Leesburg runs its own water and sewer utility, and for a suspected sewer backup the Town asks residents to call Utilities before a plumber. If the Town main is clear, the blockage is in your lateral, and a plumber can clear it. Call the number on this page to be connected with a local plumber in Leesburg.

What happens when you call
If several drains are backing up, start with the Town of Leesburg Department of Utilities at 703-771-2750. On-call staff check whether the problem is in the Town main. If it is not, the Town tells you the lateral is yours to clear, and that is when you call the number on this page. You are connected with an independent plumber who serves Leesburg. Be ready to describe which fixtures are slow, whether water reached the floor and where your cleanout is. On site, the plumber runs water to see how the system reacts, opens the cleanout or a fixture and clears the line with a cable or jetter.
What affects the cost
- Scope: one sink versus the main line serving the whole house
- Access: a reachable cleanout versus pulling a toilet or working through a finished basement
- Method: basic cabling, root cutting, hydro jetting or a camera inspection
- Findings: a crushed, sagging or separated section turns cleaning into repair
- Timing: evenings, weekends and holidays usually cost more
Local conditions in Leesburg
Leesburg is the Loudoun County seat, founded in 1758, with a historic downtown ringed by subdivisions built mostly in recent decades; the median home dates to 1993. Downtown houses are where a plumber is more likely to find older cast iron or clay, while the newer neighborhoods tend to clog because of grease, wipes and hair rather than worn pipe.
The Town says the resident is responsible for the entire sanitary lateral from the house to the main, even where part of it runs under public property. Town water is moderately hard, typically 100 to 150 ppm, which can help soap film build up in tub and shower lines over the years. The Town also serves some customers outside its limits, so service near the edges varies by address; check your bill.
Before the plumber arrives
- Stop running water if more than one drain is affected
- Note whether the Town has already checked its main
- Find the cleanout, usually a capped pipe in the basement or by the foundation
- Clear space around the affected fixtures and the floor drain
- Write down when the trouble started and anything flushed recently
Clearing a clog needs no permit. For pipe replacement, permits come from Loudoun County Building and Development after a Town zoning permit.
