Frequently Asked Questions

What are the clearest signs I have a hidden pipe leak?

The most common signs are a sudden, unexplained jump in your water bill, the sound of running water when all taps are off, or new damp spots/mildew on walls, floors, or ceilings.

How do you find a water leak without breaking my walls?

We use advanced, non-invasive technology like thermal imaging cameras, acoustic listening devices, and specialized moisture meters to pinpoint the exact location of the leak without destructive digging.

Is leak detection service available 24/7 for urgent leaks?

Yes, if you have a severe leak (like a burst pipe), our licensed New Jersey team is available 24 hours a day, 7 days a week, for emergency detection and immediate repair.

Once the leak is found, what is the repair process?

Once we locate the leak precisely, we will propose the least disruptive repair solution, which may include replacing a small section of pipe, or in some cases, re-piping a heavily damaged line.

Why is professional leak detection better than trying to find it myself?

rofessional leak detection ensures the problem is accurately diagnosed and repaired the first time, preventing further water damage, mold growth, and high repair costs from unnecessary demolition.

Our technicians are experts at detecting and repairing leaks in all parts of your plumbing system, including interior supply lines, slab leaks, and the main water line coming into your property.

Does your service cover all areas in North New Jersey?

Can your team repair leaks in different types of pipe materials?

What can I do immediately if I suspect a major pipe leak?

The first step is to turn off the main water shut-off valve to your house to stop the flow of water, and then immediately call us at 551-899-0900 for emergency service.

Do you guarantee your pipe leak repair work?
