Experience, Value, and a 100% Guarantee. COIT began offering cleaning services in 1950 as a small dry cleaner, located near COIT Tower in San Francisco, California. Shortly after opening, founder Lou Kearn offered something new - drapery cleaning backed by a 100% Best Carpet Cleaner Satisfaction Guarantee. As a result, his small business flourished and many more cleaning services were added. Proud of the tradition started by Lou, all of COIT's cleaning services are still backed by that same guarantee. Today, COIT is one of the largest specialty cleaning & restoration companies in the world with franchises in the United States, Canada and Thailand. We have more than 50 years of experience in the industry, yet we have remained a family-owned business with a close-knit corporate culture. COIT's experienced team of corporate and franchise business leaders are passionate about earning the trust of its home, business and insurance industry customers by providing a continually expanding list of value-driven cleaning and restoration services. At COIT, we are committed to making the world a cleaner, healthier, happier place - and it shows!
