IICRC Cert: A Homeowner's Guide for Water-Damage Work
IICRC cert, in search language, is shorthand for credentials from the Institute of Inspection, Cleaning and Restoration Certification. The IICRC publishes S500, the standard for professional water-damage restoration, and it certifies individuals (and, in some programs, firms) who complete its requirements. This website is a referral network. We do not issue an IICRC cert, we do not say 'we are IICRC certified,' and we do not certify technicians. You should ask the independent contractor about their own training and about who will be in your home.
This site is a 24/7 residential referral: it connects homeowners with independent licensed contractors and does not operate a company-owned crew or promise an arrival time. Local providers are on call 24/7.
What S500 is, and what a credential is
S500 is a procedural standard: categories of water, principles of drying, and how a professional job is organized.
Working to S500 means following those procedures. Holding an IICRC certification means a person (or a firm, where that program applies) has met IICRC's own requirements at a point in time. Those are related, and they are not identical. A careful contractor can explain which certifications their technicians hold (for example, water-restoration or applied structural drying) and how that shows up in a moisture map and a dry standard. A logo on a truck is not a substitute for that explanation.
The science of drying, including drying ceiling after water leak work, is on the structural-drying page. That page is about method. This page is about credentials and about honest wording. A blog article on S500 psychrometrics previously lived on this site; the method content belongs on the science page, and the credential content belongs here.
What you can ask, and what we will not claim
Ask: who is on site, what training they have, whether they work to S500, and how they will document dryness.
We will refer independent licensed residential contractors when they are available in your ZIP. We will not sell you an 'IICRC certified' promise from this network. Training expires and is personal; you are entitled to a current answer from the contractor. For choosing a company more broadly, see best water damage restoration company near me. For the work sequence, see the process page.
What IICRC S500 is, and what this referral network is not
ANSI/IICRC S500 is the professional standard for water-damage restoration. Contractors use it to talk about water categories, classes of water intrusion, inspection, extraction, and drying. This referral network is not IICRC-certified as a firm. We will not describe referred contractors as certified, and we do not claim that a job meets S500 just because it came through this number. If a standard matters to you, ask the contractor directly: do you work to S500 on this house, and who on the crew is trained in it?
We also do not reproduce the standard's copyrighted text. The public, useful part for a homeowner is the idea of categories, which Category 1, 2, and 3 water explains in plain language, and the idea that drying should be documented with moisture readings, which moisture mapping explains.
Questions worth asking, and how EPA guidance sits beside S500
Ask what category they assigned and why. Ask what they will remove versus dry in place. Ask how they will show you that the structure is dry. Ask who repairs the pipe or the shower so the source is actually stopped. EPA's brief mold guide sits beside that professional standard as public guidance: dry wet materials within 24-48 hours to prevent mold in most cases, do not use bleach as a routine mold-cleanup practice, and do not consider cleanup finished until the moisture problem is fixed.
Certification of a person or a firm is a credential you verify with them, not with us. Call (855) 716-3231 and give the ZIP of the house that is wet if the house is wet; a conversation about credentials can happen on the same call or on the visit. Related: the residential restoration process, how to choose a company, and water-damage assessment.
How to verify a credential without taking a website's word for it
If a contractor says a person on the crew holds an IICRC certification, you can ask the person's name and how to verify that credential with IICRC. We will not do that verification for you, and we will not say that our network's participation is the same as a certification. Participation in this referral line means a contractor takes residential water-damage calls in a ZIP, not that a standard has been audited.
The practical substitute, on the visit, is behavior that matches a professional standard: a category assigned with a reason, a scope, meters, and a drying record. EPA's public mold guide is a second, shorter checklist you can hold in your hand. Call (855) 716-3231 and give the ZIP of the house that is wet if the house is wet; have the credential conversation on the same visit. Related: choosing a company and Category 1, 2, and 3 water.
What S500 does not do
The standard does not by itself dry a house, approve a claim, or make this referral network a certified firm. It does not replace EPA's public mold guidance. It does not tell you which insurer will pay. Used well, it is a shared language for category, inspection, and drying records. Used as a marketing word on a website, it is only a claim you should verify. Call (855) 716-3231 and give the ZIP of the house that is wet if the house is wet. Related: Category 1, 2, and 3 water and the residential restoration process.
Training, and the difference between a course and a job
A person can complete a course and still skip meters on a rushed visit. A firm can hold no marketing badge and still leave a careful record. Credentials are a starting question; the job is the evidence. This referral network's own position is unchanged: we are not IICRC-certified as a firm. Call (855) 716-3231 and give the ZIP of the house that is wet.

Frequently Asked Questions
Answers about S500, who holds a certification, and what this network will and will not claim.
No. It means we can check whether a participating licensed contractor is available. Ask that contractor about credentials. We do not certify anyone.
Licensing is a state and local matter and is not the same as IICRC certification. Some jurisdictions have their own rules. Ask locally, and ask the contractor about both.
S500 is the water-damage standard. Mold has other IICRC documents and other training. A water-loss job and a mold job can meet; they are not automatically the same scope.
IICRC provides its own verification channels for credentials it issued. Use those, not a statement on a referral website.
