Cleaning Service CT- Advantage Maintenance Inc. has been in business for over 35 years with a vision of providing the best Connecticut cleaning services while at the same time investing in our community, employees, and company. Through hard work, dedication, commitment, passion, and a team that is second to none, that vision is now a reality. We count many of Connecticut’s best and largest companies and businesses as customers and work hard to keep them happy with our service. Our clients include many property management companies as well as industrial manufacturing, entertainment, and arts venues, multi-tenant office buildings, major corporations, banks, financial institutions, medical facilities, and schools / educational buildings. Many of our “customers/partners” have also requested that we service their facilities in other states so, at their request, we have expanded beyond the borders and have now become a regional commercial cleaning service that proudly services Connecticut.
