Stucco is a popular choice for home exteriors in Mobile for its clean finish and strong durability. However, even the best stucco can develop moisture problems. Once water slips behind the surface, it doesn’t stay quiet. It can lead to mold, wood rot, and costly structural damage. That’s why it’s important to know how to check for moisture behind stucco and what steps to take if trouble shows up.

5 Ways to Check for Moisture Behind Stucco (Step-by-Step)
1. Visual Inspection
Start by taking a close look at the stucco walls as you walk around your house. Look for common signs of moisture damage, such as cracks, gaps around windows, and soft or discolored spots. Pay close attention to areas where stucco meets other materials—these are common weak points.
2. Tap Test
Gently tap on the surface using a small tool or your knuckles. A solid stucco should have a firm sound. If you hear a hollow sound, that could indicate separation or trapped moisture behind the surface.
3. Use a Moisture Meter
A moisture meter designed for masonry is used to detect the amount of water behind the surface. Pin-type meters, which use small probes inserted into the wall, give more accurate readings.
4. Drill & Probe (Invasive Testing)
For a definitive check, professionals can drill tiny holes and insert probes to test what’s happening inside. This method should only be done by experienced contractors, as it involves penetrating the surface.
5. Infrared Thermography
This advanced method uses a thermal camera to spot temperature variations that may indicate hidden water damage. It’s safe and useful for identifying problem areas without damaging the wall.
