What counts as a plumbing installation
The term covers more than hanging a faucet. It includes running new hot and cold lines, adding drain and vent pipe for a bath or laundry, setting a fixture, connecting an appliance and installing shutoff valves and pressure regulators. Each one has to drain by gravity, vent so traps do not siphon and stay accessible for later service.
Fixtures and appliances that need their own pages have them. See water heater installation for tank and tankless units, and toilet installation for replacing a toilet. This page covers the plumbing that sits behind and around them.
New construction: from rough-in to final
- Plan the layoutThe plumber works from your plans to place stacks, supply trunks and fixture locations, and flags conflicts with framing or ductwork early.
- Rough-inDrain, waste, vent and supply lines go in before the walls are closed. Pressure and drainage tests are run so leaks show while everything is open.
- InspectionThe rough-in is inspected by the local inspector before drywall. Ask the Winston-Salem/Forsyth County Inspections Division at 336-727-2624 how scheduling works for your project.
- Trim-outFixtures, faucets, toilets and appliance connections are set and tested after the walls are finished.
Fixture rough-ins: decisions to make before walls close
Changing a drain after drywall is expensive. Settle these points with your builder or designer while the framing is open.
- Exact fixture models, since the rough-in dimensions depend on the model you pick.
- Valve and shutoff placement so you can reach them without removing finished surfaces.
- Tub and shower valve type and height, including whether you want a handheld sprayer.
- Vanity height and whether a double sink needs a second drain.
- Laundry box location, drain size and a drain pan if it is above living space.
- Hose bib locations and whether an outdoor shutoff is wanted inside.
- Access panels behind tub and shower valves.
Water softener and filtration: do you actually need one?
Many people assume every home needs a softener. Winston-Salem/Forsyth County Utilities reports soft water in its 2025 Water Quality Report: hardness from 9.0 to 28.0 ppm with an average of 17.5, which is roughly one grain per gallon. At that level a softener adds salt, maintenance and a drain line while solving little.
Check your bill to see who supplies your water, because some properties use private wells, and well water differs from home to home. We do not guess a well's hardness. A lab test or a hardness test strip on your own tap is the only way to know.
Filtration is a separate question. Chlorine taste is common in treated water and a carbon filter at the kitchen sink handles it. Whole-house filters make sense for sediment, iron or other specific problems a test has shown. Tell the dispatcher what you taste or see, and we advise you before you buy equipment.
Ready to plan fixtures, a new line or a bathroom add, call (336) 453-0472 and tell us what you are building.
Gas lines: safety first, then the right licence
Once the utility has made the area safe, a licensed professional can repair or extend gas piping. Fuel piping needs the right licence under N.C. G.S. 87-21, so verify any installer on the North Carolina licensing board lookup before hiring. We do not run gas lines unless the work falls within our licence, and we tell you plainly if it does not.
Gas appliance connections, new range lines and pipe sizing are all done to code and tested before use. Ask the Inspections Division whether a permit is needed.
Get everyone out, do not flip switches or use a phone inside, and call the gas utility or 911 from outside. Do not wait on a plumber, and do not go back in until you are cleared.

Permits, licences and who is allowed to do the work
North Carolina requires a license to engage in the business of plumbing contracting under N.C. G.S. 87-21. Class I covers all structures, and Class II covers single-family detached homes. Look up any plumber at public.nclicensing.org before signing.
Plumbing permits and inspections for Clemmons go through the Winston-Salem/Forsyth County Inspections Division. Ask the Inspections Division whether your job needs a permit. A licensed plumber handles the paperwork and scheduling for work that needs it.
What drives the cost of a plumbing installation
Plumbing is priced by scope, and a clear price comes before work starts. The line is open 24/7 to schedule.
- Fixture countmore fixtures mean more supply and drain runs.
- Distancea bathroom far from existing lines needs more pipe and trenching.
- Accessopen framing is cheaper than cutting into finished walls or a slab.
- Materialscopper, PEX and fixture quality change the number.
- Inspectionspermit and inspection coordination add time.
Insurance and getting your real number
Insurance rarely covers planned installations. It may cover water damage if a new line fails suddenly, but not the new line itself, so check your policy. Call (336) 453-0472 with plans or a description and we will give you your real number. Existing leaks or aging lines in the same wall are worth sorting out first, and our repiping and leak detection pages explain how.
Frequently asked questions
Can you do plumbing for new construction in Clemmons?
Yes. The plumber works from your plans, runs rough-in before walls close and sets fixtures after finishing. Rough-in inspections are scheduled through the county Inspections Division at 336-727-2624.
Do I need a water softener in Clemmons?
Possibly not. The Winston-Salem/Forsyth County Utilities 2025 report lists soft water, an average of 17.5 ppm. Check your bill to see who supplies your water, and test your tap. Well homes differ.
I smell gas. Should I call a plumber?
Leave the building first, then call the gas utility or 911 from outside. Do not turn on lights or use a phone inside. A licensed professional repairs gas piping after the utility says it is safe.
How do I check that a plumber is licensed?
Use the public license search at public.nclicensing.org. North Carolina requires a license to engage in plumbing contracting, and Class I and Class II cover different property types.
Does every installation need a permit?
Ask the Winston-Salem/Forsyth County Inspections Division at 336-727-2624 whether your job needs a permit. We do not guess which jobs are exempt.
Can you add a bathroom in my existing house?
Usually yes. The key questions are where the drain and vent can run and whether the supply lines have capacity. Call (336) 453-0472 and describe the space.
