Mold Remediation Orlando
Orlando's Mold Problem
Starts in the Foundation
Mold in an Orlando home usually traces back to two things: humidity that never really lets up, and water that got in and was never fully dried. After a wet season that drops around 50 inches of rain, or a slab that wicked up flood water during Hurricane Ian in 2022, mold can be established behind the drywall long before anyone smells it. We contain it, remove it, treat the HVAC and seal the water source in one project.

What is mold remediation?
Mold remediation is the process of removing mold and fixing the moisture that caused it. A licensed remediator contains the area, removes mold-damaged materials like drywall and insulation, treats the surfaces, and dries the structure so the mold cannot return. In Florida it requires a state license.
Why mold spreads fast in Orlando homes
Mold does not need a flood in Orlando, it just needs a few warm humid days, and this is one of the most humid metros in the country. Average humidity sits around 74% and climbs past 90% through the summer, so the moment water gets into a wall or an air handler sweats onto a duct, mold has what it needs. Florida sees mold appear within 24 to 48 hours of moisture, faster than almost anywhere else in the country.
What makes Orlando specific is the housing. Most homes here are concrete block on a slab, built from the 1960s through the 1990s. Block holds moisture against the inside of the wall, and central air systems push spores through the duct work into every room. After Hurricane Ian flooded west Orange County in 2022, the mold calls did not come during the storm, they came weeks later, once the trapped moisture in those block walls had time to feed. That is why we treat the HVAC and the wall cavity, not just the surface you can see.

What Makes Orlando's Mold Problem Different
The Wet Season Never Really Stops
Orange County gets more than 50 inches of rain a year, most of it falling in afternoon storms between June and September. In neighborhoods like Dr. Phillips, Metro West and Windermere, the terrain sits low and the water table can reach as close as two to five feet below grade. Sand Lake Road and Apopka-Vineland Road flood because the ground cannot absorb the volume fast enough. That same water pressure presses against the foundation walls of every home around them.
Two Named Storms Left Orlando Playing Catch-Up
Hurricane Ian (September 2022) brought heavy rainfall across Orange County and left moisture behind walls in thousands of homes that homeowners did not find for months. Hurricane Milton (October 2024) moved directly across the I-4 corridor, spawning tornadoes in Orange County and flooding Dr. Phillips and Metro West again. Homes that were not fully dried out after either storm are still developing secondary mold growth. Florida's year-round heat and humidity mean that once water gets in, mold can begin growing within 24 to 48 hours. There is no cold season that slows it down.
Older Homes, a Broken Insurance Market
The ranch homes throughout Ocoee, the original Metro West subdivisions and the older sections of Winter Garden were built in the 1970s and 1980s, before Florida adopted modern moisture barrier requirements. Concrete block construction was standard and most of those homes have no interior drainage system and no vapor barrier in the crawl space. Florida's insurance crisis is now pushing Orange County homeowners into Citizens Insurance or out of coverage entirely. A documented mold claim can trigger non-renewal. For homeowners in these older neighborhoods, fixing the water source before a claim is filed protects both the house and the policy.
Why Orlando homes grow mold
Orlando's building stock works against you here. The concrete-block, slab-on-grade homes that fill the 1960s-to-1990s neighborhoods trap humidity in their wall cavities, and there is no basement to inspect, just slab and wall space where moisture sits. Air conditioners run hard for most of the year and sweat inside the ductwork, feeding mold from the inside. In the Metro West and Dr. Phillips corridors, the heavier clay soil holds water against the foundation instead of letting it drain. Florida consistently ranks among the top states for mold-related health complaints, and homes across Orange County that flooded during Hurricane Ian in 2022 are still surfacing growth that surface drying missed.
Our Process
Six Steps to a Mold-Free Home in Orlando
Inspection and Air Quality Testing
We start with a full visual inspection and test air quality for spore counts. In Orlando's CBS homes, we check behind wall cavities, inside crawl spaces and along the perimeter of slab edges, where water most commonly enters concrete block construction. We open and read the block wall cavities where Central Florida homes hold the moisture the surface hides. You get a written report of what we find before any work begins.
Containment
Before any removal starts, we seal off the affected area with negative air pressure barriers. This keeps spores from spreading to clean areas of your home while work is in progress. Containment is not optional. Skipping it turns a contained problem into a whole-house problem.
Removal and Surface Treatment
We remove all mold-affected material, then treat exposed surfaces with EPA-approved fungicidal solution. We do not spray over mold or encapsulate without removing it. Everything that is contaminated comes out.
HVAC and Duct Treatment
Mold spores travel through your air system and settle in duct work. We replace your HVAC filter and fog antifungal vapor through the ducts to kill airborne spores at the source. We seal off and treat the HVAC system, since Orlando's central-air homes carry spores duct to duct into rooms that never got wet. Most mold companies skip this step. We include it because incomplete remediation is not remediation.
Waterproof the Entry Point
This is what separates Bullfrog from every other mold company in Orlando. Once the mold is out, we waterproof the foundation entry point that let moisture in. Without closing the source, mold will come back. We hold Florida mold remediator license MRSR5565 and we do the waterproofing in the same project, so you do not need to hire a second contractor and coordinate two separate scopes of work. If water damage has occurred, we also offer water damage restoration in Orlando.
Post-Remediation Clearance Testing
After the job is complete, we test air quality again. Spore counts must return to normal outdoor levels before we consider the project done. You receive a written clearance report that documents the before and after readings.
One Company. Mold Out. Water Stopped. Warranty Backed.
Every other mold remediation company in Orlando will clean up what is there. We do that. But we also close the path water used to get in. Bullfrog holds Florida mold remediator license MRSR5565 and performs full foundation waterproofing under the same contract. That means one crew, one project and one warranty. The moisture that caused the mold is gone for good, not just cleaned up until the next wet season.
