Leak Detection in St. Helens, Oregon
A hidden water leak in a St. Helens home can go undetected for months, quietly driving up your water bill and damaging your foundation. True Flow Plumbing uses non-invasive acoustic and thermal detection to find the source without tearing your home apart.
Leak Detection in St. Helens
St. Helens' older homes — many dating to the 1910s through 1940s — have supply systems that have been carrying water for 80–100 years in some cases. When leaks develop in these systems, they often do so slowly and invisibly, behind plaster walls or under original hardwood floors that homeowners are reluctant to open. Our acoustic and thermal leak detection equipment lets us find the source precisely before any wall or floor surface is touched.
🔍 Acoustic Detection
Ground microphones and listening equipment isolate the sound of water escaping under pressure — effective through concrete slabs, soil, and finished walls.
🌡️ Thermal Imaging
Moisture changes the temperature of surrounding materials. Thermal cameras map moisture locations without breaking anything open first.
💧 Slab Leak Detection
Supply and drain lines under concrete foundations can develop leaks from soil movement, corrosion, or age. We find slab leaks precisely before any concrete is opened.
🏠 Wall & Ceiling Leak Location
Discolored drywall or ceiling staining points to a hidden leak above or behind it. We trace to the source before any surface comes down.
📊 Water Meter Analysis
An unexplained water bill spike is often the first sign of a hidden leak. We check the meter behavior and isolate the leak location systematically.
🔧 Repair After Detection
We don't just find it — we fix it. Once located, we provide a repair quote and can usually complete the repair the same visit.

Frequently Asked Questions
How do you detect a hidden leak in a St. Helens home?
We use acoustic listening equipment that detects the sound of pressurized water escaping a pipe through concrete, soil, and finished walls. Thermal imaging cameras detect temperature differences caused by moisture — useful for locating leaks behind drywall or under flooring. These tools let us pinpoint the leak location before opening anything.
What causes slab leaks in St. Helens homes?
Slab leaks occur when supply or drain lines running under the foundation develop a breach. In St. Helens, soil movement and the chemistry of the local water supply both contribute. In older St. Helens homes, galvanized and early copper lines running under slabs have been there long enough that corrosion is the primary cause. You'll often notice a slab leak as a warm spot on the floor, unexplained water bill increase, or the sound of running water when everything is shut off.
How much does leak detection cost in St. Helens?
Leak detection typically runs $150–$350 for the inspection depending on complexity and home size. If you book detection and repair together, the detection fee is often applied toward the total. We quote before we start.
