When is the Best Time to Pressure Wash Your House?

When considering pressure washing your Austin TX home, the time of year and time of day are both important things to think about before performing this chore. Overall, you should have your house pressure washed at least once a year. While you could rent a machine and do it yourself, the best, longest-lasting results are guaranteed when you hire a professional.

In general, the best time for pressure washing your home’s exterior is spring or summer, starting as early as March and extending as late as October. But timing your pressure washing job goes beyond just the time of year. Time of day, temperature, weather conditions and the state of your siding all come into play.

Time of Day

It’s best to pressure wash your house in direct, bright sunlight. This will give you the highest visibility level possible. Doing this late in the day or when there’s significant cloud cover can cause shadows, which in turn can hide dirty or streaky spots. For the most even clean possible, wait for bright, direct sunlight, which also serves to dry the water faster.

Don’t pressure wash at night for obvious safety and visibility reasons. Likewise, don’t pressure wash during a major storm or a lightning storm. Not only could you get electrocuted, but falling debris could also hit you or the pressure washer. Use some common sense and you will be fine!


An ideal temperature range is between 50 and 80 degrees Fahrenheit. When the weather is too cold, the water will freeze on contact, posing possible damage to your home. On the flip side, when it’s too hot, the heat can cause evaporation of the cleaning solutions too quickly, which renders them less effective.

Type of Siding

Check with the manufacturer of your home’s siding prior to pressure washing. Certain types of siding are more fragile than others and will need a lower pressure setting as well as gentler cleaners. 

Even if you have brick or stone siding on your house, take extra care. Too much pressure can cause pitting or dislodging of materials such as mortar. To avoid this, use a low-pressure nozzle to avoid chipping or cracking your siding. Better yet: let the professionals handle this. They know the perfect amount of pressure to apply so as to prevent damage.

No matter which season you choose to pressure wash your house, wear closed-toe shoes, gloves, and eye protection (goggles) to shield yourself from the chemicals you’re using. Wear a hat, earplugs, and a face mask if pressure washing in inclement weather.
