Backups and seepage soak lower levels. 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 Kansas City homes
Many older Kansas City homes sit on stacked limestone or rubble foundations. Limestone foundations are sturdy, but water gets through the mortar after heavy rain. Paneled, carpeted basements trap that moisture.
Parts of Kansas City are served by combined sewers, which carry both stormwater and wastewater. In big storms they can back up through basement floor drains. On July 16, 2025, the city recorded 2.78 inches of rain, more than double the old record for that date.
Humid summers add steady background moisture, so lower levels stay damp even without a flood, and winter brings condensation on cold stone and block walls.
Homeowners, property managers, and business owners call us about mold all year round. We work across Brookside, Waldo, Westport, Crossroads, River Market, Northland, Midtown, Country Club Plaza, Hyde Park, and Armour Hills.

What’s included
Handling stone-foundation seepage and floor drain backups, sealing off the lower level, removing moldy finishes, HEPA cleaning, drying, and rebuilding.
Typical timeline
A closet or bathroom job usually wraps up in a day or two. A Kansas City lower level after a drain backup often needs a week or more.
How cost is set
Your estimate weighs whether sewage was involved, how much of the lower level grew mold, what comes out, and what gets rebuilt.

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 (816) 463-4959What 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 Kansas City homes
In Kansas City homes, mold usually traces back to old foundations, sewer backups, or summer humidity.
Crawl Spaces and Stone Foundations
Water seeps through mortar joints in older limestone foundations and dampens framing.
Attics
Hail-damaged roofs and ice dams let water into Kansas City insulation and sheathing.
Bathrooms in Older Homes
Leaking tubs and showers soak plaster and floor framing.
Ductwork in Damp Basements
Cool ducts sweat in humid lower levels and can grow mold.
Heavy Rain and Seepage
Saturated soil pushes water into basements after storms.
Sewer Backups
Kansas City’s combined sewers can push water up floor drains during big storms.
How we remove mold
How we remove mold
In KC basements, mold returns if seepage through the foundation or backups from the floor drain keep happening. We start with the water.
We contain the lower level. Plastic barriers and HEPA air scrubbers keep spores out of the upstairs and the furnace.
We remove contaminated materials. Paneling, drywall, carpet, and insulation touched by mold or backup water come out, and framing and stone are cleaned and disinfected.
We dry the lower level and rebuild. New finishes go in only after the stone, slab, and framing read as dry as an upstairs room.

What it usually meansMold behind paneling on limestone walls, or in the joist bays above
What to doRemove the paneling and test the stone and joists with a meter.
What can be saved
What can be cleaned and what gets replaced
In Kansas City homes, cleaning versus replacing depends on the material, whether backup water was involved, and how long the lower level stayed damp. The inspection confirms each item.
Concrete, tile, glass, and metal
Usually cleanedHard surfaces clean and disinfect well.
Limestone foundation walls
Usually cleanedSurface growth on stone cleans once seepage is addressed.
Wood framing
Depends on how deep it goesStuds with surface growth clean; wood softened by long seepage is replaced.
Basement drywall and paneling
Depends on how deep it goesMaterials touched by backup water or deep growth are removed.
Hardwood floors upstairs
Depends on how deep it goesMain-floor hardwood rarely needs more than a cleaning unless water came up from the basement and swelled the boards.
Basement carpet
Depends on how deep it goesCarpet touched by backup water is replaced.
Furniture and stored items
Depends on how deep it goesSolid pieces clean; boxes and fabrics after a backup often can’t be saved.
Photos and documents
Depends on how deep it goesKeepsakes stored in a KC basement can sometimes be saved by a restoration specialist, especially if they come out of the damp quickly.
Insulation
Usually removedInsulation with growth or backup contamination is replaced.
Carpet pad
Usually removedPad under lower-level carpet that soaked up backup water or grew mold is hauled out with the carpet.
Particleboard furniture
Usually removedPieces that swelled and grew mold are thrown out.
Do You Need a Mold Test?
Usually not. When mold is visible and the source is a backup or seepage, testing seldom changes what needs to be done. Testing is more useful when you smell mold but can’t find it, or when a buyer or landlord needs documentation.
If testing would help, we’ll explain the options and can coordinate an independent tester for before-and-after results.
Stop the water behind the mold
Other restoration services we offer in Kansas City
Every job starts with a free inspection and estimate. Here’s how the 24 Hour Flood Pros team helps with each type of damage.
After a fire, smoke and soot spread through Kansas City homes room by room. 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
Hail and severe wind tear up roofs across the Kansas City metro. We dry the structure, remove damaged materials, and repair the ceilings and walls inside.
More about Storm Damage
Mold in offices, restaurants, or apartment basements 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.

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.

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 Missouri Department of Commerce and Insurance or the Kansas Insurance Department.
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

Kansas City 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 Kansas City?
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.
Do Missouri or Kansas require a license for mold remediation?
Neither Missouri nor Kansas has a specific state license for mold remediation. Contractor licensing for the repair work is handled by cities and counties on both sides of the state line. Ask about local licensing and IICRC training.
