Keeping your driveway clean improves curb appeal and helps prevent built-up dirt, algae, and stains from damaging the surface. For safe and effective driveway pressure cleaning, always match the pressure setting to the driveway type.
The ideal pressure, measured in PSI (pounds per square inch), depends on the material, since too much pressure can cause unnecessary wear.
Recommended Pressure by Driveway Surface
Here is a quick guide to what pressure setting to choose for each type of driveway surface:
Concrete Driveways
Concrete is durable and able to withstand higher pressure. We recommend 2,500 to 3,500 PSI to remove oil stains, dirt, and mildew.
Paver Driveways
Pavers are made from interlocking paving stones made of concrete, stone or bricks. They are durable, but intense pressure may disturb the joint slabs. Recommended range for pressure cleaning service: 1,500 to 2,500 PSI.
Exposed Aggregate Driveways
The decorative aggregate on these driveways may loosen with too much pressure. Use moderate pressure, 2,000 to 3,000 PSI.
Asphalt Driveways
Softer than concrete and easily damaged by excessive pressure. Use a gentle spray pattern and keep the nozzle moving. Recommended: 500 to 1,500 PSI.
Brick Driveways
Avoid high pressure that can erode mortar joints. Lower settings often provide the best results. Recommended pressure: 1,000 to 2,000 PSI.
When to Hire a Professional
Choosing the correct PSI is only part of the process. Surface condition, stains, and cleaning techniques also affect results. If you’re unsure, a professional driveway pressure cleaning can assess your driveway and use the safest pressure level to deliver a thorough clean without causing damage.
