"Frank the owner of this fine establishment dealt with my husband and me. He was very professional throughout our entire transaction from service pitch, actual pressure washing, and closing of our business together. I appreciated the pride and confidence in his work. My house looks GREAT!!! He was able to remove all the green mold build up! We definitely will be using Complete Power Washing St Louis again...Thank you Frank!!!"

"Great experience from start to finish. Scott did an excellent job power washing our siding and gutters—everything looks noticeably cleaner and refreshed. He was professional, on time, and paid attention to detail. Pricing was fair for the quality of work. Would definitely recommend and use him again."

Pressure Washing FAQs, answered by experts

Before pressure washing, you can spray your deck lightly with a deck cleaning solution made of equal parts oxalic acid and water. Oxalic acid has a brightening effect that will lighten mold stains and return the deck to its original freshly-sawn look. Allow the solution to sit for about 20 minutes before pressure washing so it has time to take effect.

The ideal PSI (pounds per square inch) for a pressure washer depends on the surface you are cleaning. For general home use, a pressure washer with a range of 2,000 to 3,000 PSI is recommended and powerful enough for most residential projects.

The specific PSI you should use varies by task:

  • High-Pressure Tasks (2,500-3,000 PSI): Tough materials like concrete, stone, masonry, and brick can handle higher pressures. This is suitable for removing stubborn stains from driveways or cleaning graffiti.

  • Low-Pressure Tasks (around 600-1,300 PSI): Softer surfaces require a gentler touch to avoid damage. Use a low PSI setting for cleaning wood decks (especially softwoods like pine and cedar), vinyl siding, outdoor furniture, and stucco.

For best results, choose the right nozzle for your surface, such as a 15-degree nozzle for siding or a surface cleaner attachment for driveways. Using an extendable wand can also make the work easier and more ergonomic.

Professional power washing removes built-up dirt, mold, and mildew, which preserves exterior surfaces and improves curb appeal. Hiring a professional ensures the cleaning is done effectively and without damaging surfaces.

Annually, or more if located in humid or heavily polluted areas.

Whether you need to winterize your pressure washer depends on where it will be stored. If it's kept in a location where temperatures could drop to freezing, any liquid left in the water pump can freeze, expand, and cause severe damage to the machine. To prevent this, you can add antifreeze to the pump. While emptying the machine with compressed air is an alternative, it can be a tedious process and may not remove all the liquid. If you can store the pressure washer in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, regardless of storage conditions, it is good practice to empty the gas chamber and refresh the oil before storing it for the winter.
