Leesburg's basements range from old stone foundations near the historic district to poured walls in newer subdivisions, and both rely on a working sump pump when the ground gets saturated. Most failures come down to the switch, the check valve, the power supply or the motor. Call the number on this page to be connected with a local plumber in Leesburg.

What happens when you call
The number on this page connects you with an independent plumber who works in Leesburg. Expect a few quick questions: Is water rising now? Does the pump hum, click or stay silent? Is the pit for groundwater, or does it serve a basement bathroom? Is any water close to outlets or appliances?
On site, the plumber tests the pump with water, checks the float and check valve, looks at the electrical supply and follows the discharge line outside. You will hear whether a repair will hold or whether a replacement makes more sense, before any work begins.
What drives the cost
- A part such as a float switch or check valve versus a complete pump
- Groundwater sump or sewage ejector
- Pit condition, including silt, gravel or a damaged basin
- Rerouting a discharge line that runs back toward the house
- Adding a battery backup or high-water alarm
- Any permit steps for new piping
- After-hours or storm-day service
Leesburg conditions
Leesburg is the Loudoun County seat, founded in 1758, with a historic downtown surrounded by subdivisions built mostly in recent decades; the median home dates to 1993. The Town of Leesburg Department of Utilities runs its own water and sewer system, separate from Loudoun Water. The Town maintains sewer mains up to the lateral cleanout, but the resident is responsible for the entire lateral from the house to the main, even the part under public property.
If a basement drain backs up, the Town asks you to call Utilities first, at 703-771-2750 during business hours or through the Leesburg Police non-emergency line, 703-771-4500, after hours. On-call staff check the Town main before you hire a plumber for the private side.
A water-powered backup pump connects to drinking water. Under the Town's cross-connection program, testable backflow devices must be tested every year by a DPOR-certified tester and reported to the Town. For permits, the Town issues a zoning permit first and Loudoun County Building and Development issues the building permit.
Before the plumber arrives
- Shut off the basement circuit at the panel if water is near power
- Clear a path to the pit and the electrical panel
- Find where the discharge line exits the house
- Hold off on laundry and showers if a floor drain is backing up
- Take photos of any water damage for your records
