I've used Congressional windows for many years for both inside and outsde window cleaning. The staff is thorough, considerate, and careful. Our house has windows with a variety of pedigrees (from very old and oddly situated to modern efficient models); the workers handle all efficiently. I paid about 350 for three staff to work a total of six hours. Very reasonable for the quality of the work.
