"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."

"I had my red tile roof over the garage pressure washed this morning by Carlos Almendaro. He was punctual and did a great job which included thoroughly cleaning the site. His cost was reasonable. I appreciated his professional demeanor. A job invoice would greatly add to the service. Thank you Carlos. Gil Payne Laguna Niguel"

"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

Whether or not you can use a pressure washer to clean your gutter guards depends on the type of gutter guard you have and the strength of the pressure washer. Most gutter guards can handle a low-pressure setting but check first. If you’re unsure if your gutter guard is designed for pressure washing, check your manufacturer’s instructions, ask a pro, or use a garden hose to clean the gutter guard instead. As gutter guards age, they become less resistant to the strong forces of a power washer, so treat older gutter guards with more care.

You can certainly utilize a pressure washer to effectively clean your garage floor. If you're dealing with oily residue, consider adding a degreaser to the pressure washer solution. Prior to using the pressure washer, make sure to thoroughly sweep the garage floor to eliminate any loose dirt or debris.

Begin the pressure washing process from the back of your garage, which is closest to your home, and work your way towards the front. This ensures that the water and dirt are directed outside. In case you've applied a cleanser or degreaser, it's a good idea to give the floor another pass with clean water using the pressure washer to ensure a thorough rinse.

Professionals use high-pressure steam cleaners, brushes, and specialized cleaning solutions for effective results.

Costs depend on fabric type, drape size, cleaning method, and whether additional services like pressing or deodorizing are included.

Yes, it is highly recommended to wash a house's exterior before painting to ensure the best results. Cleaning the surface removes dirt, dust, grime, mold, mildew, and old paint, which allows the new paint to adhere properly and results in a smoother, long-lasting finish. Failing to clean can lead to poor adhesion, peeling, and an uneven appearance. Pressure washing is an efficient method for this, but be cautious not to use excessive pressure that could damage siding or wood. For materials like vinyl or stucco, soft washing might be a better option. After washing, allow sufficient drying time, such as three to four days, before painting to prevent trapping moisture, which can cause blistering or peeling.
