"Jordan did a great job at a rental house we own! He communicated well about when he would go by to bid the job, was timely with the bid, and showed up to work when promised. Would definitely hire him again!"

"Mason is extremely detailed-oriented, and showed a genuine interest in trying to help to improve these old bricks to the best of his ability. He truly went above and beyond today. So just based upon his work today, I would highly recommend him for general brick cleaning."

Pressure Washing questions, answered by experts

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.

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.

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.

Yes, you can pressure wash metal fences. However, as with other fencing materials, it’s important to use the right PSI when pressure washing a steel, aluminum, or other metal fence. If you apply too much pressure, you could strip off the paint, ruin the protective coating, or otherwise damage the fence.

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.
