Get matched with top pressure washers in Rolla, ND

The amount of pressure required to wash your siding depends on the material. Vinyl siding, as well as brick and stone exteriors, can handle high pressure of 2,500 to 3,000 psi, especially if you’re not worried about damaging paint. Wood and aluminum siding needs a gentler approach and shouldn’t face more than 1,500 psi.

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. 

If pressure washers are stored in freezing conditions and aren’t pretreated for such temps, any liquid remaining in the water pump may freeze, expand, and severely damage your machine. While often recommended, emptying the machine with compressed air is a long and tedious process and still may not completely drain the liquid in this pressure washer part. But adding a bit of antifreeze instead will keep it in tip-top shape without the extra effort.

Experts agree that spring and fall are the best times to pressure wash a home’s exterior due to the mild weather. Line up a pressure washing project once every year, anywhere from March to November, for the best results. This will vary by location, but aim for a warm, dry season, whenever that may be in your climate.
