If water is spraying or sewage is backing up in a Bethesda home, shut the main valve to limit the damage, and for any gas smell, get everyone outside first. Then call the number on this page to be connected with a local plumber in Bethesda.

When you call
The number on this page connects you with an independent plumber who handles urgent jobs in Bethesda. Have a short description ready: what broke, whether the main is shut, and whether water has reached outlets or the electrical panel. Give the address and a cross street such as Old Georgetown Road, River Road or Wisconsin Avenue, and mention parking or building access if you live in a Woodmont Triangle condo. Ask how after-hours pricing works before a visit is booked. Arrival times are not promised; they depend on the time of day and each plumber's workload.
Cost drivers
- Timing. After-hours, weekend and holiday calls typically cost more.
- Age of the plumbing. Older galvanized or cast iron pipe may need a longer section replaced rather than a patch, because the pipe next to the break is often in similar shape.
- Getting to it. Plaster walls, finished basements and tight crawlspaces add labor.
- Required permits. WSSC Water Permit Services issues plumbing and gas permits in Montgomery County, and the County's Department of Permitting Services handles building permits. Gas appliance replacements and water or sewer service line repairs must be done by someone holding a WSSC license.
Local conditions in Bethesda
Bethesda's housing skews older. In ZIP 20817, about 64 percent of homes were built before 1980, and the biggest single group dates from the 1950s. Houses from that era in Edgemoor, Battery Park and along the River Road corridor can still carry original supply pipe, cast iron stacks and basement floor drains that back up when a lateral clogs with roots.
WSSC Water provides water and sewer, so street-side main breaks and sewer overflows go to its emergency line at 301-206-4002. Washington Gas serves the area and has facilities along River Road. For a gas odor, leave the building, then call 911 and 844-WASHGAS (844-927-4427), option 1, once you are outside.
Quick checklist
- Close the main and open a basement faucet to relieve pressure.
- Turn off the water heater's power or gas if it is the source.
- Keep everyone off drains that are backing up.
- Take photos for your insurance company before cleanup.
- Unlock the basement door and move stored items away from the water heater and main valve.
