Slow drain. Gurgling after a flush. Standing water in the tub. Sewer smell from the basement floor drain. These aren't random annoyances — they're signals from your plumbing that something needs attention.
Is This Your Problem? Find Your Drain Issue
| What You're Seeing | Most Likely Cause | DIY or Call? |
|---|---|---|
| Single slow drain — kitchen or bathroom | Localized clog — hair, grease, or soap scum | DIY first. Call if no change. |

Why Drains in St. Louis Homes Clog More Than You'd Think
A clogged drain sounds like a simple problem, and sometimes it is. A hair clog in the shower drain, a slow kitchen sink after the holidays — those are often manageable. But a lot of the drain calls that come in from St. Louis homeowners turn out to be something a plunger and a bottle of Drano aren't going to fix.
Part of that comes down to pipe age. St. Louis has a high concentration of homes built before 1940, and those homes drain through cast iron lines that have been in the ground for 80 to 100-plus years. Cast iron corrodes from the inside, and that corrosion creates rough, scaly surfaces that give grease, soap film, and debris more to grab onto. A drain that clears with a snake today will frequently reblock in the same spot two months from now — not because of what was poured down the drain, but because the pipe itself is rough enough to catch it every time. When snaking isn't enough, hydro jetting cleans the full pipe wall.
Low-flow fixtures compound the problem. When older St. Louis homes get renovated, they receive new toilets and fixtures designed to use less water per flush. Modern 1.28-gallon toilets work fine in newer PVC drain systems. In older cast iron systems with partially narrowed interiors, there often isn't enough water volume to carry waste fully clear of the rough pipe sections.
Clay sewer laterals and tree roots. The pipe running from your foundation to the city sewer main is the sewer lateral. In most pre-1960 St. Louis homes, that lateral is clay pipe — joined in sections rather than formed as a continuous pipe. Even a small gap is enough for a tree root to find. St. Louis's older neighborhoods have large, established trees with root systems that have had decades to grow toward underground water. Once roots enter a clay lateral, they grow back after clearing — which is why camera inspection is the right diagnostic step.
Mineral scale from hard water. Missouri is hard water territory. The St. Louis water supply carries dissolved calcium and magnesium that deposit inside pipes whenever water sits or flows slowly. In a kitchen drain that also handles grease, the scale acts as a base layer that grease adheres to far more readily than it would on smooth walls. This same hard water is why water heaters in St. Louis need annual flushing.
A licensed plumber brings the right equipment for the actual problem. A cable machine for localized clogs, a hydro jetter for grease buildup and mineral scale in older lines, and a camera inspection when the cause isn't clear from symptoms alone. The goal is to know what you're dealing with, fix it completely, and give you a straight answer about whether the pipe itself needs attention beyond this call.
How Drain Cleaning Works — Snaking, Jetting, and Camera Inspection
Not every clog needs the same tool. The method depends on what's blocking the pipe, where the blockage sits, and what the pipe is made of.
Cable Snaking (Drain Augering)
A flexible cable with a cutting head is fed into the drain line. It rotates and cuts through or retrieves the blockage — hair tangles, grease accumulation, small objects. Fast and effective for localized clogs within 20–40 feet of the access point. Does not clean pipe walls — it clears a channel through the obstruction.
Hydro Jetting
A high-pressure water stream — typically 1,500 to 4,000 PSI — is fed into the line via a specialized nozzle. Unlike snaking, hydro jetting removes buildup from the pipe walls: grease layers, mineral scale, and scaly corroded cast iron. The appropriate tool when a line keeps reclogging after snaking.
Camera Inspection
A small waterproof camera on a flexible cable feeds into the drain line to record what's inside — pipe wall condition, blockage location and type, whether root intrusion is present, and whether the pipe has structural issues. This is how a licensed plumber confirms what they're dealing with.

Drain Cleaning Services for Every Type of Drain
Drain problems show up in different places. Here's what's covered:
Kitchen Drain Cleaning
Grease, cooking oil, and food debris — especially problematic in St. Louis's older cast iron kitchen drain lines where corrosion roughness gives grease more surface area to cling to. Includes snaking for localized clogs and hydro jetting for recurring grease buildup.
Kitchen drain servicesBathroom Drain & Tub Drain Cleaning
Hair, soap scum, and toothpaste residue build up in bathroom sinks, tubs, and shower drains. Most bathroom clogs are within DIY reach, but recurring slowdowns or standing water that won't clear with a plunger needs professional snaking or jetting.
Bathroom drain servicesToilet Drain Service
Partial blockages causing incomplete flushing or 'flushable' wipe buildup. If a toilet backup causes water in another drain — like a shower or floor drain — that's a sewer line issue, not a toilet clog. Camera inspection is usually the right first step.
Toilet repair servicesBasement Floor Drain Cleaning
Basement floor drains carry water away from the lowest point of the home. When they back up, the first sign is often a sewer smell. A backed-up floor drain during heavy rain can signal a sewer line issue, not just a blocked drain.
Floor drain servicesMain Sewer Line Service
When multiple drains are slow simultaneously, or water backs up into one fixture when another is used, the problem is in the main sewer line. Root intrusion in clay laterals is the most common cause in older St. Louis neighborhoods. Requires camera inspection and usually cable clearing or hydro jetting.
Sewer line servicesLaundry & Utility Drain Cleaning
Washing machine drains slow from lint and detergent residue. Utility sink drains in older St. Louis homes often have narrow cast iron lines that collect debris faster than newer PVC equivalents.
Utility drain servicesWhen It's Not Just a Clog — Sewer Line Warning Signs
Most drain calls are exactly what they look like — a localized clog that clears with snaking or jetting. But some drain symptoms point to something further down the system, and missing the difference costs homeowners significantly more in the long run.
Warning signs that indicate a sewer line issue:
- • Multiple drains running slow at the same time, without a single obvious cause
- • Water backing up into one fixture when another is used (toilet flushes, water appears in the shower or floor drain)
- • Persistent sewer smell from a floor drain that doesn't clear after adding water to the trap
- • Gurgling sounds from multiple drains after a single flush or sink run
- • Ground sinking or unusually lush grass over the line running from the house to the street
If you're seeing two or more of these, the likely culprit is root intrusion in the clay sewer lateral, a bellied section where the pipe has sagged, or a partial collapse. Camera inspection is the only way to confirm.
St. Louis City homeowners should know that the City's Sewer Lateral Repair Program covers the cost of qualifying repairs to the section of the lateral line running under the public right-of-way. If camera inspection confirms the problem is in that section, that's potentially significant cost relief. A licensed plumber can walk you through what qualifies and help navigate the program.

What St. Louis Homeowners Say About Our Drain Service
"Kitchen drain had been slow for months — tried liquid drain cleaner twice, no change. Tech came out, snaked it, pulled out about two feet of grease buildup from the cast iron line. Then showed me on camera what the pipe wall looked like. Explained why it would keep happening without jetting. Got the jetting done the same visit. Drain's been clear for four months."
"Toilet would back up into the basement floor drain when flushed — every single time. Called thinking it was a toilet issue. Tech did a camera inspection, found root intrusion in the clay lateral about 30 feet out from the foundation. Cleared the roots and explained the City's sewer lateral program for the right-of-way section. Really helpful — didn't try to sell me a repair I may be able to get covered."
"Bathroom sink had been slow for two weeks. DIY snake from the hardware store barely touched it. Plumber came out, cleared it in 20 minutes, and it's been fine since. Fast, polite, no upselling. Exactly what I needed."
