Request an Inspection →Around 70% of Portugal's housing stock was built before 1990, before mechanical ventilation was standard practice (INE). Meanwhile, average relative humidity runs near 77% in Porto through winter, and regularly exceeds 70% across the Lisbon region.
The result: cold masonry walls, limited airflow, and condensation that has nowhere to go.
Mold isn't bad luck. It's the predictable outcome of older buildings meeting a humid climate, which is why diagnosing the actual cause matters more than guessing from how it looks.

~77% average winter humidity (IPMA), rising damp risk in Ribeira and Miragaia granite construction.
View Porto coverage → Elevated RiskCondensation is the main risk here; older concrete-frame buildings conduct outdoor cold straight through uninsulated structural points.
View Cascais coverage → Moderate RiskRising damp in the historic centre, condensation in mid-century apartment blocks.
