The ideal frequency for pressure washing depends on the surface being cleaned and your local environmental conditions. For a home's exterior with siding that is safe to wash (such as vinyl, cement, or aluminum), a full wash once or twice a year is a good guideline to remove accumulated dirt, grime, mold, and mildew. You may need to wash more frequently if you live in an area with heavy rain or snow, near a dirt road, or if you notice excessive buildup. Other surfaces have different schedules; for example, a frequently used driveway may need cleaning more often, while outdoor patio furniture might only need to be washed every few years. Use your discretion based on how dirty the area gets.

If you’re using water pressure above 2,000 PSI, you should wear a full face shield—at 4,000 PSI, a water jet can easily slice through skin. Always wear heavy-duty, waterproof gloves and rubber boots with metatarsal guards. If you’re working with hot water, make sure your gloves are insulated.

When comparing installation costs, asphalt is often less expensive upfront than concrete. Asphalt prices typically range from $7 to $15 per square foot, while concrete can range from $3 to $18 per square foot. However, long-term costs should also be considered. Concrete driveways generally last longer (up to twice as long) and require less maintenance, which can make them more affordable over their lifespan. While asphalt has a lower installation cost and is easier to repair, it requires more frequent maintenance, such as sealing, which can add up over time. Therefore, while concrete is more expensive initially, its durability may offset the cost in the long run.

Professional power washing removes built-up dirt, mold, and mildew, which preserves exterior surfaces and improves curb appeal. Hiring a professional ensures the cleaning is done effectively and without damaging surfaces.
