs for driveways Ignoring drainage issues Skipping joint planning
Final Advice for Kansas City Homeowners
When budgeting for a 20x20 driveway, focus on durability rather than price alone. A slightly higher upfront investment often saves money long-term.
Repair vs Replacement for Existing Driveways
Some homeowners consider patching or resurfacing instead of full replacement. While repairs can extend lifespan temporarily, underlying base or drainage issues often remain. For older driveways with widespread cracking or settlement, replacement is usually the better long-term choice.
Permits and Code Considerations
Depending on location and scope, driveway replacement may require permits or inspections. A professional contractor will handle these requirements and ensure compliance with local codes.
