This page is the Minneapolis landing for Leak Detection & Repair. Housing stock: 1910s–1930s bungalows and foursquares, 1920s apartments, and new North Loop infill. Basements, not slabs, hide the supply and the stack. Soil: Glacial till and river terrace. Clay tile and cast-iron laterals take elm and maple roots. Freeze depth, not clay shrink-swell, is the winter story.
Acoustic listening, pressure tests, thermal camera, dye, repair fittings. Detection is a scoped visit. Repair is quoted once we know wall vs ceiling vs buried line.
