Mold help

The Treasure Valley stays dry most months, so Boise mold usually traces to one water source. Spring snowmelt raising groundwater around basements, winter condensation in closed-up homes, and leaks from ice dams are the big three.
Basements are the most common trouble spot. When foothill snowmelt keeps the soil saturated, water can seep through block walls and window wells. It soaks drywall and carpet in finished lower levels.
Winter brings the other problem. With windows shut for months, moisture from cooking and showers collects on cold outside walls, in closets, and behind dressers. Mold grows where the air doesn’t move.
Homeowners, property managers, and business owners across Ada, Canyon, Elmore, Gem, and Boise counties 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 (208) 618-2630Check 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
Boise mold almost always traces back to snowmelt, winter condensation, or a leak from above.
Older Boise homes on crawl spaces take on groundwater during snowmelt, which feeds mold on joists and insulation.
Meltwater backing under shingles soaks attic insulation and sheathing near the eaves.
In Boise winters, steam and dryer moisture condense on poorly vented walls and ceilings.
Cold exterior walls collect condensation where air doesn’t circulate.
Snowmelt and groundwater seep through foundation walls and window wells into drywall and carpet.
A frozen pipe or slow plumbing leak can soak a wall before anyone sees it.
How we remove mold
Mold comes right back if the basement keeps taking on water or the attic keeps getting wet. We start by pinpointing the source, from a window well to an ice dam.
We set up containment. Plastic sheeting and HEPA air scrubbers keep spores from drifting upstairs or into the HVAC system.
We remove the materials mold has grown into. Basement drywall, carpet, and attic insulation with growth come out, and studs and joists are cleaned and treated.
We dry the space and rebuild. Moisture readings must match a dry room before we put the basement or ceiling back together.

What can be saved
In Boise homes, whether we clean or replace depends on the material, how long snowmelt or condensation fed the growth, and how far it reached. Here’s the usual pattern, and the inspection confirms it.
Basement slabs, tile, and window frames clean well.
Floor joists and studs in Treasure Valley homes with only surface growth can usually be cleaned and sealed.
Surface growth cleans, but the wall needs drying and the water source addressed.
Drywall that wicked snowmelt is cut out above the stained line; firm sections can stay.
Surface mold cleans, but boards rotted from below are replaced.
Carpet with growth on the backing after seepage is usually replaced.
Solid furniture often cleans. Cardboard boxes and fabric with growth usually can’t be saved.
A specialist can sometimes recover them if they’re dried quickly.
Batt insulation in attics and crawl spaces that grew mold after snowmelt or an ice dam is pulled out and replaced.
Pad that soaked up groundwater and grew mold is replaced.
Basement ceiling tiles with growth are thrown out.
Usually not. If you can see the mold and the cause is clear, like snowmelt in the basement, testing rarely changes the plan. Testing is more useful when there’s a smell but no visible growth, or when a buyer, landlord, or doctor asks for documentation.
When a test makes sense, we’ll explain air and surface sampling and can bring in an outside tester for before-and-after reports.
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.
Snowmelt seepage and burst pipes soak basements and walls. 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
Furnaces and wood stoves work hard in Boise winters. 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
When a summer windstorm lifts shingles or a heavy snow year stresses the roof, rain and meltwater find the attic. We dry the structure, remove damaged materials, and repair the ceilings and walls inside.
More about Storm Damage
Mold in an office, rental, or shop 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.

Our process
Call (208) 618-2630 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.
Water seeping through a Boise foundation often feeds hidden mold behind drywall and carpet. 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 Idaho Department 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.
Idaho 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.
