Most Plumbers in a Water Loss Are Not Your Friend
When your pipe bursts and water is spreading across your floor, the plumber who arrives to fix the leak feels like a lifeline. You trust them. You are grateful they came. And when they pull out their phone and say “let me call a restoration company I know — they’ll take good care of you” — it feels like they are going above and beyond to help. They are not. In almost every case in this industry, they are making a call that earns them a significant amount of cash. The recommendation has nothing to do with you.
I spent over a decade as a licensed property insurance adjuster handling claims for major carriers and as the owner of a water mitigation and restoration company. I have seen this system operate from every angle — as the adjuster reviewing inflated invoices, as the contractor who understood how the referral game worked, and now as the founder of DeniedClaims.net, giving homeowners the information they deserve to have.
Let Me Be Direct: This Is an Industry-Wide Practice
I am not going to soften this. What I am about to describe is not a bad apple situation. It is not a few unethical companies taking advantage of an otherwise clean system. The kickback referral arrangement between plumbers and water mitigation companies is standard operating procedure across the water damage restoration industry in most markets across the United States.
If you had a water loss and a plumber recommended a restoration company — there is an overwhelming likelihood that a cash payment changed hands in connection with that recommendation. Not because the plumber thought the company was the best. Not because they had vetted the company’s ethics, their IICRC certifications, their billing practices, or their history of treating homeowners fairly. Because that company pays the most.
That is the only selection criterion that matters in this system. Whoever pays the highest referral fee gets the job. The homeowner — whose house just flooded, who is in crisis, who is trusting the person who fixed their pipe — gets whoever won the bidding war. And they never find out.
How the Kickback System Actually Operates
The mechanics of this arrangement are not complicated. They operate the same way in market after market, with minor variations in how the payment is structured and how much changes hands.
💰 Follow the Money — Who Gets Paid and When
The mitigation company’s sales rep visits the plumber
Every significant water mitigation company has people whose entire job is maintaining relationships with plumbers, property managers, and other trade professionals who are first on scene after a water loss. They visit regularly. They bring lunch. They leave behind gift cards, cash, and referral fee agreements. The pitch is simple: send us your water jobs and we will pay you for every one.
Sales rep’s entire job = buying referralsThe plumber agrees to an exclusive or preferred referral arrangement
Most arrangements are informal — a handshake understanding that the plumber calls this company when a water loss job comes in. Some are more formal, with agreed-upon fee schedules. The plumber may have arrangements with two or three companies and calls whoever is currently paying the most. In competitive markets, mitigation companies actively outbid each other for plumber loyalty by raising their referral fees.
Referral fee: $500–$2,000+ per job deliveredYou experience a water loss — the plumber arrives
You call a plumber to fix the problem. They fix the leak. They are helpful, professional, and competent at their actual job. Then — almost as an afterthought — they make the call. “I know a great restoration company. I’ve worked with them for years. They’ll take good care of you.” You have no reason to doubt this. Why would your plumber recommend someone bad?
You have no idea a transaction is about to occurThe mitigation company arrives — under financial pressure from the start
The company that just paid $500 to $2,000 to acquire your job has a cost structure that requires them to recover that referral fee before they begin generating profit. The financial pressure to maximize the scope — place more equipment, run it longer, tear out more material, bill more hours — begins the moment they walk through your door.
Every inflated line item recovers the kickback they paidThe invoice arrives — you fund the entire chain
The final invoice reflects not just the cost of the work performed but the embedded cost of the referral fee, the sales operation that maintains plumber relationships, and the markup required to profit after all of those acquisition costs are recovered. You — the homeowner — fund every dollar of it. Whether through your insurance claim or out of your own pocket when the claim is denied.
You pay for the kickback that was never disclosed to youEveryone Is In On It — And Everyone Stays Quiet
One of the most striking things about the kickback referral system is how many people know about it and how completely it goes undisclosed to the one person it most affects — the homeowner. This is not a conspiracy in any dramatic sense. It is simply a financial arrangement that benefits everyone involved in the transaction except the customer, and so everyone involved has an incentive to keep it quiet.
Receives $500 to $2,000 or more in cash per job referred. Has no obligation under most state laws to disclose this payment to the homeowner. Their professional reputation for plumbing work is entirely separate from the quality of the company they are referring — they face no accountability for what happens after the mitigation crew arrives.
Pays the referral fee as a standard cost of customer acquisition. Recovers it through the invoice. Has a direct financial incentive to maximize scope on every referred job. Benefits from the plumber’s trust relationship with the homeowner — that trust is borrowed and leveraged without the plumber ever having evaluated the company’s actual billing practices.
The technicians who arrive at your door are often unaware of the specific referral arrangement — or if they are aware, it is simply accepted as how business development works in their industry. They do the job they are assigned. The scope decisions that drive overbilling typically come from management and estimating, not from the crew on the floor.
Trade associations, restoration industry conferences, and contractor networks are generally aware that referral arrangements are pervasive. Some have attempted to establish ethical guidelines around disclosure. Those guidelines are largely ignored in practice because the financial incentives to maintain the system are far stronger than any reputational incentive to disclose it.
The plumber who recommended a mitigation company to you has almost certainly never reviewed that company’s Xactimate estimates. They have never spoken to a homeowner whose claim was denied after that company performed the work. They have never evaluated whether that company’s billing practices comply with the IICRC S500 Standard. They have spoken to that company’s sales representative — the one who offered the best referral fee. That is the entire basis of the recommendation you received.
The Referral Is Not Based on Quality. Period.
This point deserves its own section because it is the one that homeowners find most difficult to accept. The plumber seemed trustworthy. They did good work on the actual plumbing problem. Why would they recommend someone bad?
The answer is that the recommendation is not a quality assessment — it is a financial transaction. And the two things have nothing to do with each other.
They did not review Google ratings, check IICRC certifications, look at complaint histories with the state licensing board, or ask former customers whether the billing was fair. They called whoever is currently paying them the most.
Once the mitigation crew is in your home and the plumber drives away, the plumber has zero involvement in what follows. They do not know what the crew bills. They do not know whether the equipment count matches the invoice. They do not know whether dry standard was reached on Day 4 but equipment was billed through Day 12. They are not accountable for any of it.
You trust the plumber because they fixed your pipe competently and professionally. That trust is real and it is earned. But the mitigation company is borrowing that trust through the referral — and they did not earn it. A plumber with an excellent reputation for plumbing work can refer a mitigation company with a history of overbilling and disputed invoices without any contradiction in their own professional conduct.
When a plumber says they have worked with a mitigation company for years and they have always been great — what they are describing is a financial relationship that has been consistently rewarded. A long-standing referral arrangement means the mitigation company has been reliably paying the referral fee. It says nothing about how they treat homeowners or how accurately they bill.
“You need to act fast — mold sets in within 24 hours.” This statement, true in its general form, is used as a closing tool to prevent you from taking the time to find your own contractor, get a second opinion, or call your insurance company first. The urgency benefits the company that needs you to sign a work authorization immediately. It does not benefit you.
What the Industry Knows and Won’t Tell You
Within the water damage restoration industry, the referral kickback system is not a secret. It is discussed openly at trade conferences, negotiated between sales teams and plumbing companies, and treated as a standard cost of doing business. Contractors who refuse to participate in referral fee arrangements — and some reputable companies do refuse on principle — consistently find themselves excluded from the informal referral networks that drive a significant portion of residential water loss work.
The market dynamic this creates is genuinely troubling: companies that prioritize honest billing and refuse to pay kickbacks lose jobs to companies that are willing to pay and inflate invoices to recover the cost. Over time the system selects for exactly the wrong type of contractor and against exactly the right type — and homeowners bear the entire cost of this selection effect without knowing it exists.
“In the markets I worked in, plumbers who were not receiving referral fees were the exception — not the rule. The question was never whether a plumber was receiving a kickback. The question was how much and from whom.”— Patrick Watson, Licensed Property Insurance Adjuster & Former Mitigation Contractor Owner, DeniedClaims.net
How the Kickback Inflates Your Invoice
The referral fee does not appear as a line item on your invoice. You will never see “Plumber referral fee: $1,000” in your Xactimate estimate. But the cost is there — embedded in the invoice through the mechanisms that every mitigation contractor understands.
A company that paid $1,000 to acquire your job and operates at a 20 percent net margin needs to generate $5,000 in gross revenue before it nets a single dollar of profit from your job. That financial reality creates a structural incentive — not a decision that gets made consciously on each job but a systemic pressure that runs through every scope decision, every equipment placement, every day of drying time billed.
- Equipment is placed in quantities slightly above what the loss genuinely requires — air movers billed at 6 when 4 are present
- Equipment runs longer than the moisture data justifies — billed through Day 12 when dry standard was confirmed on Day 4
- Demolition scope is expanded beyond what pre-removal moisture readings support — removing adjacent dry materials along with the genuinely wet ones
- Labor hours are billed slightly above what crew logs would confirm — adding hours to visits that the plumber’s call made possible
- Overhead and profit is calculated on a subtotal already inflated by all of the above — compounding every inflated line item by an additional 20 percent
None of these items individually screams fraud. Taken together, across a job that cost $1,000 to acquire and that needs to generate $5,000 in gross revenue before profit begins, they add up to exactly the kind of invoice that DeniedClaims.net exists to help homeowners challenge.

Is the Kickback Arrangement Legal?
The legal landscape around referral fees in the insurance and contracting context is complex and varies significantly by state — but the arrangement sits in murky territory that most participants prefer not to examine too closely.
The Federal Trade Commission’s Endorsement Guides establish clearly that any material connection between an endorser and a recommended business must be disclosed. A cash payment is unambiguously a material connection. That disclosure almost never happens.
Several states — Florida most prominently — have enacted legislation specifically targeting kickback arrangements in the property damage restoration context. Florida’s Assignment of Benefits reform legislation addressed related abuses, and the state has pursued enforcement actions against contractors and referral networks engaged in the most egregious forms of this scheme.
Many states’ contractor licensing regulations include provisions prohibiting unlicensed fee-splitting or undisclosed referral arrangements in the insurance context. Whether these provisions are actively enforced is another matter — but they provide legal grounding for licensing board complaints when the practice can be documented.
The National Association of Insurance Commissioners (NAIC) has documented the connection between contractor referral arrangements and inflated insurance claims, noting that the practice contributes to rising premiums across the industry as carriers incorporate the cost of inflated mitigation claims into their rate-setting.
The kickback system and Assignment of Benefits (AOB) fraud are closely related. In states where AOB arrangements were prevalent, mitigation companies routinely combined kickback-generated leads with AOB documents that transferred homeowners’ insurance claim rights directly to the contractor. The contractor then inflated the claim, the insurer paid far more than the legitimate scope warranted, and everyone in the chain profited — except the insurer and eventually the homeowners who paid rising premiums. This is why Florida and other states moved aggressively to reform AOB laws.
What You Need to Do Right Now
If a plumber has already referred a mitigation company and work is underway or complete — you are not without options. Here is exactly what to do.
Contact the mitigation company directly and ask in writing: “Does your company pay a referral fee or any form of compensation to the plumber who referred this job?” Their response — or their discomfort with the question — is information. Document it.
If you have not already signed an AOB, do not sign one regardless of what the contractor tells you. An AOB transfers your insurance claim rights to them — they can negotiate and settle your claim without your involvement. A standard work authorization is sufficient to authorize the work. For more on AOB risks, see our article on questions to ask before signing a work authorization.
Start a written log today if you have not already. Record every crew visit with arrival and departure times, the number of technicians on site, and every piece of equipment you can count and photograph. Take dated photographs of all equipment daily. Ask for moisture readings at every monitoring visit and record the numbers. This documentation is your protection when the invoice arrives.
If demolition has not yet begun or is about to be expanded, call your carrier’s claims line immediately. Get a claim number. Ask what documentation they need before demolition proceeds. Some carriers require adjuster inspection before materials are removed. An inspection before demolition protects both you and the legitimacy of any future dispute about whether the scope was warranted.
When the invoice arrives, do not pay it immediately regardless of pressure from the contractor or collector. Review every line item against your independent documentation — crew log, equipment photographs, moisture readings. For a complete guide to what to look for and how to dispute what you should not owe, visit DeniedClaims.net.
If you need mitigation work and no company has been referred yet — find one yourself. Verify IICRC certification at iicrc.org. Verify their contractor’s license at your state licensing board. Read reviews on Google and the Better Business Bureau. Ask specifically: “Do you pay referral fees to plumbers or other trade professionals?” A company that does not participate in kickback arrangements will tell you plainly. A company that does will change the subject.
The Questions That Change Everything
You cannot undo a referral that has already happened. But you can ask the questions that reveal the financial relationship behind it — and the answers you get, or do not get, will tell you exactly how much independent scrutiny the rest of the engagement deserves.
“Do you receive any payment, referral fee, gift, or other compensation from the restoration company you just called?”
Ask this plainly, in front of any witnesses available. Their answer — or their avoidance of a direct answer — is one of the most useful data points you can gather in the first hour of a water loss.“Did you pay a referral fee or any form of compensation to the plumber who referred this job, and if so, how much?”
You are entitled to this information. It affects the financial structure of the engagement and your assessment of the scope decisions they will make. An honest contractor will answer directly.“What moisture reading, taken from this specific material before removal, shows that in-place drying was not feasible and supports the decision to remove it?”
Per the IICRC S500 Standard, demolition decisions must be data-driven. If they cannot produce a specific moisture reading that justifies removal, that removal may not be warranted — and the associated charges may be disputable.Already dealing with an invoice that looks inflated?
DeniedClaims.net provides homeowners with the exact tools to review their Xactimate estimate, identify overbilling, and dispute what they should not owe — including five ready-to-send dispute letter templates.
Visit DeniedClaims.net →Your plumber is a skilled trade professional who fixed your leak. That competence is real and you should be grateful for it. But the moment they made a phone call on your behalf, they shifted from tradesperson to commissioned referral agent — and the company on the other end of that call paid for the privilege of walking through your door. Knowing this does not make you cynical. It makes you informed. And in a water loss situation, informed homeowners protect themselves from the financial consequences that uninformed homeowners absorb every day.
Free resources to document your claim and challenge inflated invoices are available at DeniedClaims.net.
