Upon interviewing an individual or company, ask about their methods and techniques.
We use a process called soft-washing, which includes applying a light, chemical solution onto the home. After a few minutes, we’ll give the house a moderate rinse to wash away both the chemical and organic matter.
As a side-note, all plants and shrubs will receive a thorough rinse before, during, and after our wash to protect it from overspray. We are very cognizant of our surroundings and have yet to damage any landscaping.
