It seems every year that when the kids come home from college we are all sick within a week! This summer my friend Jennifer told me about King Of Clean and we had Robert come over and treat our home. Robert was polite and quite personable and really made us feel at ease. He was there about an hour and a half and my goodness the house immediately felt cleaner, the air was light and the pet odor was gone. We thanked him and 30 days later no one was sick. My husband and I called him back and signed up for 90 day treatments. Very impressed.
