Top Ten Most Common Mistakes Made When Pressure Washing

Pressure washing is a fantastic way to revitalize the exterior of your home in the Tri-Cities area of Tennessee. With its ability to remove dirt, grime, mold, and other unsightly stains, pressure washing can make your property look brand new again. 

However, as with any DIY project, there are pitfalls that homeowners often stumble upon. In this post, we will explore the most frequent mistakes people make when pressure washing their homes and provide invaluable tips from the experts at Cates Pressure Washing to ensure your cleaning endeavor is a successful one.

The Most Common Mistakes in Pressure Washing Your Tri-Cities Home

1) Choosing the Wrong Pressure Washer:

One of the primary mistakes homeowners make is selecting the wrong pressure washer for the job. Different surfaces require varying levels of pressure to avoid damage. 

Using a high-pressure washer on delicate materials like wood or vinyl siding can lead to irreparable harm, such as cracks and splintering. Conversely, using a low-pressure washer on tough stains may result in ineffective cleaning and wasted time.

To avoid this mistake, consult a professional at Cates Pressure Washing to help determine the right pressure washer for your specific needs. They can guide you on selecting the appropriate PSI (pounds per square inch) and GPM (gallons per minute) for your home's materials.

2) Neglecting a Test Patch

Before you begin pressure washing the entire surface, it is crucial to conduct a test patch on a small, inconspicuous area. This allows you to gauge the effectiveness of the pressure washer and the impact on the material. Many homeowners skip this step and proceed to clean the entire area, only to discover later that the pressure was too high, causing damage or leaving uneven streaks.

Take your time with a test patch and adjust the pressure settings accordingly. This simple step can save you from costly repairs and headaches down the road.

3) Failing To Use Proper Cleaning Solutions

Water alone might not be sufficient to remove stubborn stains and contaminants. Many homeowners make the mistake of solely relying on water, which can lead to a less satisfactory outcome. Using appropriate cleaning solutions specifically designed for pressure washing can significantly improve the results and help prevent future growth of mold and mildew.

4) Overlooking Safety Precautions

Pressure washing can be deceptively powerful, and failing to observe safety precautions can lead to injuries. Common mistakes include not wearing protective eyewear, using the pressure washer on a ladder, or not securing the electrical connections correctly.


Always wear protective gear, including goggles and gloves, to shield yourself from debris and chemicals. Place the pressure washer on stable ground and avoid using it from an elevated position. If unsure about the safety measures, consult Cates Pressure Washing or hire their professional services.

5) Washing Windows Incorrectly

When pressure washing, it's easy to overlook the fragility of windows. Using a high-pressure stream directly on windows can cause cracks, shattered glass, or compromised seals. Unfortunately, this mistake can be costly and time-consuming to rectify.

Be cautious around windows and avoid pressure washing them directly. Instead, consider hand washing or using a lower pressure setting while keeping a safe distance from the glass.

6) Not Cleaning Gutters Before Pressure Washing

Pressure washing is an excellent method for removing grime from gutters, but it is essential to clean them out beforehand. Neglecting this step can result in clogged downspouts and potential water damage during pressure washing. Remove leaves, debris, and other blockages from the gutters to ensure a smooth and effective cleaning process.

7) Pressure Washing Electrical Fixtures

Another common mistake is pressure washing electrical fixtures, such as outdoor outlets, light fixtures, and electrical panels. Water and electricity are a dangerous combination that can lead to electrocution or electrical malfunctions.

Before pressure washing, cover or seal off any electrical fixtures and connections with waterproof materials to prevent water from reaching them. If you're unsure about how to do this safely, consult an electrician before starting the cleaning process.

8) Ignoring Landscaping and Plants

Pressure washing can be harmful to delicate plants and landscaping around your home. The high-pressure water can strip away leaves, damage flowers, and even uproot young plants. Additionally, some cleaning solutions may contain chemicals that could be harmful to vegetation.

To protect your plants, water them thoroughly before pressure washing to ensure they're saturated, which minimizes their ability to absorb chemicals. Use plastic sheeting or tarps to cover plants and delicate landscaping during the cleaning process. Alternatively, if possible, consider trimming back plants before pressure washing to reduce potential damage.

9) Using the Wrong Nozzle or Spray Pattern

Pressure washers come with various nozzles or adjustable spray patterns, each serving a different purpose. Using the wrong nozzle or spray pattern can lead to inefficient cleaning or, worse, cause damage to surfaces.

For example, a narrow, high-pressure nozzle may be suitable for tough stains on concrete but could be too aggressive for delicate siding materials. Be sure to read the pressure washer's manual to understand the different nozzles and spray patterns and use the appropriate one for each cleaning task.

10) Neglecting Regular Maintenance:

Like any equipment, pressure washers require regular maintenance to function optimally. Neglecting maintenance tasks, such as cleaning filters, checking hoses for leaks, and inspecting the nozzle for wear, can lead to decreased performance and potential breakdowns.

Before each use, inspect your pressure washer for any signs of wear or damage. Clean and replace filters as needed, and store the machine properly when not in use to prolong its lifespan and ensure reliable operation.
