Mold Inspection Orlando

Most Orlando Homes With Mold
Don't Smell Like It Until It's Already Spread.

Mold can grow for months inside a concrete-block wall cavity or an AC duct with nothing visible on the surface, so a musty smell you cannot trace usually means it has already spread. An inspection tells you what is actually there before it turns into a bigger bill. We walk the whole home, take moisture readings on the walls that look fine and hand you written findings.

What does a mold inspection include?

In an Orlando block home, mold detection comes down to the walls, so the free inspection is built around them. We go through the whole house, follow any musty smell and put a moisture meter on the painted block that looks clean as well as the stained patches, because a block wall can soak up water from the slab and still look fine from inside the room. The written findings are yours to keep. Air samples and lab results cost extra and come from a licensed mold assessor.

What Hides in Orlando Homes After the Storm Season

Hidden Moisture After Milton and Ian

Hurricane Milton crossed the I-4 corridor in October 2024 and dropped heavy rain across Orange County, flooding Dr. Phillips, Metro West and parts of southwest Orange County. Hurricane Ian did the same in September 2022. After both storms, plenty of homes looked structurally sound. Walls were dry to the touch, no visible staining. But moisture had worked into block wall cavities, under flooring and behind bathroom tile, and by the time the smell appeared months later, the mold colony was already established. Moisture readings on walls that look dry find that trapped water before the mold shows on the surface. Our Orlando storm watch tracks the alerts and rainfall that start this pattern.

Real Estate Transactions and Insurance Triggers

Finding mold at closing kills deals. Finding it after closing creates legal exposure for the seller under Florida's disclosure requirements. Buyers in Orange County are increasingly requesting mold inspections as a condition of sale in older neighborhoods, and some lenders are requiring them outright on homes with a prior flood or water loss on record. A documented mold claim that predates your current policy can be denied as a pre-existing condition. A written inspection report before you buy, sell or file a claim puts the facts on record.

CBS Construction Hides Mold for Months

The concrete block and stucco homes in Dr. Phillips, Metro West, Ocoee and the older sections of Winter Garden were the standard build in Orange County from the 1970s through the early 2000s. CBS walls hold moisture inside the block cavity without showing it on the surface. Wood framing swells and stains when wet. Block just sits there while the mold grows on the inside face of the wall. By the time discoloration appears on the drywall or the paint starts to bubble, the colony has been growing for weeks or months. Moisture readings on the inside of the wall pick up the water in the block before any of that shows up.

What an Orlando mold inspection looks for

In Orlando homes, mold hides where the construction hides moisture: inside concrete-block wall cavities and up in the AC ductwork, neither of which shows anything from the living space. Two situations bring us out most often. The first is a fast home purchase, common in the Orlando market, where nobody checked for moisture before closing. The second is a home that flooded during the 2022 storm season across Metro West and Orange County, got dried on the surface and was closed back up with moisture still trapped in the slab and walls. Moisture readings find the water a walk-through by eye would miss.

Our Inspection Process

What We Check During a Free Mold Inspection in Orlando

  1. Whole-Property Walk-Through

    A stain in the hallway can start at a slab joint two rooms away, so we go into every room. Our list: foundation walls and slab edges, plumbing below every sink, the HVAC system and its closet, the roof and every window, plus the crawl space on the rare Orlando house that has one. In Orange County's CBS homes, we pay particular attention to block wall cavities and the exterior grade line, where water builds against the foundation during wet season and after storms.
  2. Moisture Mapping

    We use a moisture meter to map readings across walls, floors and ceilings. Elevated readings in areas that look dry on the surface indicate water intrusion that has not yet caused visible damage. Those readings lead us back to where the water is getting in.
  3. A Check for Smell

    A mildew smell in a closed bedroom or in a closet on an outside wall tells us a lot. Florida's Department of Health says indoor mold growth can usually be seen or smelled, so a smell with no stain to match is where the meter goes next.
  4. When You Need Lab Testing

    Air samples, swabs and lab work sit outside our visit. In Florida, sampling is the first step of a regulated mold assessment and needs a licensed mold assessor, who charges for it separately. It pays off in a dispute over whether mold is present. It also helps when you think there is mold but can find no sign of it and when someone in the home is allergic to a particular mold. Where the mold is already visible, EPA guidance is that you usually do not need to sample it. Our guide on how to test for mold sorts the useful tests from the rest.
  5. Written Findings You Keep

    The report lists each reading, the rooms affected and what we would do about them. It is yours to keep even if you never call us again and it is the document an insurer, a lender or a real estate agent will ask to see.
  6. A Plan to Fix the Water and Any Mold

    When the walls are wet, the free estimate shows in writing how we would seal the block, dry it out and take out any mold. What a free mold inspection includes sets out the visit in full. Mold removal, duct treatment and foundation waterproofing all come from us under Florida mold remediator license MRSR5565, so you never have to hire a second contractor. See our full mold remediation process for Orlando homes for details. For the wider area, see waterproofing and mold remediation in Orlando. We offer the same mold inspection service across Florida.

The Inspector Who Can Also Fix It

A licensed mold assessor who samples your home may not remediate it for the next 12 months and that bar covers their company too (s. 468.8419). A sampled assessment therefore tends to end with a referral. Because we take no samples, our free inspection is not an assessment. We give you written findings and, if mold is found, we fix the problem under the same contract. Bullfrog holds Florida mold remediator license MRSR5565 and performs full remediation and foundation waterproofing in the same project. One crew, one timeline, one warranty. For Orange County homeowners dealing with hurricane damage, real estate timelines or insurance documentation needs, that means a single call handles the inspection, the remediation and the waterproofing. Start to finish.

Mold Inspection in Orlando: Frequently Asked Questions

How much does a mold inspection cost in Orlando?

It is free to any Orlando homeowner or property owner. We walk the whole house, map the moisture in the block walls and leave written findings and you are not obliged to use our services afterwards. Air sampling and lab results are a separate paid service from a licensed mold assessor and the bill depends on the size of the house, the number of samples the job calls for and the lab charge on each. Get that quote in writing first. If we find something to fix, our written estimate comes before any work starts.

Should I get a mold inspection before buying a home in Orlando?

Yes, especially given how fast the Orlando market moves and how much water some homes took on during the 2022 storm season. A pre-purchase inspection with moisture mapping protects you from inheriting hidden mold in the wall cavities and gives you leverage in the deal.

What does a mold inspection include?

It covers the whole house, with the block walls getting most of the attention. We take moisture readings on clean walls and stained ones, follow any musty smell to its source and write up what we find for you to keep. If water is getting in, the estimate includes a plan to stop it. Lab work is not part of it. A licensed mold assessor does air sampling for a fee and it is useful in a dispute over whether mold is present, when nothing is visible but you still suspect it or when someone at home is allergic to a particular mold.

My Orlando home was dried out after a flood. Do I still need an inspection?

Often yes. Surface drying misses moisture trapped inside concrete-block wall cavities and under the slab. An inspection with moisture readings confirms whether the structure is genuinely dry or quietly growing mold behind the drywall.

Can I test for mold myself?

DIY mold test kits from hardware stores detect whether mold spores are present in your home, which is almost always true to some degree. What they cannot tell you is whether indoor concentrations are elevated compared to outdoor baseline levels, which species are present, or where the moisture source is. Without those three answers, you cannot decide whether remediation is needed or where to start. Our free inspection answers the third by finding where the water is getting in. For the first two you need a licensed mold assessor, who sends samples to a lab and charges for it.
