We diagnose sewer problems with a camera first, then repair or replace the line — including the old clay and Orangeburg laterals common in this area.
Recurring backups, gurgling drains, or sewage odor usually trace to a single failure point. We run a camera inspection to locate it precisely, so you are not paying to dig up a line that only needs a spot repair.
Our team installs and repairs residential and commercial water systems using the latest tools and code-compliant techniques.

Many Dunkirk homes, especially in the harbor district and neighborhoods toward Fredonia, were built when clay and Orangeburg (bituminized fiber) sewer pipe was standard. These materials crack, collapse, and admit tree roots as they age. Knowing the build era of a neighborhood helps us anticipate what is underground before we open it up.
Where the existing line allows, trenchless repair restores the pipe with less excavation. If you are buying a home near Lake Erie and the working harbor, a sewer-scope inspection before closing can reveal a failing lateral that would otherwise become your problem.
