Slab Leak Detection in St. Paul

Slab leak detection is a specialized plumbing service that identifies hidden leaks beneath concrete slabs in residential or commercial properties. Property owners need this service when they notice unexplained water bills, damp flooring, or foundation issues, especially in the moist climate of the Willamette Valley where soil saturation can cause or conceal leaks.

Neglecting a slab leak can lead to severe structural damage, mold growth, and skyrocketing water bills, risking costly repairs and health hazards. Early detection prevents extensive foundation issues and minimizes property damage, saving property owners time and money.

What's included in Slab Leak Detection

Thermal imaging scans to locate temperature anomalies indicative of leaks

Acoustic leak detection using listening devices to pinpoint water sounds behind slabs

Pressure testing of the water lines to detect drop-offs suggesting leaks

Inspection of exposed piping for corrosion or damage

Soil moisture testing around the foundation to identify leak-related dampness

Use of electronic leak detection equipment to trace underground water flow
