When to clean gutters in Potomac
The first fall frost comes around November 6 in a typical year here, and the last spring frost around April 1 (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 Potomac rain
What overwhelms a gutter is a burst, not a season. In Potomac the five-minute rain expected about once in ten years falls at 6.66 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 1,080 square feet of roof and one 3-by-4-inch downspout about 2,160, 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 Potomac
Half the homes in Potomac were built by 1977, 57% 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. 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.
85% of households own their home, and 70% of homes are detached houses, 15% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
Hiring in Maryland
Maryland requires a Maryland Home Improvement Commission license for home improvement work of any amount, gutters included, and a contractor may not take a deposit of more than one third of the contract price (Business Regulation § 8-617). Look the license up before signing, and keep the deposit to one third or less.
