Things You Should NEVER Pressure Wash

Pressure washing can do wonders for your home, but there are things you need to avoid! As much good pressure washing can do, it can also do an equal amount of harm if you aren’t utilizing it properly. Here are some things you should never pressure wash.

Things You Should NEVER Pressure Wash


Wood Siding

Okay, so it is possible to correctly pressure wash wood siding, but you have to make sure that you use the correct water pressure. If your water pressure is set too high, you run the risk of water being forced up and under the exterior surface. Water getting under the siding can damage your insulation and wiring and even cause mold to grow. For wood siding, as well as aluminum and vinyl siding, softwash is the name of the game.

Electrical Panels and Meters

DO NOT pressure wash any fixtures that house electricity, even ones that are on your home’s exterior. These fixtures are built to withstand a rain storm, not high pressurized water. This can cause damage that is very costly to repair. 

Asphalt Shingles

If you have asphalt shingles on your roof, do not pressure wash them. Pressure washing your shingles will strip away the protective granules, leaving your roof much more vulnerable to weather wear and damage. Also, pressure washing in a high place is very dangerous because of the recoil of the wand. 

Air Conditioners

Pressure washing an air conditioning unit can bend or crush the fins, restricting airflow and destroying the unit. We recommend straightening the cooling fins using a butter knife and using a vacuum to clean your unit. You can use water to rinse away the debris, but it should be a very gentle water flow. 


We strongly advise against using a pressure washer to clean the inside of your gutters. The best way to rid your gutters of debris is by hand and then rinsing out the inside with a garden hose. Like electrical panels, these gutters are only meant to withstand a rainstorm, not high pressurized water.
