Frequently Asked Questions (FAQs)

Here’s the combined, copy/paste-ready FAQ list organized under the same headings as the Word document. I combined the current website FAQ list with the organized FAQ structure from the Word document. Source files used: current website FAQ list and Ouverson FAQ document.

​

General & Costs

1. What is trenchless sewer repair and how does it work?

Trenchless sewer repair is a modern method of fixing damaged sewer lines without digging up your yard or driveway. Using techniques like pipe lining or pipe bursting, our team accesses the damaged pipe through small entry points. A new liner or replacement pipe is then installed inside the old one, creating a seamless, durable pipe that restores full flow and function without the cost or hassle of traditional excavation.

This process is ideal for Twin Cities homes with mature landscaping, paved driveways, finished basements, or other areas where digging would be especially disruptive.

​

2. How much does a sewer inspection cost?

Ouverson Sewer & Water provides free camera inspections and estimates throughout the Twin Cities metro area, often available same day. Call us at (612) 751-6888, email office@linemysewer.com, or submit a request through our Contact Us form at linemysewer.com.

​

3. How much does it cost to repair a sewer line?

The cost to repair a sewer line depends on the type of repair, pipe length, depth, and extent of the damage. Typical residential jobs in the Twin Cities fall between $6,000 and $15,000, though costs vary significantly based on what is needed.

The single biggest cost driver is whether excavation is required. Digging up a sewer line is expensive regardless of what is done once you get there. Trenchless repair fixes the pipe from the inside, avoiding excavation entirely in cases where the pipe structure is still sound enough to line.

Typical ranges by repair type:

• Patches: $4,000 – $8,500

• Full trenchless lining (CIPP): $5,500 – $16,000+ based on pipe length

• Wye liner: price varies depending on access

• Excavation and pipe replacement: $6,000 – $25,000+ depending on depth, length, and complexity

• Excavation and liner: $8,000 – $30,000+ depending on depth, length, and complexity

• Complex excavations: $12,000 – $35,000+ depending on street cuts, deep pipes, obstructions, pipe bellies, and other site conditions

Every sewer system is different. The most accurate pricing comes from an on-site camera inspection and assessment. Ouverson Sewer & Water provides free estimates and upfront pricing throughout the Twin Cities, so you know exactly what to expect before work begins.

​

4. Who is responsible for sewer line repair?

In most Minnesota cities, homeowners are responsible for the sewer lateral, which is the pipe that runs from their home to the city’s main sewer connection at the street. The city is typically responsible only for the public main line.

If you’re unsure where your responsibility begins and ends, Ouverson Sewer & Water can help you identify that during a free inspection.

​

5. Does homeowner’s insurance cover sewer line repair?

Homeowner’s insurance does not typically cover sewer line repairs caused by normal wear, corrosion, or root intrusion. However, if the damage was caused by a covered event, such as a fallen tree, it may be eligible.

Some Minnesota insurers offer sewer line coverage add-ons that provide additional protection. We recommend checking with your insurance company on the specifics of your policy.

​

6. Why should I choose Ouverson Sewer & Water over other sewer repair companies?

Several things genuinely set us apart:

• We’ve been doing this longer than almost anyone in the Twin Cities. Ouverson was founded in 1969 and was among the first companies to perform trenchless sewer lining in Minneapolis, starting in 2007. That’s nearly two decades of trenchless-specific experience, and it shows in the complexity of work we’re able to take on.

• We use better materials. Not all sewer liners are equal. Ouverson uses premium liner materials that are thicker, harder, and more durable than standard options used by many competitors. They cost more but produce a better result. Our materials carry a 50-year design life.

• We do more precise work. Trenchless lining requires skill and attention that varies significantly across crews. Ouverson’s crews line sewers all the way to the city main connection — the section where some competitors stop short. An unlined section near the connection remains a vulnerability. Our wye liner expertise allows us to protect that final connection point.

• We back our work with a 5-year workmanship warranty. Most sewer contractors offer 30 days to 2 years. Our 5-year workmanship warranty is stated on every estimate and invoice. It’s not offered only on request, not at an added cost, and not buried in fine print.

• Other contractors trust us too. Ouverson regularly performs trenchless lining work for competitors and general contractors throughout the Twin Cities who don’t have the equipment or expertise to do it themselves.

​

7. Is sewer repair more expensive in winter?

For trenchless lining, no. If your pipe does not require excavation, winter repairs are priced the same as any other time of year. Trenchless lining works in all four Minnesota seasons and is unaffected by frozen ground.

The risk in winter is what happens if you wait. A pipe with root intrusion or cracking that is manageable in the fall can deteriorate significantly through a Minnesota winter. As the ground freezes and thaws in early spring, partially frozen soil shifts and settles. A pipe that was cracked but functional can collapse when that happens, turning a planned trenchless repair into an emergency excavation.

Trenchless repair in January costs the same as in July. Waiting until March or April after a hard winter can cost significantly more or result in an emergency.

​

Services & Repairs

8. What is the difference between drain cleaning, hydro jetting, and permanent sewer repair — and which one do I need?

These are three different approaches that solve different problems. It’s important to understand what each one can and cannot do.

• Cable drain cleaning, also known as chain or rodding, uses a motorized cable with a cutting head to punch through a clog or cut back roots. It restores flow quickly, but it only clears a path through the blockage. It does not remove buildup from pipe walls and it does not fix the underlying pipe. Roots that are cut back will regrow, typically within months to a few years.

• Hydro jetting uses high-pressure water to scour the inside of the pipe, removing grease, scale, and debris more thoroughly than cable cleaning. It is still a cleaning method, not a repair. Results vary depending on pipe condition and there is no guarantee on how long relief will last. Jetting a deteriorating pipe can sometimes cause additional damage, which is why a camera inspection should always come first.

• Permanent sewer repair, such as CIPP lining or excavation, is the only option that actually fixes the pipe. Trenchless lining seals the pipe from the inside, eliminates root entry points, and creates a new surface with a 50-year lifespan. Excavation is required when the pipe has collapsed or is too deteriorated to line.

If you’ve had drain cleaning done more than once in the past few years for the same issue, or if a camera inspection shows cracks, root intrusion, or deteriorating pipe material, you’re likely past the point where cleaning provides lasting relief. A camera inspection is the only reliable way to know what you’re dealing with. Ouverson Sewer & Water provides free inspections throughout the Twin Cities, often same day.

Note: Ouverson Sewer & Water does not offer standalone drain cleaning services. We provide camera inspections and permanent sewer repair.

​

9. Why are tree roots in my sewer line a problem and why is cleaning only a temporary fix?

Roots find sewer lines because pipes are a source of water, warmth, and nutrients. Once a root finds even a hairline crack or slightly separated joint, which are common in aging clay tile pipes throughout Minneapolis and the first-ring suburbs, it pushes through and begins growing inside the pipe. Cable drain cleaning cuts the roots back and restores flow, but the root structure surrounding the pipe remains intact and keeps growing.

Most homeowners don’t realize that roots don’t just grow inward. They also expand around the outside of the pipe. As they thicken over years, they exert enough pressure on clay tile to crack it further, sometimes splitting pipe sections apart entirely. What starts as a slow drain that gets cleaned every year or two can quietly be causing structural damage that eventually requires excavation to fix.

Root intrusion also causes inflow and infiltration, also known as I&I, where cracked pipes allow groundwater to seep into the sewer system, adding volume to the city’s wastewater infrastructure and contributing to backups during heavy rain events. Many Twin Cities municipalities actively monitor I&I and have programs to help homeowners address it.

The only permanent fix is repairing or relining the pipe itself. CIPP lining creates a seamless interior surface that eliminates root entry points and prevents future intrusion, provided that the liner extends all the way to the city main connection. Even a short unlined section at the end of the pipe remains a vulnerability. This is why Ouverson lines to the connection point and offers wye liners to protect that final section.

​

10. What is the difference between a spot repair, patch, and a full liner?

A spot repair, or patch, addresses a specific section of pipe, typically two to four feet, where there is localized damage such as a crack or broken joint. In the right situation, it can be a legitimate repair.

In practice, however, pipes do not usually fail in just one place. Clay tile and older pipe materials often deteriorate along their entire length, and a camera inspection that shows one problem area often reveals a pipe that is generally compromised. Patching one section while leaving the rest of an aging pipe in place is a bit like patching one spot on a failing roof — you may find yourself back in the same situation sooner than expected.

A full liner, also known as CIPP, runs the full length of the pipe and is the right choice when there is deterioration, root intrusion, or aging pipe material throughout. It provides a seamless interior surface that resists future root intrusion and carries a 50-year design life.

Ouverson Sewer & Water will always show you the full camera footage and give you an honest assessment of whether a patch makes sense or whether a full liner is the smarter long-term investment. Sometimes an inspection shows a good pipe and we will let you know that no repair is required.

​

11. What are the differences between a sewer liner, patch, and wye liner?

• Sewer Liner (CIPP): A continuous liner installed through the full length of a pipe to seal cracks, leaks, and root intrusions, creating a new pipe inside the old one.

• Sewer Patch: A localized repair targeting a specific damaged section without lining the entire pipe.

• Wye Liner: A specialized liner that repairs or reinforces the connection point where a branch line meets the main sewer line. This is often the most overlooked section of a residential sewer line.

Ouverson Sewer & Water is a regional expert in wye liners and completes these projects for residential and commercial customers throughout Minnesota, the Midwest, and the U.S.

​

12. What is the difference between preventative sewer maintenance and an emergency repair — and what does it cost?

The difference is significant in both urgency and price.

Preventative maintenance means addressing a known issue, such as root intrusion, a cracked pipe, or recurring slow drains, before the pipe fails. In most cases, this means trenchless lining, which fixes the pipe from the inside without excavation. It is planned, scheduled, and priced accordingly.

An emergency repair happens when a pipe has already collapsed or failed structurally. At that point, trenchless lining alone is no longer an option. Excavation is required to access and replace the damaged section before lining can occur.

Depending on where the collapse is, costs can be two to three times higher than a planned trenchless repair. A job that might have cost $7,000 to $9,000 as a preventative liner can reach $20,000 to $30,000 or more once excavation, street restoration, permits, and traffic control are factored in, particularly if the collapse is under a street, driveway, or bus route.

Ouverson does not charge an emergency surcharge. Higher emergency costs reflect the actual cost of excavation and related work, not an added fee. The best way to avoid an emergency is a camera inspection before a problem becomes a crisis. This is why Ouverson offers free camera inspections throughout the Twin Cities.

​

13. Can trenchless sewer repair fix a “belly” or sag in the pipe?

It depends on severity. A minor belly — a slight sag where water pools but still drains — can often be lined successfully. The liner conforms to the existing pipe shape and seals cracks or deterioration, restoring flow even if the grade is not perfect.

A severe belly, where waste is actively collecting and the pipe has significantly dropped or shifted, may require partial excavation to correct the grade before lining. Ouverson’s crews have the experience to line pipes that many other contractors would recommend excavating outright, but we ultimately want the best solution for the homeowner. We’ll always show you the camera footage and explain what we’re seeing before recommending a course of action.

​

14. Do you also repair and install water lines?

Yes. Ouverson Sewer & Water provides water line repair, replacement, and new installation throughout Minnesota and the Minneapolis-St. Paul metro area, typically in conjunction with sewer line repairs.

​

Trenchless Repair

15. Is trenchless sewer repair cheaper than excavation?

In most cases, yes. Trenchless sewer repair eliminates the need for major digging, which removes the cost of heavy equipment, extensive labor, and surface restoration. Trenchless projects are faster, less disruptive, and can be completed in all four Minnesota seasons at no additional cost.

Homeowners in Minneapolis, St. Paul, and surrounding suburbs typically save thousands of dollars by choosing trenchless over excavation when the pipe is a candidate for lining.

​

16. Is trenchless sewer repair worth it?

Yes. Trenchless CIPP lining is long-lasting, non-invasive, and preserves your landscaping, driveway, and sidewalks. It is especially well-suited to Minnesota homes with mature trees, hardscaping, or finished spaces above the sewer line.

Ouverson uses premium liner materials with a 50-year design life and backs every job with a 5-year workmanship warranty, the strongest in the Twin Cities market.

​

17. How long does trenchless sewer repair last?

Ouverson’s cured-in-place pipe liners carry a 50-year material design life. The materials are engineered to resist corrosion, root intrusion, and cracking, which is especially important in Minnesota’s freeze-thaw climate.

With proper installation, a trenchless liner should outlast most of the pipe it was installed to protect.

​

Permits & Scheduling

18. Do you need a permit to repair a sewer line?

Yes. Most Minnesota cities and municipalities, including Minneapolis and St. Paul, require a permit for sewer line repair or replacement to ensure the work meets local code. Ouverson Sewer & Water handles all permitting and inspection coordination on your behalf.

Permits typically take one to three business days to process, which is factored into your scheduled repair date. Once a permit is pulled, your appointment is confirmed, the crew is scheduled, and materials are prepared. We ask for at least five business days’ notice if you need to reschedule at that stage.

​

19. Can I reschedule or cancel my repair appointment?

We understand that plans change and will do our best to accommodate. However, once your appointment is scheduled and a permit has been pulled, please give us at least five business days’ notice to reschedule, because permits, materials, and crew time are all committed at that point.

If you’re experiencing an active sewer emergency and need us sooner, call (612) 751-6888 immediately and we’ll do everything we can to respond quickly.

​

20. How long does it take to repair a sewer line?

Most trenchless sewer repairs in the Twin Cities can be completed in one day or less, depending on the length and condition of the line. In many cases, residential trenchless lining is completed in a few hours. Jobs requiring excavation typically take one full day for residential projects.

​

21. How far out are you typically booked?

Once you accept your estimate and complete the repair agreement, we will get you onto our schedule within 24 to 48 hours. Typical wait times from acceptance to repair are zero to three weeks. We prioritize urgent situations and work hard to accommodate real estate deadlines and time-sensitive repairs.

​

22. How do I request a free sewer inspection or repair estimate?

The best way to get started is to call us at (612) 751-6888, email office@linemysewer.com, or complete the Contact Us form at linemysewer.com. We offer free on-site camera inspections throughout the Twin Cities, often available same day, so you get a firsthand assessment from the team that will actually do the work.

If you already have a recent inspection video from another source, we’re happy to review it, though we typically recommend our own inspection before committing to a repair plan. Footage quality, camera angle, and site conditions vary, and we want to be confident in what we’re seeing before giving you an estimate we stand behind.

​

23. How do I start the repair process once I have an estimate?

The easiest way is to accept your estimate online using the link in the email you received. If you’re unable to accept online, you can also:

• Call us and accept verbally over the phone.

• Email or text written confirmation.

• Mail the signed estimate via USPS.

​

24. What happens after I’ve accepted an estimate?

Once you accept, our office team will reach out via your preferred contact method to explain the scheduling process, confirm your preferred dates, and give you a timeframe for the repair day.

Typical wait times are zero to three weeks. Repairs are prioritized by urgency and the order in which they are received, but we work hard to accommodate our customers to the best of our ability.

​

25. How do I pay for my sewer repair?

Payment is due when work is completed. Our foremen on site accept credit card or check.

Financing is available through GreenSky. The application must be submitted and approved before work begins. All we need is your GreenSky ID number.

If you’re using a city assessment or grant program, please let us know before the job is complete so we can bill correctly. Email your proof of approval to office@linemysewer.com.

If funds are held by a title company or escrow account, please share the correct billing information ahead of time.

​

26. How can I share feedback or compliment the crew?

We genuinely value feedback. For questions or concerns, call the office directly so we can help right away.

To share a compliment, please leave us a Google or Yelp review and mention the crew by name. We buy lunch for the crew with the most positive feedback each week.

​

Real Estate

27. Should I get a sewer inspection before buying or selling a home?

Yes. For both buyers and sellers, a sewer scope inspection is one of the most important and most overlooked steps in a real estate transaction.

Buying: A standard home inspection does not include the sewer line. A failed or damaged sewer can cost $6,000 to $20,000 or more to repair, with no visible warning signs until it backs up. A sewer scope inspection gives you the full picture before you close.

Selling: A pre-listing inspection puts you in control. You can address issues on your own timeline, price accordingly, and provide documentation to buyers, which builds confidence and speeds up closing. Problems discovered by the buyer’s inspector often lead to price reductions, repair credits, or deal delays.

Ouverson Sewer & Water provides free sewer scope inspections throughout the Twin Cities metro area, often available same day.

​

Emergencies

28. What should I do if I have a sewer emergency?

During business hours, Monday through Friday from 6:30am to 6:30pm, call us directly at (612) 751-6888. We will triage your situation and prioritize accordingly.

There are two kinds of sewer emergencies, and knowing the difference helps:

• Backups from roots or soft clogs: Slow drains, gurgling, or occasional backups usually indicate a blockage that drain cleaning can temporarily relieve. Once flow is restored, schedule a camera inspection with Ouverson so we can assess the pipe condition and provide permanent repair options.

• Collapsed or severely damaged pipe: Sewage backing up into your basement or floor drains, complete loss of drainage throughout the house, or a wet or sunken area in your yard above the sewer line may indicate a structural failure. Call us immediately during business hours.

After hours, contact Paul Bunyan Plumbing at (612) 340-1444 for emergency service. We’ll follow up first thing the next business day.

​

Inflow & Infiltration (I&I)

29. What is an I&I inspection and how does it work?

I&I stands for inflow and infiltration, which is the entry of groundwater and stormwater into sanitary sewer lines through cracks, broken joints, and deteriorating pipe. It is a significant issue in older Twin Cities neighborhoods where aging clay tile sewer laterals allow groundwater to seep into the municipal system, adding volume to wastewater infrastructure and increasing the risk of backups during heavy rain.

Several Twin Cities municipalities have programs to identify and address I&I. How they work varies by city.

Free inspections coordinated through Ouverson:

In the following cities, Ouverson performs the camera inspection at no cost to the homeowner. You schedule directly with us, we coordinate results with your city, and if a repair is required, we’ll walk you through your options and provide a free estimate:

• Orono

• Mounds View

• West St. Paul

• Arden Hills

• St. Anthony Village

• Tonka Bay

City grant and assessment programs:

Minneapolis and St. Paul have programs that help homeowners fund sewer lateral repairs through city grants or special assessments. If you’re in Minneapolis or St. Paul and are facing a sewer repair, it’s worth checking with your city to see whether you qualify for financial assistance before committing to a repair plan.

Ouverson works with homeowners navigating these programs and will coordinate with whatever funding source applies to your situation.

If your city isn’t listed above, call us at (612) 751-6888. Programs and requirements vary by municipality, and we can help you understand what applies to your situation.

​

Common Service Areas

30. Are there neighborhoods in the Twin Cities with more sewer problems than others?

Yes, significantly. The biggest predictor of sewer problems is pipe age and material. Clay tile and Orangeburg pipe, common in areas built before the 1970s, are far more prone to root intrusion, cracking, and structural deterioration than modern PVC.

Older Minneapolis and St. Paul neighborhoods and first-ring suburbs have the highest concentration of these materials and the highest volume of sewer repairs.

Based on our job history, the zip codes where we see the most sewer work are roughly:

• 55410 — Fulton, Linden Hills

• 55419 — Tangletown, Kenny

• 55407 — Powderhorn, Bancroft

• 55416 — Morningside, St. Louis Park, Minikahda Vista

• 55417 — Nokomis, Diamond Lake

• 55406 — Longfellow, Cooper

• 55427 — Golden Valley, Crystal

• 55112 — Arden Hills, Mounds View

• 55113 — Roseville, Arden Hills

• 55343 — Minnetonka, Hopkins

• 55423 — Richfield

If your home was built before 1970 and you haven’t had a sewer inspection recently, it’s worth knowing what you have. Ouverson offers free camera inspections throughout the Twin Cities, often available same day.

After-hours sewer emergencies: Paul Bunyan Plumbing, (612) 340-1444.
