Worth every penny! When I arrived home after my windows had been cleaned, I thought the glass from my windows had been removed...that's how spotless the windows were. I don't know how they do their magic, but Superior Window & Gutter is top-notch when it comes to cleaning windows and skylights. Superior's owner, Steve Howell, describes his company as his "baby" and I can testify that he takes his service and reputation very seriously. Steve has handpicked a professional, courteous, friendly, staff that knows what it's doing. Kudos to you for making my house glisten!
