Get matched with top concrete driveway pros in Whitefish, MT

You can use a pressure washer to clean a whole host of surfaces. The exterior siding of your house is one of the most popular spots, as well as your driveway, garage floor, patio or deck, and even your outdoor furniture. Just be mindful about the amount of pressure you apply to different materials—concrete can handle a lot more than wood, for example.

When comparing installation costs, asphalt is often less expensive upfront than concrete. Asphalt prices typically range from $7 to $15 per square foot, while concrete can range from $3 to $18 per square foot. However, long-term costs should also be considered. Concrete driveways generally last longer (up to twice as long) and require less maintenance, which can make them more affordable over their lifespan. While asphalt has a lower installation cost and is easier to repair, it requires more frequent maintenance, such as sealing, which can add up over time. Therefore, while concrete is more expensive initially, its durability may offset the cost in the long run.

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 ideal frequency for pressure washing depends on the surface being cleaned and your local environmental conditions. For a home's exterior with siding that is safe to wash (such as vinyl, cement, or aluminum), a full wash once or twice a year is a good guideline to remove accumulated dirt, grime, mold, and mildew. You may need to wash more frequently if you live in an area with heavy rain or snow, near a dirt road, or if you notice excessive buildup. Other surfaces have different schedules; for example, a frequently used driveway may need cleaning more often, while outdoor patio furniture might only need to be washed every few years. Use your discretion based on how dirty the area gets.
