Most Kernersville sump pump calls trace back to a float that won't lift, a check valve that leaks back, a tripped outlet or a motor at the end of its run. A plumber can test each part, fix what failed and point the discharge where it belongs. Call the number on this page to be connected with a local plumber in Kernersville.

What happens after you call
The number connects you with an independent plumber who works in Kernersville. Expect a few questions first: is water rising right now, where the pit is, how old the pump is and what it's doing (silent, humming, cycling or running nonstop). On site, the plumber will usually check power to the outlet, lift the float to see whether the pump starts, watch a full cycle and listen for water dropping back through the check valve. They'll also follow the discharge line to see where it ends. If the pump is beyond repair, you'll talk through replacement size and whether to add a backup.
What affects the price
- Whether one part (float, switch, check valve) or the whole pump needs replacing
- The pump's horsepower and housing material
- Crawl space height and how easy the pit is to reach
- Rerouting a discharge line that ends at the foundation or in a drain
- Adding a battery or water-powered backup or a high-water alarm
- Whether the job needs a permit
Kernersville specifics
Kernersville's housing is mostly 1980s to 2010s, with a median build year of 1995, and about 26% of homes predate 1980, according to Census survey data. The older ones are concentrated around the historic downtown, near Korner's Folly and the South Main Street district. A pump in a newer subdivision may be the original one installed by the builder and never tested since.
The Town of Kernersville has run a sewer system since the 1920s. That system is there for household wastewater, so a sump line tied into a laundry drain or cleanout should be rerouted to drain outdoors. Water comes from Winston-Salem/Forsyth County Utilities, whose cross-connection program makes owners responsible for installing, testing and maintaining backflow assemblies. Ask how that applies before adding a water-powered backup, since it draws on the drinking water line.
Unlike most Forsyth County towns, Kernersville issues its own plumbing permits and inspections through the town's Development Services Division and its ViewPoint online portal, not the Winston-Salem Inspections Division. If the job includes a new circuit, a new pit or drain changes, the plumber can tell you whether to file there.
Before the plumber gets there
- Unplug the pump or switch off its breaker if water is near the outlet
- Clear a path to the crawl space door or basement stairs
- Find the pump's label or receipt if you have it
- Note where the discharge pipe exits the house
- Move stored items away from the pit
