The first and arguably most vital piece of information that you need to wrap your head around over the course of a pressure washing endeavor is the PSI that you are going to be putting out of the hose portion of your overall apparatus. However, there is a mistake that people commonly make here, namely that they assume that a single PSI will serve virtually all of your needs.
There is a pretty good chance that pressure washing companies the woodlands will diversify the PSI that they set their machines at during a house washing gig. This is because of the fact that some parts of your home require a lighter touch whereas others need to be blasted into oblivion to get them even marginally clean. The truth of the situation is that you need to vary your PSI similarly, because no individual number is going to provide you with the most optimal solution that the world has to offer. You should use a 2,000 PSI and a 3,000 PSI based on whether you are cleaning windows or vinyl siding.
The fact of the matter is that anything that is soft and prone to water damage needs to be soft washed with a pressure cleaning rig. That means that using a 2,000 PSI will be more than adequate for those parts of your home. When you move on to other areas such as brick laid groundwork or some concrete pavements that surround your house, you need to take the PSI all the way to 3,000 so that they can truly get cleaned of the filth that is resting on top of them.
