Your home’s drain and sewer line carries wastewater from every fixture to the outdoor lateral. Over time, age, root intrusion, soil movement, corrosion, and low spots can damage the pipe, leading to frequent clogs and slow drains.
Temporary fixes might offer short-term relief, but they don’t address the underlying structural issues. A professional evaluation will pinpoint the exact cause of the damage, how extensive it is, and which replacement method is best for your site and budget.
Our approach starts with a camera inspection and electronic locating. With a clear map of the pipe’s condition and depth, our licensed plumbers will recommend the most appropriate method: open trench replacement, trenchless pipe bursting, or cured-in-place pipe lining, based on your site conditions.

Some surface impact is likely. Trenchless methods reduce digging, but access pits are still required. If the line crosses driveways or patios, we’ll discuss cut-and-patch plans before starting, and restore any disturbed areas after the work is completed.

Factors such as length, depth, soil type, number of bends, surface restoration, and access all impact pricing. A camera inspection and locate allow for an accurate estimate and firm pricing.
Yes, we coordinate permits with the city or county and arrange for utility marking through 811 before beginning excavation or access pit work.
Trenchless methods work well when the existing pipe path is mostly straight and the host pipe can handle bursting or lining. Severe collapses, major offsets, or tight bends may require open trench in part or in full.
