Can I pressure wash my driveway?
Know Your Driveway Material
Concrete driveways are the most forgiving and can typically handle 2,500–3,000 PSI. Asphalt is softer and should be cleaned at 1,500–2,000 PSI with a wide fan tip; too much pressure etches the surface. Pavers and brick require even less, around 1,200–1,500 PSI, and you should use a surface cleaner attachment to avoid streaks and sand removal.
If your driveway is sealed, pressure washing can strip the sealer. Check with a small test spot in an inconspicuous area first. For older, cracked, or crumbling surfaces, use the lowest effective pressure or hire a professional.
Technique and Safety
Always use a surface cleaner attachment for flatwork; it cleans evenly and prevents zebra striping. Keep the nozzle moving and hold it at a consistent distance. Work in small sections and overlap passes. Pre-treat oil stains with a degreaser, and use a mild detergent for general grime.
Wear safety glasses, closed-toe shoes, and hearing protection. Never point the wand at people, pets, or electrical outlets. Be careful around garage doors and siding; high pressure can force water behind them, causing rot or mold.
- Test a small area first.
- Use a surface cleaner for even results.
- Pre-treat stains with degreaser.
- Keep pressure low for asphalt and pavers.
- Avoid spraying near electrical outlets and doors.
When to Hire a Pro
If you don't own a pressure washer, renting one costs about $40–$100 per day. Professional driveway cleaning typically runs $0.10–$0.25 per square foot, so a 500-square-foot driveway might cost $50–$125. Hiring a pro is wise for delicate surfaces, large areas, or if you're unsure about the right pressure.
Common mistakes
- Using too much pressure on asphalt or pavers, which can cause permanent damage.
- Skipping the test spot; some surfaces react badly to pressure washing.
- Not pre-treating oil stains; pressure alone often just spreads them.
