Should You Hire a Mold Company That Also Does Remediation?

You can, and plenty of them do careful work. But you should understand what you are buying. When one company decides whether you have a mold problem and also sells you the cleanup, the person answering the question is paid more if the answer is yes. That is not an accusation against anyone. It is the structure of the transaction.

The safest arrangement is simple. Have the assessment done by someone who cannot bid the remediation, then take that report to remediation contractors and let them compete on the same defined scope. If you only remember one thing from this page, remember that separating the diagnosis from the cure costs a few hundred dollars and protects a job that often runs into five figures.

The rest of this page explains the incentive honestly, what Washington and Idaho actually regulate, why one state banned the combined arrangement outright, when hiring a combined company is perfectly reasonable, and the specific questions to ask any company you call. Including us.

How the incentive actually works

Nobody in this industry wakes up planning to invent mold. The problem is subtler and more human than that, and it shows up in three places.

The judgment calls. Mold assessment is full of them. Is that staining active growth or an old, dried, resolved event? Does the elevated Aspergillus and Penicillium count in the basement warrant containment and demolition, or a dehumidifier and a recheck in six weeks? Is the affected area two square feet or twelve? Reasonable professionals disagree on these. If one answer produces a $9,000 contract and the other produces a handshake, the ambiguity does not resolve neutrally. It does not require dishonesty. It requires only that a person be a person.

The free inspection. Free and near-free inspections are common in this market, and they are not charity. The visit is a customer acquisition cost, recovered on the back end when the cleanup gets sold. If the visit finds nothing, the company loses money on it. A business model that loses money whenever the news is good is worth understanding before you invite it into your crawlspace.

Scope. Even when mold is genuinely present, the size of the job is a negotiation between what is necessary and what is billable. The IICRC S520 standard, which is the industry reference for professional remediation, describes conditions and general principles. It does not hand anyone a square footage number. Somebody has to write the scope, and if that somebody is also bidding it, you have no second opinion in the process.

And the clearance test at the end. This is the part homeowners miss. After remediation, someone should verify the work with post remediation verification: a visual check of the containment and the remediated area, air samples inside containment plus an outdoor control, judged against the standard. When the remediator performs their own clearance, the exam is being graded by the student. A failed clearance means going back in at their own cost. Guess how often self-administered clearances fail.

What Washington and Idaho actually require

Very little, and this is the most important fact on the page.

The Washington State Department of Health states plainly that there are no certification requirements for mold assessment or remediation in Washington, and that anyone can call themselves a mold specialist without any training or credentials. Idaho is the same. Idaho licenses neither mold work nor home inspection.

So the letters after somebody's name on a business card are voluntary. They may reflect real training, and often do. But no state agency issued them, no state agency can revoke them, and nothing prevents a company from doing both the assessment and the remediation on the same house on the same day.

Compare that to New York. Under New York Labor Law Article 32, it is illegal for the same company to perform both the mold assessment and the mold remediation on the same job. The assessor writes a remediation plan, a separate licensed remediator performs the work, and a separate clearance follows. New York looked at this exact incentive structure and decided homeowners could not be expected to police it themselves.

Washington and Idaho drew no such line. That does not make combined companies here bad actors. It makes the independence something you have to choose rather than something the state guarantees.

There is a related quirk worth knowing. Washington's home inspection rules, WAC 308-408C-030, specifically exclude environmental hazards including mold from the standards of practice, and WAC 308-408C-050 requires every pre-inspection contract to state that the inspection does not investigate mold unless separately agreed in writing. That is why your home inspector points at a stain and tells you to call someone else. They are required to.

When hiring a combined company is fine

This page is not an argument that you must always hire two companies. Sometimes that is a waste of your money, and we will tell you so on the phone.

You can already see it and you already know why it is wet. A supply line let go under the kitchen sink, the cabinet base is soaked, and there is growth on the back of the cabinet. You do not need a lab to tell you that. S520 does not prescribe a different remediation protocol based on species. Call a restoration company and get it dried and cleaned.

It is small and obvious. Surface growth on bathroom grout or a windowsill is a ventilation and cleaning issue. Testing it is a purchase, not a decision.

Emergency response. After a burst pipe at 11pm, you want water extraction and drying equipment in the house tonight, not a testing appointment. Get the water out first. Documentation and verification can follow.

The combined model gets risky specifically when the answer is genuinely uncertain, when the proposed scope is large, or when someone else is going to rely on the result. That means insurance claims, real estate transactions, landlord and tenant disputes, and any project where the quote made you pause.

Questions to ask any company you call

Ask these of every company on your list. Ask them of us.

If you ask us the first one, the answer is no. We test only. We do not perform remediation, we do not take referral fees from remediation companies, and we have no financial interest in what the samples show. That is why our inspection is $425 with lab samples included rather than free. The work has to pay for itself, because there is no back end.

We will also hand you a list of remediation contractors if you want one, with no arrangement behind it, and we are happy to be told you went with someone else's.

What independence does not mean

It does not mean we are more accurate than a good remediation company's assessor. Some of them are excellent, and the equipment is the same: calibrated pumps drawing a measured volume through spore trap cassettes, moisture meters, thermal imaging, a borescope for wall cavities.

It means we have no reason to prefer one interpretation over another. When a homeowner in a 1948 Spokane house with a stained crawlspace joist asks whether this needs a $14,000 encapsulation project, our answer costs us nothing either way. Sometimes it is yes. Frequently it is that the vapor barrier failed, the wood is dry now, and the fix is plastic and a fan.

Frequently asked questions

Is it actually illegal anywhere? Yes. New York Labor Law Article 32 prohibits the same firm from assessing and remediating the same project. Washington and Idaho have no equivalent rule.

Are combined companies unlicensed then? There is no mold license in either state to hold or lack. Contractors doing construction work carry a contractor registration and should carry liability insurance, but neither state issues a mold assessment credential at all.

Should I get the assessment before or after the remediation quote? Before. A report that defines the affected areas, moisture conditions, and a scope lets multiple contractors bid the same job. Without it, every bid describes a different project and you cannot compare them.

My remediation company offered a free clearance test. Should I take it? Take a clearance test, but not from them. A passing grade from the party being graded is not verification. Independent clearance is $375 flat for up to three samples, which is small against the cost of finding out next spring that it was not finished.

Do you take money from restoration companies for referrals? No. Not a fee, not a percentage, not a reciprocal arrangement. We also perform clearance testing for restoration partners at $375, and those companies know that a failed clearance is a real possibility. That is the point of hiring us.

Does hiring you mean I will be told I have mold? Not remotely. A meaningful share of our inspections conclude that indoor spore counts are normal relative to outdoors and no remediation is warranted. That is a complete, useful, and common result.

Book an assessment with nothing riding on the answer

Tell us what you are seeing, what you smell, and whether an insurer, a buyer, or a landlord is involved. You will get a firm price, an appointment, and a report written by someone who does not profit from what it says. If we think testing will not change anything for you, we will tell you that before you book.
