Professional Slab Leak Detection Services in Northwest Tucson
Many Northwest Tucson homes built from the 1970s to the 1990s have copper water lines buried in or under the concrete slab. Over decades, hard water wears copper from the inside. Pipes can also rub against gravel or concrete as expansive soil shifts, until a pinhole opens where no one can see it.
Wood's Plumbing has found and fixed leaks in the Tucson area since 1979. Slab leak detection is about locating the leak before anyone breaks concrete. We isolate hot and cold lines, test for pressure loss, and use listening and thermal tools to narrow the spot. You get a clear location, what we think caused it, and repair options with upfront prices. Finding the right spot first keeps the repair smaller and saves your flooring.
What to Know About Slab Leak Detection in Northwest Tucson
Copper under older slabs
Homes in Casas Adobes, Linda Vista and the Ina Road corridor commonly have copper buried below the floor. Age and hard water make pinhole leaks more likely in these lines.
Expansive soil movement
Clay heavy soils in parts of the region swell when wet and shrink when dry. That movement can stress pipes at points where they pass through the slab.
Hot leaks cause warm floors
A leak on the hot side often makes a warm spot on tile or concrete. Many people notice it first with bare feet or when a pet keeps lying in one spot.
Leaks that hide under tile
Older homes often have tile laid directly over the slab. Water can travel along the pipe before it surfaces, so the damp spot may not be above the leak.

Frequently Asked Questions: Slab Leak Detection in Northwest Tucson
How can I check for a slab leak myself before calling?
Turn off every faucet, appliance and irrigation line, then watch the small leak indicator on your water meter. If it keeps moving, water is going somewhere. Also look for warm floor spots, a running water sound when nothing is on, or a jump in your water bill.
Do you have to break up my floor to find the leak?
No. Detection is done with pressure tests, listening equipment and thermal imaging from above the floor. Concrete stays in place unless you choose a spot repair after we find the leak.
My house had one slab leak years ago. Should I expect more?
A second leak is fairly common in older copper systems, since the same water and age affect all of the pipe. One repair does not mean the rest is worn out. We can look at the overall line condition and help you decide on spot repair versus a reroute.
