Drain Cleaning Services in St. Louis, MO

The two most common professional drain cleaning methods serve different purposes and clog severity levels. Your St. Louis plumber will recommend one based on what's causing the blockage and where it's located.

Snaking (also called drain auguring) uses a flexible, rotating cable with a cutting head to break up clogs and pull debris from the line. This method works well for hair, soap buildup, food waste, and soft blockages in sink, shower, and toilet drains. A standard drain snake costs $150–$300 in St. Louis for residential lines. It's faster, less invasive, and ideal for localized clogs in kitchen and bathroom drains.

Hydro jetting uses high-pressure water streams (up to 4,000 PSI) to blast away buildup, grease, tree roots, and mineral deposits from inside pipes. It cleans the entire interior wall of the pipe, not just the blockage, making it highly effective for recurring clogs and sewer line cleaning. Hydro jetting costs $400–$800 in the St. Louis area, depending on line length and severity. It's the preferred method for main sewer line cleaning and properties with persistent problems.

Drain cleaning prices in St. Louis vary based on the method, location of the clog, and line accessibility. Most homeowners can expect the following:

Basic drain snaking (kitchen, bathroom, or toilet): $150–$300. Emergency or after-hours service adds 25–50% to the cost. If the plumber needs to remove a P-trap or access the line from the roof, expect the higher end of this range.

Main sewer line cleaning with snaking: $250–$500. If roots or severe buildup requires hydro jetting, costs jump to $500–$1,200. Video camera inspection to locate the blockage adds $150–$250 but often saves money by pinpointing the exact problem before treatment begins.

Full-property hydro jetting and cleaning: $600–$1,500. This is often recommended for older St. Louis homes with clay pipes or recurring issues. Many plumbers offer discounts if you bundle inspection, cleaning, and repair estimates.

A sewer camera inspection is a small, waterproof camera on a cable that travels through your drain lines to show exactly what's blocking flow. St. Louis plumbers increasingly recommend this $150–$250 service before attempting major repairs, especially for sewer line issues.

The inspection video reveals tree root intrusion, broken or collapsed pipe sections, offset joints, and buildup that snaking or jetting alone won't fix. If the camera shows structural damage—common in St. Louis's older neighborhoods—you'll need excavation or pipe lining, not just cleaning. This upfront investment prevents unnecessary drain cleaning attempts and confirms whether your problem needs a deeper solution.

Sometimes a clogged drain signals a bigger problem that cleaning won't solve. Watch for these red flags:

If the clog returns within weeks, tree roots or structural damage is likely the cause. Cleaning temporarily clears the line, but roots will regrow. You'll need root removal treatments or pipe replacement. If multiple drains back up simultaneously or sewage enters your basement, the main sewer line may be blocked, offset, or collapsed. Professional inspection is essential before deciding on jetting, rooter service, or trenchless pipe repair.

In St. Louis, aging cast iron and clay pipes are prone to cracking, especially in homes built before 1970. If a camera inspection reveals broken pipe sections, you may need pipe lining or excavation rather than simple drain cleaning. Discuss repair options with your plumber after inspection results are in.

Most St. Louis plumbers start by assessing the clog—asking about what's backing up, how long it's been happening, and whether it's a single drain or the whole system. For minor clogs, they'll attempt snaking first. For sewer lines or recurring issues, they'll recommend a camera inspection.

If snaking is the solution, the technician inserts the cable, operates the cutting head to break up debris, and may pull material out or flush it through. The process takes 30–90 minutes depending on clog depth. After clearing, they may run water to confirm full flow restoration.

For hydro jetting, the plumber feeds a specialized nozzle into the line and uses controlled pressure to clean walls without damaging modern PVC pipes (caution is needed with older clay or cast iron). The entire main line can be cleaned in one service, typically taking 1–2 hours. Most plumbers video-inspect again afterward to confirm success and identify any remaining issues.
