Introduction
Water leaks can silently damage a house for months before any visible signs appear. A leak detector alerts homeowners in real time, whether they’re at work or on vacation, preventing costly repairs and health hazards. This guide reviews the best leak-sensing devices on the market, explains where to place them, and helps you decide which one fits your needs.
Why Leak Detectors Matter
- Hidden damage: Leaks under floors, behind walls, or in crawlspaces can go unnoticed.
- Mold risk: Moisture encourages mold growth, which can cause health issues.
- Structural concerns: Water can weaken foundations and wooden beams.
- Insurance: Many policies require early detection and mitigation.
Leak detectors give instant alerts, allowing homeowners to shut off water or call a professional before damage escalates.

If a sensor’s cable can’t reach a tight spot, many models allow attaching an extra sensor via cable for extended coverage.
Choosing the Right Detector
When selecting a leak detector, consider:
| Feature | SwitchBot | Eufy | D-Link | Govee |
