Slab leaks under 1990s copper supply lines
Why it happens here
The copper lines under Northgate's slab-on-grade homes are 25 to 30 years old and developing pinhole leaks. The water runs under the floor and soaks the subfloor and carpet padding for weeks before anyone notices. It is the most common hidden water damage issue in 85027 and 85053.
Our approach
We use thermal imaging cameras to map the leak path before we cut anything. Once the plumber repairs the line, we extract the trapped water, pull the wet padding, and dry the slab with floor mats and desiccant dehumidifiers. We monitor daily until the slab reads dry.
