When water leaks under your concrete foundation, it can cause serious damage to your Fontana, Upland, or Rancho Cucamonga home. AS Plumbing & Mechanical specializes in finding these hidden slab leaks before they destroy your floors, walls, or foundation.

Our experienced technicians use electronic leak detection equipment and acoustic listening devices to pinpoint the exact location of underground pipe leaks. This saves you money by avoiding unnecessary concrete cutting and guesswork repairs.

We serve homeowners throughout Corona, Redlands, Glendora, and all nearby communities who notice signs like warm spots on floors, unexplained high water bills, or the sound of running water when everything is turned off. These are often early warning signs of slab leaks that need immediate attention.

Our team responds quickly because we know slab leaks get worse over time. We'll locate the problem, explain your repair options, and get your plumbing system back to normal. Most leak detection services are completed the same day, giving you peace of mind and protecting your biggest investment.
