The Austin Homeowner's Guide to DIY Pressure Washing: Dos and Don'ts

Maintaining the exterior of your home in Austin, TX, can be a challenging task, especially considering the city's diverse weather conditions and the accumulation of dust, dirt, and mildew. One effective way to keep your property looking its best is through pressure washing. While hiring professionals like Flyside Service can ensure a thorough and efficient cleaning, many homeowners are eager to take matters into their own hands with a DIY approach. In this comprehensive guide, we'll delve into the dos and don'ts of DIY pressure washing, providing valuable insights, essential tips, safety measures, and common pitfalls to avoid.


  1. Understand Your Equipment:

  • Before embarking on any DIY pressure washing project, familiarize yourself with the equipment. Know the components of the pressure washer, including the nozzle tips, hoses, and trigger gun. Read the user manual thoroughly to understand its specifications and capabilities.

  1. Choose the Right Pressure Washer:

  • Austin homes vary in materials, from brick and siding to concrete and wood. Different surfaces require different pressure levels. Select a pressure washer with the appropriate PSI (pounds per square inch) and GPM (gallons per minute) for the job. Low-pressure models (around 1300-1800 PSI) are suitable for delicate surfaces, while higher pressure (2000-3000 PSI) may be needed for tougher stains on concrete.

  1. Safety First:

  • Prioritize safety by wearing appropriate protective gear, including safety glasses, gloves, and sturdy footwear. Ear protection is also recommended, especially with high-pressure washers that can be loud. Be cautious of electrical outlets and connections to prevent accidents.

  1. Prepare the Area:

  • Clear the area of any obstacles or items that could be damaged by the high-pressure water. Cover delicate plants, electrical outlets, and any outdoor furniture to protect them from water damage.

  1. Use the Right Detergent:

  • Invest in a quality detergent specifically designed for pressure washers. Different surfaces require different cleaning agents, so choose one that suits your needs. Follow the manufacturer's recommendations for dilution ratios and application methods.

  1. Test on a Small Area:

  • Before tackling the entire project, test the pressure washer on a small, inconspicuous area to ensure that it won't cause damage. This allows you to assess the effectiveness of the equipment and adjust settings accordingly.

  1. Maintain a Consistent Distance:

  • Keep a consistent distance between the pressure washer nozzle and the surface being cleaned. Varying the distance can result in uneven cleaning or, in extreme cases, damage to the surface. Typically, a distance of 6 to 12 inches is recommended.

  1. Work from Top to Bottom:

  • Start cleaning from the top of the surface and work your way down. This prevents dirt and debris from running down onto areas you've already cleaned. It's particularly important for vertical surfaces like walls and fences.

  1. Rinse Thoroughly:

  • After applying detergent, rinse the surface thoroughly to remove any residue. Leaving detergent on surfaces can lead to streaking or damage. Use a low-pressure nozzle for the rinse phase.

  1. Regular Maintenance:

  • Clean and maintain your pressure washer regularly. Follow the manufacturer's guidelines for storage and maintenance to ensure longevity and optimal performance.


  1. Using Too Much Pressure:

  • One of the most common mistakes is using excessive pressure. While it might seem like more pressure will yield better results, it can cause irreversible damage to certain surfaces, such as wood and soft siding. Always start with the lowest pressure setting and increase cautiously as needed.

  1. Neglecting Safety Gear:

  • Do not underestimate the power of a pressure washer. Neglecting safety gear can lead to serious injuries. Always wear the recommended protective equipment, including eye protection, gloves, and sturdy footwear.

  1. Ignoring User Manual:

  • Every pressure washer model is different, and it's crucial to understand the specific guidelines outlined in the user manual. Ignoring these instructions may result in equipment malfunction or damage to the surfaces being cleaned.

  1. Using the Wrong Nozzle:

  • Different nozzles serve different purposes. Using the wrong nozzle can lead to uneven cleaning or damage. Start with a wide-angle nozzle for large areas and switch to a narrower nozzle for stubborn stains, adjusting the pressure accordingly.

  1. Skipping the Test Phase:

  • Avoid skipping the test phase on a small, inconspicuous area. Testing allows you to gauge the effectiveness of the pressure washer and ensure that it won't cause damage to the entire surface.

  1. Overlooking Surface Sensitivity:

  • Not all surfaces can withstand the same amount of pressure. Delicate surfaces like wood and vinyl siding require lower pressure, while concrete and brick can handle higher levels. Understand the sensitivity of the surface you're cleaning to avoid unintended damage.

  1. Allowing Detergent to Dry:

  • Leaving detergent on surfaces for an extended period can lead to streaking and damage. Always rinse thoroughly after applying detergent, and avoid allowing it to dry on the surface.

  1. Neglecting Electrical Safety:

  • Pressure washers are powered by electricity or gas. If using an electric pressure washer, be cautious of the power cord and electrical outlets. Keep them dry and use a ground fault circuit interrupter (GFCI) to prevent electric shocks.

  1. Ignoring Environmental Impact:

  • Be mindful of the environmental impact of pressure washing. Avoid washing chemicals into storm drains, as they can harm aquatic life. Choose environmentally friendly detergents when possible.

  1. Working Without a Plan:

  • Pressure washing without a plan can lead to inefficiency and oversights. Develop a systematic approach, starting from the top and working down, to ensure thorough and uniform cleaning.
