COIT Services Columbus, Columbus

Coit Services may have started out as a small dry cleaning business in 1950, but all that changed when the founder began offering drapery cleaning backed by a guarantee. It promised everything from a re-cleaning to a complete replacement if customers were unsatisfied, and it ensured enthusiastic high-fives and repeat business. Coit Services still relies on that guarantee to this day, and as a result, the company now has locations around the country, in Canada, and even in Thailand.

Its technicians travel to homes to refresh carpets, de-grime tile and grout, and remove pollutants from air ducts. They also still perform Coit's longtime specialty service—drapery and blind cleaning.
