FAQs
Plain answers about sewer lines and trenchless repair.
These are the questions homeowners ask once the drains start backing up.
Signs and causes
What are the signs of a broken sewer line?
Several drains slowing at once, gurgling toilets, backups in the lowest drain, sewer smell outdoors, a soggy or extra-green strip in the yard, and clogs that return after snaking.
What causes a belly in a sewer line?
Soil settling under the pipe, often poorly compacted backfill or shifting clay, lets a section sag. Waste collects in the low spot and causes repeat clogs.
How serious are roots in a sewer line?
Serious enough to fix properly. Roots enter through cracked joints, grow into a mat that blocks the line and widen the cracks over time. Cutting them only buys months.
Should Orangeburg pipe be replaced?
Yes. Orangeburg is fiber pipe used roughly from the 1940s to the early 1970s, and it flattens and blisters with age. It is usually replaced by pipe bursting rather than lined.
Lining, bursting and the job itself
How long does trenchless sewer repair take?
Most residential lines are inspected and lined or burst in one day, sometimes two. Water is off for a few hours while a liner cures.
What are the disadvantages of trenchless pipe lining?
A liner follows the old pipe, so it cannot fix a collapsed section or a belly that holds water, and it narrows the bore slightly. Those cases call for bursting or a short dig.
Can a sewer line be replaced without digging?
Almost. Trenchless methods use one or two small access points instead of a trench, and lining can sometimes run entirely from an existing cleanout.
What is the difference between pipe lining and pipe bursting?
Lining forms a new pipe inside the old one with a resin-soaked liner. Bursting breaks the old pipe outward and pulls a new HDPE pipe into its place, between two small pits.
Do I need a permit to fix my sewer line?
Almost always. Most cities require a plumbing permit for lateral work, and a right-of-way permit for anything in the sidewalk or street. The crew pulls them where needed.
Cost, life and responsibility
Is trenchless sewer repair worth it?
Usually, when the line runs under a driveway, landscaping or a slab. Pipe work per foot costs about the same as digging, but there is far less to restore afterwards. The camera shows whether your pipe qualifies.
How long does trenchless pipe lining last?
Cured-in-place liners are engineered for about 50 years. HDPE pipe pulled in by bursting is rated for 50 to 100 years.
Who is responsible for the sewer line from the house to the street?
In most cities the homeowner owns the lateral from the house to the city main or the property line. Rules vary by city, so the boundary is confirmed for your address.
How much does trenchless sewer repair cost per foot?
An estimated $80 to $250 per foot for lining or bursting, so most residential lines run an estimated $4,000 to $15,000. Spot repairs are estimated at $1,500 to $4,000.
Is it worth repairing a sewer line instead of replacing it?
When the damage is one short section, a spot liner is the sensible spend. When cracks, roots and corrosion run the whole length, lining or bursting the full line is.
