"DD Surface Cleaning was very professional and thorough. Our decks were power washed and sealed perfectly and in a timely manner. We are in the process of making another appointment to have our house power washed! I would definitely recommend him for any project, we would not think of hiring anyone else for our projects!"

"Greenwood power washed and applied stain to the exterior of our house, which had not been touched since 1983! They also repaired woodpecker damage and hand painted the trim. The house looks new! I was amazed at the change in appearance and they were able to match the previous stain perfectly. Scott, Randy and crew were courteous and respectful and extremely professional. I look forward to our next project with them! Highly recommend."

Pressure Washing FAQs, answered by experts

For pressure washing a driveway, a PSI (pounds per square inch) between 2,000 and 3,000 is recommended for both concrete and asphalt surfaces. A pressure of 3,000 PSI is ideal for deep cleaning without causing damage, effectively removing debris, dirt stains, and even oil spills. If your pressure washer has a lower PSI rating, you can still use it, but the cleaning process will take longer. For a more efficient and even clean, consider using a surface cleaner attachment.

Yes, it is safe to use a pressure washer on your house, but the water pressure is very powerful. If you’re not careful, it can put a hole in your wall or cause injuries to yourself or others. But there are several pressure washing tips you can follow to pressure wash safely, including wearing safety gear at all times.

The recommended PSI (pounds per square inch) for cleaning vinyl siding can vary, so it's best to consult the manufacturer's guidelines. Generally, vinyl siding can handle high pressure, from 2,500 to 3,500 PSI. For comparison, more delicate materials like wood and aluminum siding should not face more than 1,500 PSI. To safely disperse the pressure on vinyl, use a tip with a wider spray span, such as a green (25-degree) or yellow (15-degree) nozzle. For routine cleaning of light dirt, a garden hose with a spray nozzle may be sufficient. Always exercise caution to avoid using excessive pressure that could damage the siding.

This answer is a bit tricky because experts say both. You should apply your cleaning solution from bottom to top, but rinse from top to bottom to avoid streaking. When it comes to multi-story houses, you’ll want to start at the top floor and work your way down, but follow the above instructions for each level as if it were an independent structure, rather than washing the whole house as one unit.

Professionals use pH-balanced solutions, fabric protectors, and safe steam cleaning technology for specific fabrics. These products are designed to break down dirt effectively without leaving residues.
