Home Improvement Contractors in James Island, SC

The median home in the town of James Island was built in 1970, older than the U.S. median of 1980 and older than the South Carolina median of 1992. That is older than the Charleston County median of 1991.¹ Older housing stock means a contractor's first job is finding what is behind the finish - wiring, plumbing and roof decking - before a price is final. The stock is old by national standards: 68% of James Island's housing units were built before 1980 (U.S. 50%), and only 5% since 2010. The largest single share, 55%, dates from 1960-1979. That makes it a newer stock than Charleston County as a whole (34% built before 1980).¹ On houses from the 1960s and 1970s, the routine checks are aluminum branch wiring, galvanized supply lines and original single-pane windows.

Owner-occupied and rented homes in James Island are of similar age: median build years 1970 and 1972.¹ Housing in James Island is mostly detached single-family: 92% of units, with 1% in buildings of five or more units.¹ A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units. Home ownership is the norm in James Island: 88% of occupied homes are owner-occupied, above the South Carolina share of 72%.¹

The median owner-occupied home in James Island is valued at $508,600 (ACS), above the South Carolina median of $259,000.
