Washington D.C. and Northern Virginia plumbing is its own discipline. Our homes are old β most rowhouses still have original lead service lines and galvanized supply runs from the 1920s; tree roots love D.C.'s clay sewer mains; and historic districts pile HPRB approval requirements on top of standard permitting. We are an Arlington-based team serving Washington D.C., Arlington, Alexandria and Fairfax County.
Why i4improvements for plumbing in the DMV
Plumbing in D.C. and Northern Virginia is shaped by the age of the housing stock. Original lead service lines still run under most pre-1980 rowhouses; tree roots attack clay sewer mains; hard water shortens water heater lifespans. We have worked in Capitol Hill mechanical closets, Arlington utility rooms and Fairfax new builds, and we know the local layer (Lead Free DC, historic-district venting, BBL rental requirements) as well as the work itself.
