Mold help
Mold in Tucson homes
Tucson has one of the largest collections of historic adobe homes in the country, and many were later covered in hard cement stucco. Adobe needs to breathe, and cement stucco traps moisture inside the wall. The base stays damp, and the inside plaster crumbles and molds.
Parapet roofs add risk. Flat Tucson roofs drain through scuppers behind parapets. When one clogs in a monsoon, water ponds and seeps into the ceilings below.
Evaporative coolers are still common across Tucson. A cracked cooler pan, worn float, or soggy pads can leak into the Tucson attic or send humid air through the ducts.
Homeowners, property managers, and business owners call us about mold all year round. We work across Sam Hughes, Armory Park, Barrio Viejo, El Presidio, Catalina Foothills, Midtown, Rincon Heights, Dunbar Spring, Menlo Park, and Civano.

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 Tucson homes
In Tucson, mold usually traces back to trapped moisture in adobe walls, parapet roofs, or evaporative coolers.
Adobe Walls Under Cement Stucco
Hard stucco traps moisture in adobe, leaving damp wall bases and crumbling interior plaster.
Parapet Roofs and Scuppers
Clogged scuppers let monsoon water pond and seep into ceilings.
Bathrooms in Older Homes
Old tile showers and drains leak into plaster walls and floors.
Evaporative Coolers
Cracked pans and soggy pads drip into attics and send moist air through ducts.
Monsoon Wash Flooding
The Rillito and other washes can overflow into nearby homes.
Old Galvanized Lines in Midtown Homes
Galvanized supply pipes in 1950s houses corrode from the inside and start weeping into walls.
How we remove mold
How we remove mold
In Tucson, mold returns unless trapped moisture or the leak is addressed. We start by finding the source, whether it’s an adobe wall, a scupper, or a cooler.
We contain the area. Plastic barriers and HEPA air scrubbers keep spores from spreading through the house and cooler ducts.
We remove carefully. In historic homes, we remove only what mold has ruined and protect original plaster, vigas, and wood where possible.
We dry and restore. Adobe needs slow, steady drying, and readings must return to normal before plaster and finishes are restored.

What to doAsk us to test behind the plaster and ceilings with a meter.
What can be saved
What can be cleaned and what gets replaced
In Tucson homes, from historic adobes to newer stucco, cleaning versus replacing depends on the material and how long moisture was trapped. The inspection confirms each item.
Saltillo tile, brick, and glass
Usually cleanedHard surfaces clean well.
Vigas and wood beams
Usually cleanedPonderosa vigas and beams with surface growth can usually be cleaned and treated while preserving the original wood.
Adobe walls
Depends on how deep it goesAdobe can often be dried and repaired; badly eroded sections need rebuilding.
Lime and mud plaster
Depends on how deep it goesSound plaster cleans; crumbling sections are replastered with breathable materials.
Drywall in newer homes
Depends on how deep it goesDrywall in a Foothills or Oro Valley home with a few spots may clean. Panels soaked by a cooler leak are cut out.
Carpet
Depends on how deep it goesCarpet in a room that took monsoon water or wash runoff and grew mold on its backing is replaced.
Furniture
Depends on how deep it goesMesquite and wood furniture usually cleans. Cushions with deep growth may not.
Photos and documents
Depends on how deep it goesFamily photos and papers can sometimes be restored by a document specialist, though the desert heat can curl them quickly.
Attic insulation
Usually removedInsulation above a ceiling soaked by a cooler or parapet leak is pulled out and replaced.
Cooler pads and duct liner
Usually removedMoldy aspen pads and fiberglass duct liner from a swamp cooler system are thrown out and replaced.
Carpet pad
Usually removedPad with growth is replaced.
Do You Need a Mold Test?
Most of the time, no. If you can see the growth and the cause is a leaking cooler or a ponded roof, a lab report won’t change the cleanup. Sampling earns its keep when there’s an odor with no visible growth, or when a buyer or property manager asks for paperwork.
If testing makes sense, we can explain the options and coordinate an independent tester. For historic homes, documentation can also help guide restoration decisions.
Stop the water behind the mold
Other restoration services we offer in Tucson
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 leave soot in plaster and vigas. 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
Monsoon microbursts and hail damage flat and parapet roofs across the Tucson valley. We dry the structure, remove damaged materials, and repair the ceilings and walls inside.
More about Storm Damage
Mold in restaurants, shops, or student housing needs careful planning. 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 Arizona Department of Insurance and Financial Institutions.
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
Tucson 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 in Tucson?
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 Arizona require a license for mold remediation?
Arizona 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.
