Our Plumbing Services in St. Louis

From 24/7 emergency response to complete repiping, we handle every plumbing need for homes and businesses in St. Louis, MO.

Emergency Plumber

Plumbing emergencies happen day and night. Our 24/7 emergency plumbers arrive quickly with the tools and materials to handle any urgent plumbing situation — protecting your property and restoring service fast.

Trenchless Sewer Repair

Professional trenchless sewer line repair for cracks, offsets, and root intrusion. Pipe lining creates a new pipe within the old one, while pipe bursting pulls a new pipe through to replace the failed line completely.

Gas Line Repair

Professional gas line repair performed by licensed plumbers who understand gas system safety. We find the leak, repair or replace the damaged section, and pressure test the line before restoring gas service.

Sump Pump Repair

A failing sump pump during heavy rain can flood your basement in minutes. Our licensed plumbers respond quickly to repair or replace failed pumps, restore drainage, and protect your property from water damage.

Commercial Plumbing

Commercial plumbing needs are different from residential. Our plumbers understand backflow requirements, floor drain regulations, grease trap compliance, and the scheduling demands of active business operations.

Tankless Water Heater Installation

Tankless water heater installation for endless hot water without standby energy loss. We size, install, and commission all major tankless brands — and convert tank systems to more efficient tankless setups.

Slab Leak Repair

Expert slab leak detection and repair using electronic sensors and thermal imaging to pinpoint leaks under your foundation. We perform minimally invasive repairs to protect your structure and stop water waste.

Gas Leak Detection

Gas leaks are a serious safety hazard. Our licensed plumbers use professional gas detection equipment to find leaks in supply lines, fittings, appliances, and meters — and recommend immediate repairs to protect your family.

Drain Cleaning

Thorough drain cleaning that goes beyond surface blockages. We use video inspection and high-pressure water jetting to clear obstructions completely, leaving your drains flowing freely and reducing future buildup.

Leak Detection

Advanced leak detection using thermal imaging, electronic sensors, and pressure testing to find hidden leaks in walls, floors, and underground. Accurate detection prevents costly water damage and unnecessary demolition.

Grease Trap Cleaning

Regular grease trap cleaning for restaurants and food service operations. We pump and scrape grease traps on schedule and handle compliance documentation for health department inspections.

Repiping

If your home suffers from frequent leaks, low pressure, or discolored water, repiping may be the solution. We replace your entire water supply system with modern pipe materials and restore full pressure and water quality.

Water Heater Replacement

Water heater replacement with same-day or next-day installation in most areas. We remove your old unit, recommend the right size and model for your needs, and install your new water heater to code.

Water Line Repair

Expert water line repair using trenchless and conventional methods. We locate the break, recommend the most cost-effective repair approach, and restore your water service with minimal disruption to your property.

Garbage Disposal

Garbage disposal repair, replacement, and installation for kitchen sinks. We fix jammed, leaking, and failed units — or install new disposals with proper P-trap and dishwasher connections.

Sewer Camera Inspection

Video sewer inspection reveals exactly what is happening inside your sewer line — no guesswork, no unnecessary excavation. Essential for pre-purchase inspections and diagnosing recurring sewer problems.

Hydro Jetting

Hydro jetting service using high-pressure water to scour the interior of your drain and sewer lines. Removes grease, scale, tree roots, and years of buildup that mechanical snaking cannot reach.

Toilet Repair

Reliable toilet repair and installation for running toilets, phantom flushes, rocking toilets, weak flushes, and leaking seals. We diagnose the root cause and repair or replace components quickly and affordably.

Boiler Repair

Boiler repair and installation for residential and commercial hydronic heating systems. We service gas, oil, and electric boilers for reliable winter heating — diagnosing pressure, circulation, and combustion issues.

Water Heater Repair

Expert water heater repair that restores your hot water fast. From faulty thermostats and pilot light issues to anode rod replacement and sediment flushing, we fix the problem at the source for lasting results.

Faucet Repair

Expert faucet repair and installation for dripping, leaking, and hard-to-turn faucets in kitchens, bathrooms, and utility areas. We repair or replace cartridges, O-rings, seats, and stems — or install new fixtures.

Sump Pump Installation

Protect your basement before the next storm. Our plumbers install sump pumps with float switches, check valves, and battery backup systems — ready to keep groundwater out of your home reliably.

Backflow Testing

Backflow testing is required annually in many jurisdictions. We test your preventer, document the results, and submit paperwork to your local water authority — keeping you in compliance and your drinking water safe.

Sewer Line Repair

Professional sewer line repair that diagnoses the actual problem before recommending solutions. Camera inspection shows us exactly what is wrong so we can perform the least invasive, most cost-effective repair.

Pipe Repair

Professional pipe repair for leaks, corrosion, and breaks in supply lines, drain lines, and waste pipes. Our licensed plumbers diagnose the cause and perform lasting repairs using quality materials.

Frequently Asked Questions

Have questions about plumbing in St. Louis? We have answers.

How much does a plumber cost in St. Louis, MO?

Plumber rates in St. Louis typically range from $100 to $250 per hour depending on the type of work and time of day. Common jobs like drain cleaning run $150 to $300, while slab leak repair and repiping projects cost significantly more. Magnet Plumbing provides free estimates so you know the full cost before any work begins.

How can I tell if I have a slab leak in my St. Louis home?

Signs of a slab leak in St. Louis homes include unexplained increases in your water bill, warm or wet spots on the floor, the sound of running water when all fixtures are off, cracks in the foundation or walls, and low water pressure. If you notice these symptoms, call a plumber for professional slab leak detection before the damage worsens.

How do I shut off my water in a plumbing emergency in St. Louis?

Your main water shutoff valve in St. Louis is typically located near the water meter, near the front foundation, or in the basement or utility room. Turn the valve clockwise to close it. If you cannot find your shutoff or it is stuck, call Magnet Plumbing immediately — our emergency crew can help locate and operate the valve to stop water damage.

What causes low water pressure in St. Louis homes?

Low water pressure in St. Louis homes is often caused by mineral deposits clogging aerators and pipes, a partially closed shutoff valve, a failing pressure regulator, or a hidden water line leak. Corroded or deteriorated pipes in older St. Louis properties can also restrict flow significantly. A licensed plumber can diagnose the specific cause and recommend the right fix.

How do I prevent frozen pipes in St. Louis, MO?

To prevent frozen pipes in St. Louis, insulate exposed pipes in unheated areas like garages, crawl spaces, and attics. Keep cabinet doors under sinks open during cold snaps. Let faucets drip slightly during freezing temperatures. If a pipe does freeze, call Magnet Plumbing immediately rather than attempting to thaw it yourself to avoid a burst.

Is it safe to use chemical drain cleaners in my St. Louis home?

Chemical drain cleaners can damage older pipes in St. Louis homes, especially PVC, brass, or aging galvanized plumbing. The caustic chemicals can eat through pipe walls over time and are hazardous if they splash on skin or eyes. A professional drain cleaning by Magnet Plumbing is safer, more effective, and prevents pipe damage — costing less in the long run.
