Ashburn is unincorporated Loudoun County, and its homes get public water from Loudoun Water. When the buried pipe between the meter and your house leaks, a plumber can locate the leak and repair or replace the line. Call the number on this page to be connected with a local plumber in Ashburn.

Do newer Ashburn homes really get water line leaks?
They do, though usually for different reasons than in older suburbs. Ashburn grew from farmland into planned communities such as Ashburn Farm, Ashburn Village, Broadlands and Brambleton, and only about 2% of homes in ZIP 20147 predate 1980. That means the pipe itself is seldom worn out. Leaks tend to come from fittings, joints disturbed when the ground settled after construction, irrigation installs, fence posts, deck footings or new trees planted on top of the line. A leak can also be on the house side of the shutoff, which the plumber will check before digging.
Is lead a concern here?
Loudoun Water states it has no lead service lines in its system, and its inventory, accepted by the Virginia Department of Health, lists none. On a home built in the last few decades, your side of the line is most likely copper or plastic. That makes the decision mostly about the condition of the pipe and where it failed, not about removing lead. Loudoun Water treats Potomac River water at its Trap Rock facility, with Goose Creek reservoirs as needed, and also buys water from Fairfax Water.
Who do I call first?
If water is surfacing at the meter, in the street or at a hydrant, call Loudoun Water. Its customer relations line is 571-291-7880, and after-hours emergencies go to 571-291-7878. If the meter is fine and the wet spot or pressure drop is between the meter and the house, call a plumber. Loudoun County Building and Development handles residential plumbing permits, which are filed as sub-records of a building permit online through LandMARC or in person in Leesburg; the plumber can tell you whether your repair needs one. Also check with your HOA before digging in common areas or front lawns governed by community rules.
One local note
Winter freezes still matter in new construction. A line that rises into a garage or an unheated utility area can split on a hard cold night, so insulating exposed sections and the hose bib connection is worth the small effort. If a leak shows up right after a freeze, shut the main valve before you go looking for it, and keep an eye on the ceiling below any line that runs through a garage wall.
