Leak Questions? We’ve Got Answers.
What are signs I have a hidden water leak?
Watch for damp flooring, mold smells, bubbling paint, dripping sounds in walls, or rising water bills with no clear cause.
How do you find leaks without opening walls?
We use acoustic sensors, infrared imaging, and pressure testing to detect leaks through floors, walls, or concrete with minimal intrusion.
Are slab leaks serious?
Yes. Left untreated, slab leaks can crack your foundation, damage flooring, and lead to costly structural repairs. Early detection is key.
How long does leak detection take?
Most inspections take 1–2 hours. If repairs are needed, we’ll discuss your options and begin work the same day when possible.
Does homeowner’s insurance cover leak repairs?
Sometimes. Insurance may cover damage caused by a leak but not the plumbing repair itself. We can provide documentation for claims.
