While it can be tempting to take pressure washing into your own hands, there are many risks and pitfalls involved with DIY pressure washing. Without training and special high-powered equipment with a wide range of settings, it can be very easy to make simple mistakes that turn disastrous fast, with results anywhere from property damage to physical harm to yourself.
Hiring a pressure washing expert might be a little bit expensive upfront, but that investment in training and excellence means you're far more likely to get satisfactory work and less likely to fall prey to expensive property damage from unsafe pressure washing techniques. Overall, professional pressure washing gets you the results you want quickly and safely.
