Pressure washing is a great way to clean your home, driveways, pool deck, windows, and decks. This is a highly effective time saving method of cleaning. There are several things you need to take into effect when you decide you are going to begin a project. Make sure you read the user manual for your pressure washer. If you are familiar with pressure washing you can most likely skip that step. I just recommend that you wear proper safety equipment on your person. Also keep in mind that a pressure washer is exactly that, a pressure washer. That means it will break things if you aren’t careful, so make sure you keep you wand a safe distance away from windows or other breakable items. Even more importantly keep it away from your skin as it will cut through your flesh.
Learning to use a pressure washer has so many benefits. Not only can you practically clean the whole exterior of your home for practically nothing you can also start your own pressure washing business. Most pressure washing contractors charge anywhere from 50 -75 dollars an hour. This may seem like shitty work but it really isn’t. Once you get good with a pressure washer it is more like an art. When I was pressure washing charlotte I was working 10 hour days and making two to three thousand dollars a day depending on the jobs for the day. 
When looking for pressure washing equipment make sure you get a warranty on the equipment especially on the pumps. The pumps on a pressure washer is the weak point of the pressure washer. They have a tendency to go out on people. A warranty is essential in my opinion. Also when you are using your pressure washer, if it is on and running make sure you have water cycling through the machine the whole time. If you fail to do that you can burn your pump up pretty quickly.
If you decide that doing it yourself is not the route you want to take you can google pressure washing services and find tons of pressure washing contractors in your area. I would recommend finding a contractor with a business license and make sure they are insured and bonded just in case something happens like a broken window.
