Leak detection blends science with experience. Today’s technology uses acoustic, infrared, and pressure-based tools to uncover even the smallest leaks — that’s the science.
But knowing where to search is just as important. A visible leak outside might actually be coming from deep behind a wall, posing a serious flooding risk.
That’s where our expertise makes the difference. Our certified technicians know what warning signs to look for and how to track down even the most hidden leaks.
Once we locate the source, we’ll provide a full repair estimate and explain any next steps, including whether water service may need to be temporarily shut off.

A slab leak develops beneath or within your home’s foundation, making it difficult to notice. If left untreated, the pressure from the escaping water can eventually crack or lift the concrete, weakening the foundation’s ability to support the structure.
We offer three repair methods and always begin with the least invasive option.
1. Dig a hole through the concrete straight down to the leak.
We cut a small opening in the concrete directly above the leak. Using precision tools, we access and repair the damaged pipe, then patch the opening with fresh concrete.This approach is ideal when there’s a single, isolated leak and little risk of additional failures.
2. Foundation Excavation
For more extensive damage, we use a jackhammer to expose a larger section of the foundation. We remove the compromised pipe, install new piping, and restore the concrete. While this method is the most involved — requiring planning, time, and care — it ensures long-term structural integrity when multiple leaks are likely.
3. Cured-In-Place Pipe (CIPP) Relining
This trenchless solution lets us repair the pipe from the inside. We insert a camera to locate the damage, clean the pipe, then apply a high-strength resin coating. Pressurized air forces the resin into any cracks, forming a new seamless liner within the old pipe. Even if the original pipe deteriorates further, the new lining maintains full water flow and protection.
Regardless of the method, we verify every repair using sewer and drain cameras to ensure the problem is fully resolved — with no surprises later.
