"I had an outdoor playground set. Adrian was professional and hard-working. Great communication and he brought all the required tools and equipment. He showed up first thing in the morning on a short notice and it was all done before the end of the day. The assembly looks great and I know the kids will love it!"

"Power washed. Prepared. Primed. And painted. All in about a day. Fence looks brand new. This job would have taken me a week-and-a-half and about three bottles of Aleve and not have been nearly as nicely done. Good job, guys!"

"Jeremy with RSJ was professional and helpful from start to finish. With helping choose colors with my wife to ideas of how to white wash or exterior brick. He kept us informed every step of the process and even help with some dry rot we had. The end result was a 10 out of 10. We had our entire exterior painted, including our gutters, garage door and even white washing the brick around the front and chimney. The price was amazing as well. I got 4 estimates and I am stoked I chose RSJ. They did such a great job we had him do an entire wing of our office that we remodeled. Highly recommended!!!"

Pressure Washing questions, answered by experts

Yes, pressure washers can remove rust stains from concrete. However, when coupled with an acid treatment, they can be even more effective. Just be sure to use a minimum of a 15-degree nozzle to prevent damage to the surface, and users must also be careful not to get in the way of the pressure washer’s jet as they can cut through skin and cause injury. 

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.

You can put a gentle cleaner such as distilled white vinegar, dish soap, or a degreaser in your pressure washer in a detergent injector. The attachment will mix your detergent with the water and spray it out. If you have stubborn stains on your driveway, a gentle cleaner in the attachment can help dissolve and remove those stains. Rinse the area with the pressure washer.

Even at the lowest setting, there’s always a risk that pressure washing might damage your shower or tub. Never use this technique if there’s pre-existing damage in your shower or tub, like peeling caulk, sealant, or cracked tiles. And skip this method entirely if there are any wood features present.

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.
