"Window Wizards did an excellent job. They pressure washed my driveway, walkway, back patio, and also washed and cleaned my patio doors. Window Wizards was very professional and did a thorough job and I would definitely hire them again and refer them to others."

"I was looking to get the oil stains out my driveway. He informed me from the beginning that it wouldn?t come out completely but around 90 percent. He came out two days prior to service to treat the stains. This chemical you leave for 48hrs. He came back on the third day and pressure washed the driveway. I?m happy looks great"

Pressure Washing questions, answered by experts

Your deck may look or feel fuzzy after pressure washing because the high-pressure spray tears some wood fibers as it removes the outer layer of dead and discolored wood. This fuzzy effect is a normal part of the pressure-washing process and will go away on its own in a few weeks. You can opt to spot-sand your deck if you’d like to remove it more quickly.

Whether you need to winterize your pressure washer depends on where you store it. If you can keep it in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, if the machine will be stored in freezing temperatures, any liquid left in the water pump can freeze, expand, and cause severe damage. To prevent this, add antifreeze to keep it in good condition. While some suggest emptying the machine with compressed air, this can be a tedious process that may not fully drain the liquid. Regardless of storage conditions, it is also good practice to empty the gas chamber and refresh the oil before winter storage.

No, pressure washing isn’t recommended for cartridge filters. The high pressure can damage the filter paper, and the gentler pressure from a regular garden hose will work to rinse the cartridge filter. If the cartridge is very dirty or has algae or mineral buildup, you can use a muriatic acid solution to soak the filter and remove the buildup.

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.

Yes, you can use a pressure washer to effectively clean debris, dirt, and grime from your gutters, but it must be done with caution to avoid damage. Always use a low-pressure setting, with a recommended range between 1,200 and 1,800 PSI. Excessive pressure can bend or dent aluminum gutters, damage seams, peel paint, or even knock shingles off your roof, potentially leading to leaks and moisture issues. For a safer alternative, consider soft washing or cleaning them by hand. When using a pressure washer, it is safer to use gutter elbow extensions from the ground rather than climbing a ladder, as the force can cause instability. Due to the risks, you may want to hire a licensed and insured contractor for the job.
