What Florida homeowners should do after a hurricane before rebuilding: document damage, verify materials are dry and test for mold before new walls go up.

The hurricane has passed, the roof has a tarp on it and a contractor has given you a quote to put everything back the way it was. Before that first sheet of new drywall goes up, there is a step most homeowners skip, and it is the one that determines whether the repair holds or whether you reopen the same walls a year later because of a musty smell.
Rebuilding over wet or contaminated materials is the most common way a storm turns into a long-term mold problem in Florida homes. This post walks through what to do between "the storm is over" and "the rebuild begins."
The direct answer
Do not rebuild until the structure has been verified dry with instruments, not by appearance, and until any materials that supported mold growth have been identified and removed under a written protocol. Document everything first. The order matters: document, dry, assess, remediate if needed, verify, then rebuild.
Step 1: Document before you disturb anything
Your insurance claim, any contractor dispute and any future sale of the house all rely on a clear record of what the storm did. Before moving debris or pulling materials:
- Photograph every room from the doorway, then each wall, ceiling and floor.
- Photograph the exterior, roof, soffits, windows and any visible water lines.
- Note the date and time water entered, if you know it, and when it stopped.
- Keep receipts for tarps, fans, dehumidifiers and emergency services.
- Write down how long the home was without power or air conditioning.
That last item matters more than most people realize. A house that took on little or no water but sat closed in August heat for five days without AC can have humidity-driven growth on contents and in closets with no visible leak at all.
Step 2: Separate "wet" from "water damaged"
Not everything that got wet is a loss, and not everything that looks fine is dry. The 24 to 48 hour window is the dividing line: materials that were dried within that window often recover, while materials that stayed wet longer can support mold growth and usually need evaluation.
| Material | Dried within 48 hours | Wet longer than 48 hours |
|---|---|---|
| Painted drywall | Often salvageable if studs are dry | Typically removed to above the water line |
| Carpet and padding | Carpet sometimes, padding rarely | Both usually removed |
| Wood framing | Dries with airflow, verify with meter | Can be dried but needs testing for surface growth |
| Fiberglass batt insulation | Rarely dries evenly, often replaced | Replace |
| Tile on slab | Fine, check grout and underlayment | Fine, but check adjacent drywall |
| Cabinets (particleboard) | Often swell, inspect toe kicks | Usually replaced |
Tile floors on a slab are a Florida advantage here, but the drywall and baseboards around them are not. Water that pooled on tile for a day has usually been pulled up into the bottom of every wall in the room.
Step 3: Dry the structure, then prove it
Air movement and dehumidification are the tools. Fans alone in a humid Florida house move moist air around without removing it. If you have power, run the air conditioning continuously and add a dehumidifier in the wettest area. If you do not, prioritize removing saturated materials rather than trying to dry them in place.
"Proving it" means readings, not touch. Pinless moisture meters read through drywall and compare against a dry reference area in the same house. Thermal imaging shows cooler, evaporating areas that mark hidden moisture behind finished surfaces. These are the same tools used in a UES water intrusion and damage assessment, and the readings become part of your documentation.
Typical places hidden moisture survives after a hurricane:
- Behind baseboards and inside the bottom wall cavity
- Under window sills where wind-driven rain entered the frame
- In attic insulation beneath a tarped or patched roof
- Inside exterior block walls behind furring strips and drywall
- Under vinyl plank or laminate flooring laid over a slab
- Behind kitchen and bathroom cabinets along exterior walls
Step 4: Assess for mold before closing anything
If any area was wet beyond the 48 hour window, or if you cannot confirm when it dried, a mold assessment before the rebuild answers two questions: is there growth, and how far does it extend. A comprehensive mold assessment combines the visual inspection with air and surface sampling sent under chain of custody to an independent accredited lab. Results and a written remediation protocol are delivered through the UES Client Portal, which your contractor can reference directly.
The protocol tells the remediator exactly what to remove, how far beyond visible growth to cut, what containment to use and what the finished condition should look like. Without it, a general contractor is guessing, and the typical guess is "cut out the stained part and spray something."
Step 5: Remediate under the protocol, then verify
If remediation is needed, it should be done by a Florida-licensed mold remediator working from the written protocol. UES does not perform remediation and does not accept referral fees from contractors, so the protocol is written around what the building needs, not what a particular company sells.
Once the remediator finishes, a post-remediation verification visit confirms the work: the area is dry, visible growth is gone, and air sampling inside the containment is comparable to outdoor and unaffected indoor areas. Only after a passing PRV should the walls be closed. Think of it as the inspection you would want before paying the final draw.
Step 6: Rebuild with the next storm in mind
Hurricane repairs are an opportunity to make the house more forgiving the next time.
- Replace paper-faced drywall in the lowest 2 feet of exterior walls with moisture-tolerant board where codes and your contractor allow.
- Use closed-cell or rigid insulation at the base of walls instead of fiberglass batts that hold water.
- Seal penetrations and window frames properly during the rebuild rather than relying on exterior caulk alone.
- Add a dedicated dehumidifier or confirm your air conditioner is sized for humidity control, not just temperature.
- Keep a copy of the assessment, protocol and PRV report. Future buyers and insurers will ask.
Mistakes we see on post-hurricane rebuilds
- Using a "free" mold inspection from the remediation company. The findings and the quote come from the same pocket.
- Encapsulating instead of removing. Painting or coating over growth on framing is not remediation.
- Skipping the attic. Ceilings dry quickly, insulation does not.
- Trusting a dry-looking slab. Vapor coming through the slab after a flood keeps new flooring damp from below.
- Rebuilding on a schedule set by the contractor's availability rather than the building's moisture readings.
When to call UES
Call before the rebuild starts, especially if materials were wet more than 48 hours, if the home was without air conditioning for several days, or if a contractor's quote does not mention moisture readings or testing. We serve Orlando, Kissimmee, Tampa, Daytona Beach and all of Florida.
Book an assessment online or call (407) 438-4684, Monday through Friday, 9:00 AM to 5:30 PM.

Frequently asked questions
Should I test for mold before or after the contractor repairs storm damage?
Before. Once new drywall, insulation and flooring are installed, any moisture or growth left behind is sealed in and will have to be opened up again later. An assessment before rebuilding confirms the structure is dry and identifies any materials that need to come out first.
My walls look dry. Do I still need moisture testing after a hurricane?
Drywall often feels and looks dry while the studs, insulation and the back side of the board remain wet. Moisture meters and thermal imaging can see what the surface hides. If the home was without air conditioning for days or took on any water, testing is worth doing.
Can I use the same company to test for mold and to remove it?
In Florida, mold assessors and mold remediators are licensed separately, and the law is designed to keep those roles independent. Using an assessor who does not remediate means the findings are not tied to the cost of the repair work.
