Sewer Line Repair Options: A Homeowner’s Guide

A sewer line problem has a way of making itself known at the worst possible time. A backed-up drain, a foul odor coming from the basement, or sewage surfacing in the yard are all signals that something is wrong underground, and that it probably has been for a while.

The good news is that homeowners today have more repair options than ever. The right choice depends on what’s actually happening inside the pipe, and that’s not something you can determine from the surface. This guide walks through the four primary methods for repairing sewer lines, when each one applies, what to expect from the process, and how routine maintenance can keep your sewer system working efficiently.

Start With a Camera Inspection

Before any repair decision gets made, a camera inspection of the line is the essential first step. A video camera threaded through the pipe reveals the cause and location of the problem with a level of accuracy that no surface assessment can match.

A camera inspection identifies:

• Simple clogs or heavy buildup from grease and debris
• Root intrusion and how far it’s progressed
• Cracked, offset, or separated pipe joints
• Collapsed sections or structural failures
• Pipe material, age, and overall condition

Homeowners in Bloomington, Normal, Le Roy, El Paso, Heyworth, and other Central Illinois communities with older homes and mature trees are particularly likely to find that root intrusion or deteriorating pipe material is contributing to the problem. The camera footage shows you what you’re actually dealing with, so you can match the repair method to the condition.

Consider Your Sewer Line Repair Methods

You have a few options when it comes to sewer line repairs. Here are the four most common.

Method 1: Hydro-Jetting

Hydro-jetting uses high-pressure water to clean the inside of the pipe. Rather than simply punching through a blockage, it scours the full pipe wall, removing grease, scale, sludge, and soft root growth.

It’s typically best for:

• Heavy grease and food waste buildup in kitchen lines
• Scale accumulation in cast-iron pipe
• Soft root masses and debris that return after basic snaking
• Preparing a line for trenchless repair work

What to Know About Hydro-Jetting

Hydro-jetting cleans the pipe but doesn’t repair structural damage. If the line has cracks, offset joints, or collapsed sections, cleaning alone won’t solve the problem. A post-jetting camera inspection confirms whether the pipe is structurally sound or whether further repair is needed.

Method 2: Trenchless Pipe Lining

Pipe lining, also called cured-in-place pipe lining, creates a new seamless pipe inside the existing one. A resin-saturated liner is inserted into the damaged line and cured in place, sealing cracks, leaking joints, and minor offsets without excavating the yard.

You may prefer trenchless pipe lining if you have:

• Clay tile or cast iron lines with cracks or leaking joints
• Sections running under patios, driveways, or mature landscaping
• Situations where surface disruption needs to be minimized

What to Know About Trenchless Pipe Lining 

Lining requires the existing pipe to be structurally intact enough to support the liner. A severely collapsed or deformed pipe isn’t a good candidate, and thorough cleaning beforehand is essential for the liner to bond properly.

Method 3: Pipe Bursting

When a sewer line is too deteriorated to hold a liner, pipe bursting offers a trenchless alternative to full excavation. A bursting head is pulled through the old line, breaking it up while simultaneously pulling a new pipe into place. Only two access points are typically needed.

Pipe bursting is a good solution for the following:

• Collapsed or severely deformed lines
• Orangeburg or fragile clay pipe that won’t support lining
• Long runs where open trenching would be particularly disruptive or costly

What to Know About Pipe Bursting

Pipe bursting works best when it can follow the existing line’s path. If the line has a significant belly or grade problem that needs correction, bursting won’t fix those issues. That’s where excavation becomes the better call.

Method 4: Traditional Excavation

Open-trench replacement is the most direct approach. The failed section is exposed, removed, and replaced with new pipe, with full control over grade, alignment, and the addition of cleanouts where they’re needed.

Traditional excavation is best for:

• Severe bellies, sags, or back-pitched sections
• Multiple problem areas over a long run
• Situations where rerouting the line is the better long-term solution
• Cases where pipe bursting or lining isn’t feasible

What to Know About Traditional Excavation

Excavation is more disruptive than trenchless methods, and restoration work, whether that’s concrete, asphalt, or landscaping, adds to the timeline. That said, it’s the right tool for complex situations, and it gives the most complete control over the finished result.

How to Choose the Right Method

Matching the repair method to the pipe’s actual condition is what separates a lasting fix from a temporary one. Here’s a general decision framework:

• Confirm the cause with a camera inspection before committing to any repair.
• If the pipe is structurally sound but has significant buildup, start with hydro-jetting and reassess with a follow-up camera look.
• If the pipe is intact but cracking or leaking at joints, pipe lining is worth evaluating.
• If the pipe is collapsed or too fragile to support a liner, pipe bursting is a strong trenchless option.
• If the grade is wrong, there are major bellies, or the damage is complex, plan for excavation with proper regrading.

There are also a few questions worth asking any contractor before work begins:

• Will you provide before and after camera footage?
• What is the exact scope, depth, and length of the repair?
• What warranties apply to the cleaning, lining, or replacement?
• Are permits and inspections included?
• Do you offer financing for larger replacements?

Understanding Sewer Line Repair Costs

Sewer line repair costs vary considerably based on the method, the length and depth of the affected section, access conditions, and whether permits or surface restoration are involved.

• Hydro-jetting is typically the most affordable starting point when the pipe is structurally sound, and Covenant Plumbing’s mainline drain cleaning starts at $109 with a free camera inspection included
• Pipe lining and bursting involve material and equipment costs that make them more involved than cleaning alone, but they’re often less expensive than full excavation when surface restoration is factored in
• Excavation costs increase with depth, length, and the complexity of any rerouting or restoration required

For larger sewer line repairs and replacements, Covenant Plumbing offers financing options with payment plans starting as low as $133 per month for qualified homeowners. If you’re weighing multiple bids, our Meet or Beat Pricing Guarantee applies to qualifying second opinions.

What to Expect From a Professional Sewer Visit

Knowing what a service call actually looks like helps homeowners feel prepared rather than caught off guard. When you call Covenant Plumbing for a sewer line evaluation or repair, here’s how the process typically unfolds:

1. Camera inspection: We thread a camera through the line from the cleanout or a pulled fixture and review the footage with you so you understand exactly what we’re seeing and why it matters.
2. Diagnosis and options: We explain what the camera revealed, what’s causing the problem, and what the repair options look like, including honest guidance on which method fits your situation and why.
3. Repair or cleaning: We complete the work using the appropriate method for your pipe’s condition, with attention to minimizing disruption to your property where trenchless options apply.
4. Follow-up camera check: After any cleaning or repair, we run the camera again so you can see the results directly and confirm the line is clear and sound.
5. Documentation: We provide before and after camera footage, a written scope of work, and warranty information so you have a complete record of what was done.

Extend Sewer Line Life with Preventive Care

Repair is sometimes unavoidable, but a consistent maintenance approach reduces how often it’s necessary and catches problems before they become emergencies. A few habits that make a real difference:

• Schedule routine camera inspections. For homes with mature trees nearby or older pipe materials, an inspection every one to two years gives you an accurate picture of what’s developing before it becomes a failure.
• Use enzyme drain treatments. Monthly enzyme treatments in kitchen and bathroom drains break down grease and organic material before it accumulates to a level that causes problems.
• Be selective about what goes down the drain. Grease, wipes, dental floss, and feminine hygiene products are among the leading causes of main line blockages. Keeping them out of the drain system is the single most effective preventive measure most households can take.
• Manage tree roots proactively. For properties where root intrusion is a known issue, periodic hydro-jetting combined with camera monitoring keeps the line clear and gives you early warning if intrusion is progressing toward structural damage.
• Add a cleanout if you don’t have one. A sewer cleanout makes every future service call faster and less expensive. Older homes throughout Central Illinois frequently lack accessible cleanouts, and adding one is a straightforward investment that pays for itself quickly.

Frequently Asked Questions About Sewer Line Repair

How do I know if I need cleaning or a full repair?

A camera inspection is the most reliable way to find out. If the pipe is structurally intact but has significant buildup, hydro-jetting is usually the right starting point. Cracks, leaking joints, or minor offsets typically point toward lining. Collapsed sections or severe structural damage generally require pipe bursting or excavation. The footage takes the guesswork out of that decision.

Will trenchless methods work if my yard has large trees?

In many cases, yes. Pipe lining seals the entry points roots have been using, which stops further intrusion without requiring excavation around root systems. Pipe bursting installs a new pipe along the existing path with minimal digging, often avoiding damage to mature roots entirely. A camera inspection beforehand confirms whether the pipe’s condition is a good fit for either method.

How long does sewer line repair or replacement take?

It depends on the method and the scope of the work. A straightforward hydro-jetting or lining job can often be completed in a day. More involved repairs involving pipe bursting or excavation typically take one to two days, and complex reroutes or projects requiring concrete or asphalt restoration can extend to two to four days. We’ll give you a realistic timeline before work begins.

Do you provide proof the repair is complete?

Yes. We record before and after camera footage and review it with you at the end of the job. You’ll see the cleaned or repaired section directly and can confirm the line is clear and functioning correctly before we wrap up.

Can I finance a major sewer repair?

Yes. Covenant Plumbing offers financing options for larger sewer line projects, with payment plans available for qualified homeowners. If cost is a concern, ask us about financing when you call.
