Data & sources

The data and sources behind our guides

Mold Pros Phoenix is built on primary sources, not other blogs. These are the public agencies, standards bodies, and Arizona records we cite — each with a one-line note on what we use it for. If a claim in one of our guides matters, it traces back to one of these, cited inline so you can check it yourself.

How we use them

These sources feed everything from our federal-data analysis of when Phoenix homes actually get mold to our honest Phoenix mold removal cost ranges.
