Most sewer line repairs start with a camera inspection. The fix itself usually costs $150 to $3,800, depending on the method. If the line needs full replacement, expect $50 to $250 per linear foot, according to HomeGuide’s 2026 sewer line cost data. Our sewer line replacement cost guide breaks down replacement pricing by method.

Sewer trouble is common across Fairfield County, CT, and Westchester County, NY. Many homes here were built decades ago, and their clay or cast iron laterals run under mature trees. We get these calls from Danbury, Bethel, Brookfield, New Milford, Newtown, Ridgefield, Wilton, and towns throughout Westchester.

A failing sewer line rarely fixes itself, and every flush can push wastewater into your yard or basement. All State Plumbing Pros offers sewer line repair and camera inspection as part of its drain and sewer services. You get upfront pricing before any work begins.

How do you know it’s your main sewer line?

Multiple slow drains at the same time usually mean the problem is in the main sewer line. One slow sink points to a local clog in that fixture’s branch. Other warning signs include gurgling toilets, foul odors indoors, frequent backups, and soggy patches in the yard. If the sewer backs up into a floor drain after a flush, the blockage sits further down the main line. A broken sewer line won’t raise your water bills the way a supply leak can, since the meter measures only water coming into the house. See our guide to main sewer line clog warning signs.

Why sewer lines fail in older Fairfield County and Westchester homes

Sewer lines fail mostly from age, tree root intrusion, pipe corrosion, and soil movement. HomeGuide puts the lifespan of Orangeburg and clay sewer pipe at 30 to 60 years. PVC, cast iron, and copper lines last 50 to 100 years. In old cast iron pipes, corrosion slowly thins the pipe walls from the inside. Tree roots work into loose pipe joints and grow until they block the line. We see a lot of root intrusion on older lots around Danbury and Ridgefield. Shifting soil and ground movement can also crack or sag a line.

How a camera inspection pinpoints the problem

A sewer camera inspection shows the exact location of the damage and what caused it, without digging. A plumber feeds waterproof camera equipment through a cleanout or another access point. The live feed shows cracks, roots, offset joints, sags, and collapses in the underground pipes. We run a camera through every line before recommending a repair method, since a clog and a collapse can look the same from inside the house. A proactive inspection is also smart before buying an older home. Our sewer line inspection guide explains what the footage shows.

Sewer line repair vs. replacement

Sewer repair fixes one damaged section of pipe, while sewer replacement swaps out the whole line from the house to the main. The footage usually shows which is the best solution. A single cracked joint or one spot where tree roots got in can be repaired. A line that has collapsed or cracked along much of its length is close to full failure. HomeGuide notes that partial repairs cost less because they often cover only 1 to 15 feet of pipe.

Trenchless and traditional repair methods

Plumbers repair sewer lines with spot repair, cured-in-place pipe (CIPP) lining, pipe bursting, or dig and replace. Spot repair uses targeted excavation: one small hole to replace just the damaged piece. CIPP pipe relining cures a resin-soaked liner inside the old sewer pipe, so the line must still hold its shape. Pipe bursting pulls a new pipe through the old one and breaks it apart. Traditional excavation opens a full trench, which still makes sense for a collapsed pipe or a bad slope.

Homeowners often ask us whether trenchless sewer repair is always cheaper. Per foot, the price ranges overlap with digging. The real advantage is minimal disruption to your lawn, driveway, and walkways.

What is the average cost to repair a sewer line in 2026?

Sewer line repairs cost $150 to $3,800 on average, depending on the method, according to HomeGuide. The depth of the pipe and what sits on top of it also drive the price. Add-ons like a new cleanout or a permit can raise the total. Repairs often need a local permit, so check with your town. An on-site inspection is the only way to get a firm price.

Who is responsible for the sewer line, you or the town?

Homeowners are generally responsible for the sewer lateral from the house to the main, per HomeGuide. The town or city is responsible for the main itself. Rules for the connection point and any section under the street vary by town, so call your public works or sewer department before you schedule work. The camera footage also shows whether the problem sits on your side or the town’s.

How long does sewer line repair take?

Sewer line repair or replacement usually takes 1 to 5 days, according to HomeGuide, and trenchless jobs finish faster. A spot repair or a short lining job is often the quickest. A full dig and replace takes longer, especially when crews cut through a driveway. Permit approval can add time before work starts, so ask about it when you get your estimate.

How to prevent sewer line problems

Regular sewer line cleaning and a few household habits prevent most clogs and backups. Most homes do well with professional sewer cleaning every 18 to 24 months. Older clay or cast iron lines near mature trees often need it once a year. For heavy buildup, hydro jetting uses high-pressure water to scour grease, scale, and root fragments off the pipe walls. Inside the house, avoid flushing wipes, even ones labeled flushable, along with paper towels and grease. Adding a cleanout also makes future drain cleaning easier.

What to do right now if you suspect a sewer line problem

Stop sending water down the drains first, then get the line inspected before the backup gets worse. If sewage is already coming up through a floor drain, ask for an emergency response when you call. These steps keep the damage small while you wait:

1. Stop running water: hold off on flushing, laundry, showers, and the dishwasher.
2. Skip chemical drain cleaners, since they rarely clear a main line and can harm older drain pipes.
3. Keep kids and pets away from any sewage, and avoid touching it without gloves.
4. Note which fixtures are slow or backing up, since this helps the diagnosis.
5. Call a professional plumber to run a camera and find the cause.

How to choose a sewer line repair company near you

Choose a fully licensed, insured plumber who runs a camera first and shows you the footage before quoting. In Connecticut, you can check a plumber’s license on the state’s eLicense system. Connecticut’s consumer protection agency walks you through verifying a plumber’s license online. In Westchester, ask for the company’s county license. Online reviews and neighbor referrals help you spot patterns among sewer repair companies. In our experience, the best sign of a good contractor is a written quote that names the scope, method, pipe length, and who handles permits and restoration.

Conclusion

Sewer line problems usually show up as slow drains or gurgling in several fixtures at once. Camera footage tells you whether you need a small repair or a full replacement. Most repairs run $150 to $3,800, while sewer replacement costs $50 to $250 per linear foot. Routine sewer line cleaning or hydro jetting helps keep the next clog away.
