"I highly recommend Los Angeles Pressure Washing, Inc., the services are prompt and professional. I recently made a major mistake of filling in the crevices of my brick-paved pavement. I used a very fine cement and it did the job of filling the crevices, however, it left an unsightly white-wash residue on my brick-paved pavement. I thought that it would be impossible to remove the unsightly cement film. However, L.A. Pressure Washing, Inc. did a beautiful job of restoring and removing all the cement residue from my bricks with minimal mess. The price was very reasonable too and I don't have to redo my brick-paved pavement with costly expenses. Thank you L.A. Pressure Washing team."

"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."

Pressure Washing FAQs, answered by experts

Yes, you can pressure wash with just water. The force of the water alone is often enough to remove dirt, grime, and debris from many surfaces. However, for tougher stains like grease, mildew, or algae, adding a detergent or cleaning solution can enhance the cleaning power. Be sure to use the appropriate nozzle and pressure settings for the surface to achieve the best results without causing damage.

The life expectancy of a pressure washer depends on the model, its overall quality, and how well it is maintained. Most pressure washers have a life expectancy rating, typically measured in hours of use. Many models are rated for up to 500 hours, which can translate to a lifespan of around 10 years for a homeowner who uses the machine for about 50 hours per year. If you plan on using your pressure washer regularly, you may want to look for a higher-quality model rated for 2,000 hours or more.

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.

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.

Experts typically recommend pressure washing your driveway at least once per year to keep it looking great while preventing stains, cracks, and unwanted vegetation. However, if your driveway gets a lot of use, you might want to pressure wash it more often to keep it looking like new.
