We use proven tools to find hidden leaks behind walls, under floors, or underground—and fix them using quality parts and lasting techniques.

What Our Leak Detection Process Looks Like

Every home or building is different, and so are the leaks. Our licensed plumbers bring years of hands-on experience to each job and use a combination of visual inspection, moisture sensors, pressure testing, and acoustic tools to track down the exact source.

We won’t tear into walls or floors unless we absolutely need to—and if we do, we’ll walk you through every step beforehand. Once we’ve found the leak, we’ll handle the repair using durable parts and reliable techniques designed to last.

Common Signs of Plumbing Leaks

Leaks don’t always make themselves obvious right away. 

If you’ve noticed any of the following, it might be time to give us a call:

  • Sudden spike in your water bill
  • Musty odors or mold growth
  • Dripping sounds when no water is running
  • Wet spots or discoloration on ceilings or walls
  • Peeling paint or warped flooring

If something doesn’t feel right, we’re here to investigate it for you. Even a small leak can cause serious damage over time if it’s not addressed.
