In general, mild weather is the best time to get ideal pressure washing results. It is important that the temperature is neither too high nor too cold. Obviously, freezing temperatures in winter or scorching heat in midsummer would not be suitable for pressure washing. You can pressure wash your house in spring or fall.
The best season is spring or summer because of the mild climate and longer sunny days. The ideal is to pressure wash the house between March and November. But, if you have to do it during the winter, be sure to avoid temperatures below 40 degrees. If the temperature is too low, it could damage your pressure washer, put it at risk and freeze the surfaces you wash.
Therefore, during the colder months, it is best to wait until the afternoon to wash the house under pressure. So you don't want to work when it's too cold or too hot. What temperatures are considered “right” for exterior painting and pressure washing? Painting professionals recommend choosing days with temperatures between 50 and 90 degrees Fahrenheit (around 70 degrees is perfect). However, just as important as the temperature itself is the consistency of that temperature.
Certain regions during certain seasons experience significant temperature fluctuations as day turns to night and vice versa. Normal drops and rises aren't a problem, but if temperatures drop below 32 degrees Fahrenheit at night, the paint may not cure properly. Ideally, the temperature should be moderate, around 60 to 70 degrees Fahrenheit. This will give you enough time to work without worrying about the water freezing or evaporating, adding complications unnecessary.
A good rule of thumb is to pressure wash your house between the months of March and November. This is the ideal time period to ensure that your home is clean and protected before the inclement winter and freezing temperatures arrive. While temperature, climate and weather conditions play an important role in determining the best time to pressure wash the house, the decisive factor is the condition of the house. While pressure washing can normally be done at all temperatures, cold weather can make the process difficult. It is recommended to avoid pressure washing in extreme weather conditions, such as tropical storms, thunder and lightning, and in any type of weather that may pose a danger to your health and safety.
The answer is simple: homeowners should do a good pressure wash at least once a year or twice a year for the best results.
