Pressure washing is an important part of maintaining your home. It also boosts curb appeal, making your home more attractive to neighbors, visitors, and potential buyers, and increasing its value over time. While it may not be necessary to pressure wash your home more than once a year, depending on the type of materials used in its construction and the environmental conditions in your area, annual pressure washing has benefits that go beyond aesthetics and valuation: it can help you maintain a healthier home both inside and out.
