A plumbing inspection is a walk-through of the supply piping, drains, fixtures, water heater and shutoffs, often with a camera run of the sewer line. In Durham it is especially useful on homes built before 1988, which the City says may have a lead service line. Call the number on this page to be connected with a local plumber in Durham who can inspect the house.

When an inspection pays off
- Before buying, to catch problems a general home inspector may only flag.
- Before a remodel, so new finishes are not built over old pipe.
- After a leak, a sewage backup or a jump in your water bill.
- When an older house has never had its plumbing looked at closely.
Why the age of a Durham home matters
Durham's housing runs from historic pre-war neighborhoods to heavy post-2000 growth. Census estimates put the median year built at 1995, with roughly 30 percent of homes built before 1980. Older houses are more likely to have galvanized steel supply lines, cast iron drains, or clay sewer pipe that roots can work into.
The City's 2024 water quality report says homes built before 1988 may have a lead service line and suggests a simple check: a lead pipe is dull gray, scratches to a shiny silver and will not hold a magnet. The City is inventorying service lines and offers free lead testing.
What a plumber checks
| Area | What they look for |
|---|---|
| Service line and main shutoff | Pipe material, condition, whether the valve works |
| Supply piping | Corrosion, mixed metals, leaks, pressure |
| Drains and vents | Slow drains, cracks, improper slopes or traps |
| Sewer lateral | Roots, sags and breaks, usually seen by camera |
| Water heater | Age, relief valve, venting, signs of leaking |
| Fixtures | Running toilets, dripping valves, worn supply hoses |
After the inspection
You should get a clear list of what is fine, what to watch and what needs work. Larger fixes such as replacing a private water or sewer service line require a plumbing permit from Durham City-County Building & Safety, so ask whether a recommended repair would need one.
What affects the price
Cost depends on home size, the number of bathrooms and fixtures, how accessible the crawl space or basement is, and whether a sewer camera inspection is added.
Getting ready for the visit
Clear a path to the water heater, the main shutoff and any crawl space hatch. Note anything you have already noticed, such as a toilet that runs, a drain that gurgles or a stain on a ceiling, so the plumber can look at those spots first. If you are buying, ask the seller for any records of past repairs, repiping or sewer work, and plan to be there so you can see problems in person rather than only reading about them later.
