Burst and Frozen Pipe Repair in Washington, DC
In Washington's rowhouses, pipes freeze in rear additions, unheated basements and along the exposed side wall of an end unit. A burst pipe can damage the house next door through the shared wall. Shut off the main valve, usually at the front basement wall where the service enters.

What is different about burst and frozen pipe repair in Washington?
The rear of the house is the usual location. Many rowhouses have a kitchen or bathroom in a back addition, sometimes a former sleeping porch that was enclosed, built over a crawl space or open air with thin insulation. Supply lines there freeze while the main house stays warm.
DC winters swing between mild spells and sharp cold snaps, so pipes that survived one winter can freeze the next. Outdoor hose bibs split when a hose is left attached. In a house with a basement rental unit, make sure the tenant knows where the shutoff is and can reach it.

Burst and Frozen Pipe Repair questions from Washington
Where is the water shutoff in a DC rowhouse?
Usually on the front basement wall, where the service line enters and the meter sits, though some meters are in a box in the front yard. Find it and test it before winter.
How do I protect pipes in an enclosed porch or addition?
Keep the space heated, open cabinet doors under the sink in cold weather, let the faucet drip on the coldest nights and seal drafts where pipes come through the floor. Rerouting the pipe is the lasting fix.
