What San Marcos homeowners want to know about slab leak repair — answered by our licensed plumbers.
Common signs of a slab leak in San Marcos 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 San Marcos home are corroded or you have had multiple slab leaks, rerouting or full repiping is the more economical long-term choice.
Slab leaks in San Marcos are most commonly caused by pipe corrosion in copper lines from soil chemistry or water quality, pipe movement from soil shifting or seismic activity, poor original installation with pipes that rub against concrete, and high water pressure that stresses pipe walls over time. Older homes with copper supply lines are most susceptible.
Magnet Plumbing uses electronic leak detection equipment — acoustic listening devices, electronic amplifiers, and thermal imaging cameras — to pinpoint the leak location under your San Marcos slab before any concrete is cut. This precision means we only open the slab where necessary, minimizing repair costs and disruption.
