Window Washing services clearly improve your view of the world and your facility. At Offshore Janitorial window washing is one of our specialties, we use many techniques to achieve great window washing results. Other than the conventional wand and squeegee system, Offshore Janitorial uses a d-ionized water system to clean the exterior of buildings. This system allows us to clean around a building at a good pace without damaging the landscape. Our window service includes removing hard water deposits on glass which is usually caused by sprinklers.
