Sewer Line Repair vs Replacement vs Pipe Lining: What Homeowners Should Know

Your sewer camera inspection just sent a hard truth back up the line. The footage doesn’t lie—roots coming through a joint, a cracked section in the clay, an old cast iron line flaking away, or a low spot (a “belly”) holding water and debris. Maybe a chunk of pipe has failed right under your driveway, patio, or prized landscaping. The question we hear most: Do I need a spot fix, a trenchless liner, or is full replacement the only honest answer?

This is where a lot of Spartanburg and Upstate South Carolina homeowners start to sweat—and frankly, where some contractors cash in. At Dave’s Air Conditioning Plumbing & Electrical, our approach is simple: Let the camera drive the plan, not the invoice. We show you live footage, explain what’s happening, and give you clear options using our RightFirst Standard. A 10-foot failure should not automatically mean tearing out 70 feet of perfectly good pipe.

What the Sewer Camera Really Shows Homeowners

Here’s what we find in Spartanburg, Boiling Springs, Greer, Duncan, Moore, Inman, and neighboring areas when we scope a sewer line:

• Root intrusion—roots wriggling into any crack or joint near trees and shrubs.
• Cracked clay lines—found in many older neighborhoods with original tile piping.
• Cast iron corrosion and scale—buildup that narrows the flow, catching toilet paper and debris.
• Separated joints—sections forced apart by settling soil or past repairs.
• Broken, bellied, or collapsed pipe—from heavy vehicles, bad backfills, red clay settling, or shoddy past work.
• Recurring blockages in the same spot—especially right under driveways, patios, or crawl spaces.
• Multiple problem spots—old lines failing in several places, especially cast iron gone rusty and rough, or clay crumbling away.

It’s not about how old the house is; it’s about what the camera sees. And that shapes our next steps—not scare tactics or “just replace the whole thing” salesmanship.

First Things First: Clean and Inspect Before Big Decisions

If the Pipe is Structurally Solid, Start with Drain Cleaning or Hydrojetting

Often, a main line backs up simply because of:

• Grease and sludge
• Soft buildup and toilet paper clumps
• Small roots that haven’t cracked the pipe yet

If that’s you, we’ll recommend proper drain cleaning or hydrojetting first. We clear the line, then run a second camera pass to check for hidden cracks, joint separations, or deeper problems. If the pipe is sound, there’s no need to dig or line—just thorough cleaning and maybe periodic maintenance.

Sewer Camera Inspection Drives the Right Plan

After cleaning, we scope the line again. Are there cracks or voids where sludge used to be? Is a joint gapped or just covered in scale? Can we spot a belly holding water, or does flow look good after cleaning? These details decide the plan of attack.

That’s why we always recommend a sewer camera inspection before approving any repair, lining, or replacement job.

Your Main Sewer Repair Options—Explained

1. Targeted Sewer Spot Repair

What is it? Excavating only the failed pipe section, replacing it with new material, tying back into the existing line, and verifying clean flow.

When is it smart?

• Damage is limited to one spot—a broken joint, isolated crack, or offset
• Rest of the pipe is solid on the camera
• The failure is in an accessible area (not under a slab, massive tree, or pool deck)
• Backups always happen in the same place

What we do at Dave’s:

• Mark the precise location and depth with pipe locator tools
• Excavate only what’s needed—usually a small yard cut, not the whole trench
• Install new PVC or approved pipe, check grade and bedding, then reseal and camera again

When spot repair is not smart:

• There are several failures or leaks scattered throughout the line
• The pipe material itself (cast iron, old clay) is failing in multiple spots
• Severe bellies are present—a spot fix won’t correct a long, sagging run

2. Trenchless Pipe Lining (CIPP/Liner)

What is it? Installing a resin-soaked liner through a cleanout, then curing it in place to create a new “pipe within a pipe.” No major trench. Minimizes cutting up driveways, patios, or lawns.

See the details here: trenchless sewer repair and pipelining.

Steps involved:

• Run a full camera inspection to map all issues
• Clear the old pipe with high-pressure hydrojetting
• Insert and inflate a liner, then cure to form a solid, continuous new wall
• Camera the finished line to confirm flow and sealing

Best for:

• Sewer lines that have cracks, small holes, or root channels—but are still mostly intact
• Sections under driveways, patios, sidewalks, or high-end landscaping
• Limited numbers of bends and transitions (lining can’t navigate sharp turns or T’s well)

Pipe lining is NOT right if:

• The pipe is collapsed, partly missing, or massively bellied (the liner will follow the existing shape and slope—if it pools now, it will pool after lining)
• The line is full of sharp curves, T-connections, or size changes
• There are severe grade problems that cause bad flow—the liner doesn’t “lift” a belly

Why not line healthy pipe? If long stretches of your line are sound, we’ll often recommend a targeted liner or patch—there’s no reason to spend for a house-to-street liner if only one spot needs help.

3. Full Sewer Line Replacement

What is it? Digging up and replacing all or most of your sewer line, then tying in new code-compliant pipe, correcting grade, and restoring all connections.

When it’s the only honest solution:

• The line is old clay or cast iron that’s failing throughout—cracks, roots, separated joints in many spots
• Multiple backups at different places
• Long bellies or collapsed sections that cannot support either spot repair or lining
• The overall grade is off—settled lines running too flat or with too many dips
• Too many patchwork repairs or mixed materials causing problems

Our process at Dave’s:

• Camera the entire run to mark all failures and depths
• Excavate with as little impact as possible (planning the path to avoid mature trees, patios, and structures)
• Install code-approved pipe with the right slope
• Camera the new line before backfill to confirm a smooth, perfectly draining install

It’s not always necessary—if only a few feet are bad and the remaining line is sound, we’ll make that case. But when a replacement is right, we explain why and walk you through the options.

When Does Each Sewer Solution Make Sense (and When Not)

Spot repairs: Right for…

• One damaged section from roots, heavy equipment, or settlement
• Cracked clay near a tree, but the rest of the line is clean and flowing
• An obvious separated joint, often after heavy rain or yard settling

NOT right for…

• Widespread cracking, scaling, or root intrusion
• Recurring failures at new spots up and down the line

Pipe Lining (Trenchless repair): Right for…

• Long run under a driveway, patio, or landscaping
• Pipe is mostly intact with cracks, corrosion, or minor root damage
• No severe bellies, collapses, or missing sections

NOT right for…

• Massive bellies, flat grade, or constant pooling
• Collapsed or open/broken pipe where the liner can’t form
• Many transitions, sharp bends, or bad fittings

Full Replacement: Right for…

• Pipe failing along the whole run (old clay, cast iron gone bad, etc.)
• Frequent issues at multiple spots, even after past repairs
• Grade never right—settled lines, insufficient slope, or pooling
• Multiple material types creating a patchwork of issues

But not always necessary if…

• Most of the line still looks and flows great—fix or line only what’s needed

Practical: What Can You Check Before Calling Us?

• If only one toilet or sink backs up, it’s likely a local clog
• Multiple slow drains or waste in tubs/floor drains—think main sewer issue
• Yard soggy or sudden sinkholes along the sewer path? There may be a break or collapse
• If you have a cleanout, see if water sits right at the top—this usually means main line trouble

If sewage is coming up inside, stop running water and contact us immediately for emergency plumbing help.

Questions to Ask Before Approving Any Sewer Job

1. Show me the camera video—where is the problem, and how long is it?
2. Is the damage in one spot or several?
3. Why are you recommending this solution for this section?
4. What do I give up if I choose the smaller fix over a bigger job?
5. How will this repair affect my home, yard, or driveway?
6. What’s the cleanup plan?
7. What workmanship guarantee is included?

If you get vague, rushed, or single-direction answers, take your time. The camera footage should build the plan, not a script.
