I Think I Have Mold, Now What?

The short answer: If you see or smell mold, find and stop the water source, keep the area dry, and try not to disturb it. Then call a licensed mold inspector. A mold inspection finds out what is going on and puts it in writing. It does not remove the mold. Removal, called remediation, is a separate job done by a different company.

Finding a dark spot on the ceiling, or catching a musty smell you cannot explain, is stressful. The good news is that you do not have to guess what to do next. Here is what to do today, what a mold inspection really is, how sampling fits in, what a mold inspection does not cover, and how to move forward. This guide is for homeowners in Jacksonville, Orange Park, Green Cove Springs, Middleburg, St. Augustine, Fernandina Beach, Palatka, Macclenny and the surrounding area, as well as Southeast Georgia.

What should I do first if I think I have mold?

Start with the water, because mold needs moisture to grow. The EPA says the key to mold control is moisture control, and that if you clean up mold but do not fix the water problem, the mold will most likely come back [1]. Here is a simple first-day checklist:

1. Find and stop the leak. Look at plumbing, the roof, windows, the air conditioner drain line and the area around appliances.

2. Dry wet areas fast. The EPA says that if wet materials are dried within 24 to 48 hours, mold usually will not grow [1].

3. Do not paint or caulk over it. The EPA warns that paint over a moldy surface is likely to peel [1].

4. Be careful with the air conditioning. If you suspect mold in or near your HVAC system, the EPA says not to run it, because it could spread mold through the house [1].

5. Do not scrub or tear into a big area. Disturbing hidden mold can release a lot of spores, so the EPA suggests an experienced professional when you suspect hidden mold [1].

6. Think about your health. If anyone in the home has asthma, allergies or a weak immune system, the CDC notes they can have stronger reactions [2]. Talk with a doctor about symptoms.

For a small patch, the EPA says that if the moldy area is less than about 10 square feet (roughly a 3 foot by 3 foot patch), you can in most cases handle the cleanup yourself, using protective gear. If it is larger, or there has been a lot of water damage, the EPA points you toward professional guidance [1].

What is a mold inspection?

A mold inspection is a professional look at your home to figure out whether there is mold, where it is, how far it has spread, and, most importantly, why it is there. Florida's mold-related services law describes this kind of work as a process that includes physical sampling and a detailed review of the building's history and an inspection, used to form a starting conclusion about the origin, identity, location and extent of mold growth [3].

In everyday terms, a mold inspection usually covers:

• Your story. Past leaks, water damage, repairs, smells, and where you have noticed problems.

• A careful inspection. Looking at the visible areas and the likely hiding spots for moisture.

• Sampling when it makes sense. More on that below.

• A written report. What was found, the likely moisture source, and what to do about it.

The cause: flashing that was not installed correctly where the roof meets the wall let rain get in.

The result: water damage inside the wall, found during a mold inspection.

Florida licenses mold-related services under Chapter 468, Part XVI of the Florida Statutes. The law sets training and licensing requirements for anyone who does this work, and it prohibits using the state's official professional titles without meeting them [4]. That is a good reason to ask any company about their license.

What is mold sampling, and do I need it?

Sampling means collecting a small piece of evidence, such as a swab or tape lift from a surface or a sample of the air, and sending it to a lab. Here is the honest picture, straight from the government sources:

• The EPA says that in most cases, if visible mold is present, sampling is unnecessary [1].

• The CDC does not recommend routine mold testing. It explains that people react to mold differently, and that there are no set standards for what is an acceptable amount of mold in a home [2]. The EPA agrees that no federal limits exist for mold or mold spores [1].

• The EPA also says sampling should be done by professionals with specific experience in designing sampling plans and interpreting results [1].

So when does sampling help? The EPA notes that surface sampling may be useful to confirm an area was properly cleaned after cleanup or remediation [1]. Sampling can also be part of a professional's investigation when mold is suspected but not visible, such as a musty smell with no obvious source, or when you want clear documentation. This is a case where a licensed mold inspector earns their fee: knowing when a sample is worth taking, and when the better answer is simply to find the water and fix it.

A word about store-bought test kits: The CDC says you cannot rely on sampling and culturing to know whether someone might become sick [2]. A kit that tells you “mold found” does not tell you where it came from, how much there is, or what to do. A professional inspection answers those questions.

What a mold inspection does NOT include

This is where many homeowners get surprised, so here it is plainly.

1. Mold removal (remediation). Florida defines mold remediation as the removal, cleaning, sanitizing, demolition or other treatment of mold or mold-contaminated material [3]. That is a different job, with a different license, done by a different company. Florida law adds a built-in safeguard: the professional who inspects your home may not perform mold remediation on a structure that they or their company inspected within the last 12 months (there is an exception for certain licensed contractors). They also may not accept payment for referring you to a remediator [4]. In plain terms, the person who tells you what is wrong is not supposed to profit from the fix. That keeps the inspection honest.

2. Repairs. A mold report can point to the leak, the roof problem or the drainage issue behind the mold. Fixing the plumbing, roof, windows or air conditioner is work for the right tradesperson.

3. A medical opinion. An inspection looks at the house, not your body. The CDC says the health effects of mold differ from person to person [2]. If you are having symptoms, see your doctor.

4. A promise that mold will never return. The EPA says it is impossible to get rid of all mold and mold spores indoors, and that spores will not grow if moisture is not present [1]. Controlling moisture is what keeps mold away.

What are the next steps after a mold inspection?

1. Read the report and fix the water source first. Cleanup without a fix usually fails [1].

2. If remediation is needed, hire a licensed mold remediator. In Florida, ask to see the license. The state agency that handles it is the Department of Business and Professional Regulation. The EPA also advises hiring a contractor with real mold experience, checking references, and asking them to follow recognized guidelines [1].

3. Get quotes. Because the inspector and the remediator are separate, you are free to compare bids.

4. Confirm the cleanup worked. The EPA says cleanup is not finished until the water problem is fixed, visible mold and moldy odors are gone, and the area shows no new signs of mold or water damage. As noted above, surface sampling may help confirm it was cleaned properly [1].

5. Keep it from coming back. The CDC suggests keeping indoor humidity no higher than 50 percent, using exhaust fans that vent outside, and fixing leaks promptly [2]. After a flood, the CDC says to clean up and dry out within 24 to 48 hours [2].

Southeast Georgia homeowners: what to know

Hanna Home Services takes mold inspection jobs in Southeast Georgia too. The approach is the same on both sides of the state line: inspection only, never removal, so your report stays independent.

Rules are different across the state line. According to the Georgia Department of Public Health, indoor air quality is not a regulated program in Georgia, and mold inspections, testing and remediation practices have no enforceable state or federal standards [5]. That makes it important to ask good questions before you hire anyone, including us:

• What training and credentials do you hold?

• What exactly is included, and will I get a written report?

• Do you also sell mold removal? If so, how do you keep the inspection independent?

• When do you recommend sampling, and why?

Frequently asked questions

Does a mold inspection include mold removal?

No. A mold inspection finds and documents mold and the moisture behind it. Removal is a separate service performed by a licensed mold remediator in Florida.

Do I need mold testing if I can already see mold?

Not always. The EPA says that in most cases, if visible mold growth is present, sampling is unnecessary [1]. An inspection is still valuable to find the moisture source and check for hidden mold.

How fast can mold grow after water damage?

The EPA says drying wet materials within 24 to 48 hours usually prevents mold growth [1]. That is why acting quickly after a leak matters.

Can I clean mold myself?

For a patch under about 10 square feet, the EPA says in most cases you can, with protective gear and by fixing the moisture problem. For bigger areas, hidden mold, sewage water or HVAC contamination, the EPA recommends professional help [1].

Is mold in my house making me sick?

Mold affects people differently. The CDC says exposure may cause a variety of health effects or none at all, and people with asthma, allergies or weakened immune systems can react more strongly [2]. Your doctor is the right person for health questions.
