What to do when you find mold
Mold grows where water stayed. Finding the moisture source matters more than killing what's visible.
- Don't scrub, sand or dry-brush large patches. It sends spores into the air.
- Don't paint over it or spray bleach on drywall; the growth on the back of the wall stays.
- Fix or stop the leak if it's still active.
- Keep the room closed and turn off forced air if the vents are in that room.
- Photograph the area and note when the original water damage happened.
Then send the form below or call (385) 346-0996. If anyone in the house has breathing problems, headaches or allergy symptoms that get worse at home, see a doctor.
How mold remediation is typically done
Most companies follow the IICRC S520 standard. Ask the one you choose how its plan lines up with it.
Assess and find the water
A moisture meter and a visual inspection show how far the growth goes and what's still wet. Some homeowners hire a separate inspector for testing.
Contain the work area
Plastic barriers and negative air pressure keep spores from spreading to clean rooms while work is underway.
Remove affected materials
Moldy drywall, insulation and carpet are bagged and removed. Framing is cleaned, often sanded or treated.
HEPA clean and dry
HEPA vacuums and air scrubbers clean the area, and drying equipment brings materials to normal moisture levels.
Verify, then rebuild
A final check or clearance test confirms the area is clean before a DOPL-licensed contractor closes the walls.
Mold in Utah Valley homes
Utah's dry climate slows mold in most of the house. Basements are the exception. They stay cool, concrete holds moisture, and finished walls hide the back of the drywall where growth starts. Most mold calls here trace back to a water event that wasn't dried completely: a window well that leaked in a storm, a slow drip from a water heater, or spring groundwater seeping in along the base of a wall.
Timing matters. Mold can begin growing within 24 to 48 hours on wet drywall, carpet pad and wood, which is why prompt extraction and drying after any leak is the best prevention.
Licensing in Utah
Utah doesn't appear to have a mold-specific license. Ask about IICRC training, and use a DOPL-licensed contractor for any rebuild. Removing drywall and rebuilding walls is construction trade work, and you can check any contractor's license at dopl.utah.gov.
Older homes
About 37% of Orem homes and 46% of Provo homes were built before 1980. Before moldy drywall or textured ceilings come out of an older home, ask whether an asbestos test is needed. Homes built before 1978 also need lead-safe certified renovators for work that disturbs painted surfaces, under Utah's DAQ lead program.

Does insurance pay for mold?
Many homeowners policies cap or exclude mold, especially when it comes from a long-term leak or humidity. Some cover mold that results directly from a covered sudden water loss, often with a lower limit. Check your policy for a mold or fungi section and ask your adjuster.
This is one reason fast action matters: an insurer may treat mold that grew because water wasn't addressed as a maintenance issue. Keep dated photos and receipts from the original leak. Utah's claims rule (R590-190) generally requires insurers to accept or deny within 30 days of a complete proof of loss, or explain why they need more time.
When mold needs attention now
- The growth covers more than about 10 square feet, or it's spreading.
- It followed a sewage backup or floodwater.
- Someone in the house has asthma, a weakened immune system or new symptoms.
- The musty smell is strong but you can't see the source, which suggests growth inside walls.
- You're about to sell or rent the home.
Mold after water damage FAQ
How fast does mold grow after water damage?
Mold can start growing on wet drywall, carpet pad and wood within 24 to 48 hours, and becomes visible within days. That's why drying a wet basement promptly matters. Growth on the back of drywall or under carpet may not show for weeks, so a lingering musty smell after a leak is worth checking.
Can I remove mold myself?
Small patches on hard surfaces, roughly under 10 square feet, can often be cleaned with detergent and water while wearing gloves and a mask. Larger areas, mold inside walls, or mold after sewage or floodwater are better handled by a professional with containment and HEPA equipment. Fix the moisture source either way.
Does Utah require a mold license?
Utah doesn't appear to have a mold-specific license. Ask companies about IICRC training and whether they follow the S520 standard. Any rebuild after removal, such as new drywall, is construction work, so use a contractor licensed by Utah DOPL and verify the license at dopl.utah.gov.
Is mold after a leak dangerous?
Mold can trigger allergy symptoms, asthma attacks and irritation, and people with weak immune systems are at higher risk. Keep people out of the affected room, avoid disturbing the growth, and see a doctor if anyone has symptoms that seem linked to the home.
