Answers to frequently asked slab leak repair questions from Granite City homeowners.
Common signs of a slab leak in Granite City include unexplained increases in your water bill, warm or wet spots on floors, the sound of running water when all fixtures are off, low water pressure, cracks appearing in walls or flooring, and mold or mildew odors. If you notice any of these, call Magnet Plumbing for professional slab leak detection.
The decision depends on the pipe's overall condition, the leak location, and the cost comparison. If your copper pipes are generally in good condition and the leak is isolated, direct access repair makes sense. If pipes throughout your Granite City home are corroded or you have had multiple slab leaks, rerouting or full repiping is the more economical long-term choice.
Yes. A slab leak that goes unaddressed in a Granite City home can erode the soil under the foundation, undermine the concrete slab, cause cracks in walls and flooring, and lead to significant structural movement over time. Early detection and repair prevents these expensive secondary consequences.
Magnet Plumbing uses electronic leak detection equipment — acoustic listening devices, electronic amplifiers, and thermal imaging cameras — to pinpoint the leak location under your Granite City slab before any concrete is cut. This precision means we only open the slab where necessary, minimizing repair costs and disruption.
