Your water bill jumped 60 percent last month. You can hear water running somewhere in the wall but cannot see anything. The bathroom ceiling has a yellow stain that gets a little bigger each week. You walk past the same spot in the yard and the grass feels squishy underfoot even though it has not rained in days. These are the moments when leak detection becomes urgent. A leak you can see is straightforward. A leak you cannot see is the one that quietly destroys flooring, drywall, foundations, and water bills until somebody finds it. Here is how leak detection actually works in NWA homes and businesses.
Have unexplained water loss or visible damage? Call Bearnwa at 479-321-1313. Leak detection is part of our complete Plumbing Services in Northwest Arkansas lineup, with 24 hour response on emergency leak calls.
What Leak Detection Covers
Water leaks. Hidden water leaks behind walls, under floors, in ceilings, in slab foundations, and in yard service lines. See our work on water leak detection services in NWA.
Slab leaks. A specific subset of water leak that occurs in the water lines running through or under concrete slab foundations. Often the most damaging type of hidden leak. See slab leak detection and repair in NWA.
Gas leaks. Natural gas or propane leaks from supply lines, appliance connections, or aging gas equipment. Different equipment, different urgency, different safety profile. See gas leak detection in NWA.
When You Need Detection Now
Call right now. Smell of gas anywhere. Active water visibly running where it should not. Ceiling sagging or showing water bulge. Flooding in basement or crawl space. Sewage or wastewater smell with no obvious source.
Call within 24 hours. Water bill spike with no obvious cause. New water stains on walls or ceilings. Damp spots on flooring. Sound of running water inside walls. Wet patches in yard or driveway.
Call within a week. Mildew smell that did not previously exist. Hot spot on floor (potential slab leak). Slightly elevated water bill over several months.
How Modern Detection Works
The old approach to finding hidden leaks was destructive. Cut open walls and ceilings, look for the leak, fix the leak, repair the walls. Cost of investigation often matched or exceeded cost of repair. Modern leak detection has changed completely. Today the work is non-invasive in most cases, using a combination of acoustic sensors, thermal imaging, electronic line tracing, pressure testing, and tracer gas. For the technology side, see our detail on non-invasive leak detection technology.
Cost Picture in NWA
| Service | Typical NWA cost |
|---|---|
| Basic leak detection visit | $185 to $385 |
| Comprehensive detection with multiple methods | $385 to $685 |
| Slab leak detection | $285 to $485 |
| Gas leak detection | $185 to $385 |
| Detection plus minor leak repair | $485 to $1,250 |
The detection itself is a small fraction of what would be spent on exploratory destruction. The savings on repair work that does not have to be done is the real economic argument for professional detection.
Why Speed Matters
Hidden water leaks compound their damage every day they continue. The first 24 hours of a slab leak under a kitchen flooring system can damage the subfloor. Day 5 the flooring needs replacement. Day 14 the lower cabinets are involved. Day 30 the drywall in the kitchen and adjacent rooms is affected. Day 60 mold remediation enters the picture.
Gas leaks have an even more urgent profile. They are a real safety issue, not just a property concern.
What You Can Do Before We Arrive
For suspected water leaks. Shut off the water main if possible. Take photos of any visible damage. Note when symptoms started.
For gas leaks. Leave the property immediately. Do not turn on or off any electrical switches. Do not light any flames. Call the gas utility and then call us.
Frequently Asked Questions
How accurate is non-invasive detection?
Combining multiple methods, accuracy is typically within a foot or two for most leak types. Some methods identify exact location.
