Frequently Asked Questions
How do I know if I have a hidden water leak?
Warning signs include unexplained water bill increases, sound of running water when nothing is on, warm spots on floors, musty odors, mold growth, foundation cracks, or wet spots in your yard. We can investigate any of these symptoms.
What is a slab leak?
A slab leak is a leak in water lines running beneath your concrete foundation. They're serious because they can damage your foundation, cause mold, and waste thousands of gallons of water. Early detection is critical.
How much does leak detection cost?
Pricing depends on diagnosis, access, materials, equipment, permits or inspections, and the authorized scope. We provide the price before work begins.
Can you find leaks without tearing up my house?
Yes! Our thermal imaging and acoustic equipment can locate most leaks without any demolition. We only open walls or floors after we've pinpointed the exact location, minimizing damage and repair costs.
How long does leak detection take?
Timing depends on diagnosis, access, parts or equipment availability, permits or inspections, site conditions, and the authorized scope. The team confirms the expected schedule after evaluation.
Will my insurance cover leak detection and repair?
Many homeowner policies cover sudden and accidental leaks, including detection and repair costs. We provide detailed documentation to help with your claim. Check your specific policy for coverage details.
