How Much Does Hydro Jetting Cost in St. Louis, MO? [2026 Data]

Hydro jetting costs in St. Louis, MO, range from $333 to $571 and average $452. The area’s affordable cost of living means hydro jetting services are more cost-effective than in other cities. Keep local considerations in mind when budgeting for the job, including the size of the clog, the length of the sewer line, and whether you need an inspection.

Hydro Jetting Cost Factors 

The cost of hydro jetting in St. Louis, MO, depends on various factors. Here's how they each contribute to the estimate your plumber will provide. 

Length and Size

The length of your sewer line (as well as the complexity of the pipe layout) will impact how long it takes your pro to complete the hydro jetting service. The more time it takes to clear the clog, the higher your overall costs will be.

Extent of Clog

The total cost of your hydro jetting largely depends on how long it takes to fix your pipes. Smaller clogs take one to two hours to fix, multiple clogs in older pipes take two to three hours, and the most severe cases take three to six hours. 

About two-thirds of the homes in the city were built before 1980, with only a handful of modern homes built in the past two decades. This means that many houses in St. Louis have outdated sewer line pipes, including clay and cast iron. These pipes are more susceptible to clogs, require extra care from plumbers during hydro jetting to prevent damage, and they’re more susceptible to tree root intrusion.

Inspection

Sewer line inspections in St. Louis cost an average of $390. Since most homes were built before the 1980s, many properties have clay or cast-iron sewer lines, which means inspections are often necessary. During the inspection, your plumber will determine where and how severe your clogs are and check the condition of your pipes before hydro jetting. 

Accessibility 

Sewer lines are typically located in the crawl space, basement, or garage. When they are difficult to reach, sealed off, or obstructed, hydro jetting services will cost more because it will take your pro longer to gain access.

Plumber Pro Costs

Plumbers in St. Louis, MO, charge $80 to $200 per hour for labor. This is a job that you have to pass off to the pros. Hydro jetting requires commercial-grade equipment, and without the proper training and experience, a DIY attempt can result in injury and expensive repairs. A pro will assess your pipes, identify clogs, and clear the sewer line without causing unnecessary damage.

Does Hydro Jetting Increase Home Value?

Hydro jetting doesn’t increase your home’s value because it's a maintenance service, not a home improvement project. However, having a pro hydro jet your sewer line keeps it in good shape and prevents bigger issues from developing. Additionally, ensuring your sewer line and plumbing system are well-maintained can make your home more appealing to buyers.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
