Leak Detection FAQ — Seattle, WA

Have questions about leak detection in Seattle, WA? Start here.

How do I know if I have a hidden water leak in my Seattle home?

Signs of a hidden water leak in Seattle homes include an unexplained increase in your monthly water bill, the sound of running water when all fixtures are off, musty or mildew odors in walls or cabinets, discoloration or bubbling paint, soft spots in walls or flooring, and visible mold growth. If you notice any of these signs, call Magnet Plumbing for professional leak detection.

What causes hidden pipe leaks in Seattle homes?

Hidden pipe leaks in Seattle are commonly caused by pinhole corrosion in copper pipes from local water chemistry, failed pipe joints from age or movement, improper original installation, high water pressure stressing pipe walls, and physical damage from renovation work. Homes built before 1990 with original copper or galvanized pipes are most susceptible to hidden leaks.

Can you detect leaks under my concrete slab in Seattle?

Yes. Magnet Plumbing provides slab leak detection throughout Seattle, WA using electronic leak detection amplifiers and thermal imaging cameras that reveal temperature anomalies caused by water escaping under the foundation. We can pinpoint slab leak locations with precision, reducing the concrete cutting needed for repair.

How do you find leaks without tearing up my Seattle home?

Magnet Plumbing uses non-invasive leak detection technology in Seattle, WA — thermal imaging cameras that reveal moisture behind walls, electronic acoustic listeners that amplify the sound of escaping water, and moisture meters that confirm wet areas without any cutting or drilling. We locate the leak first, then make only the access needed to repair it.

"Main water line burst and we had a river in the front yard. They isolated the break, got the water back on within a few hours, and replaced the section cleanly the next day. Excellent emergency response."
