I don't remember how I found A1 The Clear Choice but I have used them for years to clean the windows in my 40 windowed house. They are always professional in their reliability and completion of work. Now they are my go-to people for gutter cleaning; after this last storm the gutters overflowed and they were there within a day to clean them out. I now have a note in my calendar to have them come every 12 months before the rain does!
