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