We usually get our walkways, small front patio, and back patio sprayed down twice a year. We love using our outdoor areas when it's not too hot out. We have used some different companies over the years, but EZ Clean has been our go to for the last 2 years running. They always answer or respond back and show up when they say. Nice work and prices. My husband always asks to add in an extra mat or chair and they never seem to mind. Or charge! Thanks!
