Restoration is one of the few trades where a published standard defines the job, and insurers, adjusters and Google all lean on it. The IICRC publishes three that matter here, and each one changes what your pages should say.
Water: S500. The ANSI/IICRC S500 is in its fifth edition, from 2021, and a new consensus body has begun revising it. Its scope says that finding and correcting the source of the water is the property owner’s responsibility, not the restorer’s. That one line explains much of a water company’s referral book: someone else fixes the pipe, then someone has to dry the house. It also means your water page should say plainly what you do (extract, dry, document) and that the source repair is a separate job.
Mold: S520. The fourth edition came out in 2024. Google’s water damage category mentions mold, then adds that some states require extra licenses for mold remediation or assessment. In Texas, a licensed remediation contractor works to a protocol written by a licensed Mold Assessment Consultant, and licensees must give each client and property owner the state’s Consumer Mold Information Sheet before any mold work begins. Visible mold under 25 contiguous square feet can be cleaned by people who are not licensed. A mold page should name the license you hold and the state that issued it, not only the standard you follow.
Fire and smoke: S700. The first edition was published in 2025. Its scope leaves out wildfires, chemical fires and industrial fires that pose environmental hazards, so a page that cites S700 should not be the same page selling wildfire cleanup.
Where this shows up in marketing. Because Google lists IICRC certification among the requirements for its water damage category, the certificate is no longer a footer logo; it decides whether the ad can run at all. Put certification details where a homeowner and an adjuster can both find them, name the standard on each loss page, and keep each page’s claims inside the scope of the standard it cites. An adjuster reading your site should find the same words they will see on your estimate, and a homeowner should come away knowing what happens in the first 48 hours, the window the EPA gives for drying to prevent mold growth.
