In 1981, Knight’s Plumbing Co. was started by Dennis Knight, as owner and operator, and his wife Vonnie, as office manager. The company has always been family-oriented, giving personalized service and building positive relationships with each customer, over the past 30 years. With a foundation built on providing quality work at reasonable prices, Knight’s Plumbing Co. has been able to establish itself as one of the most honest and reliable plumbing companies in the Columbia, South Carolina, area.

In January of 2010, their son Kenneth took over as the new owner and incorporated the business. He has continued to provide the quality service everyone expects from Kight's Plumbing Co.
