Slab Leak Detection in Tempe, Same-Day on Most Jobs
Wet floors with no visible source. A water bill that keeps climbing. Running water you can't find. Those are slab leak signs. We find it without tearing up your floor first.
Eighteen percent of Tempe's houses were standing before 1970, and another 24.2 percent went up during the 1970s. Copper run under a slab that long ago has been carrying hard water for half a century, and that is the wear that ends as a pinhole leak.
Why Tempe Slabs Leak
Add the 1980s and you have most of Tempe. On top of the 18 percent of houses standing before 1970 and the 24.2 percent from the 1970s, another 21.9 percent went up in the 1980s, which puts the median Tempe build year at 1984. Copper laid under a slab in 1984 is 42 years old now. What has been running through it is water the City of Tempe's 2025 testing puts at 12.3 grains per gallon on average, with individual samples as high as 32.6, because the city blends Salt River water, Colorado River water and groundwater and the mix moves through the year. A pipe that spends four decades cycling between softer and much harder water is being worked on the whole time. Underneath it, Tempe's soil is alluvial and decomposed granite, ground that takes up moisture and shifts with it, and that movement works on the fittings from the outside while the water works on the pipe from the inside.
Stopping a leak is on Tempe's list of work that does not need a permit. Repiping the house is not, and that job goes through the city for a permit. Which one you are looking at is worth knowing before anybody opens concrete.
Wondering what the signs of a slab leak look like, or how we find one without tearing up your floor? Our slab leak detection page covers both, and it applies the same way in Tempe.
Frequently Asked Questions
Tempe runs about 15 to 30 minutes from our Phoenix office depending on traffic, one of the closer stops on our map. Whatever the drive turns out to be that day, the price for the work reaches you before any concrete is opened, and nothing starts until you have approved it.
Listening gear and pressure testing, before anything gets opened. A leak under a slab makes noise and changes pressure in the line, and both of those can be tracked from above the concrete. Tempe's flatness helps a little here. The city runs from about 1,140 feet at Town Lake to 1,163 downtown with no hillside in the way, so a warm patch on the floor usually means what it looks like it means. We locate first and open second.
