Mold help
Reno’s high-desert air dries surfaces quickly, which can hide a slow leak inside a wall. The usual culprits are winter freezes, evaporative coolers, and snowmelt.
Cold snaps are a big one. When overnight temperatures drop well below freezing, pipes in exterior walls and crawl spaces can split, and the leak often isn’t found until the thaw. Soaked insulation and drywall in that wall may grow mold unseen.
Many homes still use rooftop swamp coolers. A cracked cooler pan or stuck float can send water into the Reno attic or ducts all summer. Rivers add risk too. The 1997 New Year’s flood sent the Truckee through downtown, and spring runoff still raises local creeks.
Homeowners, property managers, and business owners across Washoe County, Storey County, Lyon County, Douglas County, and Carson City call us about mold all year round.

Found 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 (775) 899-8753Check above and around the mold for a drip, a damp spot, or a stain. Stopping the water stops the mold from growing.
Run the air conditioning or a dehumidifier. The EPA recommends keeping indoor humidity below 60%, ideally between 30% and 50%.
Photograph the mold and any water damage before anything is cleaned. Your insurance company may ask for them.
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.
Anyone with asthma, allergies, or a weak immune system should stay out of the area until the mold is gone.
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.
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.
Fans blowing across mold carry the spores into other rooms.
The system will blow spores through the whole house. Leave it off until it’s been checked.
If you can see mold, the EPA says testing usually isn’t needed. Spend the money on finding the leak.
Where mold hides
In the Truckee Meadows, mold usually traces back to frozen pipes, evaporative coolers, or spring runoff.
Runoff and condensation under older homes dampen joists and insulation.
Cracked pans and stuck floats drip into attic insulation and down ducts.
Galvanized supply lines and old tub drains in older homes leak slowly behind tile and vanities.
Moist air from a poorly maintained cooler can grow mold inside the ducts.
The Truckee River and local creeks can push water into nearby homes.
Pipes in exterior walls and crawl spaces split during hard freezes.
How we remove mold
In Reno, mold stops when the water stops. We start by finding the source, whether it’s a split pipe, a cooler leak, or runoff.
We contain the work zone. Plastic barriers and HEPA air scrubbers keep spores out of the rest of the house and away from the cooler or furnace ducts.
We remove and clean. Moldy drywall, insulation, and cooler ducting come out, and framing is cleaned and treated.
We dry and rebuild. Northern Nevada’s low humidity helps the drying, and we confirm normal readings before closing up walls.

What can be saved
Around Reno and Sparks, what we clean or replace depends on the material, how long the leak lasted, and how far growth spread. The inspection confirms each item.
Hard surfaces clean well.
Studs, joists, and sheathing in Truckee Meadows homes with surface growth can be cleaned and treated in place.
Stucco and block clean up once the split pipe or cooler leak is fixed and the wall dries.
Drywall soaked by a split pipe is usually replaced.
Hardwood over a Truckee Meadows crawl space with only surface mold can be cleaned; boards warped by runoff underneath get swapped out.
Carpet soaked by a split pipe that grew mold on its backing is replaced.
Dressers and tables made of solid wood usually recover. Overstuffed sofas that sat in a wet room for weeks often don’t.
Albums soaked when a pipe burst can sometimes be frozen, then restored by a conservator, if they’re bagged quickly.
Wall, attic, and crawl space insulation with growth is replaced.
Moldy cooler pads and duct liner are replaced.
Pad with growth is replaced.
Most of the time, no. If the cause is a split pipe or a cooler leak and you can see the growth, a lab test won’t change our fix. Testing earns its cost when there’s an odor with no visible source, or when someone needs paperwork for a sale or lease.
When testing is worth doing, we’ll explain air and surface sampling and can coordinate an independent tester for before-and-after results.
Stop the water behind the mold
Every job starts with a free inspection and estimate. Here’s how the 24 Hour Flood Pros team helps with each type of damage.
A pipe that splits in a cold snap or runoff from the Truckee can soak a Reno 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.
More about Water Damage
Wood stoves and wildfire smoke leave soot behind. 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
Washoe zephyr winds and heavy Sierra snow damage roofs across the valley. We dry the structure, remove damaged materials, and repair the ceilings and walls inside.
More about Storm Damage
Mold in a Midtown restaurant, casino back-of-house area, or Sparks warehouse takes planning to keep things running. 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.

Our process
Call (775) 899-8753 any time, day or night, including weekends and holidays. Tell us what you’re seeing or smelling, and where. We’ll send a crew right away.
The 24 Hour Flood Pros team looks for the moisture feeding the mold. We use moisture meters to find water hiding inside walls, under floors, and in the crawlspace. We take photos for your insurance. The inspection is free.
We seal the work area with plastic and set up HEPA air scrubbers, so spores don’t spread to clean rooms. The heat and air stay off in that area while we work.
We dry out the water and show you what’s causing it. If a plumber, a roofer, or an HVAC tech needs to fix a leak, we tell you before we go further.
Drywall, insulation, and carpet pad with mold growing in them are cut out, bagged, and carried out. That way we only remove what really needs it.
Framing, subfloor, and other solid surfaces are HEPA-vacuumed, cleaned, and treated. Then we dry them until they read close to a dry room elsewhere in the house.
When you’re ready, the 24 Hour Flood Pros team fixes the damage. We replace drywall, install cabinets, and finish with fresh paint. Our goal is to make your home look the way it did before.
Before we take the plastic down, we check the area for any mold or dust left behind. Then we walk through it with you and send the final records to your insurance company to close out the claim.
A pipe that split during a cold snap can soak the wall and grow hidden mold. Call us for a free inspection.
Insurance and claims
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.

Common questions
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.
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.
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.
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.
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.
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.
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.
A small area can take a few days. Crawlspaces, attics, and rooms that need rebuilding take longer. Your estimate includes a schedule.
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.
