Pressure Washing FAQs, answered by experts

One of the most important factors to consider when buying a pressure washer is not just psi but also the machine’s overall cleaning power. This is based on both the psi and the GPM. Look for a cleaning rating, or effective cleaning unit (ECU), of up to 8,000 for most residential cleaning projects that require a pressure washer.

If the exterior walls are not thoroughly cleaned before a paint job, the paint could stick to the grime, creating obvious imperfections along the way. Beyond that, painting over a freshly-cleaned wall just about doubles the lifespan of the paint, from three or four years to seven to ten years. 

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

  • Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.

  • Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.

  • Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.

  • Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.

  • Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.

While DIY power washing is possible, professional services ensure thorough cleaning, proper pressure levels, and avoidance of surface damage.

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.
