Finding mold raises a lot of questions fast: Is it dangerous? Can I clean it myself? Will insurance pay? This mold remediation FAQ answers the questions we hear most from homeowners, landlords and property managers across Florida, Texas, New Jersey and New York. If you’re already looking at mold, All Dry USA offers free inspections. Call 1-888-998-2379.
What Is Mold Remediation?
Mold remediation is the process of finding the moisture source, containing the affected area, physically removing mold growth and contaminated materials, cleaning the surrounding area, and confirming it’s done. It’s different from simply “killing” mold with bleach: dead mold spores can still trigger allergies, and bleach doesn’t soak into porous materials like drywall and wood. Professional remediation follows the IICRC S520 standard and EPA mold cleanup guidance.
What Causes Mold in Homes and Buildings?
Mold needs three things: spores (always present in the air), food (drywall paper, wood, carpet, dust) and moisture. Moisture is the only one you can control. The most common sources we find:
- Plumbing leaks, burst pipes and failed water heaters, dishwashers or washing machine hoses
- Roof leaks and storm damage, including hurricane damage in Florida and nor’easters in New Jersey and New York
- Flooding and water damage that wasn’t dried professionally
- High indoor humidity, a year-round problem in Florida and along the Texas Gulf Coast
- Clogged AC condensate lines and poorly insulated ductwork
- Basement seepage and foundation cracks, common in older New York and New Jersey homes
Signs You May Need Professional Mold Remediation
- A persistent musty or earthy smell, even when you can’t see mold
- Visible growth larger than about 10 square feet, roughly a 3 ft by 3 ft patch
- Staining, bubbling paint or soft drywall on walls and ceilings
- Mold that returns after cleaning
- Allergy or asthma symptoms that improve when you leave the building
- Any water damage that sat for more than 48 hours
Mold Rules by State: FL, TX, NJ and NY
Mold regulations vary a lot across the states we serve, and they affect who can do what on your project:
- New York: State law (Labor Law Article 32) requires licensed mold assessors and licensed remediation contractors for projects over 10 square feet. The company that writes the assessment can’t also do the remediation on the same project. See our New York mold removal services.
- Texas: The Texas Department of Licensing and Regulation (TDLR) licenses mold assessors and remediators for projects of 25 contiguous square feet or more, and the same company can’t both assess and remediate the same project. See Texas mold remediation.
- Florida: Florida’s DBPR licenses mold assessors and remediators for jobs over 10 square feet, with conflict-of-interest limits on assessing and remediating the same property. See Florida mold remediation.
- New Jersey: New Jersey has no state mold licensing law. That makes it more important to hire a company with IICRC-certified technicians, proper insurance and a written scope of work. See New Jersey mold removal.
Where the law requires an independent assessor, All Dry USA works alongside licensed third-party assessors so your project stays compliant and your clearance results hold up with insurers, buyers and tenants.
How the All Dry USA Mold Remediation Process Works
- Free inspection: We use moisture meters and thermal imaging to find the moisture source and the full extent of growth, including inside walls.
- Containment: Plastic barriers and negative air pressure with HEPA filtration keep spores from spreading to clean areas.
- Removal: Moldy drywall, insulation and carpet are removed and bagged. Salvageable framing and hard surfaces are HEPA-vacuumed, cleaned and treated.
- Drying and moisture repair: We dry the structure and fix or coordinate repair of the leak, so the mold doesn’t come back.
- Clearance: Post-remediation verification, including air or surface sampling where required, confirms the area is back to normal.
- Rebuild: We replace drywall, flooring and finishes, so you don’t need a second contractor.
Frequently Asked Questions
How much does mold remediation cost?
Small, contained jobs like a single bathroom or closet often run $1,500 to $3,500. Multi-room projects, attics, crawl spaces or HVAC systems commonly run $5,000 to $15,000 or more. The size of the affected area, how much material has to be removed, and access drive the price. We give a written estimate after a free inspection.
Can I clean mold myself?
The EPA says homeowners can usually clean small areas of mold, under about 10 square feet, on hard surfaces. Larger areas, mold inside walls or HVAC systems, mold after sewage or flood water, or anyone in the home with asthma or a weakened immune system are reasons to hire a professional.
Is black mold dangerous?
Color doesn’t tell you how dangerous a mold is. Many molds look black, and any mold growing indoors can trigger allergies, asthma and irritation. Treat all indoor mold growth the same way: fix the moisture and remove the growth properly.
Does insurance cover mold remediation?
Usually only when the mold results from a covered, sudden event such as a burst pipe or appliance failure, and many policies cap mold coverage. Mold from long-term leaks, humidity or deferred maintenance is often excluded. We document the cause and work directly with your adjuster.
How long does mold remediation take?
Most residential projects take one to five days, plus time for drying and any post-remediation clearance testing. Large or commercial projects can take longer.
Will mold come back after remediation?
Not if the moisture source is fixed. Mold needs moisture to grow. Remediation removes the growth, but the leak, humidity or drainage problem has to be corrected too, which is why we address the water source as part of every job.
Do I need to leave my home during mold remediation?
For small, contained projects most families stay home. For large projects, or if someone in the home is sensitive, we may recommend staying elsewhere until the work and clearance testing are complete.
Do mold remediation companies need a license?
It depends on the state. New York, Texas and Florida license mold assessors and remediators for larger jobs. New Jersey doesn’t have a state mold license, so check for IICRC certification and insurance.
