UNDERSTAND THE SERVICE
Start with the source.
Slab leak detection focuses on plumbing beneath the concrete foundation. It is different from rainwater entering through a foundation crack. Describing when the moisture appears helps distinguish a pressurized pipe leak from drainage or waterproofing issues.
What an assessment may involve
Depending on the plumbing layout, a contractor may isolate hot and cold lines, check pressure, and use acoustic listening equipment. Thermal imaging can reveal temperature patterns, but a temperature pattern alone does not prove the precise leak location.
Before you arrange a visit
Tell the contractor which rooms are affected, whether the floor feels warm, and whether any plumbing or flooring was recently changed. Make the water meter and shutoff accessible if it is safe to do so.
Detection, access and repair
Locating a leak does not automatically mean the entire slab must be removed. Access and repair options depend on the pipe condition and findings. Agree on the detection fee, any opening of surfaces, and the repair scope before authorizing work.
Questions about slab leak detection
Does a warm floor always mean a slab leak?
No. Heating systems and sunlight can also affect floor temperature. A warm area combined with unexplained water use deserves investigation, but testing is needed.
Is detection the same as slab leak repair?
No. Detection identifies the likely source and location. Repairs, access work and restoration are separate items to discuss with the contractor.
Can a leak be found without breaking the floor first?
In some cases, listening and isolation tests can narrow the location before opening a surface. Access requirements vary by property.
