Less digging, if your pipe qualifies.

Cured-in-place pipe lining creates a new interior within a suitable existing pipe. Preparation can include cleaning, measurement and reinstatement of approved connections. Ask how the contractor confirms diameter, continuity and cure quality, and request final camera footage. A liner generally follows the existing route and does not necessarily correct a low spot.

Pipe bursting replaces the existing pipe along a feasible route, using access locations and utility clearance. It is not automatically permitted or practical at every property. Ask about nearby utilities, connection work, access pits and city acceptance before comparing its price with lining. Neither method means zero excavation or zero restoration.

On an established Metro Detroit lot, protecting a driveway, walkway or landscaping can make a suitable trenchless method attractive. The comparison should still include pit placement, cleanout work, cleaning, municipal approvals and final surface repairs. A cheaper per-foot offer can exclude expensive preparation.

If the camera shows collapse, severe displacement or a substantial grade problem, ask exactly how the method will address it. A limited excavation combined with lining may be a different scope from a whole-line liner. Obtain a written description of repaired length, exclusions, inspection and warranty rather than accepting the word trenchless as a complete specification.
