Kenneth Turnage II is owner of K2GC.

K2GC is a general contracting firm that provides East Bay homeowners with home remodeling services, repairs, maintenance programs, kitchen and bathroom design, water and fire damage restoration, and emergency repairs and tarping.

Owner Kenneth (Kenny) Turnage II has been in the construction industry for more than 25 years. He spent many years in his family’s construction business, holding positions ranging from project foreman to Chief Operating Officer. In 2000, Kenny earned his general contractor’s license and started K2GC soon after.

K2GC understands the importance of protecting clients’ homes, so it diligently inspects them for potential problem areas and recommends improvements that “can keep little issues from becoming big expenses,” says Kenny. This detailed approach to customer service extends to other areas—when a home is damaged by water or fire, K2GC can negotiate with insurance companies and handle repairs at the same time. For those looking to update space, the company can provide expert design and remodeling services.
