Hello there Evansville, Newburgh, and Henderson friends! We frequently have questions about the proper way to power wash a home or building, so we decided to add a blog entry to cover some of the basic answers. When deciding to pressure wash a house, there are multiple factors to consider:

1. Will you hire a professional, or attempt to do it yourself?
2. What is the risk/reward ratio with the decision you make?
3. Do you have the proper equipment to complete the task?
4. What is the best method to safely pressure wash a house or building?
5. What are the proper detergents for the surface material that will be cleaned?


     Well, there's alot to answer just in these basic questions, but let's address them briefly. For question #1, the answer isn't necessarily as easy as it may appear. Some homeowners prefer the DIY method for exterior cleaning projects, but pressure washing isn't as simple a some may think. For instance, we frequently see homeowners that go the DIY route up on a ladder attempting to wash a second story section of house. Did you know that with our professional equipment, we can reach up to 4 stories or higher from the ground? This is advantageous because it allows us to remain safe while still maintaining our stability. If you don't have the proper equipment, and your property is more than one story, the best decision may be to hire a professional power washing company. This parlays into a similar answer for question #2.
     For question #3, you must consider the most important factor in TCU (total cleaning units): Gallons Per Minute (GPM). While many think that pressure is the pertinent factor in cleaning efficiency, pressure doesn't actually clean organic growths such as mold, algae, whiskey fungus, etc. Gallons Per Minute creates a flow that is adequate enough, and the most effective method of cleaning when combined with the proper detergents. Which segues in to question #4....
     The best method for pressure washing a house or building is the SoftWash, which we introduced to the tri-state over a decade ago. The SoftWash utilizes an ultra low pressure application of delicate detergents and algaecides to neutralize all organic growths, followed by a gentle rinse, normally using <100 psi.Very rarely will high pressure be necessary. If a contractor plans to use a high pressure washing method to clean your home, you will want to seek out a safer option. You can get a

     Finally, question #5: The proper detergents and chemicals for power washing will vary from surface to surface, and also whether or not the growths are organic, environmental, atmospheric, or chemical. This is the area where pressure washing gets very tricky to the untrained, and why we recommend hiring a professional pressure washing contractor. You can waste a substantial amount of money, along with the risks of chemical interactions and dangers.
