Pool and Spa Leak Detection in Millsboro
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak protects the pool shell and the soil around it.

Irrigation and Yard Leak Detection in Millsboro, DE
Drip and sprinkler systems are a common source of hidden water loss in most yards. A cracked lateral or a stuck valve can waste thousands of gallons before anyone notices. We test the irrigation system separately from the house and trace leaks along buried lines. Many water providers recommend checking irrigation first when bills jump in summer.

Fixture and Appliance Leak Detection in Millsboro, DE

The cost of leak detection in Millsboro can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or those requiring special equipment may be at the higher end. We provide a detailed estimate after our initial assessment.
We use a range of advanced tools including acoustic listening devices, thermal imaging cameras, specialized moisture meters, pressure testing equipment and tracer gas detectors for precise and non-invasive leak identification.
Older homes may have galvanized steel or polybutylene pipes, both known for higher leak rates due to corrosion or material degradation. Copper pipes can develop pinhole leaks over time, while PVC and PEX are usually more reliable but can still leak at fittings or due to installation errors.

We use acoustic ground microphones, thermal imaging cameras from brands like FLIR, line tracers, moisture meters and pressure test gauges. Each tool helps confirm a different type of leak. Using several together gives accurate results.
Many homeowners policies cover the cost of finding and accessing a sudden leak, though coverage varies. We provide a written report with photos to back up your claim. Check with your insurer about your specific policy.
Older galvanized steel pipes are prone to corrosion, and some older polybutylene pipes are known for early failure. However, even modern materials like copper or PEX can leak due to improper installation, high water pressure or foundation movement.
