The Do’s and Don’ts of Residential Pressure Washing
Residential pressure washing is one of the best ways to maintain your home’s curb appeal, structural integrity, and cleanliness. However, using the wrong techniques or pressure settings can cause costly damage. Knowing what to do—and what to avoid—can make all the difference in keeping your home’s exterior looking its best.
✅ The Do’s of Residential Pressure Washing
If done correctly, pressure washing can extend the lifespan of your home’s exterior and prevent buildup of harmful substances like mold, mildew, and dirt. Here’s what you should do:
🔹 1. Do Use the Right Pressure Setting
Not all surfaces can handle the same level of pressure. Using too much force on delicate materials can cause irreversible damage. Here’s a general guideline:
- Low pressure (1,300–1,800 PSI) – Best for siding, wood, vinyl, and painted surfaces.
- Medium pressure (1,800–2,800 PSI) – Suitable for brick, composite decking, and asphalt driveways.
- High pressure (2,800–3,500+ PSI) – Used for concrete, stone, and industrial cleaning.
🔹 2. Do Pre-Treat Stains and Mildew
Before pressure washing, apply a pre-treatment to break down tough stains, mold, and mildew. Using biodegradable cleaning solutions helps lift dirt without harming the environment.
🔹 3. Do Maintain a Safe Distance
Holding the pressure washer too close to surfaces can strip paint, etch wood, and cause irreversible damage. A minimum distance of 12 inches is recommended.
🔹 4. Do Start from the Top Down
Always begin washing at the top of your home and work downward. This prevents streaking and dirty water running onto cleaned areas.
🔹 5. Do Use the Correct Nozzle
Pressure washers come with different nozzles that affect water flow and intensity. Selecting the right one ensures safe and effective cleaning:
- 0-degree (red): Extreme pressure, not recommended for home exteriors.
- 15-degree (yellow): Heavy-duty cleaning for stains on concrete or metal.
- 25-degree (green): General-purpose nozzle for siding, patios, and driveways.
- 40-degree (white): Best for windows, cars, and delicate surfaces.
🔹 6. Do Protect Nearby Plants and Windows
Cover plants, flowers, and outdoor furniture to prevent damage from water pressure or chemicals. Use lower pressure on windows to prevent cracks.
❌ The Don’ts of Residential Pressure Washing
🚫 1. Don’t Use High Pressure on Siding or Windows
Excessive force can crack windows and force water under siding, leading to mold growth and insulation damage.
🚫 2. Don’t Pressure Wash Peeling or Chipped Paint
If your home’s exterior paint is peeling, pressure washing will strip it further. Instead, schedule a repainting job after cleaning.
🚫 3. Don’t Forget Safety Gear
Pressure washers operate at high velocity and can cause injury if used improperly. Always wear:
- Goggles – To protect your eyes from debris.
- Gloves – Prevents hand injuries from high-pressure water.
- Non-slip boots – Ensures stability when working on wet surfaces.
🚫 4. Don’t Wash in Windy Conditions
Wind can blow back water, detergent, and debris, making cleaning less effective. Always check the weather forecast before starting.
🚫 5. Don’t Use Harsh Chemicals
Avoid using bleach or toxic cleaners, as they can damage your home’s exterior and harm surrounding plants.
🏠 What Areas of Your Home Should Be Pressure Washed?
Pressure washing isn’t just for siding! It works wonders on:
- Driveways & Walkways – Removes oil stains, dirt, and discoloration.
- Patios & Decks – Clears algae buildup and prevents slippery surfaces.
- Fences & Gates – Restores wood, vinyl, and metal fencing.
- Roofs & Gutters – Prevents moss buildup that can lead to leaks.
