Pathways™ Testing in Orange County, Florida.

Why here

Why Pathways™ fits Orange County.

Three local conditions stack together in Orange County. First, the dominant residential building era is the late 1980s through the 2000s, when developers across Hunter's Creek, MetroWest, Avalon Park, Lake Nona, and the Apopka-Ocoee corridor adopted slab-on-grade construction with stucco-over-block exteriors and attic-mounted air handlers. That design is efficient until a flashing detail fails or a condensate drain backs up, at which point moisture has nowhere to go except into the framing or down through the attic floor.

Second, Orange County took meaningful wind-driven rain from Hurricane Ian in 2022 and again from Milton in 2024. Neither was the catastrophic storm-surge event the coastal counties absorbed, but both pushed water laterally into roof-to-wall transitions and gable-end penetrations across the I-4 corridor. Many of those intrusions were superficial enough to dry out without triggering a visible repair, leaving residual contamination inside the wall assemblies. Third, Central Florida summer dew points sit at 73°F to 76°F for months at a time, which means any latent moisture in those assemblies stays biologically active rather than drying down.

Pathways™ testing was built for exactly that combination. Conventional spore-trap air sampling in the middle of the bedroom will frequently come back “normal” in these homes because the contamination is in the assembly cavity, not in the room. Microfiber-swab sampling at the assembly's transition points is the methodology that surfaces the problem.

Local scenarios

Typical Pathways™ cases in Orange County.

• Avalon Park and Lake Nona tract homes after Ian (2022) or Milton (2024). Roof-to-wall transitions or gable-end vents took wind-driven rain, repairs were superficial, and the homeowner is now reporting symptoms that did not exist before the storm. Pathways™ targets the affected wall assemblies and the air-handler closet.
• Dr Phillips and Windermere custom homes with hidden condensate failures. Larger square footage often means two or three air handlers, frequently in attic mechanical rooms or interior chases. Long-running condensate drips into chase walls produce localised contamination that air sampling routinely misses.
• Winter Park and College Park older homes (pre-1970). Different building stock entirely: pier foundations, plaster walls, retrofit central HVAC squeezed into closets that were not designed for it. Pathways™ sampling at baseboard joints, original window perimeters, and the retrofit HVAC chase tells a much more honest story than ERMI alone.
• Apopka, Ocoee, and Winter Garden suburban tracts with CIRS or MCAS occupants. When a healthcare provider has flagged the indoor environment and HERTSMI-2 has come back elevated, Pathways™ identifies which assembly is the source so remediation can be surgical.
• Pre-purchase due diligence in Hunter's Creek and MetroWest. Homes from this era frequently carry undocumented water-loss history. A pre-close Pathways™ survey of the master closet, laundry, and primary-bath walls is a defensible way to find out what the seller's disclosure missed.

How it runs

How an Orange County Pathways™ visit runs.

Most Orange County work runs out of Orlando along the I-4, the 408, and the 417. A typical residential Pathways™ visit is scoped on the phone before any work is booked, so the sample count and project cost are known up front. On-site, Daniel grids the testable area into 500 sq ft zones, walks the home with a moisture meter and thermal camera to identify suspect assemblies, then runs the microfiber-swab protocol at thirty to fifty transition points per zone. Suburban single-family homes in Avalon Park, Hunter's Creek, or Winter Garden typically run a single half-day on site. Larger Dr Phillips or Windermere custom homes can run a full day. Swabs are sealed, chain-of-custody logged, and shipped same-day to the accredited Pathways™ lab. Lab turnaround is 7 to 14 business days, the written report follows within a few days of return.

FAQ

Orange County questions.

• Is Pathways™ testing worth it for an Orange County home that already had ERMI? Often yes. ERMI tells you what species are in the room dust. It does not tell you which wall, outlet, or transition is the source. For Orange County's typical attic-air-handler tract construction, the source is usually in the air-handler closet wall or a roof-to-wall transition. Pathways™ maps that.
• Do you cover Avalon Park, Hunter's Creek, and Dr Phillips? Yes, plus Lake Nona, MetroWest, Windermere, Dr Phillips, Apopka, Ocoee, Winter Garden, Winter Park, College Park, Audubon Park, Baldwin Park, downtown Orlando, and Conway. Most Orange County jobs scheduled within 48 hours.
• Still feeling sick after a post-Ian remediation, what now? Prototypical Orange County Pathways™ scenario. Pathways™ of the suspect rooms plus the air-handler closet typically identifies whether anything is still moving into living space.
