A plumber in Upperville.

NOAA’s Purcellville normals, the nearest long record at Upperville’s height, put the median first fall freeze on October 25 and the last spring one on April 16, a week earlier and a week later than the Warrenton station to the south. Fauquier County builds to a 24-inch frost depth, but the pipe that freezes is rarely the buried one. It’s the run along a stone foundation, under an addition’s crawlspace, or out to a spigot on the north wall. Pull the hoses off by late October, and in a cold snap like late January 2026, prop open the cabinet under any sink on an outside wall.

FCWSA’s 2025 report lists water systems in nearby Paris and Marshall but none in Upperville, so houses here draw from their own wells. That water often runs acidic: close to half the Fauquier well samples Virginia Cooperative Extension tested fell below a pH of 6.5. Over years it can wear copper thin from the inside until a pinhole opens. Leak detection is $200 to $500 when the drip is inside a wall.

When the power goes, so does the water: the well pump runs on electricity. NOAA’s storm records show how often lines come down here, from trees and power lines in and around Upperville on August 10, 2021 to poles across Route 50 a mile west on May 20, 2026. A pump that won’t restart afterward, or a pressure tank that cycles every few seconds, belongs to a well contractor, and we’ll tell you which side of the tank the trouble is on.

Heavy rain is the other storm. FEMA maps special flood hazard areas within about 300 meters of the village center, and the County’s village plan calls the drainageway soils along Panther Skin Creek’s tributaries unsuited to drainfields, since they flood or hold a high water table. Drains that go sluggish only after days of rain mean a waterlogged drainfield, and the septic company is who you call. Slow in any weather points at the house’s own line out to the tank, and that’s ours: $550 to $1,650 to clean it, $89 to put a camera in it on the same visit.
