What affects the cost
- What is wrong. Roots or a clog may only need cleaning. A broken or collapsed pipe needs a section or the whole line replaced.
- Length and depth. Longer and deeper lines cost more to dig or line.
- Trenchless or digging. Trenchless methods can save your yard, driveway or landscaping. Digging can cost less when the line is shallow and under open lawn.
- What is on top. HomeGuide notes lines under basements, driveways or trees cost more to replace than lines under soil or sod.
- Permit and city connection. Work on the line to the street usually needs a permit, and connecting to the city main may involve city fees.
Questions to ask a shop
- Can I see the camera footage, and where exactly is the problem?
- Is this a repair, a section replacement, or a full replacement? Why?
- Trenchless or digging, and what would each cost here?
- Does the price include restoring the lawn, driveway or sidewalk?
- Will you get the permit and arrange the inspection?
- Who is responsible for the part of the line near the street, me or the city?
- What warranty do you give on the work?
