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.

The time it takes to pressure wash your driveway is mainly based on size (but your driveway’s material and condition also play a role). Small driveways can be pressure washed within an hour, medium within two hours, and large within four hours. However, this does not consider any prep time or time that sealing your driveway would take.

Pressure washing is a great way to take care of built-up messes much more easily and quickly than manual scrubbing. Pressure washing can save you energy, time, and even money by getting rid of contaminants that can lead to damage to your home. It can also increase curb appeal if you’re getting ready to make a home sale.

Upkeep for stamped concrete driveways only includes regular rinsing, sweeping, and an annual power wash. During the winter, stamped concrete is very durable in snow and ice, but it's best to avoid the overuse of rock salt for its long-term stability. Additionally, address cracks and potholes as soon as they appear to keep them from growing.
