Power washing is a great way to clean siding, decks, patios, and driveways. It can dramatically improve your home’s appearance — but using the wrong technique or pressure can cause damage.
Here are some key tips to get the best results safely.
1. Use the Right Pressure Setting
Different surfaces require different pressure levels.
- Low pressure: siding, painted surfaces
- Medium pressure: decks, fences
- High pressure: concrete and driveways
Too much pressure can damage wood, strip paint, or force water behind siding.
2. Keep a Safe Distance
Holding the nozzle too close can leave marks or damage surfaces, especially on softer surfaces like wood.
Start farther away and move closer gradually until you find the right balance between cleaning power and safety.
3. Use the Correct Spray Tip
Pressure washers come with different nozzle tips:
- Wide spray (40°) for general cleaning
- Narrow spray (15°–25°) for tougher areas
Choosing the right tip helps prevent streaking and damage.
4. Watch for Water Intrusion
Avoid spraying directly into:
- Vents
- Electrical outlets
- Window seals
- Door frames
Water intrusion can lead to interior damage or mold.
5. Work in Sections
Clean in small sections from top to bottom to avoid streaking and ensure even results.
