What Columbia’s housing means for repairs
Columbia's housing mixes older homes near downtown with newer suburbs. Columbia's median home was built in 1980, about 30% of homes predate 1960 and 31% were built since 2000. About 49% are single-family detached and 46% are owner-occupied, with many rentals near the University of South Carolina.
Neighborhoods such as Shandon, Rosewood and Elmwood Park have early 1900s bungalows on crawlspaces with wood siding, plaster walls and older wiring. Newer homes spread outward on slabs and crawlspaces. Electric heat covers 72% of homes, mostly heat pumps that also handle cooling.
Weather that wears on Columbia homes
Columbia is hot and humid, with long summers that often pass 95°F. Heat pumps run hard, and humidity keeps crawlspaces and attics damp. Moisture leads to mold, wood rot and soft floors.
Termites are active throughout South Carolina, and older wood-frame homes are especially vulnerable. Heavy rain from thunderstorms and tropical storm remnants can flood low areas, as the historic October 2015 flood showed. Winters are mild, but occasional ice storms bring down trees and power lines. Spring pollen from the region's pines and oaks also clogs HVAC filters and coats screens, decks and outdoor AC coils.

Common questions
- Why is my Columbia heat pump running all the time?
In extreme heat, heat pumps run longer to keep up. Dirty filters, low refrigerant or leaky ducts make it worse. Annual service and clean filters help.
- Do Columbia homes need termite protection?
Yes. Termites are common in South Carolina, especially in older wood-frame homes. Annual inspections and treatment protect your home.
- What drives the cost of crawlspace repairs in Columbia?
The extent of moisture damage, the need for vapor barriers or dehumidifiers, and whether joists or subfloors need replacing.
