Gutter cleaning, repair and new gutters in Mukwonago, WI

When to clean gutters in Mukwonago

The first fall frost comes around October 10 in a typical year here, and the last spring frost around May 5 (median dates, NOAA normals). Plan the fall visit for after the frost, when the trees over the roof have finished dropping, and the spring visit for after the pollen and catkins.

When to clean gutters explains how the trees over a roof change the schedule.

Gutter and downspout size for Mukwonago rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Mukwonago the five-minute rain expected about once in ten years falls at 7.04 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 1,020 square feet of roof and one 3-by-4-inch downspout about 2,050, by the rule in the Copper Development Association’s design handbook. Try your own roof in the gutter and downspout calculator, which starts from this figure.

With about 37 inches of snow in a normal year here (NOAA normals), gutters carry ice as well as water. Ice dams start with heat from the house melting roof snow that refreezes at the edge (University of Minnesota Extension); the fix for the dam is in the attic, and the gutter’s part is to be hung strongly enough to take the weight.

Half the homes in Mukwonago were built by 1989, 38% before 1980 (ACS 2020–2024). At that age a gutter has seen decades of leaves and storms, and the fascia it hangs from has too.

74% of households own their home, and 66% of homes are detached houses, 8% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
