Water damage is one of the most common — and most expensive — homeowner insurance claims in the Pacific Northwest. Between our rainfall, our older housing stock, and the trend toward upstairs laundry rooms in newer homes, the conditions are right for leaks to cause serious damage if they're not caught early.

The good news: there are options at every price point to protect yourself.

Option 1: Under-Sink and Appliance Monitors (Most Affordable ~$50-150)

The most basic option is a small sensor you place under sinks, near water heaters, or behind appliances. These devices detect the presence of water and send you an alert on your phone. They don't stop the water — they just tell you it's there so you can act fast.

Ideal for: upstairs laundry appliances (if a washing machine in a second-floor closet leaks, you want to know immediately before it soaks through to the floor below), under kitchen and bathroom sinks.

Option 2: Single-Appliance Automatic Shutoff (~$200-300)

Step up from the basic sensor: these devices attach to a specific appliance or system and will automatically cut off the water supply to that unit when moisture is detected. Great for washing machines and water heaters located in high-risk spots.

This is my recommendation for anyone with an upstairs laundry setup. The combination of a washing machine on the second floor plus no automatic shutoff is a recipe for a very bad day.

Option 3: Whole-House Water Monitoring System (~$500-3,000+)

The most comprehensive option: a device installed by a plumber on your main water line that monitors total household water usage and automatically shuts off the entire home's water supply if it detects abnormal flow patterns — suggesting a leak somewhere in the system.

These range widely in price and sophistication. Some simply shut off; others integrate with smart home systems, track usage patterns, and identify wasteful habits. Several models are now included or discounted as part of certain home insurance policies.
