Sewer Line Repair & Replacement in Washington, DC
Looking for a sewer line repair & replacement in Washington? Here's the short version of what we do, what it costs, and how soon we can be there. Three things you can count on: we show up when we say we will, we quote before we work, and we don't pad the bill.
How Washington jobs differ
Newer Washington construction tends to be on slab foundations with PEX. Easier access in some ways, more code-current in others.
Most of our Washington sewer line repair & replacement jobs come from older neighborhoods, where the housing stock just has more failure points.
Sample job
Recent Washington job: basement floor drain backing up after laundry in a 1940s home. We spot-repaired the bellied section after diagnosing a belly in the lateral was holding water. Cost ran $425 — pretty middle-of-the-road for that fix.
What we cover
Sewer lateral problems hit older homes hardest. Anything pre-1970 in most U.S. cities still has either clay-tile or Orangeburg laterals from the original build. Both fail. Tile cracks at the joints; Orangeburg collapses under load.
Diagnosis order: cable first, then camera. Cable clears most active blockages. The camera shows you what's actually happening down there — joint offsets, root invasion, bellies, broken sections.
Repair options depend on the lateral. Spot repair on a single broken section: $3,200–$6,500. Trenchless pipe burst on the full lateral (replaces clay or cast iron with new HDPE): $6,500–$14,000. Open-trench replacement: rare anymore, only when trenchless isn't feasible.
Permit is almost always required. Municipal sewer authorities want to inspect lateral work before backfill. We pull the permit and coordinate the inspection.
