It’s recommended that you pressure wash your house every few years. A good pressure wash can change an unattractive, dirty home into a clean, attractive one.

If you are going to tackle it yourself, some strict guidelines have to be followed to do a good and safe job.

Pressure washers use a high-pressure water spray according to specific material. The power of water measures pounds per inch (psi). For painted wood siding and aluminum siding, the best power is 1200 to 1500 psi. This pressure is not recommended on hardboard & other material that could easily break with the pressure of water.

These are a few instructions that we advise you to follow when preparing to pressure wash a house:

  • Always wear eye protection equipment. It protects you from dust and other material during working.
  • Avoid ladders while pressure washing because the kickback of the maximum pressure of water can cause you to lose control and you may fall.
  • Be aware of power lines that are above the ground level. Be very careful about this because it can be dangerous if a line breaks or gets damaged due to the water pressure.
  • Water and electricity should not be mixed. It’s recommended that you turn off all electric supply to your house leaving only one outlet for the pressure washing equipment.
