Slab Leak Detection & Repair in Salem, OR
A warm spot on the floor, low water pressure, or a meter that won't stop running? We pinpoint slab leaks with acoustic equipment before breaking any concrete.
Why Slab Leaks Happen in Salem
A slab leak is a leak in a water line running underneath a concrete foundation, and it's a distinct diagnostic and repair situation from a leak inside a wall or yard. Salem's volcanic clay soil expands when it absorbs winter rain and contracts through the dry summer months, and that seasonal movement puts real stress on any pipe running beneath a slab. Over years, that stress can crack a fitting or wear through a section of copper pipe even without any single dramatic event causing it.
Signs You Have a Slab Leak
Warm Spot on the Floor
A localized warm area usually means a hot water line leak beneath that section.
Unexplained Water Bill Increase
A meter that keeps running is a strong sign of a leak somewhere in the system, including under the slab.
Low Water Pressure
Water escaping underground can reduce pressure at fixtures throughout the home.
Sound of Running Water
Hearing water movement beneath the floor with fixtures off is a common early sign.
Warm Spot on Your Floor?
We can usually pinpoint a slab leak without breaking concrete first.
Finding the Leak Before Breaking Any Concrete
We use acoustic listening equipment specifically calibrated for slab leaks to pinpoint the exact location before recommending any repair. That precision matters because breaking concrete in the wrong spot wastes time and money on a repair that isn't needed. Once the leak is confirmed, we discuss whether a direct spot repair or rerouting the line above the slab makes more sense for your situation.
Spot Repair vs. Rerouting
A spot repair breaks a small, targeted section of concrete to access and fix the exact leak point, which is often the faster and less invasive option for a single, isolated leak. Rerouting runs a new line above the slab or through an accessible wall path instead of repairing the original line at all, which avoids breaking concrete entirely but adds new pipe run and fixture connections. We'll walk through both honestly based on what the acoustic inspection actually finds.
What Slab Leak Repair Costs
A sudden slab leak is sometimes covered by homeowners insurance depending on the cause and your specific policy, while gradual wear typically isn't. Want your real number? Call (503) 974-3329 and describe what you're noticing, we'll schedule an acoustic inspection.

Common Questions
Usually not. Acoustic equipment pinpoints the leak first, so any concrete we break is a small, targeted area rather than an exploratory dig.
A slab leak specifically involves a line running under a concrete foundation, which needs different detection equipment and repair access than a leak in a wall or yard.
Not always, but it's one of the most common signs. An acoustic inspection can confirm whether that's the actual cause.
Sometimes, depending on the cause and your specific policy. Gradual wear from age typically isn't covered. Check your policy for details.
