Smart detection, skilled repair
Hidden leaks can cause serious damage before they’re ever visible. We use advanced detection methods to locate the source accurately, then repair it with minimal disruption — so you get answers quickly and results that last.
Problems we solve
We diagnose and resolve a wide range of leak-related issues — from visible water intrusion and hidden moisture to slab leaks and pressurized line failures.
Visible water intrusion
Water stains, dripping, or pooling from ceilings, walls, or flooring that points to an active leak above or behind the surface.
Hidden leaks
Unexplained moisture, musty odors, or mold growth that suggests water is escaping behind walls, under slabs, or within enclosed spaces.
Slab leaks
Leaks occurring beneath the foundation, often detected through warm spots on the floor, unexplained water bills, or the sound of running water.
Pressurized waterline leaks
Leaks in supply lines carrying pressurized water to fixtures, which can cause rapid water loss and damage.
Drain leaks
Slower, gravity-fed leaks in drain or waste lines that may go unnoticed until moisture damage becomes visible.
HVAC condensation leaks
Condensation buildup or drain line issues from HVAC systems that cause water intrusion in unexpected areas.
Roof leak identification
We help distinguish whether interior water damage is coming from a roof issue or a plumbing source.
Behavior-based leaks
Leaks that only appear under specific conditions — during heavy use, after rain, or when the system is under pressure.

Frequently asked questions
We use a combination of acoustic listening equipment, infrared thermal imaging, and pressure testing to locate leaks without opening surfaces. In most cases, we can pinpoint the source and recommend targeted access — not guesswork.
Standard leak detection ranges from $95 to $325 depending on the complexity of the issue and access requirements. A full pressurized waterline inspection is $298. We provide all pricing upfront before any work begins.
Most leak detections are completed within 60 to 90 minutes. If a repair is needed, we can often complete it the same day depending on the type and location of the leak.
Yes. Slab leaks are one of the most common issues we diagnose. We use acoustic and pressure-based testing to locate leaks beneath your foundation without unnecessary excavation.
We can help determine whether the water intrusion is plumbing-related or caused by a roof or exterior issue. If we confirm the source is not plumbing, we will let you know so you can contact the right contractor.
