Home Improvement Contractors in Irmo, SC

The median home in the town of Irmo was built in 1985, newer than the U.S. median of 1980 and older than the South Carolina median of 1992. That is older than the Richland County median of 1989.¹ Irmo's housing is newer than the national mix: 36% of units predate 1980 against 50% nationally, and 20% date from 2010 or later. The largest single share, 38%, dates from 1980-1999. That makes it much the same age as Richland County as a whole (38% built before 1980).¹ A large share of newer homes means many systems are still inside a warranty; checking that comes before any repair quote. Owner-occupied and rented homes in Irmo are of similar age: median build years 1985 and 1983.¹

Housing in Irmo is mostly detached single-family: 92% of units, with 3% 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 Irmo: 82% of occupied homes are owner-occupied, above the South Carolina share of 72%.¹ The median owner-occupied home in Irmo is valued at $203,400 (ACS), below the South Carolina median of $259,000. Within Richland County the median is $242,800, so Irmo sits below it.¹ With values below the state median, phased scopes - the essential work first - are a common way to keep a project sensible.
