When using Bear Essentials, you can be certain of a fully insured service that utilises the most effective water-fed pole system that enables windows can be cleaned from a distance of up to 45 feet. This ensures no ladders are needed and, ultimately, your utmost privacy is maintained. My superior clean is achieved using pure water. Pure water is water that has been specially treated through an intensive filter system, ensuring all impurities (such as chemicals, minerals and organisms in the water) are removed. This means no residual stains, streaks or marks are left after cleaning.
