Mold help
Mold in Las Vegas homes
In the Mojave, mold nearly always points to a leak, often from hard Las Vegas water. The valley’s very hard water leaves mineral scale that wears out supply lines, valves. Water heaters, and a slow drip inside a cabinet or wall can feed mold for months.
Attic AC systems work nearly year-round here. When scale clogs a condensate line, the drain pan can overflow onto drywall ceilings without anyone noticing.
Seasonal and second homes are another risk. A closed house with the water on can hide a leak for weeks. Monsoons like the July 2022 storms that flooded parts of the Strip find gaps in tile roofs.
Homeowners, property managers, and business owners across Clark County 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 (702) 350-1675What 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 Las Vegas homes
In Las Vegas, mold nearly always comes from a leak: plumbing, the AC, or the roof during monsoon season.
Slab Leaks
Hard water and shifting soil can lead to leaks under slab floors that wet flooring and baseboards.
Attic AC Systems
Clogged condensate lines and overflowing pans drip onto ceilings and insulation.
Kitchen and Bathroom Plumbing
Scale-worn supply lines, faucets, and valves leak inside cabinets and walls.
Water Heater Closets
Corroded tanks and fittings leak slowly into closets and garages.
Monsoon Roof Leaks
Summer storms push water through cracked tiles and flat roof seams.
Ice Maker and Dishwasher Lines
Small supply lines behind appliances can leak for weeks before anyone notices.
How we remove mold
How we remove mold
In the desert, mold stops when the water stops. We start by finding the leak, whether it’s a supply line, the AC drain, the water heater, or the roof.
We seal off the work area. Plastic sheeting and HEPA air scrubbers keep spores from reaching the AC returns and other rooms.
We remove what mold has grown into. Moldy drywall, cabinet bases, insulation, and flooring come out, and framing is cleaned and treated.
We dry and rebuild. Southern Nevada’s low humidity helps, and we confirm dry readings before putting the walls and cabinets back.

What can be saved
What can be cleaned and what gets replaced
In Las Vegas homes, cleaning versus replacing depends on the material and how long the leak ran. The inspection confirms each item.
Tile, stone, glass, and metal
Usually cleanedHard surfaces clean well.
Framing and roof decking
Usually cleanedStuds, roof decking, and trusses with surface growth from a valley leak can be cleaned and treated in place.
Stucco and block walls
Depends on how deep it goesSurface growth cleans once the leak is fixed.
Drywall
Depends on how deep it goesSurface spots may clean; drywall soaked by a long leak is replaced.
Cabinet bases
Depends on how deep it goesSolid wood may clean; particleboard that swelled is replaced.
Laminate and wood floors
Depends on how deep it goesSurface mold cleans; flooring that trapped water is replaced.
Furniture
Depends on how deep it goesSolid wood and metal furniture usually cleans. Sofas and mattresses with growth deep in the padding may not.
Photos and documents
Depends on how deep it goesWet photos and papers can sometimes be dried and restored by a document specialist, though desert heat can make them brittle.
Attic insulation
Usually removedBlown-in attic insulation soaked by an AC overflow or monsoon leak is pulled out and replaced.
Carpet pad
Usually removedPad with growth is replaced.
Particleboard shelving
Usually removedSwollen, moldy particleboard is thrown out.
Do You Need a Mold Test?
Usually not. In Las Vegas, the cause is often a specific leak, and if you can see the mold, testing rarely changes the plan. Testing helps when you smell mold but can’t find it, or when a buyer, landlord, or doctor needs a report.
When testing helps, we’ll explain sampling and can bring in an outside tester, which is useful if you sell or rent.

Other restoration services we offer in Las Vegas
Every job starts with a free inspection and estimate. Here’s how the 24 Hour Flood Pros team helps with each type of damage.
AC and electrical fires peak in summer heat. 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 storms damage tile and flat roofs. We dry the structure, remove damaged materials, and repair the ceilings and walls inside.
More about Storm Damage
Mold in a restaurant kitchen, a hotel room block, or an office near the Strip needs a fast, contained plan. 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 Nevada Division of Insurance.
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
Las Vegas 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 Las Vegas?
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 Nevada require a license for mold remediation?
Nevada 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.
