Driveway Cleaning Cost in Garner, NC | Concrete & Asphalt 2026
Garner Pressure Washing • August 29, 2026 • 7 min read
Your driveway has gone dark. Black algae is creeping up from the edges. You got a quote for $200 and another for $400, and you are not sure why the same-size concrete costs $200 more.
This guide breaks down what driveway cleaning costs in Garner, why prices vary for concrete versus asphalt, and what happens if you pressure wash the sealer off yourself.
Driveway Cleaning Cost in Garner: By Material
Professional driveway cleaning in Garner runs $130 to $250 for a typical two-car drive, which works out to roughly $0.15 to $0.45 per square foot. That is the same range published in our Garner pressure washing cost guide. Square footage, algae severity, and red clay or oil staining decide where inside the range a specific driveway lands, and oversized or heavily stained drives can price above it.
Typical Garner driveway cleaning prices (at $0.15-$0.45 per sq ft):
| Driveway Size | Light Algae | Heavy Algae or Staining |
|---|---|---|
| 400-500 sq ft | $130-$160 | $160-$225 |
| 500-700 sq ft | $140-$190 | $190-$250 |
| 700-1,000 sq ft | $160-$230 | $230-$320 |
| 1,000+ sq ft | Quoted after walk-through | Quoted after walk-through |
Most Garner homeowners have driveways in the 500-800 sq ft range, which is why the $130-$250 two-car band covers the majority of jobs. Asphalt drives usually land at or slightly below a same-size concrete drive because the gentler low-pressure process is faster.
Concrete vs Asphalt: Method Matters
Concrete Driveway Cleaning
Concrete is dense and durable. It can handle higher pressure (2,000-3,000 PSI) without damage. However, most concrete in Garner has a sealer applied (factory or homeowner-installed) to protect against staining and water intrusion.
Safe concrete cleaning process:
- Low to moderate pressure (1,500-2,500 PSI, not full pressure)
- Biodegradable, algae-killing detergent applied and allowed to dwell
- Pressure is used to remove loosened algae, not to strip the surface
- No sealer damage if done correctly
Cost: $130-$250 for most two-car drives, depending on size and algae severity
Why it can cost more than asphalt: Concrete is slower to clean (denser surface, algae bonds stronger), and care is required to preserve any existing sealer. Our driveway and concrete cleaning service uses a surface cleaner so the finish comes out even instead of striped.
Asphalt Driveway Cleaning
Asphalt is porous and softer than concrete. High pressure can damage the surface, roughing it up and accelerating deterioration. Asphalt also breaks down from UV exposure and heat, so aggressive cleaning can speed that damage.
Safe asphalt cleaning process:
- Low pressure (800-1,500 PSI, similar to soft wash for houses)
- Algae-killing detergent applied
- Gentle rinse to avoid scuffing the surface
- No high-pressure blasting
Cost: at or slightly below a same-size concrete drive
Why it costs less: Lower pressure and less aggressive process means faster work. The tradeoff: asphalt requires gentler handling because it is naturally fragile.
What Affects Driveway Cleaning Cost
Algae and Staining Severity
A driveway with light green film (early algae): Easier, lower cost.
A driveway that has turned dark (years of algae): Harder, takes more chemical and time, higher cost.
Impact on price: Up to $150 difference between light and heavy buildup on the same driveway.
Driveway Age and Sealer Condition
A new driveway with intact sealer: Moderate pressure is safe.
An old driveway with worn sealer: Lower pressure required to avoid further damage.
Impact on price: Older driveways might cost $50-100 more because extra care is required.
Oil Stains and Tire Marks
Asphalt driveways often have oil stains from vehicles. Concrete may have tire marks (rubber from tires).
Oil stain removal: +$25-$75 depending on stain age and coverage. Fresh oil is easier to remove; old oil is set and requires stronger chemistry and longer dwell.
Tire marks: Usually removed in standard cleaning; separate treatment rarely needed.
Multiple Surfaces (Driveway + Patio)
If your cleaning includes driveway + patio + sidewalk, pricing typically bundles or discounts per-surface pricing.
Driveway + patio combo: Often $50-75 cheaper than booking separately because equipment and setup stay on-site.
Why DIY Pressure Washing Fails (And Damages Concrete)
Many homeowners rent a pressure washer (3,000-4,000 PSI) and damage their own driveway.
What Goes Wrong
High-pressure rental machines strip the sealer off concrete. Once the sealer is gone:
- Water penetrates and freezes in winter (concrete cracks)
- Oil stains absorb into the surface and cannot be removed
- The concrete looks dull and gray instead of bright
Asphalt is even worse: high pressure roughens the surface and accelerates tar breakdown.
Cost of Repair
Resealing concrete after DIY pressure washing: $200-$400 (roughly the cost of professional cleaning in the first place).
Asphalt patching after damage: $300-$800+ depending on depth.
The Math
Driveway cleaning professionally: $130-$250 for a typical two-car drive (includes sealer preservation)
DIY rental: $75 rental + $50 chemicals + risk of $200-800 repair = real risk of higher total cost
Professional is the smart move for concrete and asphalt both.
How Often Should Driveways Be Cleaned?
Once per year is the standard for the Triangle. Humidity and oak tree shade create ideal algae conditions. Most driveways get noticeable algae within 12 months.
Timeline after cleaning:
- Months 0-4: Driveway stays clean
- Months 4-8: Light green film starts returning (barely visible)
- Months 8-12: Algae becomes obvious; driveway looks “due”
- Month 12+: Heavy algae; driveway looks dirty and weathered
Annual cleaning keeps your driveway ahead of the curve. Waiting until heavy buildup means longer work and higher cost.
Can You Reseal After Cleaning?
Yes. Professional driveway cleaning removes dirt and algae but does not reapply sealer. After cleaning is the perfect time to reseal, because sealer bonds best to a clean, dry surface. Sealing is a separate trade we do not offer; a concrete or paving contractor can quote it, and scheduling them within a week or two of the cleaning gives the best result.
Frequently Asked Questions
Q: Can I pressure wash my concrete driveway myself?
A: You can try, but rental machines (3,000-4,000 PSI) often strip the sealer and damage concrete without removing algae effectively. You end up with lower cost ($75 rental) but higher risk ($200-800 repair). Professional cleaning ($130-$250 for most two-car drives) preserves your driveway.
Q: Why does my driveway get so dark (algae) in the shade?
A: Shade + humidity is perfect for algae growth. North-facing driveways under oak trees get darker faster. Sunny driveways take 12-18 months; shaded driveways may see heavy algae in 8-12 months.
Q: Does algae on my driveway hurt the concrete?
A: Algae itself does not damage concrete, but the moisture it creates does. Algae holds water on the surface, which penetrates the concrete, and during winter freeze-thaw cycles, that water expands and cracks concrete. Cleaning prevents moisture retention and extends driveway life by years.
Q: What if I have an old asphalt driveway that is cracking?
A: Professional soft wash can still clean it, but very high pressure will accelerate damage. We use low pressure and assess the condition first. Cracks should be sealed (cheap fix, $50-100) before cleaning to prevent water intrusion.
Q: Will sealer protect my concrete from algae?
A: Sealer protects from water penetration and staining but does not prevent algae growth. Algae still grows on sealed concrete, but it does not absorb into the surface. When you clean sealed concrete, it stays bright longer because the dye is on the surface, not absorbed.
Q: How long does driveway cleaning take?
A: A typical 600 sq ft driveway takes 1-2 hours depending on algae severity. The time includes detergent dwell (we let chemistry work while equipment is rinsed and prepped).
