Cost to Replace a Sewer Line
Replacing a sewer line means excavating to expose the damaged pipe, removing old sections, installing new PVC piping and fittings, then backfilling and compacting the trench. It is a hard project because the damage must be located accurately and excavation creates utility-strike and trench-collapse risks.
Common reasons homeowners do this job
- A sewer line that is worn or damaged
- Damage that needs a camera inspection to identify its location and extent
- Old pipe sections that need to be removed and replaced
- A sewer-line upgrade requiring new PVC piping and fittings
DIY or call a pro?
A licensed professional should replace a sewer line. Excavation can strike underground gas, electric, or water lines, and a manually or mechanically dug trench can collapse. A professional can locate the damage, coordinate utility marking before digging, install the piping, and arrange the final review. Check with your local building department whether this work needs a permit.
Frequently asked questions
- Can I replace my own sewer line?
- Hire a licensed professional. This is a hard project that requires one because it involves excavation, municipal plumbing systems, underground utilities, and the risk of trench collapse.
- What makes sewer line replacement more expensive?
- The price can rise with the job's size, labor time, piping and fitting materials, haul-away of old material, and a minimum or trip charge for a small job.
- What should be checked before a sewer line is replaced?
- Start with a professional camera inspection to identify the location and extent of the damage. Underground utility lines should also be marked before any digging begins.
- Why is trench work a major concern during sewer line replacement?
- Digging can strike underground gas, electric, or water lines. Whether digging is done manually or mechanically, the trench can also collapse, which is why excavation needs professional handling.
