Questions About This Site

Where should I start?

If you have a leak, odor, staining, or visible growth, start with Mold Basics so you can identify the source and protect the area. If symptoms are the main concern, open the Health Effects guide first. If you are still comparing options, the Testing guide explains when a test helps and when it does not.

Is this site selling mold testing or remediation services?

No. Mold Compass is an educational resource. We publish guides, checklists, and templates, but we do not perform testing or remediation work.

How is this different from other mold information online?

We keep the advice tied to published guidance and practical next steps. The goal is to help you decide what to do, not to overwhelm you with alarm or vague theory.

What should I read first if I have an active leak right now?

Stop the water source if you can, protect the area, and document the damage. Then read our after a leak guide, followed by the remediation planning guide. If you rent, add the documentation guide next.
