Home Improvement Contractors in Harrisburg, IL

The median home in the city of Harrisburg was built in 1968, older than the U.S. median of 1980 and older than the Illinois median of 1971. That is older than the Saline County median of 1971.¹ 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: 70% of Harrisburg's housing units were built before 1980 (U.S. 50%), and only 7% since 2010. The largest single share, 28%, dates from 1940-1959. That makes it much the same age as Saline County as a whole (66% built before 1980).¹ On houses from the 1940s and 1950s, contractors routinely check for original cast-iron drains, two-wire electrical and undersized panels before pricing a remodel.

Mobile and manufactured homes are 11% of units.¹ A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units. 62% of occupied homes in Harrisburg are owner-occupied, below the Illinois share of 67%.¹
