"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!"

"Recently, Francisco and his crew did an amazing job restoring my house after suffering smoke, ash, and soot damage from the fire. We love how the job turned out, very pleased. Francisco was excellent to work with and was on the job site daily. Issac did an amazing job power washing the soot and dirt covered house, worked all day on it. The crew paid special attention to prep work, were respectful of our property, and cleaned up daily. The crew were professional and easy to work with, they worked hard all day for a week. I will be using Francisco and his crew for other painting jobs. Highly recommend. Thank you Francisco and crew for making our home fresh again. 😊👏🏻👏🏻"

"While they are a little on the pricier end of things, I have to say that I am more than pleased with the power wash, bleach and preserve that the crew did on fence and pergola. When they were done it was like they were brand new! Highly recommended!"

"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, acid washing can change the appearance of the original brick stain color. It removes dirt, and efflorescence, often revealing the brick's original color and restoring its natural beauty. However, if not done carefully, it can also cause slight variations in color due to the cleaning process.

Yes, you can, but you’ll need to acquire the right pressure washer tips and cleaning solutions for the job. In particular, you’ll need tips that are capable of lowering the pressure from a max of 3,500 PSI to between 150 and 300 PSI. As for the cleaning solution, look for options that are clearly marked for soft washing rather than pressure washing. 

It is possible to pressure wash your deck, but it’s usually best to leave the work to a professional for two main reasons. First, power washers are expensive, and you can avoid high upfront costs by hiring a deck washing pro instead. Second, you must be careful to use the correct setting to avoid damaging your deck material. You can only clean soft woods like pine with a wide spray and a low pressure; otherwise, the water will leave unpleasant marks on your deck. Hard woods, composite material, and metal can stand up to increasingly higher water pressures.

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

  • Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.

  • Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.

  • Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.

  • Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.

  • Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.

We don’t recommend pressuring washing clapboard siding. At high levels of pressure, a pressure washer can damage wood siding permanently. Pressure washing can also make it easier to drive water into the cracks of clapboard (which are recommended for easier drainage), causing moisture damage.

If you think your clapboard siding is so dirty it could benefit from pressure washing, we suggest contacting a pressure wash cleaning service and getting a quote on a wood siding project. Some siding manufacturers recommend never pressure washing because it can force water behind the siding.
