Is it licensed here?

Does the District of Columbia license mold remediation?

Yes. In the District of Columbia, if you pay someone to assess or remediate 10 square feet or more of mold in one area of a home, the work must be done by, or under the supervision of, a professional licensed by the Department of Energy & Environment (DOEE), and DOEE publishes a list of licensed mold professionals you can check before you hire. A listing here shows a license only when we have one on file for it. Any DC license we show comes from DOEE's public list of licensed mold professionals, which doesn't publish license numbers or expiration dates.

In DC the license belongs to a person, not the company. Whatever the size of the job, a company may call itself licensed there only if it employs a licensed professional, or is one working under their own name. The license tells you that person passed a DOEE-approved exam and met DOEE's education, experience, and insurance requirements, or holds a mold license from another state that DOEE approves. It does not tell you how good the work is or whether that insurance is still current, so the credential check is where the vetting starts, not where it ends. Insurance you confirm with the carrier, a written scope, and, where the job calls for one, an independent check of the result still matter.

District Licensing

The District of Columbia licenses mold work through the Department of Energy & Environment (DOEE), and only individuals hold the license, not companies. The District publishes a list of license holders by name, so ask who holds the license and will run or supervise your job, and find that person on the list before you hire.

What to ask a mold company for in the District of Columbia

  • The name of the licensed professional running the job, found on the DOEE list before you sign
  • 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

We don't have a figure specific to Washington DC. 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 District of Columbia

Answered without a sales pitch.

  • How much does mold remediation cost in the District of Columbia?
    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 Washington DC. 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 the District of Columbia require a license to do mold remediation?
    Yes. In the District of Columbia, if you pay someone to assess or remediate 10 square feet or more of mold in one area of a home, the work must be done by, or under the supervision of, a professional licensed by the Department of Energy & Environment (DOEE), and DOEE publishes a list of licensed mold professionals. In DC the license belongs to a person, not the company. Whatever the size of the job, a company may call itself licensed there only if it employs a licensed professional, or is one working under their own name. The list shows names, not license numbers, so ask who holds the license and will run or supervise your job, and find that person on the list before you sign.
  • Can you sell a house with mold in the District of Columbia?
    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 the District of Columbia?
    Start with the DOEE list of licensed mold professionals: find the person who will run your job. Then ask for a certificate of insurance you confirm with the carrier and a written scope of work, and 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 the District of Columbia 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.
