Plumbing leaks are one of the most costly and frustrating issues Burien homeowners face—especially when they’re hidden. A small leak behind a wall or under a floor may not be visible for months, but it can silently cause thousands of dollars in damage to your foundation, drywall, and flooring. In this post, we’ll break down how to spot hidden plumbing leaks, what signs to look for, and what to do before the damage becomes irreversible.

Why Hidden Leaks Are Dangerous
Unlike visible plumbing leaks under sinks or in exposed pipes, hidden leaks tend to be tucked away in walls, ceilings, crawl spaces, or underground lines. These leaks often go unnoticed for weeks or even months, leading to:
- Mold growth
- Structural damage
- Higher water bills
- Increased risk of burst pipes
According to the Natural Resources Defense Council (NRDC), the average household’s leaks can account for nearly 10,000 gallons of wasted water every year. That’s enough water to wash 270 loads of laundry.
Common Signs of a Hidden Leak
If you live in Burien and are concerned about hidden plumbing leaks, here are the top warning signs to watch for:
1. Unusually High Water Bills
If your water usage hasn’t changed but your bill has skyrocketed, it could be due to a hidden leak. Compare your current bill to the previous few months to identify any unexpected spikes.
2. Mildew or Mold Odors
Damp spots behind walls or under floors often lead to musty smells. Even if you don’t see visible mold, a persistent odor is a red flag.
3. Stains on Walls or Ceilings
Discoloration, bubbling paint, or warped drywall are all visual indicators of a leak behind the surface.
4. Low Water Pressure
When water is escaping through a leak, you may notice reduced pressure in your sinks, showers, or toilets.
5. Unusual Sounds
If you hear dripping, hissing, or tapping noises in the walls when no fixtures are running, it could signal a hidden leak in your plumbing system.
DIY Leak Detection Methods
Before you call in a professional, there are a few simple checks you can perform:
🔹 Check Your Water Meter
- Turn off all water-using appliances and fixtures in your home.
- Note the water meter reading.
- Wait one hour without using any water.
- If the meter changes, you likely have a leak.
🔹 Use Food Coloring in the Toilet Tank
To test for toilet leaks:
- Add a few drops of food coloring to your tank.
- Wait 30 minutes without flushing.
- If the bowl changes color, your toilet is leaking.
Areas Where Hidden Leaks Occur in Burien Homes
Homes in Burien—especially older properties—may have outdated plumbing materials or connections. Common leak-prone areas include:
- Behind kitchen walls
- Under bathtubs or showers
- In crawl spaces
- Slab foundations
- Basements prone to moisture
Don’t forget to inspect outdoor fixtures and irrigation systems as well. Underground leaks can affect landscaping, cause soggy patches in the yard, or lead to erosion.
