Moisture and Mold in Puglia Homes: Prevention and Solutions
Why traditional homes hold humidity and how to keep them dry without losing character.
Puglia is dry in summer and wet in winter. Stone houses breathe with the seasons. They were built to do this. The problem starts when modern materials trap moisture inside walls that were designed to release it.
Why old homes get damp
Most traditional homes in Puglia have no damp proof course. Moisture rises from the ground through the stone. In the past lime plaster and breathable finishes let that moisture evaporate. When owners apply cement render or modern paints the wall can no longer dry. The water sits behind the surface and salts crystallise. The plaster falls off. Mold appears.
What actually works
Strip the cement render back to stone. Reapply lime-based plaster. Use breathable mineral paint. Improve cross-ventilation. Consider a localised injection damp course only where rising damp is severe. Most homes do not need it if the breathable system is restored.
Winter ventilation matters more than you think
Closed up homes between November and March are the single biggest cause of mold in Puglia. Even in winter open shutters for twenty minutes morning and evening. If the house is empty install simple humidity controlled extract fans in bathrooms and kitchens.
