Winston-Salem Plumbing Company: Plumbers for Winston-Salem, NC Homes

What makes plumbing in Winston-Salem different

Winston-Salem was formed in 1913 when the Moravian town of Salem and the tobacco and textile town of Winston merged, and the housing stock still shows it. Within a few miles you can find 1910s and 1920s homes in Ardmore and the West End, post-war brick ranches across the south and east sides, 1970s and 1980s split-levels in the suburbs, and brand-new construction around Clemmons, Lewisville and Kernersville. Each era came with its own pipe materials, and each has its own typical problems.

Very soft water, and what that means for your pipes

Most homes in the city and much of Forsyth County get their water from Winston-Salem/Forsyth County Utilities, which treats water from the Yadkin River and Salem Lake at the Neilson, Swann and Thomas plants. The utility's 2025 water quality report lists average hardness of about 17.5 parts per million, which is very soft water (Winston-Salem/Forsyth County Utilities, 2025 Water Quality Report). That is good news for water heaters and fixtures, because you do not get the heavy scale that plagues hard-water cities. Soft, low-mineral water can be more aggressive toward metal pipes, which is why the utility adds orthophosphate as a corrosion-control treatment. In older homes, pinhole leaks in copper and rust inside galvanized steel are still worth watching for.

Older service lines and the lead and galvanized inventory

Under a federal requirement, WSFC Utilities has built an inventory of the private service lines that run from the meter to each house, and it has mailed letters to owners whose line material is listed as lead, galvanized requiring replacement, or unknown. If you received one of those letters, the utility asks you to self-report the material through WSFC Utilities service line inventory (cityofws.org/pipes) and says owners with a verified lead or galvanized line should wait for its replacement plan before acting. We can talk through what you are seeing at the house, but the utility's guidance comes first.

Red clay, big trees and sewer laterals

Much of the Piedmont sits on dense red clay, and Winston-Salem has a lot of mature oaks, maples and willow oaks. Roots find their way into older clay and cast-iron sewer laterals, and clay soil that shrinks in dry summers and swells in wet winters can shift joints. A main drain that clogs again a few weeks after it was cleared is often a root or a sag in the lateral, not a simple clog.

Crawlspaces and cold snaps

Winters here are usually mild, with average January lows in the upper 20s, but arctic outbreaks do reach the Triad, and the area's record low is well below zero. Many Winston-Salem houses sit over vented crawlspaces, and supply lines that run along an outside wall or near an open foundation vent are the first to freeze. Knowing where your main shut-off is, and insulating exposed pipes before the first hard freeze, prevents most of the damage we hear about.

Who handles what when a sewer backs up

If your home is on public sewer and wastewater comes up through a floor drain, tub or basement fixture, Winston-Salem/Forsyth County Utilities asks residents to call City Link at 311 or 336-727-8000 first. Utility crews check and clear any blockage in the part of your service line that sits in the public right-of-way, and they will look at the courtesy cleanout at the edge of the right-of-way if there is one (WSFC Utilities, Sewer Backup Policy & Responsibilities). If the line is clear on the city side, or there is no cleanout, the blockage is on the private side and the homeowner hires a plumber. The utility's policy asks that the plumber clear the line all the way to the main and camera-inspect it, so keep any video and invoices. Calling the utility before cleanup also matters if you might qualify for its Good Neighbor Policy reimbursement (WSFC Utilities Good Neighbor Policy).

What to do while you wait

• Water running where it should not? Close the main shut-off. In crawlspace homes it is usually where the supply line enters the foundation, often near the front of the house; some homes also have a valve at the meter box by the street.
• Water heater leaking? Close the cold-water valve on top of the tank. For an electric heater, switch off its breaker; for gas, turn the control knob to "pilot" or "off."
• Toilet overflowing? Turn the small oval valve behind the toilet clockwise and lift the flapper inside the tank.
• Smell gas? Leave the house and call the gas utility or 911 from outside. Do not switch lights or appliances on or off.

Questions worth asking before any plumbing work

• What exactly is wrong, and how was that confirmed (camera inspection, pressure test, moisture reading)?
• Is the quote a flat price for the job or time and materials, and what could change it?
• Does the job need a permit and inspection? Water heater replacements and new or rerouted piping usually do in North Carolina.
• What materials will be used, and what manufacturer warranty comes with new equipment?
• Who patches drywall or restores the yard if lines have to be opened up?

Not sure what you need? The guides cover shut-off valves, who owns the sewer line, and tank versus tankless water heaters.
