The Best Time to Pressure Wash

Posted on by Urban Eden Landscaping

It can be difficult to decide when to pressure wash here in Camas, Washougal, and Vancouver Washington. Whether it’s your driveway or parking lot, your patio, deck or your fence, there are several key things to consider before pressure washing your home or business. Here we will discuss some factors to consider when deciding on the best time to pressure wash.


Choosing the right time to pressure wash your property is crucial for achieving the best results and avoiding any potential issues. The ideal time for pressure washing is typically during the spring or fall seasons, as long as rain is limited. These seasons offer the most favorable conditions for the task, ensuring that water can evaporate properly and that the surfaces can dry thoroughly.


One key reason to avoid pressure washing during rainy weather is that rain can complicate the job and even cause damage to your property. Pressure washing in the rain makes the process less effective, as the water from the pressure washer may mix with rainwater, diluting the cleaning solution and making it less potent. Additionally, wet surfaces can be more challenging to clean, and there is a risk of slipping, which poses safety concerns.

Algae and Mildew

Spring and fall are also considered prime seasons for pressure washing because they go hand in hand with the growing seasons of algae and mildew. By addressing these issues early in the season, you not only eliminate existing growth but also prevent future infestations from taking hold. In regions like the Pacific Northwest, where damp conditions can contribute to the buildup of residues, it’s recommended to pressure wash at least once a year to maintain the cleanliness and longevity of your property.  

For areas with high levels of dust, dirt, and mildew due to proximity to main roads or freeways, more frequent pressure washing may be necessary. The constant stirring of dust and launching of dirt in such environments can lead to faster accumulation on surfaces. Similarly, spaces with high moisture and limited sunlight are prone to increase mildew growth, making it essential to clean these surfaces more regularly.


Temperature also plays a crucial role in the effectiveness of pressure washing. Ideally, temperatures between 50-80 degrees Fahrenheit are recommended for the best results. Extreme temperatures, either too hot or too cold, can impact the performance of cleaning solutions and the overall effectiveness of the pressure washing process. 


It’s important to note that pressure washing at night is highly discouraged due to safety concerns for both individuals and the property. Limited visibility at night increases the risk of accidents, and proper lighting may not be available to assess the cleanliness of surfaces accurately. 

By choosing the right time to pressure wash, considering seasonal factors, and following safety guidelines, you can ensure a successful and efficient cleaning process for your property. Urban Eden Landscaping would love to help with any of your pressure washing needs.
