How to pressure clean a house (Top Dos and Don’ts)

Thinking about pressure cleaning? Well, if you’re thinking about getting pressure cleaning done on your property, then chances are that you know it’s dirty and you might even have mold somewhere.

Ideally, the pressure cleaning job is pretty straightforward and involves nothing but some light pressure cleaning of the driveways, sidewalk, and maybe patio. 

However, sometimes the job gets a little more complicated and we want to go ahead and pressure clean the actual house. 

Well, there’s a couple of dos and don’ts that you should take into account when pressure cleaning your home. 

How to Pressure Wash Your House

Don’ts:

  • Make sure to avoid all electrical outlets, panels, and boxes. This should go without saying, but water and electricity do not match well. You’re going to want to cover these areas up with some inexpensive plastic covering and tape to make sure that water doesn’t get in. Otherwise, just make sure to be very careful and you shouldn’t have any problems or cause any unwanted shortages that could result in hundreds of dollars of electrician repairs. 
  • Don’t use any harsh chemicals other than light bleach. You’re going to want to stay away from using any harsh chemicals on your walls. There’s tons of chemicals for sale that are completely unnecessary and often do more harm than good. If you find that you have some stubborn stains, consider using some bleach to weaken the stains (or mold) and perform a deeper clean. 
  • Don’t get the nozzle too close to the wall. If you’re using a pressure washer, that pressure washer is going to have, well, pressure. If you get too close to a wall, you could potentially damage the stucco and need to do some additional repairs. Make sure to be careful here. 

Dos: 

  • Make sure to be thorough when it comes to dirt.  If you’re pressure cleaning the walls, make sure to be thorough and take off all the dirt, even if that means using some light bleach. If you’re pressure cleaning the walls, you might also be interested in getting some painting done because there’s a potential for paint to peel off. The cleaner the wall, the better the application of primer and paint will be when it’s time for the new, fresh coat of paint. 
  • Make sure to wear eye protection. You might take this for granted, but things are going to be flying at your eyes at some point- I can guarantee it. When you’re shooting water at hundreds of PSI at surfaces with loose objects, you’re going to see some of those objects fly. I can’t begin to talk about how many times I’ve found myself with stucco in my eyes because I decided that I wasn’t going to wear goggles. 
  • Work your way down. I hope that when you shower, you start with your head first. The same principles apply here. If you start pressure cleaning towards the bottom of a wall, when you finally make your way towards the top, you’re going to find that all of that dirt and grime will make its way down- dirtying everything that you’ve already cleaned. Start by cleaning horizontally from top to bottom with a decent width nozzle and you should be fine.
