Can you power wash vinyl siding?

Vinyl siding is common for many homes and helps keep your home safe from the weather. Keeping your siding clean from mold, mildew, and debris helps keep it from deteriorating and gives your home a fresh look. Vinyl siding can be power washed but should be done with care and knowledge of the correct way to prevent damage to your siding.

Check Your Home:

Always check your siding for cracks, chips, or other damage. If any damage is found, repair the area before power washing. If it can't be repaired, avoid power washing these spots to prevent further damage. Be mindful of windows, screens, gutters, and outside lights. Power washers are powerful and may damage other home fixtures. Always be mindful of other people's and pets' proximity because power washers can cause harm at high pressures.


PSI (pounds per square inch) is a measurement for pressure. 1000-1500 PSI with a low-pressure nozzle is recommended for vinyl siding. When power washing your siding, always start with a low PSI and the proper nozzle. Adjust your PSI as needed. High pressures can cause damage to your siding. Always check your power washer's manual on how to adjust your PSI settings.


Always make sure to give yourself proper distance from your home. Start further away and work your way closer to the house. If you notice your siding moving, you are either too close to the home or your pressure is too high.

Homes in drier areas with lots of sunlight may only need to be cleaned every other year. Evaluate your home and environment to judge when and how often you should clean your siding.
