By heavy-rain days, McNair falls near the middle of the 375 places in Virginia on this site (11.4 a year). By the age of its homes it sits among the newest by median year built of the 373 places in Virginia on this site (half built by 2003). By first frost it falls 90th earliest for the first fall frost of the 375 places in Virginia on this site (October 24).

When to clean gutters in McNair

The first fall frost comes around October 24 in a typical year here, and the last spring frost around April 15 (median dates, NOAA normals). A fall cleaning set for the weeks after that frost, when the branches over the house are bare, gets the year’s leaves in one trip; a spring visit follows once the pollen and catkins have come down.

When to clean gutters explains how the trees over a roof change the schedule.

Gutter and downspout size for McNair rain

Gutters are sized for the worst few minutes of a storm, not for the year. In McNair the five-minute rain expected about once in ten years falls at 6.56 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 2,200, 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 McNair

Half the homes in McNair were built by 2003, 3% 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.

23% of households own their home, and 2% of homes are detached houses, 26% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.

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.
