Gutter and downspout size for Wilmington rain
What overwhelms a gutter is a burst, not a season. In Wilmington the five-minute rain expected about once in ten years falls at 6.49 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 1,110 square feet of roof and one 3-by-4-inch downspout about 2,220, by the rule in the Copper Development Association’s design handbook.

The houses in Wilmington
Half the homes in Wilmington were built by 1946, 81% before 1980 (ACS 2020–2024). In a neighborhood that age, many houses are on their second set of gutters or due for one, and the fascia board behind them is worth checking at the same visit. 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.
46% of households own their home, and 9% of homes are detached houses, 54% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
