Editorial Standards & Methodology

Our commitment in one sentence

We explain mold, moisture, and documentation topics accurately, cite the agency or statute behind each claim, and never invent a statistic, a health threshold, a rule, or a person.

Where our information comes from

Mold guidance in the United States comes mainly from federal agencies and state law, so those are the sources we work from:

• EPA mold and moisture guidance, including its homeowner guide to mold, moisture, and your home and its mold remediation guidance for schools and commercial buildings.
• HUD healthy homes materials on moisture, dampness, and mold in housing.
• CDC public information on mold and dampness in buildings, used for educational context, never for medical claims.
• State landlord-tenant statutes and local housing and health codes, for repair, habitability, and disclosure questions.
• State licensing program rules for mold assessment and remediation in the states that license this work, such as Texas, Florida, and New York.

Where a claim depends on an outside source, we link to a primary reference, favoring official .gov pages so you can read the guidance at its source and confirm it yourself.

No invented thresholds

There is no federal standard for an acceptable level of airborne mold, and EPA guidance says as much. So we never publish a number that pretends otherwise, and our assessments never tell you a reading is safe or unsafe. Where judgment calls depend on sampling, lab analysis, or an on-site professional, our content says so plainly instead of inventing a cutoff.

What our assessments and reports are

Our homeowner assessment organizes your own answers about what you see, smell, and have experienced in your home into an educational risk summary and a documented next-step plan. It involves no sampling and no laboratory analysis, and it does not replace a professional inspection. Our inspector tools format an inspection professional's own field findings into a client-ready report; the findings, conclusions, and professional responsibility in that report belong to the inspector who wrote it, not to us.

How we handle facts that vary by jurisdiction

Landlord-tenant obligations, disclosure duties, and mold licensing rules differ by state and city, and they change. We mark a jurisdiction's specific facts as verified only when we have read them directly from that jurisdiction's official source. For every place we have not verified yet, our guides give you an honest framework and the exact questions to ask your local housing, health, or licensing office instead of a guess dressed up as a fact.

Who writes and reviews our content

Our articles are researched, written, and edited by the MoldLedger Editorial Team, a group of writers and researchers who focus on mold, moisture, and property documentation. Every article carries this team byline and a published or updated date.

We are deliberate about what we are not. We are not physicians, industrial hygienists, licensed mold assessors, remediation contractors, or attorneys, and we do not publish content under invented expert names or fabricated credentials. When a decision calls for testing, on-site professional judgment, medical advice, or legal advice, we say so and point you to the right professional instead of pretending to be one.

How we keep content current

Each article shows when it was published and, when applicable, when it was last updated. We revisit content on a rolling basis and when we learn that agency guidance, a statute, or a licensing rule has changed. Rules still move faster than any publisher can track perfectly, so a date on this site tells you when we last reviewed a page, not that nothing has changed since. Always confirm current requirements with the agency or office that sets them before you act.

Corrections and feedback

If you spot something that looks out of date or wrong, tell us and we will check it against the source and fix it promptly. Accurate content is more valuable to us than being right the first time, and reader corrections make this resource better for the next homeowner or inspector.

Email corrections to team@moldledger.com with the page URL and what you believe should change.

Independence and how we pay for this

MoldLedger is an independent information publisher and software maker. We are not affiliated with, endorsed by, or acting on behalf of the EPA, HUD, the CDC, or any state licensing body, and we do not perform inspections, testing, or remediation ourselves. Our free homeowner assessment and guides are supported by our paid documentation products, including the one-time Case Starter, and by the subscription tools we sell to homeowners and inspection professionals. Buying anything from us is never required to read our free content, and a purchase never changes what an inspector, insurer, landlord, or court decides.
