The International Window Cleaning Association was formed by a group of window cleaners in the late 80s in an effort to promote safety and education as well as to enhance professionalism throughout the industry. WHY HIRE AN IWCA MEMBER COMPANY? An IWCA Member Company is the Standard in Education, Safety, Research, Insurance Coverage and Protection, and Professionalism. When a customer hires an IWCA Member, they know they are getting the best of the best. Hiring any company outside of the IWCA Membership is taking a risk. A risk of OSHA fines shared with the contractor as the business owner or homeowner, and a risk of inadequate coverage to protect your home or business from damage.
