Emergency Leak Detection Service
Suspected water leak emergency? Call now: (630) 346-1389

Why is professional leak detection a smart investment? Professional leak detection is a fraction of the cost of the catastrophic damage an undetected leak can cause. Without specialized equipment, finding a hidden leak often requires tearing open multiple walls or floors—destructive exploratory demolition that wastes time and money. Our non-invasive technology pinpoints the exact location of the leak using acoustic listening devices and thermal imaging cameras, allowing for surgical repairs with minimal damage to your we bring years of experience home. This systematic, scientific approach saves you thousands in unnecessary drywall, flooring, and restoration costs.
My water bill is really high, but I don't see any water. Could I have a leak? Absolutely. This is one of the most common signs of a hidden leak. A continuously running toilet, a leak in the main service line underground, or a slab leak beneath your foundation are all common culprits that waste tremendous amounts of water without visible signs. Principle Plumbing can test your water meter and use pressure diagnostics to confirm if you have a leak.
What is a slab leak and why is it serious? A slab leak is a leak in a water pipe located beneath the concrete slab foundation of your home. Signs include warm spots on the floor, the sound of running water when everything is off, or foundation cracks. These are serious leaks that require immediate professional attention because they can undermine your home's foundation and cause catastrophic structural damage.
How can I tell if I have a water leak in my house? To check for a hidden leak, make sure all water-using appliances and faucets in your home are turned off. Then go to your water meter and look at the small triangle or dial (the low-flow indicator). If it is spinning, you have a leak somewhere in your system. Call Principle Plumbing for professional leak detection to pinpoint the exact location.
What happens after you find the leak? Once we find the leak, we have the professional plumbing expertise to perform the repair correctly and efficiently. We provide a clear, upfront estimate for the most effective and least invasive repair option. Our goal is to fix your leak with the absolute minimum damage to your we bring years of experience home, saving you money on restoration costs.
