Short answer

Utah does not license mold remediation specifically, but a contractor license from the Utah Division of Professional Licensing (DOPL) is generally required for construction work valued at $7,000 or more. Ask for proof of liability insurance, a written scope that follows the IICRC S520 standard, and a plan for the moisture source.

Utah Licensing Basics

Utah licensing basics for mold and repair work (2026)Summary of Utah Code §58-55-305 as amended by HB 483 (2024). Confirm current rules with DOPL.
SituationWhat applies
Mold remediation as a specialtyNo separate state mold license in Utah
Work under $3,000Generally exempt from contractor licensing
Work $3,000 – under $7,000Exempt only with a DOPL affirmation of exemption and liability insurance
Work $7,000 or moreLicensed contractor required
Electrical, plumbing, HVAC workAlways requires the appropriate trade license

You can look up any contractor license on the DOPL website.

Vet a Company in About an Hour

  1. Look up the licenseSearch the company name on the DOPL license lookup. For jobs of $7,000 or more, the license should be active and in the company name on the bid.
  2. Ask for an insurance certificateHave the insurer send a certificate of liability insurance directly to you, not a photo of one.
  3. Check the addressA real local business has a real address and answers the phone with its own name.
  4. Check trainingIICRC keeps a public locator of certified firms; AMRT training means the crew learned the S520 standard.
  5. Read recent reviewsLook for comments about containment, cleanup and how surprises were handled, not just friendliness.

Questions to Ask Every Company

  1. What caused the mold, and how will it be fixed?A good answer names the water source and the repair.
  2. What containment will you use?Look for poly barriers and negative air pressure with HEPA air scrubbers for anything beyond a small patch.
  3. Exactly what will you remove and clean?Square footage by material, in writing.
  4. How do you confirm the job is done?Visual check, moisture readings, and optional independent clearance testing.
  5. What happens if you find more mold?A written change-order process before extra work starts.
  6. Can I see proof of insurance and any certifications?Liability insurance at minimum; IICRC training such as AMRT is a plus.

Ask whether testing is done by a separate firm; see why independent mold inspection protects you.

Red Flags

  • "Fogging only" or spray-only treatment of mold inside walls, with no removal.
  • Scare tactics about "toxic black mold" to rush a decision.
  • A company that tests, then insists on a huge remediation without showing results.
  • No written scope or a single lump-sum price with no detail.
  • Cash-only, large upfront deposits or pressure to sign today.
  • No plan for the moisture source.

Check each bid against the typical Eagle Mountain mold removal costs.

What a Real Scope Looks Like

A written scope should let a second contractor price the exact same job. If you cannot tell from the paper what is being removed and how, it is not a scope.

Example scope lines for a basement bedroom wall
LineExample
ContainmentPoly walls and zipper door around the bedroom; HEPA air scrubber exhausting outside; HVAC vents sealed
RemovalDrywall and insulation on the north wall from the floor to 4 ft (about 60 sq ft); carpet and pad in the room
CleaningHEPA vacuum and damp-wipe framing, slab and containment; sand stained bottom plate
DryingDehumidifier until framing matches dry readings elsewhere in the house
VerificationVisual inspection and moisture readings; optional independent clearance test
Not includedWindow well drain repair, new drywall, paint and carpet (quoted separately)

Contract and Payment Terms

  • A reasonable deposit, with most of the payment due after the work passes the final check.
  • A written change-order process: no extra work or cost without your signature.
  • Who fixes the water source, and whether that is in this contract.
  • What the warranty covers. Be wary of "mold-free forever" promises; a fair warranty covers the workmanship, as long as the moisture stays fixed.
  • The documents you get at the end: photos, moisture readings and any lab reports.

If you want an outside check of the result, decide up front who should run the clearance test.

How to Compare Bids

  • Line up the same items: containment, square feet removed, HEPA cleaning, drying, verification, rebuild.
  • Ask each company to price the same scope if their scopes differ widely.
  • Check how each handles hidden mold and change orders.
  • Prefer the clearest written plan over the lowest number.

Frequently Asked Questions

Do mold remediation companies need a license in Utah?

Utah has no specific mold remediation license. A DOPL contractor license is generally required for construction work valued at $7,000 or more, and trade work needs trade licenses.

What certifications should a mold company have?

There is no required certification in Utah. IICRC training such as AMRT (Applied Microbial Remediation Technician) shows the crew learned the industry standard.

How much deposit should a mold remediation company ask for?

A reasonable deposit to schedule the work, with most of the payment due after the job passes the final check. Be wary of large upfront payments or cash-only terms.

Should the same company test and remediate?

It is common, but many homeowners prefer independent testing to avoid a conflict of interest, especially for clearance.
