We are very satisfied with the window washing service from Markatos. First, they were able to do the windows before May 16 even though I only contacted them on May 8. My former window washing guy could not even though we were regular customers. Michael did an estimate that was a little less than my former window washer charged. The crew was professional, personable and did an outstanding job on the windows in about 90 minutes. Markatos is my new window washing service!
