Fairfax Station conditions
Fairfax Station began in 1851 as a stop on the Orange and Alexandria Railroad and is now a mostly residential, unincorporated community in southern Fairfax County. Its median home was built around 1982, and many are large houses on wooded lots with full basements. In those homes, the pipes most likely to be buried in concrete are the service line where it passes through the foundation, drains for basement bathrooms and wet bars, and supply lines to additions or garages.
Fairfax County lists Fairfax Water as the provider for county residents, but check your bill to confirm how your home is served. For Fairfax Water customers, the utility owns the meter, and the homeowner owns the underground service line from the meter to the house as well as everything inside. The supply is moderately hard and disinfected with chloramines most of the year, with free chlorine in spring; those are not the usual reasons a buried pipe fails. Fairfax Water customer service is 703-698-5800. Where public sewer serves the home, the property owner maintains the private lateral.
Cost factors
- Detection time in a large house with long pipe runs
- Whether the repair cuts the slab or reroutes overhead
- Finished basement flooring, built-ins and trim
- Water damage and drying
- Fairfax County Land Development Services residential plumbing permits, filed through PLUS, when required
When you call
You will be connected with an independent plumber who covers Fairfax Station. Describe what you have seen, which level is affected, how the home gets its water, and what the meter did. If water is spreading, close the main and leave it closed. Long driveways and large lots can make access slower, so mention any gate or access details up front. It also helps to know where the line enters the house and whether the basement ceiling is finished, since that shapes the repair options.
