- Advanced Detection, We use acoustic leak detectors and thermal imaging to locate hidden leaks without needless destruction.
- Lasting Solutions, Our repairs use durable materials such as waterproof sealants, epoxy injections, and concrete patching compounds designed to hold up in varying soil conditions.

Post-Tension Slab Leak Repair in Watertown
Many newer homes are built on post-tension slabs with steel cables under high tension. Cutting into these slabs takes care and scanning to avoid hitting a cable. We use ground-penetrating radar or other scanning methods before opening the floor. When risk is too high, rerouting the plumbing is usually the safer option.

Flooring can then be restored by your flooring contractor.

The cost of foundation leak repair in Watertown, SD can vary widely, typically ranging from $500 for minor crack sealing to $5,000 or more for complex slab leaks requiring extensive excavation or re-piping. Factors include the leak's location, severity, accessibility, and the type of foundation. We provide a detailed, upfront estimate after a thorough inspection.
Warm or damp spots on the floor, cracks in tile or concrete, mildew under carpet, the sound of running water and a water meter that moves with all fixtures off are common signs. Higher water bills are often the first clue.
