Sweating attic ducts, basement seepage, or a dripping ice maker line can feed mold. Our crew handles mold remediation in Raleigh, NC, finds the moisture behind it, and dries the space out. Call any time, day or night.
Many newer two-story homes have a finished room over the garage, often called a bonus room or FROG. Bonus rooms sit beside knee-wall attics where ducts run through hot, humid air. Condensation and leaky ductwork can feed mold in their ceilings and walls.
Raleigh’s humid summers make every small leak a bigger problem. A sweating duct, clogged AC drain, or leaking supply line can keep Raleigh drywall damp long enough for mold.
Low areas near Crabtree Creek flood in heavy storms. North Raleigh homes on slopes often have basements that flood when the clay is soaked.
Homeowners, property managers, and business owners call us about mold all year round. We work across Five Points, Oakwood, Cameron Village, North Hills, Boylan Heights, Brier Creek, Hayes Barton, Mordecai, Glenwood-Brooklyn, and Wakefield.
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 Raleigh homes
Around Raleigh, mold usually traces back to attic ducts, humid air, or water after heavy storms.
Rooms Over Garages
Bonus rooms surrounded by hot attic spaces collect condensation from ducts and poor air sealing.
Attic Ducts and Air Handlers
Sweating or leaky ductwork and clogged drains drip onto ceilings.
Bathrooms and Kitchens
Steam and slow leaks in Raleigh’s humid air grow mold behind tile and cabinets.
Crawl Spaces in Older Homes
Older homes on crawl spaces stay damp in summer.
Creek Flooding
Crabtree Creek and other streams can push water into low-lying homes.
Basements on Sloped Lots
Soggy red clay pushes water into basements on sloped lots.
How we remove mold
How we remove mold
In Raleigh, mold comes back unless the humidity or leak is fixed. We start by tracing it, often to the attic or ducts around a bonus room.
We contain the space. Plastic barriers and HEPA air scrubbers keep spores from drifting downstairs or into the ducts serving the bonus room.
We take out what mold has grown into. Bonus room drywall, knee wall insulation, wrapped ducts, and carpet with growth come out, and framing is cleaned and treated.
We dry and help prevent a repeat. Readings must match a dry room before repairs. We can point out duct sealing and insulation fixes for bonus rooms.

What can be saved
What can be cleaned and what gets replaced
From Holly Springs builds to Five Points bungalows, our call depends on the material, how long it stayed wet, and how far growth reached. The inspection confirms each item.
Usually cleanedDepends on how deep it goesUsually removed
Tile, glass, metal, and stone
Usually cleaned
Hard surfaces clean well.
Framing and roof decking
Usually cleaned
Rafters and OSB roof decking above a bonus room with surface growth can usually be cleaned and treated.
Bonus room drywall
Depends on how deep it goes
Drywall in a room over the garage with a few spots may clean. Panels soaked by a leaking duct or drain are cut out.
Ceiling texture
Depends on how deep it goes
Some textured ceilings clean; stained or soft sections are replaced.
Hardwood floors
Depends on how deep it goes
Oak floors in Triangle homes with surface mold clean up. Boards that cupped from humidity below are replaced.
Carpet
Depends on how deep it goes
Bonus room or basement carpet that grew mold on its backing is replaced.
Furniture
Depends on how deep it goes
Wood and metal furniture usually cleans. Futons and sectionals with growth deep in the cushions may not.
Photos and documents
Depends on how deep it goes
Photos and papers stored in a humid bonus room or basement can sometimes be restored by a document specialist.
Attic and knee wall insulation
Usually removed
Insulation with growth or soaked by a duct leak is replaced.
Duct insulation
Usually removed
Moldy duct wrap is replaced.
Carpet pad
Usually removed
Pad with growth is replaced.
Do You Need a Mold Test?
Usually not. If the mold is visible and the cause is clear, like a sweating duct or a flooded basement, testing seldom changes the plan. It helps more when you smell mold but can’t find it, or when a buyer, landlord, or tenant needs documentation.
If testing makes sense, we can explain the options and coordinate an independent tester.

Other restoration services we offer in Raleigh
Every job starts with a free inspection and estimate. Here’s how the 24 Hour Flood Pros team helps with each type of damage.
Water Damage
Crabtree Creek flooding, basement seepage, and supply line leaks soak Raleigh homes. We extract the standing water, set up dehumidifiers and air movers, and take moisture readings every day until the floors and framing test dry.
Fire damage in a home means soot on every surface and a smell that lingers in carpet and drywall. 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.
Hurricane remnants and ice storms bring down pines on Triangle roofs. We dry the structure, remove damaged materials, and repair the ceilings and walls inside.
Mold in NC State student housing, a North Hills restaurant, or an RTP office takes planning around people. We extract, dry, and clean on a plan built around reopening, and we document each step for your carrier.
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.
Call (919) 238-9459 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.

We inspect and find the source
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.
3
We close off the area
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.
4
We stop the moisture
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.
5
We remove moldy materials
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.
6
We clean and dry what stays
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.
7
We make the repairs
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.
8
Final check with you
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.
Musty bonus room over the garage?
Condensation from attic ducts can feed hidden mold. Call us for a free inspection.
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 North Carolina Department of Insurance.

Common questions
Raleigh 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 Raleigh?
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 North Carolina require a license for mold remediation?
North Carolina 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.
