At Big Apple Window Cleaning, we don’t just offer commercial window washing services, we care about our clients taking the right approach to commercial property care. That’s why we’ve created this educational section of our website. Our experts write blogs related to the window cleaning business to help clients learn more about our services. We work hard to find out what our clients are interested in and do extensive research to provide answers to their questions. Squeeky Clean Commercial Window Washing offers service plans for every need in the Washington Metropolitan Area. Whether it’s weekly cleaning of your glass entry or quarterly, semi-annually or annual cleanings of the interior and exterior glass surfaces of your building, together we can develop a plan to satisfy any special requirements. We can clean the windows of buildings up to five stories using water-fed poles and de-ionized water.
