A burst line or a roof leak in a Kona storm can soak a Maui home. We extract the standing water, set up dehumidifiers and air movers, and take moisture readings every day until the floors and framing test dry.

Mold help
Mold in Maui homes
Maui’s weather changes with elevation and wind. Upcountry towns like Kula and Makawao sit in cool, misty air much of the year. The windward side gets frequent trade-wind showers, so homes there stay damp for long stretches.
Many older Maui homes use board-and-batten or single-wall construction with little between the inside and the outdoors. Moisture reaches interior surfaces directly, and mold grows in closets, behind furniture, and on ceilings.
On the drier leeward side, condos and vacation rentals face a different problem. When the AC is off between guests, humid ocean air condenses inside and feeds mold on walls, mattresses, and cabinets.
Homeowners, property managers, and business owners across Kahului, Wailuku, Kihei, Lahaina, Paia, Makawao, Kula, Pukalani, Haiku, and Wailea call us about mold all year round.

Found mold?
What to do when you find mold
Finding mold is stressful, but you have time to do this right. Acting in the first day or two keeps it from spreading.
Not sure how big the problem is? Call and talk it through with our crew.
Call (833) 243-5663What to do
Look for the water
Check above and around the mold for a drip, a damp spot, or a stain. Stopping the water stops the mold from growing.
Bring the humidity down
Run the air conditioning or a dehumidifier. The EPA recommends keeping indoor humidity below 60%, ideally between 30% and 50%.
Take photos
Photograph the mold and any water damage before anything is cleaned. Your insurance company may ask for them.
Clean small spots the right way
For a patch under about 10 square feet, the EPA says you can usually clean it yourself with detergent and water. Wear gloves, eye protection, and a mask.
Keep sensitive people away
Anyone with asthma, allergies, or a weak immune system should stay out of the area until the mold is gone.
What not to do
Don’t scrub or sand it dry
Dry mold sends spores into the air and through the house. Keep the surface damp while you clean it, or leave it for a pro.
Don’t bleach it and paint over it
Bleach can whiten the surface, but on drywall and wood it doesn’t reach the mold growing inside. Paint over mold peels, and the mold keeps growing underneath.
Don’t point fans at it
Fans blowing across mold carry the spores into other rooms.
Don’t run the heat or air if the mold is in the ducts
The system will blow spores through the whole house. Leave it off until it’s been checked.
Don’t buy a test kit first
If you can see mold, the EPA says testing usually isn’t needed. Spend the money on finding the leak.
Where mold hides
Where we find mold in Maui homes
On Maui, mold usually comes from Upcountry dampness, windward rain, or humidity in closed-up leeward homes.
Upcountry Closets and Walls
Cool, misty air in Kula and Makawao keeps closets and outside walls damp.
Roofs and Ceilings
Trade-wind showers and Kona storms find gaps in metal roofs and soak ceiling boards.
Bathrooms and Kitchens
Steam and slow leaks grow mold quickly in humid air.
Condos With the AC Off
Leeward condos closed up between guests trap humid ocean air.
Windward Rain
Frequent showers on the windward side wet single-wall homes.
Plumbing Leaks
Slow drips under sinks and behind appliances feed hidden growth.
How we remove mold
How we remove mold
On Maui, mold returns unless the dampness or leak is controlled. We start by finding the source, from Upcountry humidity to a roof gap or a closed-up condo.
We contain the space first. In a Kihei condo or a Kula cottage, we close off the affected rooms with plastic and run HEPA air scrubbers so spores stay put.
We remove and clean. Moldy drywall, boards, and carpet come out, and solid wood is cleaned and treated without harsh chemicals.
We dry it out and help keep it dry. Dehumidifiers run until readings match a dry room. We’ll suggest humidity settings for Upcountry homes and rentals.

What to doBook an inspection so we can take moisture readings in the hidden spots.
What can be saved
What can be cleaned and what gets replaced
From Upcountry cottages to Kihei condos, what we keep depends on the material, how long it stayed damp, and how far growth spread. The inspection confirms each item.
Tile, glass, metal, and stone
Usually cleanedLanai tile, sliding glass, and stone counters wipe clean. Wet hardware near the ocean can pit, so we clean it early.
Treated framing and posts
Usually cleanedFraming with surface growth can be cleaned.
Board-and-batten walls
Depends on how deep it goesBoard-and-batten with a light film of growth can be cleaned; boards that went soft in the Upcountry damp are replaced.
Drywall in condos
Depends on how deep it goesCondo drywall with a few spots may clean. Panels where growth has gone through the paper are cut out.
Koa and wood furniture
Depends on how deep it goesKoa and other hardwood pieces usually clean with gentle methods. Softwood with deep growth may not.
Rental mattresses and linens
Depends on how deep it goesLinens often wash clean; mattresses with growth are usually replaced.
Clothing and shoes
Depends on how deep it goesAloha shirts, linens, and canvas shoes often wash clean. Leather slippers and bags with deep growth may be a loss.
Photos and documents
Depends on how deep it goesFamily photos and papers can sometimes be cleaned and preserved, but in Maui humidity it pays to act quickly.
Insulation
Usually removedAny insulation in a Maui home or condo that grew mold is pulled out and replaced.
Carpet and pad
Usually removedCarpet and pad with growth are usually replaced.
Ceiling tiles
Usually removedAcoustic ceiling tiles in condos that grew mold are thrown out and replaced.
Do You Need a Mold Test?
Often not. When the mold is visible and the cause is clear, like Upcountry dampness or a closed-up condo, testing rarely changes the plan. It helps when a guest or tenant reports a smell, or when a buyer or doctor needs documentation.
When testing makes sense, we’ll explain air and surface sampling and can coordinate an independent tester, which property managers often keep on file for guests.

Other restoration services we offer on Maui
Every job starts with a free inspection and estimate. Here’s how the 24 Hour Flood Pros team helps with each type of damage.
Fires and wind-blown smoke leave soot and odor. Soot is acidic and keeps staining surfaces, so cleanup starts early. We remove soot, treat odor at the source, clean what can be saved, and rebuild what can’t.
More about Fire and Smoke Damage
Kona storms and heavy trade-wind showers damage roofs from Haiku to Kihei. We dry the structure, remove damaged materials, and repair the ceilings and walls inside.
More about Storm Damage
Mold in condos, rentals, restaurants, or shops needs quick turnaround. We extract, dry, and clean on a plan built around reopening, and we document each step for your carrier.
More about Commercial Restoration
When you’re ready to rebuild, the same crew puts it back together, from drywall to cabinets to the final coat of paint, so there’s no second contractor to hire.

Insurance and claims
Mold remediation and your insurance claim
Sometimes. Many homeowners policies cover mold when it comes from a sudden, covered water event, like a burst pipe or a water heater that gives out. Mold from a slow leak or ongoing humidity is often excluded, and some policies cap mold coverage at a set amount.
Your policy decides what’s covered, not us. We work with all major insurance carriers, including State Farm, Allstate, Liberty Mutual, Farmers, American Family, Travelers, and Nationwide, and we keep the paperwork clear enough that your claim doesn’t stall.
Report it soon after you find it. Waiting can make it harder to show the mold came from a sudden event.
If a claim stalls, you can file a complaint with the Hawaii Insurance Division.
What your adjuster will ask for
- When you first noticed the mold or the smell
- What caused the moisture, and when it started
- Photos of the mold and any water damage
- Receipts for any work already done on the leak
What we send them
- Date-stamped photos of each affected area
- Moisture readings showing where the water is
- A line-by-line estimate for removal and rebuild
- One point of contact for your adjuster

Common questions
Maui mold remediation FAQs
How fast can 24 Hour Flood Pros get to me?
A crew can be there within 45 minutes. We work 24/7, including nights, weekends, and holidays, so you can call the moment you find mold or a leak.
Is black mold dangerous?
Any mold growing indoors should be removed, whatever its color. The CDC’s advice is that you don’t need to know the type of mold to deal with it. Mold can trigger allergies and asthma, so people with breathing problems or weak immune systems should stay away from it.
Can I clean mold myself?
For a small area, yes. The EPA says a patch under about 10 square feet, roughly 3 feet by 3 feet, can usually be cleaned with detergent and water while you wear gloves, eye protection, and a mask. Call a professional for anything larger, mold in the heating and air system, mold after sewage or flood water, or mold that keeps coming back.
Do I need a mold test before remediation?
Usually not if you can see the mold. Testing is most useful when you smell mold but can’t find it, or to confirm the cleanup worked.
Will the mold come back after remediation?
Not if the moisture is fixed. Mold comes back when the leak, the drainage problem, or the humidity is still there. That’s why every job starts with finding the source, and why we dry everything before the walls are closed.
Do I need to leave my home during mold remediation?
Usually not. We seal off the work area and filter the air, so most people stay home. For large jobs, or if someone in the house has breathing problems, we’ll tell you in advance if staying somewhere else makes sense.
How much does mold remediation cost on Maui?
It depends on how big the area is, what has to be removed, how hard it is to reach, and what it takes to stop the moisture. A bathroom wall costs far less than a whole crawlspace or attic. The inspection and estimate are free, so you know the cost before any work starts.
How long does mold remediation take?
A small area can take a few days. Crawlspaces, attics, and rooms that need rebuilding take longer. Your estimate includes a schedule.
Does Hawaii require a license for mold remediation?
Hawaii doesn’t issue a specific state license for mold remediation, so it’s worth checking a company’s training and certifications before you hire it. 24 Hour Flood Pros is an IICRC Certified Firm, #70120685.
