When to clean gutters in Galesburg

The first fall frost comes around October 19 in a typical year here, and the last spring frost around April 20 (median dates, NOAA normals). Booking the fall cleaning after the first frost, once the trees over the roof are bare, catches the season’s drop in one visit; the spring cleaning comes after the pollen and catkins are down.

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

Gutter and downspout size for Galesburg rain

The short, hard downpour is what a gutter is sized for. In Galesburg the five-minute rain expected about once in ten years falls at 7.87 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 910 square feet of roof and one 3-by-4-inch downspout about 1,830, 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.

The houses in Galesburg

Half the homes in Galesburg were built by 1953, 84% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look. On a house built before 1978, replacing more than 20 square feet of painted fascia or trim falls under the EPA’s lead-safe rule, so ask whether the crew is certified.

61% of households own their home, and 68% of homes are detached houses, 1% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
