How we work — and what we commit to

MoldCheck.pt does not receive payments, commissions, or any form of compensation from companies that sell damp treatments, anti-mold products, ventilation systems, or remediation services.

This does not mean the site cannot charge for its own legitimate services or related activities, such as independent inspections, laboratory analysis, bookings, or digital resources. It means that we do not accept money from companies whose commercial interest depends on recommending or selling remediation.

When we recommend a product, method, or service, we do so because it has scientific basis or real usefulness for the user — not because a remediation company paid us to recommend it.

All clinical and technical content on this site is grounded in peer-reviewed scientific literature or internationally recognised technical standards. Our primary sources include:

WHO Guidelines for Indoor Air Quality: Dampness and Mould (2009)

IICRC S520 — Standard for Professional Mold Remediation, 4th edition (2024)

EPA — Mold Remediation Guide

Institute of Medicine — Damp Indoor Spaces and Health (2004)

Peer-reviewed research with explicit citation

The science of indoor mold is still actively developing. There are areas where evidence is robust and well established — the causal link between dampness and respiratory symptoms, for example. There are areas where evidence is suggestive but not conclusive — CIRS, and certain neurological effects of MVOCs. And there are areas where we simply do not know.

We distinguish these categories explicitly in our content. We do not overstate scientific certainty to create urgency, nor do we downplay documented risks to avoid alarming readers.

Residential mold is a real problem with documented health consequences. It is not a fatal emergency in most cases. Writing about mold with the objective of creating disproportionate fear — whether to sell treatments or drive traffic — is a practice this site explicitly rejects.

This site does not replace professional medical advice, on-site technical assessment, or laboratory diagnosis. In health articles, this notice is displayed prominently.

We commit to reviewing and updating content when relevant new scientific evidence is published. The date of last review is indicated on each article.

If you identify a factual error in our content, contact us. We correct transparently — the original error, the correction, and the update date are all recorded.
