Why Columbia costs more than the rest of South Carolina
Columbia carries roughly a 3% premium over the South Carolina statewide figure. Three things drive that gap. Metro wages run above the state average, and labor is about 40% of this bill. Permitting and inspection are slower and more expensive inside city limits. And site access is tighter, which means smaller equipment, more hand work, and sometimes street permits for deliveries.
Statewide, South Carolina averages $4,284 to $9,044 installed, against $4,413 to $9,315 inside Columbia. Suburbs on the metro fringe usually fall between the two.

Permits in Columbia
A residential permit for this work typically runs around $350 in South Carolina, and metro jurisdictions like Columbia usually sit at the upper end of that range with longer review times. Permit cost is rarely included in a contractor quote, so add it separately. Confirm scope with the Columbia building department before work begins.
Hiring in Columbia
Get three written, itemised quotes from licensed and insured contractors, and make sure each specifies the same dimensions and the same grade of material. In a metro market, the cheapest bid often reflects a thinner specification or a crew travelling in from outside the area rather than a genuine saving. Ask for local references and check that the licence is current in South Carolina.
