The Top 3 Pressure Washing Mistakes Homeowners Make (And How to Avoid Them) 

Spring cleaning is right around the corner, and for many homeowners, that includes pressure washing their exterior surfaces. Whether it’s blasting stubborn grime off a patio, refreshing the siding, or giving your deck a new lease on life, pressure washing is one of the most effective ways to make your property sparkle.  

But here’s the catch—not knowing what you’re doing can lead to costly mistakes that outweigh any benefits. The wrong settings, poor technique, or even improper preparation can cause damage to your home or landscaping. Fortunately, by following a few simple tips (or better yet, calling professionals), you can avoid these pitfalls entirely. 

Here are the top three pressure washing mistakes homeowners make and how to avoid them. 

1. Using the Wrong Pressure Settings for Different Surfaces

Why It’s a Problem 

A pressure washer’s power is both its greatest strength and its riskiest feature. Apply too much pressure, and you could easily strip paint, splinter wood, or crack delicate surfaces like vinyl. On the other hand, using too little pressure often leaves grime and stains behind, making all your effort wasteful. 

How to Avoid It 

• Test Different Settings: Different surfaces require different pressure levels. For example, wood decks and siding need low-pressure settings to avoid damage, while concrete or stone pathways can handle higher pressures.  

• Choose the Right Nozzle: Your pressure washer likely came with several nozzle options. A fan-shaped nozzle often works best for most surfaces, as it provides even coverage without concentrating too much force in one area.  

• Start Low and Work Up: Begin with the lowest pressure setting and gradually increase it until you find what works best for the surface you’re cleaning. 

The Professional Solution 

Pressure washing professionals are trained to adjust pressure settings for various materials. They know how to safely clean everything from delicate siding to tough concrete without causing damage, ensuring a thorough but protective clean every time. 

2. Failing to Test an Area First

Why It’s a Problem 

Have you ever seen unsightly streaks, discoloration, or a damaged patch after cleaning? That’s what happens when homeowners skip an important step in the pressure washing process—testing a small, inconspicuous area first. Some surfaces are more fragile than they look, and once you’ve caused damage or discoloration, there’s no going back. 

How to Avoid It 

• Always Test a Small Patch First: Choose a hidden or less noticeable spot on the surface you plan to wash. Test the pressure settings and your technique there to ensure no damage occurs before moving on to larger areas. 

• Pay Attention to Older or Painted Surfaces: These are especially prone to damage. For example, an old deck might have softened wood that splits under high pressure, while painted surfaces can easily flake or strip. 

The Professional Solution 

Professionals are skilled at assessing materials and surfaces before starting work. They conduct tests to find the optimal pressure and technique for your specific surfaces, avoiding unnecessary damage or mess. 

3. Damaging Landscaping Around the House

Why It’s a Problem 

Pressure washers don’t discriminate. Plants, flowers, mulch, and other landscaping features are often collateral damage when homeowners don’t consider the power of the water stream. Direct spray or runoff water can uproot plants, wash away soil, or even harm shrubs and flowers with the force alone. 

How to Avoid It 

• Protect Landscaping: Cover plants, flowers, and delicate landscaping features with tarps or plastic sheets to shield them from direct spray or harsh runoff. 

• Work Strategically: Adjust your angle so that the pressurized water stream is directed away from landscaping. Also, be cautious with cleaning chemicals, as many can harm plants or seep into the soil. 

The Professional Solution 

Professionals know how to safely handle pressure washers around landscaping. They use proper techniques, disposal methods for runoff, and protective coverings to ensure the beauty of your home extends to your yard as well. 

Why Hiring a Professional Is the Smarter Choice 

Pressure washing may seem simple, but as you can see, the smallest misstep can result in costly repairs or replaceable damage. This is why hiring a professional is often the smartest choice for homeowners. Here’s why: 

Avoid Costly Mistakes

Incorrect techniques or oversight can lead to splintered decks, cracked siding, and damaged landscaping. Professionals avoid these errors entirely, ensuring your home looks better—not worse.
