Plumbers in Upper Marlboro, MD

A small town with a big address

The Town of Upper Marlboro, incorporated in 1870, has been the Prince George's County seat since 1721 and had just 652 residents in 2020. It is about 15 miles from downtown Washington in a straight line, along the Western Branch of the Patuxent River, and is dominated by county government, including the Prince George's County Courthouse. The Upper Marlboro postal area is a different thing: roughly 77 square miles of unincorporated land with nearly 20,000 residents, mixing horse-farm countryside with growing developments such as Westphalia and Brock Hall. US 301, MD 4 (Pennsylvania Avenue) and MD 725 (Main Street) tie it together, and The Show Place Arena is a regional draw. Most homes with this address are outside the town.

Water and sewer vary by address

WSSC Water operates mains serving customers in the Upper Marlboro area. In the outlying rural parts of the postal area, service varies by address: some properties may have a private well, and some may not be on municipal sewer. Your bills are the quickest way to know. For homes on WSSC water, WSSC adds an orthophosphate corrosion inhibitor, says it has removed all known lead pipes from its distribution system, and publishes a map of service line materials, including the private-property side, at wsscwater.com/LCR-map. WSSC's emergency line for water and sewer problems is 301-206-4002.

Housing

The median home in the Upper Marlboro area was built around 1982. That covers older farmhouses and town buildings alongside newer subdivisions, so repairs range from tired galvanized pipe to water heaters, sump pumps and fittings in houses only a few years old.

Permits

All plumbing permits in Prince George's County come from WSSC Water Permit Services (301-206-4003), and the Town of Upper Marlboro points residents to the county's DPIE for building permits. Replacing existing fixtures generally needs no permit, but water heaters and testable backflow devices do. Water and sewer service line repairs and gas water heater replacements must be done by a plumber or gasfitter holding a WSSC license.

Gas and propane

Washington Gas and BGE both serve parts of Prince George's County, and some rural properties may have no gas main and use propane or electricity instead. Check your bill to see who supplies yours. If you smell gas, leave the house first. Once outside, call 911 and your gas utility, or 911 and your propane supplier if your home runs on propane.

Compared with the District

Every Washington address is on DC Water and public sewer. Around Upper Marlboro, you may be on WSSC lines or on a well, and on utility gas or propane. When you call, tell us what you have and what is wrong, and you will be connected with an independent plumber who sets the price and timing with you.
