Is it licensed here?

Is mold remediation licensed in New Jersey?

No. New Jersey does not license, register or certify mold remediation or mold inspection companies, and bills to create a state mold certification passed the Legislature in 2014 and 2020 but were never signed. Home improvement contractors must register with the Division of Consumer Affairs, but that registration is not a mold credential.

Whatever the state requires, a mold-specific certification from an industry body is worth asking for. Examples include the IICRC's course-based Applied Microbial Remediation Technician (AMRT) and its experience-based Mold Remediation Specialist (MRS), and the ACAC's Council-certified Microbial Remediator (CMR). Each requires an exam, and each can be checked with the body that issued it. These are held by individuals, not companies, so ask who on your job holds one.

Insurance is the other half. Ask for a certificate of insurance that names general liability coverage, and call the carrier on the certificate to confirm it is current. Then get the job in writing before anyone starts: what will be contained, what will be cleaned or removed, who will fix the moisture source, and how the finished work will be checked and documented.

Consumer Warning

New Jersey has no state license, registration or certification for mold remediation. This makes verification critical. Anyone can buy a truck and call themselves a "Mold Expert." Every listing here is identity-checked, and we show IICRC certifications and insurance only where a company has supplied them for verification, so you can see what has actually been checked before you call.

What to ask a mold company for in New Jersey

  • A mold-specific certification held by the person who will run your job (IICRC AMRT or MRS, or ACAC CMR), checked with the issuer, not just a general contractor registration
  • A certificate of insurance showing general liability, confirmed with the carrier
  • A written scope: containment, what gets cleaned or removed, and who will fix the moisture source
  • How the finished work will be checked and documented, with an independent check where the job calls for one
  • Recent reviews under the same business name and address that appear on the quote

What a typical job costs

What mold remediation costs in New Jersey

$1,223 – $3,757typical job, nationwide

Source: HomeAdvisor, 7,952 reported project costs, June 2026

We don't have a figure specific to New Jersey. This is the national range. A single contained problem, like one wall or a bathroom ceiling, often comes in under it; whole-basement or post-flood work runs over it. If you get an independent assessment before the work, which we recommend, it is priced separately from the remediation, and so is an independent check after it where the job calls for one. Both should be.

Size it to your own job

Two questions give the range for a job like yours, and where each number comes from.

How much
A small patch, one area or room, several areas, or throughout the home
Where
On a surface I can see, inside walls or under floors, or in the AC or ducts
Then
Your ZIP finds verified pros near you

What comes back: the remediation range with its source, the assessor's visit and a clearance test, which not every job needs, as their own lines, and a total.

Questions people ask

Common questions about mold remediation in New Jersey

Answered without a sales pitch.

  • How much does mold remediation cost in New Jersey?
    Nationally, a typical mold remediation job runs $1,223 to $3,757, from 7,952 project costs reported to HomeAdvisor. We don't have a figure specific to New Jersey. The price moves with how much material has to come out, whether the moisture source is fixed in the same job, and whether containment and air filtration are needed. Get the scope in writing and ask how the finished work will be checked. If an independent check after the work is planned, ask what it will cost, because it is priced separately from the remediation.
  • Does New Jersey require a license to do mold remediation?
    No. New Jersey does not license, register or certify mold remediation or mold inspection companies, and bills to create a state mold certification passed the Legislature in 2014 and 2020 but were never signed. Home improvement contractors must register with the Division of Consumer Affairs, but that registration is not a mold credential. Whatever the state requires, a mold-specific industry certification is worth asking for, such as IICRC AMRT or MRS, or ACAC CMR, each of which you can check with the body that issued it.
  • Can you sell a house with mold in New Jersey?
    Selling is legal. What gets sellers in trouble is hiding a problem they knew about: in most states a known mold or water problem is a material defect that has to be disclosed, and a buyer's inspector tends to find it anyway. The two clean routes are to remediate before listing and keep the records that document the finished work, including any verification report, or to disclose it and price the work in.
  • How do I check a mold company in New Jersey?
    Ask for three things and check each one yourself: a mold certification held by the person who will run your job, which you can find on the IICRC or ACAC public register, a certificate of insurance you confirm with the carrier, and a written scope of work. Then look the business up under the exact name and address on the quote. Our listings show which of those checks we could complete for each company.
  • Is a free mold inspection a red flag?
    Not on its own, but know what it is. A remediator inspecting your home before it quotes is normal, and a free visit is a fair way to get an estimate. It is not an independent assessment, though: a company that also sells remediation has a potential financial stake in what it finds. Our recommendation is to pay for an assessment from a company that will not do the remediation, which takes that incentive out of the diagnosis, and to have an independent check of the finished work where the job calls for one. That holds with or without a state license behind it.
  • What can renters in New Jersey do about mold?
    Report the moisture problem to the landlord in writing, with photos and dates, and ask for the leak or ventilation fault to be fixed rather than the stain painted over. If nothing happens, the local building or code enforcement office can inspect for the underlying water problem even where there is no mold rule to enforce. Keep every message; a tenant remedy or a health complaint will rest on that record.
