How Much Does a Plumber Cost in St. Louis? [2025 Data]

St. Louis is a lower-cost city across the board, and plumber costs reflect this. Homeowners can expect to pay around $292 when hiring these pros, but costs can easily range from $169 to $420 depending on the work. While your location in the city does play a part in the bottom line, the work being performed is the single largest cost factor. Learn what impacts plumber costs in St. Louis. 

St. Louis Plumber Cost Factors

A large population, low cost of living, and stable seasons all contribute to being able to hire a local plumber in St. Louis at a discount. The city boasts plenty of talented pros across all expertise and price levels. Check the below to learn what else influences total cost.  

Project Types

Plumbing isn’t one-size-fits-all, so the project type matters a great deal. Inexpensive projects can often be handled by less experienced pros, which is a double whammy of savings. The opposite is true of big repairs like main water leaks—you want a top-notch pro for such a serious project. Check the table below for some of the average costs in St. Louis across project types.   

Frequency

While not something every homeowner thinks of, having a plumber check your home on a regular schedule can be an incredible investment decision. St. Louis doesn’t have super harsh winters, so you can skip having a plumber check the winterization of your pipes. 

Plumbing isn’t too affected in the summer, and both of these facts keep prices down. Outside of normal repairs, most homeowners in St. Louis should have a plumber check their homes once a year.

Location

It’s not uncommon for different zip codes to have different plumbing prices. While this can be due to more expensive homes having more complicated and expensive plumbing, plumbers in St. Louis who live or travel to pricier neighborhoods charge higher prices. Expect to pay a premium in Forest Park and Wydown Skinker and below-market rates in Fairground and Kingsway. 

St. Louis Plumbing Pro Costs

Earlier, we broke down the costs of the work and what a plumber might charge, but what about the cost of the plumber themselves? This is the other part when calculating costs—how much time the plumber has spent honing their skills. 

Level of Experience

The table below gives a good idea of the price ranges based on how many years a plumber has worked and what, if any, certifications they may have. Understanding the levels of plumbers will go a long way to making sure you don’t hire someone under- or overqualified for your project. 

For example, you shouldn’t hire a handyperson for an emergency plumbing repair with a heavy leak, nor should you hire a master plumber for a dripping sink. Journeyperson plumbers can handle almost every project, and if it’s very simple, apprentices are a solid call.  

Does Hiring a Plumber for Plumbing Projects Increase Home Value?

If you’re hiring a plumber to assist with a kitchen remodel, that can seriously increase your home’s value. However, hiring someone to fix some broken pipes will only help preserve the value of your home and insulate it from a price drop. 

The effect of hiring a plumber on your home’s value will come down to the project. In St. Louis, where property and home values are more modest compared to the rest of the country, you’ll want to make sure the ROI is there before considering a renovation project designed to increase value.
