Portugal's housing stock wasn't built for how people live in it today.

Thick stone walls, minimal ventilation, and a damp Atlantic climate mean mold isn't rare here, it's the default state of thousands of homes.

Most people find out the hard way: a musty smell, a dark patch behind the wardrobe, a health complaint no one can explain.

Then they call a contractor who's also trying to sell them a remediation job, with no independent read on what's actually there.

We started mold.pt to break that conflict of interest.

We're building the independent standard for what a mold diagnosis in Portugal should look like.
