Sewer line replacement in Lanham installs new pipe from your home to the WSSC Water sewer main. With a median home built in 1969, many Lanham lines are original and have reached the age where repeat clogs, roots and cracks point to replacing the whole run. Call the number on this page to be connected with a local plumber in Lanham.

Lanham's local conditions
Lanham is an unincorporated, fully built-out suburb along the Capital Beltway next to the New Carrollton Metro and Amtrak station. The Lanham mailing address covers more ground than the census community, including Seabrook. WSSC Water provides drinking water and wastewater service, and its emergency line, 301-206-4002, is for trouble in the public system. A backup that affects only your house points to the private line, which is the owner's responsibility.
Census estimates put Lanham's median home at 1969. That puts much of the housing in the era when laterals were often clay or cast iron. Clay joints let roots in, and cast iron corrodes from the inside until it cracks or flattens. After 50-plus years, a camera often finds several weak spots instead of one, and that is when replacement starts to make sense. WSSC requires water and sewer service line replacements to be done by a plumber holding a WSSC license, under a WSSC permit, and Prince George's County DPIE handles building permits.
| Repair a section | Replace the line | |
|---|---|---|
| Best for | One crack or root point | Damage along the run, sags, collapse |
| Digging | One small excavation | A trench, or pits at each end if trenchless |
| What remains | The rest of the old pipe | New pipe end to end |
| Future clogs | Likely elsewhere on old pipe | Much less likely |
Signs of a failing line
- Backups that return weeks after a clearing
- Water coming up in a basement floor drain
- Gurgling from toilets when other fixtures run
- Sewer smell around the cleanout or yard
Timing and seasons
Heavy summer storms tend to reveal weak sewer lines, because groundwater gets into cracks and a sag fills faster. A replacement found on a routine inspection can be scheduled for dry weather. In winter, frozen ground slows digging, but trenchless work and urgent repairs still go ahead. If sewage is already in the basement, do not wait.
When you call, you will be connected with an independent local plumber who works in Lanham and Seabrook. Expect a camera inspection and a locate before a firm price, followed by a clear explanation of the method, the WSSC permit, and when the inspection happens before the line is covered.
