The first 24–72 hours
Do not disturb a large area of growth to get a better photo
Safety EPA’s guidance is that a moldy area of less than about 10 square feet, roughly a 3 foot by 3 foot patch, can in most cases be handled by the homeowner; larger areas are a job for someone equipped for it. Photograph from the doorway rather than scraping, brushing or pulling material away. The EPA cleanup page describes the protective equipment it recommends for anyone who does handle mold.[4][5]
Find and stop the moisture that feeds it
EPA’s cleanup guidance is to fix plumbing leaks and other water problems as soon as possible and to dry all items completely. Note the source, the date you found it and the time you stopped it, even if the source turns out to be humidity rather than a leak.[5]
Switch off the air handler if you think the system is involved
Safety EPA says not to run the HVAC system if you know or suspect that it is contaminated with mold, because it could spread mold throughout the building. If growth is near a register, on a filter or in the air handler closet, write down the time you switched the system off and photograph the filter and the nearest registers before anything is cleaned.[4]
Write down when you first saw it, room by room
The first-seen date is the fact everything else hangs on. Record it per room, and record separately the last date you are sure the surface was clean. An older dated photo of the same wall while it was clean is the start of the timeline.
Measure each patch before anyone cleans it
Hold a tape measure across the longest dimension and then the widest, photograph both readings, and write the two numbers into the caption. Florida’s statutory definitions of mold assessment and remediation and EPA’s cleanup guidance both use a 10 square foot figure, so the measurement is worth taking carefully.[1][4]
Mold is a consequence: record the moisture source, the first sighting and the spread
A mold record has three dates for each affected room: when the moisture arrived, when growth was first seen and when it was last measured. CDC states that if mold is growing in your home, you need to clean up the mold and fix the moisture problem, which is why the source comes first in the record. Fill in the table below for every room, and write “unknown” where you cannot say.[6]
| Moisture source | Date of source | Where mold showed | Date first seen | Size |
|---|---|---|---|---|
| Slow leak at the toilet supply line, hall bathroom | Unknown, before 2026-05-20 | Hall bathroom, wall behind toilet | 2026-06-02 | 30 by 25 cm |
| Same leak, water under the floor | Unknown, before 2026-05-20 | Bedroom 2, baseboard on the shared wall | 2026-06-09 | 90 by 8 cm |
| Condensation at the air handler drain pan | 2026-06-14, pan found overflowing | Air handler closet, wall and cabinet base | 2026-06-14 | 20 by 20 cm, filter discoloured |
Add a row each time growth appears somewhere new, and re-measure existing patches every few days while the moisture problem is being fixed. A patch that stops growing after the leak is repaired ties the mold to the source.
Why the record is about the source and the extent, not a species
CDC does not recommend mold testing. Its position is that there are no set standards for what is and is not an acceptable quantity of mold, and that the response to visible growth is the same regardless of kind: clean it up and fix the moisture problem. That is CDC’s position, and it shapes what a documentation record should contain. A lab report naming a species does not tell a reader where the water came from, how big the growth was or when it started; your photos, measurements and dates do.[6]
If a licensed assessor samples the air or a surface as part of a Florida mold assessment, keep the report. It belongs in Additional Documentation, alongside moisture readings and the assessor’s written findings, as supporting material rather than as the record itself.[1]
Who may assess or remove mold in Florida, and what their paperwork gives you
Florida licenses mold-related services. As published by the Florida Senate (2025 text), section 468.8411 defines a mold assessment as a process performed by a mold assessor that includes the physical sampling and detailed evaluation of data obtained from a building history and inspection to formulate an initial hypothesis about the origin, identity, location, and extent of amplification of mold growth of greater than 10 square feet. It defines mold remediation as the removal, cleaning, sanitizing, demolition, or other treatment, including preventive activities, of mold or mold-contaminated matter of greater than 10 square feet that was not purposely grown at that location. Read the current text; ClaimPrep does not interpret it.[1]
The same chapter usually keeps the two roles apart. Section 468.8419, as published by the Florida Senate (2025 text), provides that a mold assessor may not perform or offer to perform any mold remediation to a structure on which the mold assessor or the mold assessor’s company provided a mold assessment within the last 12 months, and states that this paragraph does not apply to a certified contractor classified as a Division I contractor under section 489.105(3). Section 468.841 also lists exemptions, including a residential property owner who performs mold assessment or remediation on his or her own property and holders of several other professional licences. For your record this means noting who assessed, who remediated, whether they were the same company, and each licence number, which you can check on the Florida DBPR mold-related services page. Mold remediation contractors generally work to the ANSI/IICRC S520 standard for professional mold remediation; ask whether they follow it and keep whatever documentation they produce under it.[2][3][7][8]
- Assessor: company name, licence number, date of inspection, date of the written report, and what it says about origin, location and extent.
- Remediator: company name, licence number, the written scope of work, the start and finish dates, and any post-remediation verification they provide.
- Any restoration company drying the structure: their scope, moisture readings and invoices, kept with the mitigation log.
What to photograph and record for each patch
Each patch of growth gets the same set of photos: the room from the doorway with the patch visible, the patch with a tape measure across its longest dimension, the same across its widest, and a close-up of the surface. Then photograph the moisture evidence next to it: the stain, the swollen baseboard, the dripping fitting. The caption carries the room, the two measurements and the date.
| Photo | What is in the frame | Caption example |
|---|---|---|
| Room from the doorway | The whole wall or floor with the patch visible and a door or window for reference | Hall bathroom from door, growth behind toilet, 2026-06-02 08:15 |
| Length and width with tape | Tape measure across the longest, then the widest, dimension, reading legible | Hall bathroom wall, 30 by 25 cm, 2026-06-02 |
| Close-up | The surface texture and colour, no flash if it washes out the detail | Hall bathroom wall, close-up, 2026-06-02 |
| Moisture evidence | The leak, stain or condensation that explains the patch | Hall bathroom, supply line drip onto floor, 2026-06-02 |
| Hidden side, only if safe | Behind a loose baseboard, under a lifted carpet edge, back of a panel already off | Bedroom 2, behind baseboard, 2026-06-09, baseboard was already loose |
| Air handler and registers | Filter in place and removed, return grille, discoloured supply registers, drain pan | Air handler closet, filter removed, 2026-06-14, system off since 07:50 |
EPA lists the back side of drywall, wallpaper or panelling, the top side of ceiling tiles and the underside of carpets and pads as places where mold may be hidden, and warns that a contaminated HVAC system can spread mold through the building. Photograph hidden surfaces only when they are already exposed or can be lifted without disturbing growth, and treat the air handler and ducts as an affected area of their own, with the old filter kept in a dated bag if a technician replaces it. If a remediator opens a wall, be there with the camera; that view exists for one afternoon.[4]
Build the timeline and record the remediation before and after
The mold timeline runs from the moisture event to the post-remediation check. Keep what you observed, what you recorded and what you did in separate columns, one entry per change or visit, and write “unknown” where you do not know. Humidity readings from a household hygrometer, with the device named and the time noted, are worth a line each while the source is being fixed.
| Date and time | Observed | Recorded | Acted |
|---|---|---|---|
| Unknown, before 2026-05-20 | Supply line began to drip behind the toilet | Nothing | Nothing |
| 2026-06-02 08:15 | Growth on the wall behind the toilet, 30 by 25 cm | Photo set with tape, humidity 68% on the hallway hygrometer at 08:20 | Closed the supply valve at 08:25; plumber replaced the line next day, invoice 5120 |
| 2026-06-11 10:00 | Licensed assessor inspected both rooms and the air handler | Licence number, report dated 2026-06-13 | Nothing |
| 2026-06-18 to 2026-06-20 | Remediation company removed lower drywall in both rooms | Same-wall photos before, during and after; scope of work; licence number | Paid invoice 7702 |
Photograph the same wall from the same spot on the day before remediation starts and on the day it finishes. Three photos of one wall with three dates say more than thirty photos of thirty things. Keep the remediator’s completion paperwork with the after photos.
Inventory, receipts and where each document goes in the record
EPA notes that absorbent or porous materials, such as ceiling tiles and carpet, may have to be thrown away if they become moldy. Anything that leaves the house because of mold gets a row in your inventory first: the item, the room, its condition, the purchase date and price where known, a photo in place and the discard date. Hard items that are cleaned and kept get a photo before and after.[4][5]
| Document | Report section |
|---|---|
| Photos of each patch with tape, dated and captioned | Photo Documentation |
| Source, first-seen and size table, one row per room | Affected Areas and Timeline |
| Assessor’s report, lab results, moisture and humidity readings | Additional Documentation, with the licence number and report date also in the Timeline |
| Remediation scope, start and finish dates, completion documents, before and after photos | Mitigation Actions |
| Plumber, HVAC, assessor and remediator invoices, kept apart from rebuild estimates | Additional Documentation |
| Items discarded because of growth, photographed in place | Detailed Documentation |
Keep the original photo files with their capture dates, keep the old supply line or fitting that caused the moisture in a labelled bag, and write the room on every receipt as you file it. An estimate for rebuilding a bathroom is a prediction; the remediator’s invoice is a payment.
What to document
| Item | Why it matters | Where it appears in your report |
|---|---|---|
| Moisture source identified, photographed and dated, or written as “unknown” with the last known dry date | Mold is documented as a consequence of moisture | Damage Summary |
| First-seen date for growth recorded separately for each room | Fixes the sequence from moisture event to spread | Timeline of Events |
| Length and width of every patch photographed with a tape measure, dimensions in the caption | Extent is measured, not estimated; Florida’s statutory definitions and EPA’s guidance both use a 10 square foot figure | Photo Documentation |
| Hidden-side photos behind loose baseboards or under lifted carpet edges, taken only where already exposed | EPA lists these as places mold hides; the photo exists only while the surface is open | Affected Areas |
| Air handler filter, drain pan and supply registers photographed and the last-run date noted | The HVAC system is its own affected area | Affected Areas |
| Mold assessor’s licence number, inspection date and report date logged | When a licensed assessor is involved, the report is the professional view of origin and extent | Additional Documentation |
| Same-wall photos on the day before remediation, during and after completion | Shows what was removed and what the wall looks like now | Mitigation Actions |
| Humidity and moisture readings written with the device used, the location and the time | A reading without a location and time is not evidence | Documented Details |
| Carpet, ceiling tile, drywall and furniture removed because of growth photographed and listed before disposal | EPA notes porous materials may have to be thrown away; the list is what remains | Detailed Documentation |
| Remediator’s licence number, scope of work and start and finish dates kept with the invoice | Assessment and remediation paperwork both belong in the record, whoever produced them | Additional Documentation |

Who to contact
- A Florida-licensed mold assessor
- Florida defines mold assessment of growth over 10 square feet as a licensed activity, with exemptions the statute lists; an assessor’s report describes origin, location and extent, and the licence number goes in your record.[1][3]
- A Florida-licensed mold remediator
- Florida generally keeps assessment and remediation of the same structure apart for 12 months, with a statutory exception for Division I certified contractors; record who remediated, their licence number, scope, dates and completion paperwork.[2][8]
- A licensed plumber, roofer or HVAC technician
- Whoever fixes the moisture source; ask for a written note naming the cause and the date, and keep the failed part.[5]
- Your insurance company or agent
- They receive notice of the loss and explain their own process; note the date and the name of the person you spoke to in your timeline.
Common documentation mistakes
- Paying for a lab test before anyone has found the moisture source
- Record the source, the first-seen date and the measured extent first; CDC does not recommend mold testing, and a species name does not date or locate the water.
- Writing “mold in the bathroom” without a size
- Photograph a tape measure across the length and the width of every patch and put both numbers in the caption.
- Scraping or pulling material away to photograph what is behind it
- Photograph hidden sides only where they are already exposed, and leave larger growth to someone equipped for it.
- Not recording who assessed and who remediated
- Florida generally separates the two roles for 12 months, with a statutory exception for Division I certified contractors; log each company and licence number so the record shows who did what.
Questions
Do I need a lab test to document mold?
CDC does not recommend mold testing and says that if mold is growing in your home you need to clean it up and fix the moisture problem. For documentation, the record that matters is the moisture source, the date growth was first seen in each room, the measured size of each patch and the before and after photos of remediation. If a licensed assessor takes samples as part of an assessment, keep the report as supporting material.[6]
How does Florida license mold assessors and remediators?
Florida’s mold-related services statute, as published by the Florida Senate (2025 text), defines mold assessment and mold remediation as activities involving growth of greater than 10 square feet and licenses both, with exemptions in section 468.841 that include a residential property owner working on his or her own property and holders of several other professional licences. An assessor generally may not remediate a structure their company assessed within the last 12 months; the statute excepts Division I certified contractors. Licence numbers can be checked with the Florida Department of Business and Professional Regulation. Read the current statute; ClaimPrep does not interpret it.[1][2][3][8]
How do I show when the mold started?
You usually cannot show the exact day, so record what you can: the date of the moisture event if known, the last date you are sure the surface was clean, and the date you first saw growth in each room, with a photo and a measurement for that day. Any older dated photo of the same wall while it was clean is the start of the timeline. Write “unknown” where you do not know rather than guessing.
Where do moisture readings and assessment reports go in the report?
In Additional Documentation, as supporting material alongside the invoices. The assessor’s licence number and report date also go into the Timeline as an entry for the inspection, and the remediation scope with its start and finish dates goes to Mitigation Actions with the before and after photos of the same wall. Each reading should name the device, the location and the time.
