Our Leak Detection Process
Initial Assessment
We review your symptoms — high water bills, wet spots, low pressure — and identify the most likely leak location.
Electronic Detection
We use acoustic listening devices and electronic amplification to pinpoint the leak without opening walls or cutting concrete.
Camera Inspection
For sewer and drain issues, we run a camera through the line to visually confirm the problem and its exact location.
Detailed Repair Quote
We provide a clear, itemized repair estimate before any work begins — no surprises.
Repair
We perform the repair using the least invasive method possible — rerouting, spot repair, or trenchless technology where applicable.
Pressure Test & Verification
We pressure test the repaired line and verify the leak is fully resolved before leaving the job site.
When Leaks Cause Bigger Problems
Undetected leaks can lead to serious water damage that requires structural repairs. If a leak has already caused damage, C.S.W. Power Solutions can handle the full restoration as a licensed general contractor — including insurance claim coordination. Leaks near your water heater may indicate the unit needs replacement. If hard water is accelerating pipe corrosion, a water softener can help prevent future leaks.
