Home Improvement Contractors in Swansea, IL

The median home in the village of Swansea was built in 1993, newer than the U.S. median of 1980 and newer than the Illinois median of 1971. That is newer than the St. Clair County median of 1975.¹ Most of Swansea's housing is recent: only 32% of units predate 1980 (U.S. 50%) and 14% were built since 2010. The largest single share, 31%, dates from 1980-1999. That makes it an older stock than St. Clair County as a whole (55% built before 1980).¹ On houses from the 1980s and 1990s, polybutylene supply lines, builder-grade windows and first-generation openers are the usual items a contractor confirms before quoting. Owner-occupied and rented homes in Swansea are of similar age: median build years 1993 and 1994.¹

Housing in Swansea is mostly detached single-family: 70% of units, with 12% in buildings of five or more units. Mobile and manufactured homes are 9% of units.¹ A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units. 73% of occupied homes in Swansea are owner-occupied, above the Illinois share of 67%.¹ The median owner-occupied home in Swansea is valued at $223,600 (ACS), below the Illinois median of $263,300. Within St. Clair County the median is $180,300, so Swansea sits above it.¹ With values below the state median, phased scopes - the essential work first - are a common way to keep a project sensible.

Summers run hot, with about 53 days a year at 90°F or more and 2 at 100°F.^2,3 A long hot season shortens the life of roofing, sealants and garage-door electronics, and it shapes what a contractor specifies.
