Accurate Leak Detection with Non-Invasive Technology

Detecting a water leak inside walls, under concrete slabs, or beneath your foundation requires specialized tools and expertise. Our technicians in Hemet-San Jacinto Valley, CA use a combination of acoustic listening devices, thermal imaging, and moisture meters to pinpoint hidden leaks without tearing into your property.


These tools allow us to isolate the exact location of a leak—even within underground pipes or behind finished surfaces. By identifying the problem early, we help you avoid more serious structural issues, mold growth, or long-term water damage.

Slab Leak Detection and Repair

Slab leaks are among the most serious plumbing issues for homes and buildings in Hemet-San Jacinto Valley, CA. These leaks occur in water lines running beneath the concrete foundation and can be difficult to detect without the proper equipment.


Common signs include warm spots on the floor, cracks in the foundation, and high water bills with no visible cause. At Dunham & Sons, we specialize in slab leak detection using electronic amplification and line tracing to determine the leak’s exact location. Once found, we offer targeted repair options including rerouting water lines, direct access repair, or epoxy restoration—depending on the condition and location of the piping.

Pipe Leak Repair for Interior and Exterior Plumbing

Leaks in interior plumbing lines can result in wall staining, ceiling damage, or puddling around fixtures. Our team handles a wide variety of pipe leak issues in kitchens, bathrooms, laundry rooms, and utility spaces. We inspect copper, PVC, PEX, and galvanized lines for signs of corrosion, wear, or faulty connections.



For exterior plumbing lines, including main water service lines or irrigation piping, we provide trench and trenchless repair services. Whether it’s a cracked pipe in your yard or a leaking connection near your water meter, we can quickly isolate and resolve the issue while minimizing damage to landscaping or hardscaping.

Leak Repairs That Meet Code and Last Long-Term

Every repair we make in Hemet-San Jacinto Valley, CA is completed using high-quality parts and in compliance with local plumbing codes. Our goal is not only to stop the leak but to ensure your plumbing system is restored to a safe and durable condition.


In many cases, leak repair involves more than patching the damaged area. We examine adjacent fittings, joints, and supports to prevent future leaks. If the pipe material is degraded or prone to recurring failures, we may recommend partial repiping to improve overall system reliability.

Water Line Rerouting Services

In cases where the damaged section of piping is located in an inaccessible or high-risk area—such as beneath a slab or behind load-bearing walls—we may recommend rerouting the line entirely. Water line rerouting avoids unnecessary demolition and can improve future access for maintenance.


This is a common solution for slab leaks in older Hemet-San Jacinto Valley, CA homes where original copper lines are corroded or compromised. We plan new pipe paths that optimize efficiency while maintaining proper water pressure and flow.
