When to clean gutters in Onset
The first fall frost comes around October 24 in a typical year here, and the last spring frost around April 21 (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.

Gutter and downspout size for Onset rain
The short, hard downpour is what a gutter is sized for. In Onset the five-minute rain expected about once in ten years falls at 6.88 inches an hour (NOAA Atlas 14 Volume 10). At that rate one 2-by-3-inch downspout drains about 1,050 square feet of roof and one 3-by-4-inch downspout about 2,090, 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.
The houses in Onset
Half the homes in Onset were built by 1938, 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.
89% of households own their home, and 79% of homes are detached houses, 9% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
