In Pfafftown, a slab leak is a supply pipe leaking beneath a concrete floor, and depending on your address the clue may be a climbing water bill or a well pump that won't rest. A plumber confirms the leak, pinpoints it and repairs the line through the slab or reroutes it overhead. Call the number on this page to be connected with a local plumber in Pfafftown.

How do I check for a hidden leak if I'm on a well?
Pfafftown is an unincorporated community in northwest Forsyth County, and much of it was annexed into Winston-Salem or Lewisville, especially in 2006. Homes may be on Winston-Salem/Forsyth County Utilities water or on a private well permitted by Forsyth County Environmental Health, depending on the address.
With a well there's no meter to read, so watch the pressure tank and pump instead. Turn off every fixture, note the gauge and listen. If the pump starts or the needle drifts down with nothing running, water is escaping. A pump that cycles like that wears faster, so it's worth acting soon. On public water, the meter test is simpler: read it, wait an hour without using water and read it again.
Does it matter whether I'm in Winston-Salem, Lewisville or the county?
For permits, no. The joint Winston-Salem/Forsyth County Inspections Division serves Winston-Salem, unincorporated Forsyth County and Lewisville, so every part of Pfafftown goes through the same office. It matters more for water service: if you're on the public system, Winston-Salem/Forsyth County Utilities is the provider, and its 2025 report shows soft, chlorinated water. The utility doesn't publish where its part of the service line ends, so confirm before assuming who covers a leak near the meter.
Are Pfafftown houses old enough for buried pipe to fail?
Many are. About a third of homes in ZIP 27040 were built before 1980, according to Census survey data, and the area mixes older rural houses with newer subdivisions. Copper laid under a slab can wear through over decades where it touches concrete or gravel, and newer homes aren't immune if pipe was nicked during construction. Older rural houses on crawl spaces are less likely to have a true slab leak, though a slab addition or garage can still hide a buried line.

Tell the plumber up front whether you're on a well or public water and whether the house is a full slab or a crawl space with a slab section. Those two answers decide how the leak gets tested and how much of the floor may need to be opened.
