I used Sparkle tech the first time in 2014! I used a living Social coupon and was very very impressed with their work and their employees!! We decided to use them again in March and before we called they had sent us a reminder and included the annual amount quoted to us the year before! I called and the lines were busy so I left a message. They called back within 5 minutes!! Great customer service!! I scheduled an appointment and to my surprise the company owner came cleaned all my windows inside and out, but that wasn't all he cleaned all the window runners and all my mirrors in the bathrooms and bedrooms! Very Very professional very friendly and very helpful! Great price! I recommend Highly!
