A slab leak in Springfield is a supply or drain pipe leaking in or under a concrete floor, often the lower level of a split-level or a basement slab in one of the area's postwar subdivisions. Fairfax Water serves most of the area, and the plumbing on the house side is the owner's. Call the number on this page to be connected with a local plumber in Springfield.

How the call works
You will be connected with an independent plumber who serves Springfield. It helps to report what the meter did with all water off, which floor is affected, and whether the trouble seems tied to hot water, cold water or a drain. Expect the plumber to confirm the leak with a pressure test and then pinpoint it with listening or thermal equipment before any concrete is cut.
What affects cost
- How long the leak takes to locate
- Whether the fix goes through the slab or reroutes around it
- Flooring and finishes on the lower level
- Damage to drywall and framing from a leak that ran for a while
- Permits from Fairfax County Land Development Services, which lists permits for new, repaired or relocated plumbing fixtures
Springfield housing and water
Springfield grew from about 1,000 residents in 1950 to more than 25,000 by 1970, so much of the housing dates from the postwar and 1960s-70s building boom; the median home was built around 1974. Split-levels and ramblers from that era often have a lower floor poured on grade, with copper supply lines and cast iron or early plastic drains under it. Decades of use, past renovations and pipes resting against stone are common reasons those buried runs give out.
In everyday use, Springfield means ZIPs 22150 through 22153, which also cover North Springfield, West Springfield and Newington Forest. Fairfax Water serves most populated parts of the county, so check your bill to confirm your provider. Its supply is moderately hard and disinfected with chloramines most of the year. For water breaking out at the street or meter, Fairfax Water's after-hours line is 703-698-5613. On the sewer side, Fairfax County makes the property owner responsible for the private lateral from the house to the county sewer, including the connection.
Before the plumber gets there
- Do the meter test and record both readings
- Find and test the main shutoff
- Pull carpet back from a damp corner if you can do it safely
- Note whether the dampness changes after showers or laundry
- Take photos for your insurer
- Clear access to the water heater and the main shutoff so the plumber can isolate the hot and cold sides quickly
