Mold Risk Factors in Las Cruces

These local factors explain why mold problems tend to repeat in Las Cruces, even when the visible growth gets cleaned up once.

• At 10.3 inches of yearly rain, Las Cruces homes face more mold risk from HVAC condensation and plumbing leaks than from outdoor precipitation.
• Large temperature swings can drive condensation on cooler surfaces.
• Low precipitation means indoor moisture from plumbing and cooling systems is often the main driver.
• Cooling systems create condensate that must drain properly.
• Plumbing leaks under sinks and around tubs can keep wall cavities wet.
• Bathrooms without exhaust ventilation trap moisture in interior rooms.
