Frequently Asked Questions
How does professional leak detection work?
C.S.W. locates hidden leaks with electronic acoustic listening, pressure isolation testing, and thermal imaging, so the leak is pinpointed before any flooring or wall is opened. That keeps access and repair targeted instead of guessing where the water is coming from.
What are the signs of a hidden water leak?
An unexplained jump in the water bill, low pressure, warm spots on the floor, damp or warped flooring, a mildew smell, and the sound of running water when fixtures are off all point to a hidden or slab leak. Early detection limits foundation and flooring damage.
How much does leak detection cost in San Antonio?
Professional leak detection in San Antonio typically runs about $150 to $500 depending on access and method, and the fee is often credited toward the repair when C.S.W. performs the work. We confirm the price before starting.
Can you repair the leak once you find it?
Yes. C.S.W. detects and repairs hidden plumbing and slab leaks under Texas plumbing license RMP46592, including reroutes and slab access, with documentation when damage is involved. Call 210-504-9796.
