Sewer Line Repair & Replacement

Your main sewer line is the underground pipe that carries wastewater from your home out to the city sewer connection or your septic tank. When it's damaged, the signs can be dramatic — sewage backing up into the house, wet or lush spots in the yard, or multiple drains slowing down at once. In older Charleston-area homes with clay or cast iron sewer lines, damage is common. Sandy Lowcountry soil, aging pipe materials, and tree roots all take their toll over time.

At Yeehaw Plumbing, we handle sewer line repair and full replacement across Summerville, Charleston, and the surrounding Lowcountry. Every job starts with a camera inspection so you see what we see — cracks, roots, collapses, or displaced joints — and we walk you through the options before any work starts.

Call (843) 509-6943 and we'll get someone out to take a look.

Common Causes of Sewer Line Damage

‍

Sewer lines fail for a handful of predictable reasons in Lowcountry homes:

‍

• Tree root intrusion pushing into pipe joints (very common with older clay lines)
• Corrosion in aging cast iron sewer pipes
• Cracked or collapsed clay pipe sections
• Ground movement from sandy, shifting Lowcountry soil
• Damage from settlement, nearby construction, or heavy equipment
• Old joints or fittings failing after decades in the ground
• Bellied or sagging sections where the pipe has settled and traps waste

‍

If your home is more than 40 years old and the sewer line has never been replaced or evaluated, it's worth a camera inspection before an emergency forces the issue.

‍

Signs You May Have a Sewer Line Problem

‍

Sewer line problems build up over weeks or months before they fully fail. Warning signs to watch for:

• Multiple drains slow or backing up at the same time
• Sewage smell inside the home or outside near the yard
• Gurgling sounds from drains or toilets
• Sewage backing up out of the lowest drain in the house (floor drains, ground-level tubs)
• A wet, soggy, or unusually green patch of grass over the sewer line
• Sinkhole or depression forming in the yard along the pipe run
• Recurring clogs at the main line even after cleaning
• Slow flushing across the whole house

‍

If you're seeing more than one of these, don't wait — sewer problems get worse, not better, on their own.

‍

Our Sewer Line Repair Process

‍

Every sewer line call starts with figuring out what's actually wrong and where. We don't dig blind.

‍

Our process:

‍

• Camera inspection down the sewer line to locate the damage and see its extent
• Explain exactly what we found — roots, cracks, collapses, bellies
• Discuss options: spot repair, section replacement, or full line replacement
• Get the necessary utility locates so we don't hit gas, power, or other lines during excavation
• Dig only where we have to for the specific repair, minimizing yard disruption
• Cut out the damaged section and install new pipe (usually PVC for repairs and replacements)
• Backfill and restore the ground as best we can — we'll flag if you'll need a landscaper to finish
• Follow up with a final camera check to confirm the repair holds

If the whole line is compromised and repairs will just kick the can down the road, we'll walk you through what a full replacement costs and what it involves.

Sewer Line Repair vs. Drain Repair — What's the Difference?

‍

Drain repair covers the pipes inside your home and the short runs under the foundation before they connect to the main sewer line. Kitchen drains, bathroom drains, laundry lines, floor drains, and the branch lines that tie them together.

Sewer line repair covers the main line running from your house out to the city sewer connection or your septic tank. It's underground, exterior, and involves different tools, different pipe materials, and different access methods.

If the problem is affecting one or two fixtures inside the house, that's usually drain repair. If multiple drains are backing up at once, or if you're seeing yard issues over the pipe run, it's more likely a sewer line problem.

‍

Sewer Line Repair vs. Water Main Repair — Different Systems

‍

Sewer lines and water mains run underground in your yard, but they carry water in opposite directions. The water main brings clean water from the utility INTO your home. The sewer line carries wastewater FROM your home out to the sewer or septic.

‍

If you're seeing wet spots in the yard, it could be either one — the clue is usually the smell. Sewer leaks smell like sewage. Water main leaks smell like nothing at all, just water. If you're not sure, we'll figure it out during the inspection.

See our water main repair page for supply-side issues.

‍

What to Do While You Wait for a Plumber

‍

If you suspect a sewer line issue, a few things can help before we arrive:

‍

• Stop running water into affected drains if possible
• If sewage is backing up into the home, turn off water at the main and call us right away
• Note which drains are affected and which are still working — helps us diagnose faster
• Take photos of any wet spots or sewage in the yard for our reference
• Keep vehicles and heavy equipment off the affected area of the yard
• Don't try to plunge or snake a backed-up main line yourself — it can push the problem deeper or damage the pipe

A quick call to (843) 509-6943 and we can talk through what you're seeing.

Frequently Asked Questions

‍

Q: How do I know if the problem is a sewer line issue or something else?

‍

‍A: The clearest signs are multiple drains backing up at once, sewage smell in the yard or house, or wet/lush spots in the yard along the pipe run. If it's only one fixture or one drain acting up, it's usually a local drain issue, not the main sewer line.

‍

Q: How much does sewer line repair cost in Summerville, SC?

‍

‍A: Sewer line work generally costs more than interior plumbing because of the excavation and materials involved. A spot repair to fix one damaged section is much less than a full line replacement. We give upfront pricing after the camera inspection so you know exactly what you're paying for.

‍

Q: How long does sewer line replacement take?

‍

‍A: A spot repair usually wraps up in a day. A full sewer line replacement can take one to three days depending on the length of the run, what's above it (driveways, sidewalks, landscaping), and how deep the line is buried.

‍

Q: Will you have to dig up my whole yard?

‍

‍A: Not usually. We camera inspect first to pinpoint the damage, so we can dig a targeted trench or hole rather than tearing up the whole yard. Full replacements do require more digging, but even those we try to minimize.

‍

Q: Who's responsible for the sewer line — me or the city?

‍

‍A: In most Charleston-area municipalities, the property owner is responsible for the sewer line from the house to the city main connection at the street. That entire run is yours. The city owns the main sewer under the street. If you're not sure, we can help you figure out the responsibility line.

‍

Q: Can tree roots really damage a sewer line?

‍

‍A: Yes, and it's one of the most common causes of sewer failure in the Lowcountry. Roots find their way in through small joint gaps, then grow inside the pipe over years until they cause a full blockage or break the pipe apart. Old clay and cast iron lines are most vulnerable.

‍

Q: What's the difference between spot repair and full replacement?

‍

‍A: Spot repair fixes a single damaged section of pipe. Full replacement swaps out the entire line from the house to the connection. If the damage is isolated and the rest of the pipe is in good shape, spot repair is usually cheaper. If the line is old and multiple sections are failing, full replacement often makes more sense.

‍

Q: Are there ways to replace a sewer line without digging up the yard?

‍

‍A: Depending on the situation, trenchless methods like pipe bursting or pipe lining can replace or repair a sewer line with much less excavation. Not every job is a fit — the existing line's condition, the length, and how it's routed all affect whether trenchless works. We'll tell you if it's an option for your situation.

‍

Q: What kind of pipe do you use for sewer line replacement?

‍

‍A: PVC for most modern replacements. It's durable, resistant to root intrusion, and has a long service life. In some cases we may use other materials depending on the specific job requirements.

‍

Q: How do I prevent future sewer line problems?

‍

‍A: Some causes (age, ground movement, root intrusion in older lines) aren't fully preventable. But you can help by not flushing wipes or non-degradable products, being careful about what goes down kitchen drains, and having a camera inspection every few years if your line is aging. If you have known root problems, ongoing root treatment can slow regrowth.
