Gutters
Gutters in Jefferson County
What Jefferson County means for your gutters.
Gutters in Jefferson County carry about 40 inches of rain and melted snow a year; an overflowing gutter sends that water toward the foundation. Winters in Jefferson County are among the snowier in Wisconsin, and ice dams form where gutters stay clogged.
Windows

It depends on their age. The typical home there was built in 1974, and 58% were built before 1980. Original windows, siding and roofs on older homes are often worn or drafty, so it pays to have them checked.
