How to Hire a Restoration Contractor (Questions, Red Flags, Certifications)

Updated 2026-08-14

Water damage forces you to hire fast, often within hours, and that urgency is exactly what bad operators count on. The good news: separating a legitimate restoration company from a storm chaser mostly comes down to a few checks you can run before signing anything. Here is what to verify, what to ask, and what should make you hang up the phone.

The IICRC certifications that actually matter

The Institute of Inspection, Cleaning and Restoration Certification (IICRC) is the industry’s standards body. It publishes the S500 standard for water damage restoration and the S520 standard for mold remediation, and it certifies individual technicians. A company can call itself “certified” loosely, so ask which technicians hold which credentials and ask to see cards; you can also verify a firm’s Certified Firm status through the IICRC’s online locator.

Certification	Full name	What it covers	When it matters
WRT	Water Damage Restoration Technician	Water categories, extraction, basic drying science	Every water loss. This is the baseline credential
ASD	Applied Structural Drying	Drying wet structures in place with air movers, dehumidifiers, and daily monitoring	Saturated walls, hardwood floors, anything beyond a simple carpet extraction
AMRT	Applied Microbial Remediation Technician	Mold assessment, containment, negative air, HEPA filtration	Any visible mold, or water that sat longer than a couple of days
FSRT	Fire and Smoke Restoration Technician	Smoke residue chemistry, odor removal, soot cleaning	Fire losses, or water damage from firefighting efforts

WRT is the floor, not the ceiling. For a significant loss you want a crew lead with both WRT and ASD, because structural drying is where jobs go wrong: dry too little and mold follows, demo too much and your claim balloons unnecessarily. If mold is already visible, AMRT matters because containment and negative air pressure are procedural skills, not common sense. Mold can take hold within 24 to 72 hours, which is why water and mold credentials so often end up on the same job.

Verify licensing and insurance before anyone starts work

Certification and licensing are different things. IICRC credentials are voluntary industry training. Licensing is a legal requirement that varies by state.

Licensing

Some states require a general contractor or specialty license for restoration work, especially once the job includes rebuild (drywall, flooring, framing).
Several states, including Texas, Florida, New York, and Louisiana, separately license mold remediation and restrict the same company from performing both assessment and remediation on one project.
Look up the license yourself on your state contractor board’s website rather than accepting a photocopy, since licenses get revoked and photocopies do not.

Insurance

Ask for a certificate of insurance (COI) sent directly from the contractor’s insurance agent, not handed over by the salesperson. You want to see:

General liability coverage (commonly $1 million per occurrence for legitimate firms)
Workers’ compensation, so an injured technician’s claim lands on their insurer and not your homeowner’s policy
Pollution or environmental liability if mold work is involved, since standard liability policies often exclude mold

A contractor who hesitates on any of this is telling you something.

Red flags that should end the conversation

Restoration fraud spikes after every major storm. Any one of these patterns is a reason to walk away.

Door-knockers after a storm. Legitimate restoration companies are buried in work after a weather event. The person canvassing your flooded street is often an out-of-state crew that will be gone before problems surface. Take a card if you want, but run the license and insurance checks above before signing anything.

Pressure to sign an assignment of benefits (AOB) on the spot. An AOB transfers your insurance claim rights to the contractor. They can then bill your insurer directly, negotiate without you, and in some states sue your insurer in your name. There are legitimate uses, but signing in your driveway while water is still standing is how homeowners get locked into inflated scopes. A simple work authorization to begin emergency mitigation is normal; a full AOB demands a careful read, and ideally a night’s sleep, first.

Cash-only, or large cash deposits. Reputable firms bill your insurer or invoice you with normal payment terms. Demands for cash up front, especially before equipment arrives, are a classic sign the contractor does not intend to finish.

No moisture documentation. A professional dry-out is measured, not eyeballed. The crew should map moisture with penetrating and non-penetrating moisture meters, log readings daily, and often use a thermal imaging camera to find hidden wet areas. If a contractor cannot show you a daily drying log, you have no proof for your insurer that the structure reached dry standard, and no defense if mold appears later. A typical structural dry-down runs 3 to 5 days; our guide on how long structural drying takes explains what those daily readings should show.

Quotes that are wildly low or refuse to itemize. A lump-sum number scribbled on a card is not an estimate. Restoration billing is line-itemized (more on Xactimate below), and any legitimate firm can produce one.

Questions to ask before you sign

Ask these on the first call or site visit; what matters most is whether the contractor answers comfortably and specifically.

Who exactly will be on site, and what certifications do they hold? The owner’s WRT does not help you if the crew doing the work is uncertified labor.
Will you provide daily moisture readings and a final drying report? The only acceptable answer is yes.
What drying standard do you follow? You are listening for IICRC S500 (and S520 if mold is involved).
How do you determine what gets demolished versus dried in place? Good firms dry in place when materials allow it; demo-happy firms inflate scope.
Do you bill my insurance company directly, and do you use Xactimate? See the next section.
What happens if my insurer approves less than your invoice? Get the answer in writing before work starts, not after.
Do you handle rebuild, or only mitigation? Neither answer is wrong, but you need to know whether a second contractor is coming.
What equipment will you place, and for how long? Expect specifics: air movers, low-grain refrigerant (LGR) dehumidifiers, and HEPA air scrubbers if there is contamination. Equipment typically bills per unit per day, roughly $25 to $45 for an air mover and $60 to $125 for a dehumidifier, so count and duration drive much of your bill.

How billing works with your insurance

Nearly every restoration contractor and every major insurer estimates with the same software: Xactimate. It prices each line item (extract water, remove drywall to 2 feet, run one dehumidifier for one day) against a regional price list that updates monthly. This has two practical consequences.

First, you rarely negotiate raw prices. If the contractor’s and the adjuster’s estimates disagree, the dispute is usually about scope (how many days of drying, how much drywall removed), not unit pricing. Second, the paper trail is everything: the moisture logs, photos, and psychrometric readings your contractor keeps justify each line item when the adjuster reviews the file, another reason the no-documentation red flag is disqualifying.

The typical flow: you pay your deductible, the contractor bills the insurer for the approved scope, and any additional work discovered mid-job goes in as a supplement for approval before it happens. If a contractor tells you they will “waive your deductible,” that is insurance fraud in most states, and you are the one signing the claim. For the claim side of this process, see our guide to filing a water damage insurance claim.

To sanity-check any estimate you receive, run your situation through our water damage cost calculator and compare against state-by-state cost data, since labor and equipment rates vary meaningfully by region.

Get a second opinion on big scopes

For a small loss (one room, clean water, caught quickly), a second estimate usually is not worth the delay. For a large one, it almost always is.

Full-gut recommendations. If a contractor wants to strip a floor to the studs, a second Xactimate estimate from an independent firm takes only a day or two to get and can differ dramatically in scope.
Mold. Whenever remediation is recommended, consider an independent industrial hygienist or licensed mold assessor to define the scope and perform post-remediation clearance testing. The company profiting from the remediation should not decide how much remediation you need; some states require this separation by law.
Disagreements with your insurer. If the contractor’s and adjuster’s scopes will not converge, you can request a re-inspection, invoke your policy’s appraisal clause, or hire a public adjuster.

A legitimate contractor does not fear a second opinion. One who threatens to walk, or claims the price only holds if you sign today, has answered your real question.

FAQ

Is an IICRC certification legally required to do restoration work?

No. IICRC certification is voluntary in every state, which is exactly why you should ask for it: it signals a company invested in training when nothing forced them to. Legal requirements come from state licensing, which you should verify separately through your state licensing board.

Should I ever sign an assignment of benefits (AOB)?

Sometimes, but never under pressure and never on the spot. An AOB can simplify billing because the contractor deals with your insurer directly, but it also transfers control of your claim. Read it fully, confirm your state’s rules (several states have restricted AOBs after widespread abuse), and remember that a limited work authorization is enough for emergency mitigation to begin.

Can I use a contractor my insurance company recommends?

Yes, and it is often fine. Insurer “preferred vendor” programs vet for insurance and credentials, but those contractors work under pricing agreements with the insurer, so some homeowners prefer an independent firm for large or disputed losses. Either way, the choice of contractor is legally yours.

What if the contractor finds mold during the dry-out?

Work in that area should pause while the scope is amended, because mold remediation follows a different standard (IICRC S520) and may require containment, negative air, and in some states a separately licensed remediator. Ask for photos, get the added scope in writing as a supplement to your claim, and consider independent testing on larger finds. Our guide to mold after water damage covers what a proper remediation looks like.

How fast do I need to hire someone?

Extraction and drying should start within the first day if possible, since mold can take hold within 24 to 72 hours on wet materials. That urgency applies to starting mitigation, not to signing a large restoration contract. It is entirely reasonable to authorize emergency extraction with one company while you take a day to vet who handles the full dry-out and rebuild.
