Home Improvement Contractors in Lake Geneva, WI

The median home in the city of Lake Geneva was built in 1978, about the same as the U.S. median of 1980 and newer than the Wisconsin median of 1975. That is in line with the Walworth County median of 1977.¹ About 53% of Lake Geneva's housing units were built before 1980, close to the national share, and 13% since 2010. The largest single share, 24%, dates from 1960-1979. That makes it much the same age as Walworth County as a whole (54% 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 homes in Lake Geneva are older than rentals: a median build year of 1974 against 1988.¹ Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap.

Lake Geneva has a mixed housing stock: 52% detached houses, 8% attached or townhouse units and 31% in buildings of five or more units.¹ Owners and renters are roughly balanced in Lake Geneva, with 55% of occupied homes owner-occupied, below the Wisconsin share of 68%.¹ The median owner-occupied home in Lake Geneva is valued at $343,800 (ACS), above the Wisconsin median of $266,500. Within Walworth County the median is $302,700, so Lake Geneva sits above it.¹ Home values above the state median tend to support fuller scopes; the written scope should still separate must-do from nice-to-have.

Winters are long: the Kenosha Rgnl Ap station averages 135 nights a year at or below 32°F and 60 at or below 20°F.^2,3 Long winters put freeze-thaw, ice dams and snow load at the center of roofing and masonry decisions. Summer heat is moderate: about 11 days a year reach 90°F.^2,3 Annual precipitation is about 32 inches, with 7 days a year bringing an inch or more.^2,3

Heating dominates the year: about 6,447 heating degree days against 722 cooling degree days (base 65°F).^2,3 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope.
