When to clean gutters in Towson

The first fall frost comes around November 7 in a typical year here, and the last spring frost around April 2 (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 Towson rain

What overwhelms a gutter is a burst, not a season. In Towson the five-minute rain expected about once in ten years falls at 6.64 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 2,170, 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 Towson

Half the homes in Towson were built by 1965, 69% 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.

56% of households own their home, and 33% of homes are detached houses, 22% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.

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.
