Sterling is unincorporated Loudoun County, where Loudoun Water provides public sewer within its designated service areas; the drain line from your house to that sewer is private plumbing. A sewer camera inspection films that line so roots, cracks, sags and buildup can be seen and located. Call the number on this page to be connected with a local plumber in Sterling.

Signs to act on
- Several drains slow at once, especially on the lowest level
- Toilets bubbling while the tub or washer drains
- A floor drain or basement shower taking water
- A sewer smell outside near the cleanout
- Clogs that return a few weeks after cleaning
A single slow fixture usually means a local clog. When the whole house is affected, the main line out to the street is the place to look. Filming it before any digging keeps the repair as small as the problem allows.
Local conditions in Sterling
Sterling is an established suburb next to Dulles International Airport that began with the early-1960s Sterling Park development on former farmland, and it now stretches along Route 7, Route 28 and Sterling Boulevard. Its housing is older than most of Loudoun: about 43% of homes in ZIP 20164 were built before 1980, with the largest groups from the 1970s and 1980s. That mix means the camera may find anything from clay or cast iron with root intrusion and scale to plastic with sags and separated joints.
Loudoun Water provides public water and sewer to county residents outside the incorporated towns, within its service areas. Its after-hours emergency line is 571-291-7878, and customer relations is 571-291-7880. The Sterling postal area reaches beyond the census-designated place, so if you are near the edge, check your bill to see who provides sewer.
What affects cost
- Cleanout access versus going in through a toilet or vent
- Clearing standing water, roots or grease before the camera can see
- Length of the run and the number of turns
- Locating the defect from above and saving the video
- Older Sterling Park lots where additions, sheds or patios sit over the line
What happens when you call
You are connected with an independent plumber who works in Sterling. Mention roughly when the house was built, which fixtures are affected and when the line was last cleaned. After the inspection, you will know whether cleaning is enough or whether a section needs repair. Repairs that replace pipe need a permit from Loudoun County Building and Development, applied for online through LandMARC, and the plumber normally takes care of it.
