Most Missouri sewer problems come from tree roots, shifting clay soil and aging clay or cast iron pipe. We start with a camera inspection to locate the exact problem and depth, then recommend the least invasive fix: spot repair, pipe lining or replacement.
Our crews handle permits and utility locates, and we restore your yard when excavation is required.
Homes in St. Mary range from older houses with original galvanized and cast iron plumbing to new construction with PEX — and each needs a different approach to sewer line repair. Our St. Mary plumbers know the local housing stock, soil conditions and water quality, so you get a lasting fix instead of a temporary patch.
