Get matched with top pressure washers in Trenton, NE

Most deck lumber is softwood that you can easily damage with the spray from a power washer. Most power washers, though, have a lower pressure setting that’s relatively safe for deck materials if you’re careful to hold the nozzle at least a foot from the surface and continue moving without hovering in one area. 

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 can get more pressure out of your pressure washer by adjusting the pressure control knob clockwise to increase pressure (+). You can also check your nozzle for debris and clogs and remove anything you find with needle nose pliers. Switch to a nozzle with a lower-degree spray angle or a turbo nozzle to achieve more pressure at the tip. Check for leaks in the hose and connections, and make sure your water supply is offering enough pressure. 

A good PSI for a pressure washer will depend on the job you're doing. Pressure washer PSI ratings range from 1,300 to 4,200 PSI. Lower PSI is suitable for cleaning dirt and debris off of softer materials. Use a low PSI when pressure washing vinyl siding , wood, or stucco. A heavy-duty job like cleaning graffiti off of concrete or brick will require at least 2,000 PSI.
