When to clean gutters in Lansdowne

The first fall frost comes around October 26 in a typical year here, and the last spring frost around April 13 (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 Lansdowne rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Lansdowne the five-minute rain expected about once in ten years falls at 6.52 inches an hour (NOAA Atlas 14 Volume 2). At that rate one 2-by-3-inch downspout drains about 1,100 square feet of roof and one 3-by-4-inch downspout about 2,210, 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 Lansdowne

Half the homes in Lansdowne were built by 2005, 2% before 1980 (ACS 2020–2024). With homes this new, the gutters are usually the builder’s originals; keeping them clear matters more than replacing them.

76% of households own their home, and 33% of homes are detached houses, 27% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.

Hiring in Virginia

Virginia requires a Board for Contractors license for any contract over $1,000; gutter work on a home falls under the home improvement specialty (HIC) or the residential building classification. Ask for the license number and class, and look it up before signing.
