How to start a water damage restoration company

This guide walks through opening a water and mold restoration company in the US: the IICRC certifications, the state mold licenses, the insurance rules that bind a restorer and the first jobs. The most useful finding is that the drying itself is unlicensed in the states checked, while the mold work, the rebuild and anything that looks like handling the claim each carry their own law.

Licensing: No state license for water drying in Texas, Florida or California; mold work is licensed in Texas, Florida and New York
First certification: IICRC Water Damage Restoration Technician: no prerequisites, $80 exam
Florida claims: Assignment of benefits is void on policies issued from January 1, 2023
Texas claims: A contractor may not act as a public adjuster on its own jobs, licensed or not
Drying window: EPA: dry wet areas within 24 to 48 hours to prevent mold
Google screening: IICRC certification required for Water damage services ads; about 3 to 4 weeks

What a restoration company does, and the ways to build one

The industry’s water standard, the ANSI/IICRC S500, draws the edge of the job: it states that finding and correcting the cause of the water “is the responsibility of the property owner and not the restorer” (IICRC S500). The restorer extracts, dries, removes what cannot be saved and documents it; someone else fixes the pipe.

Each IICRC standard is a separate service line:

Water: the S500, fifth edition, 2021, now under revision by a new consensus body.
Mold: the S520, fourth edition, 2024, which covers remediator qualifications and post-remediation verification (IICRC S520).
Fire and smoke: the S700, first edition, 2025, whose scope leaves out wildfires, chemical fires and industrial fires that pose environmental hazards (IICRC S700).

The choices a founder makes early decide which licenses apply later:

Mitigation only, or mitigation plus rebuild. Putting a house back together is construction, and Florida says so in its mold statute: a remediator “may not perform any work that requires a license under chapter 489 unless the mold remediator is also licensed under that chapter” (Fla. Stat. 468.8411).
Direct homeowners, or insurance programs. Contractor Connection, one managed repair network, describes itself as a network of “5,000 general and specialty contractors nationwide” handling “500k assignments annually,” with residential water mitigation among its services (Contractor Connection).
Franchise or independent. A franchisor must hand you its disclosure document “at least 14 calendar-days” before you sign or pay (16 CFR 436.2).

The outlook: technician pay, claim sizes and the companies already here

The federal occupation tables have no “restoration technician.” The nearest match on O*NET OnLine is Hazardous Materials Removal Workers (47-4041.00), which lists mold damage technician among its titles. From Bureau of Labor Statistics data, it puts the median wage at $23.78 an hour, or $49,450 a year, in 2025, with 51,300 people employed in 2024, growth of 1 to 2 percent projected from 2024 to 2034 and 5,000 projected openings over that decade. Treat these figures as a guide to technician pay, not a forecast of restoration demand.

Demand comes from losses, and insurers publish those. ISO data reported by the Insurance Information Institute shows that from 2019 to 2023 about one in 60 insured homes had a claim for water damage or freezing, averaging $15,400, while fire and lightning claims averaged $88,170. Those are claim totals, not a restorer’s invoice. Freezes add spikes: State Farm paid over $806 million on more than 32,000 frozen pipe and water damage claims between August 2022 and August 2023, averaging $25,000. On the coasts, the National Hurricane Center season runs from June 1 to November 30 and peaks on September 10.

No public source counts restoration companies. The Census Bureau’s NAICS index files home fire and flood restoration under Residential Remodelers, which County Business Patterns for 2023 put at 135,337 employer establishments, 81 percent with fewer than five employees.

Certification and licensing

No federal license covers water restoration, and Texas, Florida and California do not license water drying as such. The law sits at the edges: mold, the rebuild, lead and asbestos in what you tear out, and the claim.

IICRC certification

IICRC certification is voluntary, but Google requires it for Water damage services ads and insurance programs ask for it. The usual path:

Water Damage Restoration Technician (WRT). “There are no prerequisites for this certification,” it can be taken by live stream or in person, it is offered in Spanish, and it is required for the Master Water Restorer designation (IICRC WRT).
Applied Structural Drying (ASD). Requires WRT and is “In-person certification only.” IICRC pitches it partly as a way to “Pursue partnerships with TPA’s,” the third-party administrators that route insurance work (IICRC ASD).
Applied Microbial Remediation Technician (AMRT). Covers “mold and sewage remediation techniques” and also requires WRT (IICRC AMRT).
Mold Remediation Specialist (MRS). Needs at least one year of verifiable mold remediation experience, has no course attached and carries a $150 application fee (IICRC MRS).

As of October 2026 the IICRC charges $80 for an exam or a retest, or $150 for AMRT, requires annual renewal and 14 hours of continuing education every four years, and notes that certifications “follow you and not your company” (IICRC FAQ). To become an IICRC Certified Firm, a company needs current liability insurance, at least one active certified technician and a $25 application fee, then $199 a year to renew (IICRC Certified Firm application). An owner who passes WRT can certify the firm right away.

Federal rules that reach a tear-out

Lead paint. Firms “cannot advertise or perform renovation activities covered by the RRP Rule in homes or child-occupied facilities built before 1978 without firm certification,” and that “includes all firms, even sole proprietorships”; the exemption stops at six square feet of paint per room inside or 20 square feet outside (EPA RRP for contractors). A wet, painted wall cut out of an older house is usually past that. Firm certification costs $300 and lasts five years, each renovator takes an 8-hour course with 2 hours of hands-on work, and fourteen states run their own programs instead of EPA, among them Georgia, North Carolina, Oklahoma and Wisconsin (EPA state programs).
Asbestos on commercial losses. The asbestos NESHAP sets work practices for demolitions and renovations of all structures “excluding residential buildings that have four or fewer dwelling units,” and requires notice to the state agency before the work (EPA asbestos rules). An office or apartment block is in scope; a single house is not.
Trucks. A vehicle or combination rated at 10,001 pounds or more that hauls property across state lines is a commercial motor vehicle needing federal registration (49 CFR 390.5). A truck-mount towing a trailer to a storm in the next state can cross it.

State licensing for mold and rebuild work

State	Who issues it	What you need	Key requirements, as the agency states them
Texas	Texas Department of Licensing and Regulation	Mold Remediation Contractor (individual) and Mold Remediation Company licenses; no state license for water drying or general contracting	Contractor: $450, age 18, an accredited course, experience (for example five years in an allied field with a diploma), exam, criminal history check. Company: $850, an office in Texas, $1 million per occurrence general liability, a licensed contractor as responsible person
Florida	DBPR mold-related services	Mold remediator license for individuals only; a Chapter 489 contractor license for the rebuild	Above 10 square feet; four years of documented field experience, or a two-year science degree plus one; exam and fingerprints; $125 application, $100 license and $5 fees; $1,000,000 general liability with mold coverage
New York	Department of Labor mold program	Mold Remediation Contractor License for any business doing mold remediation	Above 10 square feet; age 18; an approved course; $500 fee; $50,000 liability insurance plus workers’ comp and disability where required; a four-hour refresher to renew
California	Contractors State License Board	Contractor license for rebuild work; no state mold license confirmed	A license is needed when the project requires a permit, uses other workers or totals $1,000 or more in labor and materials

Fees are as of October 2026. Check each requirement with the agency that issues it before you apply, and with your city or county for business licenses and rebuild permits.

Texas. TDLR defines remediation as “the removal, cleaning, sanitizing, or other treatment of mold or mold-contaminated matter” (TDLR mold program). Unlicensed people can usually clean visible mold under 25 contiguous square feet, but a licensed contractor gets no small-job pass: once hired, it must follow a work plan built on a protocol from a licensed Mold Assessment Consultant, whatever the size of the area. A company may hold both an assessment and a remediation license, “However, you are not allowed to conduct both mold assessment and mold remediation activities on the same project” (TDLR mold FAQ). A licensed consultant can also sign the state’s Certificate of Mold Damage Remediation, which limits how an insurer may use past mold damage, and a company using unlicensed workers cannot obtain one. The table draws on TDLR’s contractor and company application pages. One rule is moving: SB 1255, in effect since September 1, 2025, repealed the provision that let supervised employees of a license holder work without their own license, and TDLR says current rules stay in force until new ones are adopted (TDLR program update). Ask TDLR how crew members must be credentialed before you staff a mold job.

Florida. “The Department does not license mold assessment or mold remediation businesses. Only individuals are licensed to perform these services,” DBPR says. Remediation means treating mold “of greater than 10 square feet” (Fla. Stat. 468.8411), and without a related degree the license takes four years of documented field experience (Fla. Stat. 468.8413). A founder without that history hires a licensed remediator or stays under the threshold. The insurance has to name mold: at least $1,000,000 of general liability “that includes specific coverage for mold-related claims” (Fla. Stat. 468.8421). The law also bars using a mold remediator title without the license, assessing a structure your company remediated within the last 12 months, and referral payments between assessors and remediators (Fla. Stat. 468.8419).

New York. “It is unlawful for any person to engage, advertise or hold themselves out as a mold assessor, remediation contractor, or abatement worker unless they have a valid mold license” (NY DOL mold program). A mold project is anything over 10 square feet (NY DOL mold FAQ), one individual may not both assess and remediate a property, and an independent assessment defines the scope.

California. The state’s contractor law reaches the rebuild once a job crosses the $1,000 line, needs a permit or uses other workers. Ask CSLB whether its D-63 Construction Clean-up class, which covers removing drywall and plaster debris, fits mitigation demolition. A statewide mold license could not be confirmed either way.

Insurance claims: what a restorer may and may not do

Most water jobs are paid by an insurer, and states police how close a contractor gets to the claim.

Texas bars contractors from adjusting their own jobs. “A contractor may not act as a public adjuster or advertise to adjust claims for any property for which the contractor is providing or may provide contracting services,” even if it holds a public adjuster license or a power of attorney (Tex. Ins. Code 4102.163). Adjusting for anyone without a license is barred separately (Tex. Ins. Code 4102.051).
Texas also bans deductible deals. The state insurance department says waiving or covering a homeowner’s deductible is illegal for contractors, and so is a rebate or credit in that amount (TDI).
Florida ended assignment of benefits on new policies. For residential and commercial property policies issued on or after January 1, 2023, an attempt to assign post-loss benefits “is void, invalid, and unenforceable.” Policies issued from July 1, 2019 up to that date capped an emergency assignment at the greater of $3,000 or 1 percent of the Coverage A limit and gave the homeowner 14 days to rescind (Fla. Stat. 627.7152). In practice your contract is with the homeowner, who owes the bill and receives the insurer’s payment.
Maryland draws the line most clearly. A home improvement contractor may prepare a repair estimate and answer the insurer’s questions about it, but without a public adjuster license may not prepare the claim, negotiate it or advise on coverage (Maryland Home Improvement Commission).

Carriers and restorers commonly price losses in Xactimate, which Verisk describes as software “for sketching, scoping, localized pricing, and reporting” (Verisk). In our experience, a clean estimate backed by moisture maps and photos gets paid with fewer rounds of review.

Setting up the company

Entity and tax ID. The SBA notes that an LLC protects personal assets from business debts and lawsuits “in most instances” (SBA business structures). Form it with the state, then get a free EIN from the IRS.

Sales tax. In Texas, labor to “repair, remodel, or restore residential real property is not taxable,” while the full charge for restoring nonresidential property is (Texas Comptroller Publication 94-116). Other states differ, so ask yours before the first commercial job.

Insurance. Beyond the mold minimums in the table, Google’s Water damage services ads ask for general and professional liability. Many general liability policies exclude mold, so ask for mold coverage by name. From what we see, restorers also carry pollution liability, commercial auto and inland marine coverage for equipment left running in customers’ homes.

Workers’ compensation. The SBA lists workers’ comp among the coverage every business with employees must carry (SBA business insurance), and the states set the rules. California requires it “even if they have only one employee” (California DWC). Florida requires it from one employee in construction and four elsewhere (Fla. Stat. 440.02); rebuild work is plainly construction, and how pure drying is classed is a question for your carrier. “Texas doesn’t require most private employers to have workers’ compensation,” except on government contracts (TDI).

Crews. Calling a technician a subcontractor with “no reasonable basis for doing so” can leave you owing that worker’s employment taxes (IRS).

Drying equipment, trucks and a place to keep them

In our experience, a new restoration company buys these first:

Extraction and drying: a truck-mounted or portable extractor, low-grain refrigerant and desiccant dehumidifiers, air movers, and HEPA air scrubbers.
Measurement: moisture meters, thermo-hygrometers and a thermal camera. The readings become the adjuster’s drying log.
Mold and sewage gear: containment poly, zip doors, negative air machines, HEPA vacuums and protective gear. EPA’s remediation guide recommends disposable clothing on medium and large jobs, says respirators “must be in compliance with OSHA regulations,” and recommends a full-face powered air purifying respirator for heavy contamination (EPA mold remediation guide, chapter 3).
Vehicles: a box truck or van with shelving, and a trailer.
Software: an estimating platform, moisture mapping and drying logs, photo documentation, a CRM and job board, and answering that covers every hour of the night.
Space: a warehouse or yard where equipment can be cleaned, dried and stored. Texas mold companies must keep an office in the state.

Pricing, payment and the emergency waiver

No public source with a stated method gives restoration price levels or startup costs, so none appear here. The SBA startup cost checklist lists the categories; for a restorer the heavy ones are usually the drying fleet, the truck, insurance and the payroll you carry while claims are reviewed. Insurance jobs are estimated line by line, program jobs follow the program’s price list, and uninsured jobs are quoted per job or on time and materials.

The FTC Cooling-Off Rule lets a buyer cancel certain sales made at home within three business days, and the FTC says it does not cover sales “needed to meet an emergency” (FTC Cooling-Off Rule). The rule text is narrower: the exemption applies only when the buyer initiated the contact, the need is a “bona fide immediate personal emergency,” and the buyer gives you a separate, dated and signed statement “in the buyer’s handwriting” describing the emergency and waiving the right to cancel (16 CFR 429.0). A printed checkbox on a work authorization is not that statement.

Cash arrives late. Carriers pay after review, and program work often adds its own payment terms, so a new company floats labor and equipment wear for weeks. The SBA says a new business’s loan eligibility “is typically based on its owner’s personal credit score” (SBA).

Hiring technicians and keeping them safe

Technicians rarely arrive trained: O*NET places the proxy occupation in Job Zone 1 to 2, little to some preparation needed. Since WRT has no prerequisites and runs by live stream and in Spanish, in our experience a new hire can be certified within weeks. O*NET also points employers to Registered Apprenticeship, though no restoration-specific program could be confirmed.

OSHA has no mold-specific standard; its mold page points to sanitation rules and respiratory protection (OSHA mold standards). The standards that catch restorers are general ones:

Respirators. Respiratory protection was on OSHA’s list of most-cited standards for fiscal year 2025, and hazard communication was second (OSHA top 10). Respirator wearers need medical evaluations and fit testing (OSHA respiratory protection), and antimicrobials bring hazard communication training.
Falls. Fall protection led the same list and construction ladders came third, which matters for roof tarping after storms and for rebuild work.
Reporting. Employers must tell OSHA within 8 hours of a work-related death and within 24 hours of a severe injury (OSHA recordkeeping).

Finding the first customers

Google Business Profile. A rented address where the business does not operate “isn’t eligible for a Business Profile,” and a service-area business can list an office only if it is staffed during business hours (Google guidelines). Set up to 20 service areas, kept within about two hours’ drive of your base (Google service areas). Google chooses the verification method, and recommends video where it is offered (Google verification).

Local Services Ads. The Water damage services category lists general and professional liability insurance, state business and owner licenses where the law requires them, and “IICRC certification,” with a note that some states require extra licenses for mold work. Screening takes “3-4 weeks” on average after documents go in (Google requirements), and select accounts also get identity, criminal history and civil litigation checks (Google background checks). Fire and smoke work has no category of its own. These ads began moving into Google Ads in August 2026; water damage was not in the first group, and Google’s schedule widens to service-area businesses without storefronts late in 2026 (Google Ads migration).

Reviews. BrightLocal’s 2026 survey found 47 percent of consumers will not use a business with fewer than 20 reviews, and 74 percent only care about reviews from the last three months (BrightLocal). Ask when the equipment comes out, not weeks later. The FTC’s 2024 rule bans fake and bought reviews and lets the agency seek civil penalties against knowing violators.

Partners. Since the S500 leaves the source repair to the owner, the plumber at a burst pipe is usually first on site and a natural referral source. Property managers, HOA managers, insurance agents and independent adjusters send repeat losses.

When the company is ready for its first season, our page on marketing for restoration companies covers night call cover, claim-safe ad copy and how jobs arrive from each source. Google Business Profile setup and Google Ads and Local Services Ads are the two pieces to get right first.

What trips up new restoration companies

A phone nobody answers at night. EPA tells homeowners to dry wet areas within 24 to 48 hours (EPA), so the caller moves down the list.
One program for most of the work. In our experience, program volume can vanish with one contract change.
Claim language. “We handle your claim” crosses Texas law and Maryland’s public adjuster line.
A rebuild without a contractor license. Florida’s mold statute forbids it, and California’s line sits at $1,000.

Questions people ask before starting a restoration company

Do you need a license to start a water damage restoration company?

Not for water drying itself in Texas, Florida or California, as far as those states’ agencies show. Mold work needs a state license in Texas, Florida and New York, and rebuild work needs a contractor license where the state requires one, so check with your state and city.

Which IICRC certification should I get first?

Start with WRT, which has no prerequisites and an $80 exam as of October 2026. ASD and AMRT both require it, and MRS needs a year of verifiable mold remediation experience.

Can my company test for mold and then remove it?

Not on the same job in the states covered here. Texas forbids assessing and remediating the same project, New York forbids one individual doing both on a property, and Florida bars a remediator from assessing a structure its company remediated within 12 months.

What insurance does a restoration company need?

General liability with mold coverage at minimum: Florida sets $1,000,000 for remediators, Texas $1 million per occurrence for mold companies and New York $50,000. Google’s ads also ask for professional liability, and workers’ comp follows state rules.

Can I take an assignment of benefits in Florida?

Not on a residential or commercial property policy issued on or after January 1, 2023, where the statute makes an assignment void. Older policies issued from July 1, 2019 still allow one under limits.

Can a restoration contractor help a homeowner with the claim?

Yes, up to a point: you can estimate, document and answer the insurer’s questions about your estimate. Preparing or negotiating the claim belongs to licensed public adjusters, and in Texas a contractor may not adjust or advertise to adjust claims on its own jobs at all.

Does the three-day cancellation rule apply to emergency water jobs?

Yes, unless the homeowner waives it in writing. The FTC exemption needs a customer who called you, a real emergency and a handwritten, signed and dated statement waiving the right to cancel.
