- Slab Leak Detection & Repair Signs include warm spots on floors, high water bills, or foundation cracks. We use acoustic sensors and thermal imaging to pinpoint the leak and repair it with minimal disruption.

Leak Detection & Repair FAQs
How do I know if I have a hidden leak?
Look for signs like high water bills, moldy smells, damp spots, or the sound of running water when fixtures are off. These often point to leaks behind walls or under floors.
Can small leaks cause serious damage?
Yes. Even a slow drip can lead to mold, rot, and structural damage over time. Early detection is key to avoiding costly repairs.
What tools do professionals use to find leaks?
We use acoustic sensors, thermal imaging, moisture meters, and pressure testing to locate leaks without tearing into walls or floors unnecessarily.
How long does leak detection take?
Most leaks can be located within 1–2 hours, depending on accessibility and severity. Repairs may be completed the same day or scheduled based on complexity.
Is leak detection covered by homeowners insurance?
It depends on your policy. Many cover sudden or accidental leaks but not gradual damage. We’ll provide documentation to support your claim if needed.
