Sewer Inspection vs Sewer Estimate

What is the difference between a Sewer Inspection and a Sewer Estimate?

A sewer inspection and a sewer estimate serve different but related purposes when it comes to evaluating and managing sewer systems. Here’s a breakdown of each:

Sewer Inspection

  1. Purpose: The primary purpose of a sewer inspection is to assess the current condition of a sewer line. This involves checking for any blockages, damages, corrosion, or other issues that might affect its functionality.

  2. Method: Inspections are typically conducted using a camera that is inserted into the sewer line. This camera provides real-time video feedback, allowing inspectors to visually examine the interior of the pipes.

  3. Outcome: The result of a sewer inspection is a detailed report that outlines the condition of the sewer pipes, highlighting any problems or potential concerns.

Sewer Repair Estimate

  1. Purpose: A sewer estimate is focused on determining the cost of repairing, replacing, or installing sewer lines. An estimate may be requested after an inspection if issues are identified, or when new construction or remodeling is planned.

  2. Method: Estimates are usually provided by plumbing contractors or sewer service companies. They will consider the scope of work needed, the materials required, labor costs, and any other logistical considerations.  A sewer repair estimate should be conducted onsite, by a specialized plumber, so that best repair practices and unique strategies can be planned for the property. Quotes that are provided without visiting the property may not be accurate. Similar to an inspection, the estimating company may also use a camera and locator that is inserted into the sewer system. 

  3. Outcome: The outcome of a sewer estimate is a detailed quote that includes the projected costs associated with the specified sewer work. This quote helps homeowners or businesses budget for necessary repairs or installations.


Sewer Inspection vs. Sewer Repair Estimate FAQ

There is an important differentiation to note, prior to addressing the frequently asked questions. A sewer inspection, performed by an independent third party that only conducts sewer inspections, is impartial and can evaluate the sewer line without bias. Their revenue is used to pay for labor equipment and equipment repairs and obtained through the inspection fees only. There is no vested interest tied to the condition of the line. Whereas, an inspection and/or an estimate, performed by a plumber has a vested interest in finding repairable issues. Additionally, they make the similar or less revenue for the inspection, but can make significantly more money from line repairs. 

Sewer Inspection FAQ


Why do I need a sewer inspection?

  • Inspections are crucial for identifying existing issues before they become major problems, ensuring that your sewer system is in good working condition, and can be particularly important before purchasing a home or after experiencing persistent sewer problems. Ideally, the sewer inspection/inspector should be different from someone that performs repairs. 

How is a sewer inspection performed?

  • A flexible rod with a high-resolution video camera on its tip is inserted into the sewer line. The camera records the condition of the sewer pipes as it travels through them, and the video is analyzed in real time by a technician.

What do you look for during a sewer inspection?

  • The inspection focuses on finding cracks, blockages, root intrusions, collapsed pipes, and other structural or functional issues within the sewer lines.

How much does a sewer inspection cost?

  • Costs can vary depending on the location, size of the property, length of the sewer pipes, and any additional services provided during the inspection. Typically, the service fee starts at $279. 

Is the person inspecting the sewer a licensed plumber?

  • Not necessarily and also not typically. Licensed plumbers are typically in very high demand. Therefore, it is not necessary to be a licensed plumber to inspect and assess the condition of the sewer line. Additionally, sewer inspectors are independent and unbiased, and therefore they do not have a vested interest in the repairs of the findings.


Sewer Repair Estimate FAQ

What is a sewer repair estimate?

  • A sewer repair estimate is a calculated approximation of the costs involved in repairing the sewer lines. This estimate usually follows an inspection that has identified specific issues.

When should I get a sewer repair estimate?

  • You should consider getting a repair estimate after a sewer inspection has identified damages or when you notice problems like frequent backups, slow drains, or unpleasant odors indicating sewer line issues.

What factors influence the cost of sewer repairs?

  • The cost can be influenced by the extent of the damage, the method of repair (e.g., trenchless repair vs. traditional excavation), accessibility of the sewer lines, and local labor rates.

How accurate are sewer repair estimates?

  • While estimates aim to be as accurate as possible, unforeseen complications can arise during repair work that might affect the final cost. However, experienced professionals provide estimates based on a thorough initial inspection and their knowledge of common issues and solutions.

Does a sewer repair estimate obligate me to hire the estimator for repairs?

  • No, obtaining an estimate does not bind you to hire the same company for repairs. It's advisable to get multiple estimates to compare prices and service offerings.

Is the person providing a sewer repair estimate licensed?

  • Sometimes. An estimator is a representative of a licensed company but may not individually licensed. 

Do I need a sewer inspection or should I just get a sewer repair estimate?

  • In some cases, if you know that the condition of the line requires repair, it may make sense to skip the inspection and move immediately to an estimate for repair/replacement. Please note, an estimator often has a financial vested interest in locating areas for repair, so be certain the line is in immediate need for repair/replacement. 

Are sewer repair estimates free/Why should I expect to pay for an estimate?

  • A professional's time is not free and there is no guarantee that the repair will be selected by the client. Someone obtaining a price estimate should expect to pay for an estimate. An accurate estimate should evaluate the best repair methodology, any nuances of the system, all possible challenges, etc. An estimate can be fairly involved and timely, and therefore cost accordingly.
