Mold Assessments Backed by Decades of Home Inspection Experience
With more than 20 years of experience inspecting South Florida homes, I bring an understanding of building construction, roofing, plumbing, air-conditioning systems, and moisture intrusion to every mold assessment I perform.
Mold concerns aren't always just about what's growing on a wall or appearing in an air sample. Understanding how moisture enters a building, how HVAC systems affect indoor conditions, and what may be contributing to mold growth is just as important as the testing itself.
As a Florida Licensed Mold Assessor, I combine that building knowledge with professional mold assessments, laboratory testing, and Advanced Indoor Air Quality testing to help clients understand their property's indoor environmental conditions and determine the appropriate next steps.

Environmental Services & Testing are available as standalone services, whether or not you're scheduling a home inspection.
My decades of experience inspecting South Florida homes provide additional insight into building construction, moisture intrusion, HVAC systems, and other conditions that can influence environmental assessments and testing.
Mold Assessments & Mold Indoor Air Quality Testing
Beacon provides mold assessments, airborne mold-spore testing, and surface sampling for homeowners, homebuyers, property managers, and real estate professionals throughout South Florida.
Whether you're concerned about visible mold growth, previous water intrusion, musty odors, or unexplained moisture conditions, my experience as a home inspector helps me evaluate the building systems that may be contributing to the problem.
Mold air sampling can help identify airborne fungal spores and provide laboratory results comparing indoor conditions with an outdoor control sample. Depending on the circumstances, targeted surface sampling and additional moisture evaluation may also be appropriate.
From limited assessments of specific concerns to comprehensive mold assessments, the testing and evaluation are selected according to the property's conditions and the client's needs.
Assessment Types and Sampling Options
Mold assessment begins with the property history, reported concerns, visible conditions, accessible areas, moisture observations, and conditions conducive to mold growth. Beacon agrees on the assessment scope before work begins.
Full Mold Assessment
A broader assessment of accessible areas within the agreed property scope, considering the property history, visible conditions, moisture indicators, and conditions conducive to mold growth. Inaccessible or concealed areas remain subject to the agreed limitations.
Visual and moisture assessment
Document visible growth, water intrusion, staining, elevated moisture, and conditions conducive to mold growth in accessible areas.
Targeted sampling
Sampling may be recommended when it can help define or document the concern. It is not automatically required at every property. Depending on the conditions, sampling may include indoor air, surface, or wall-cavity locations.
Mold air sampling
Collect air samples at selected indoor locations for mold analysis. Indoor results are evaluated against a separate outdoor control sample collected at the time of testing.
Surface sampling
Collect material from a selected surface to help document the concern at that location. Surface sampling is different from testing the indoor air.
Wall-cavity sampling
Sample a selected wall-cavity location when the conditions and access support that approach. Locations and access requirements are agreed before sampling.
Sampling Coverage
For service-planning purposes, each indoor air sample is generally intended to represent approximately 800 square feet of reasonably open air space.
Square footage alone does not determine the number of samples needed. The layout of the home, number of rooms, closed or separated areas, hallways, HVAC zones, and normal airflow patterns may require additional sampling locations for more complete coverage.
For example, a mostly open 1,600-square-foot home may be reasonably represented by two indoor sampling locations. A 1,600-square-foot home with multiple bedrooms, hallways, closed rooms, or separated air spaces may require additional samples to provide comparable coverage.
We offer both:
Complete-Coverage Sampling
Sampling locations are selected to reasonably represent the separate air spaces throughout the home based on square footage, layout, room separation, HVAC zoning, and airflow.
Limited / General-Conditions Sampling
A smaller number of samples may be collected to provide a broader snapshot of general indoor conditions. Limited sampling does not evaluate every individual room or isolated air space.
Mold Spores & Fungal Structures Identified
Mold spores and fungal structures that may be identified by laboratory analysis include, but are not limited to:
Aspergillus/Penicillium
Stachybotrys
Chaetomium
Cladosporium
Alternaria
Curvularia
Epicoccum
Basidiospores
Ascospores
Other identifiable fungal types reported by the laboratory
Outdoor control sample: Mold air testing requires a separate outdoor control sample so indoor results can be evaluated against outdoor conditions at the time of testing.
Mold sampling starts at $125 per sample
The final price depends on the assessment scope, number and type of samples, property location, and access conditions. The per-sample starting price is not a flat price for a Visible Mold Assessment or Full Mold Assessment.
Advanced Indoor Air Quality Testing
Advanced Indoor Air Quality testing goes beyond traditional mold-spore analysis by examining a broader range of airborne particulates that may affect indoor environmental conditions.
Laboratory analysis can identify particulates such as:
- Fiberglass and insulation fibers: Materials that may originate from insulation, ductwork, or building components.
- Drywall and construction dust: Gypsum debris, mineral particles, and other materials associated with construction or renovation.
- Dust mites and insect fragments: Common indoor allergens and biological debris.
- Pet dander and skin-cell debris: Particles associated with pets and normal indoor activities.
- Pollen and plant particles: Outdoor allergens that can enter the indoor environment.
- Soot and combustion-related particles: Materials potentially associated with smoke, combustion, or other sources.
Advanced Indoor Air Quality testing can be valuable in newly constructed homes, recently renovated properties, homes with excessive airborne dust, and properties where occupants have concerns about indoor environmental conditions.
Advanced Indoor Air Quality testing can also be combined with mold air sampling, providing a broader evaluation of airborne particulates and fungal spores through coordinated testing.
Combining these services may be particularly useful when investigating moisture concerns, aging HVAC systems, indoor dust, or conditions that are not fully explained by mold testing alone.
Sampling Coverage
For service-planning purposes, each Advanced Indoor Air Quality sampling location is generally intended to represent approximately 800 square feet of reasonably open air space.
Actual coverage depends on the layout of the home. Rooms, walls, hallways, closed doors, separate HVAC zones, and isolated air spaces can affect how representative a sample is of surrounding areas.
For example, two sampling locations may provide reasonable coverage of a mostly open 1,600-square-foot home, while the same square footage divided into numerous separate rooms may require additional sampling locations for more complete evaluation.
We offer both:
Complete-Coverage Advanced IAQ Testing
Sampling locations are selected to reasonably represent the separate areas of the home based on square footage, layout, HVAC zoning, and airflow.
Limited / General-Conditions Advanced IAQ Testing
A smaller number of samples may be used to provide an overall snapshot of general airborne conditions. Limited testing should not be interpreted as evaluating every individual room or isolated air space.

Advanced Indoor Air Quality Testing for New Construction
A newly constructed home can look spotless while still containing airborne dust and particulates left behind by the construction and finishing process.
Drywall work, insulation, flooring installation, cabinetry, cutting, sanding, painting and other construction activities can introduce fine particles into the indoor environment. Construction debris and dust may also remain within occupied areas or HVAC components even after the home has received its final cleaning.
Some newly installed building materials, coatings, adhesives and finishes may also release chemical compounds. Beacon’s Advanced Indoor Air Quality particulate analysis evaluates particles captured in the submitted air samples; it does not measure VOCs or other gases. Chemical testing, when appropriate, requires a separately specified analysis.
Advanced Indoor Air Quality testing before occupancy can provide buyers with an objective pre-occupancy baseline before furnishings, pets, cleaning products and normal household activities begin influencing the indoor environment.
If testing identifies elevated particulate conditions, the findings may help identify conditions or areas that should receive additional evaluation or attention before move-in. Depending on the findings, this may include additional cleaning, ventilation, HVAC-related attention, removal of construction debris or dust, or further evaluation by the builder or appropriate contractor.
Addressing identified conditions before occupancy may also give the buyer an opportunity to raise those concerns while the builder and subcontractors are still involved with the property.
A new home should not just look clean. It should start with a clean indoor environment.
Mold Testing for New Construction
New construction can also experience moisture exposure long before the homeowner takes possession. Lumber, roof decking, drywall, insulation and other building materials may be exposed to rain or elevated humidity during construction. Plumbing leaks, incomplete building-envelope protection and other construction-related moisture conditions may also occur before the home is fully dried in and climate controlled.
When building materials remain damp for an extended period, conditions may develop that warrant further evaluation for possible microbial growth, even when the completed home appears clean.
For buyers who want microbial screening in addition to Advanced Indoor Air Quality particulate testing, mold analysis may be added to the new-construction testing scope.
When combined with Advanced Indoor Air Quality testing:
Mold analysis: +$25 per indoor sample
Added to the same Advanced IAQ sampling scope; not a standalone mold-testing price.
Required exterior mold control sample: +$125
The exterior control is required when mold air analysis is ordered so indoor findings can be evaluated with an outdoor comparison sample.
Together, Advanced Indoor Air Quality particulate testing and optional mold analysis can provide a broader pre-occupancy picture of conditions inside a newly constructed home while the builder and subcontractors are still available to address concerns that may be identified.
Advanced IAQ testing starting at $175
$175 per indoor sample
Advanced IAQ testing. Mold analysis is not included in this price.
Add mold analysis: $25
Add mold analysis at the same indoor sampling location when specifically ordered.
Outdoor mold control: $125
A separate outdoor mold control sample is required when mold analysis is ordered.
Pricing example: One indoor Advanced IAQ sample with mold analysis, plus the required outdoor mold control sample, totals $325. Each additional combined indoor sampling location is $200.
Advanced Indoor Air Quality Assessment
An assessment begins with the client’s concerns, property history, and observable indoor conditions to help define the questions that testing should address. The assessment scope and any proposed sampling are explained before work begins.
Assessment and laboratory testing are different parts of the process. Laboratory analysis applies to the samples specifically ordered and submitted. Mold analysis is separate, and Advanced IAQ does not determine whether asbestos is present or test for VOCs.
Private Well Water Sampling & FHA/VA Water Testing
Private well water quality is an important consideration for homeowners and buyers throughout western Palm Beach County and other rural areas of South Florida.
I've been performing private well water sampling for more than 15 years. Through that experience, I've encountered bacterial contamination concerns in older well systems, including positive results for total coliform bacteria and E. coli.
A private water supply may appear clear and operate normally while laboratory testing identifies water-quality concerns.
Beacon provides private well water sampling and laboratory testing for homebuyers, existing homeowners, and real estate transactions, including FHA and VA mortgage requirements when applicable.
Depending on the property's water supply and requested testing, laboratory analysis may include:
- Total coliform bacteria
- E. coli
- Nitrates and nitrites
- Additional water-quality parameters when appropriate
Whether you're purchasing a property with a private well, preparing for an FHA or VA transaction, or simply interested in the quality of your household water supply, professional sampling can provide useful information about the water you're using.
My experience inspecting rural properties also helps me recognize visible concerns involving pressure tanks, water-treatment equipment, plumbing installations, and other components associated with private well systems.
Transaction Requirements and Sampling Scope
Water sampling for an FHA or VA transaction is scoped around the testing requested for the property. Provide the lender’s water-testing requirements so the sampling and laboratory analysis can be arranged for the requested scope.
Beacon will explain the proposed sampling, laboratory documentation, and price before collection. Water sampling is separate from mold and Advanced IAQ services; laboratory results apply to the submitted water samples and are not a guarantee of loan approval.
Chinese Drywall Inspections & Testing
Although problematic imported drywall is not commonly encountered in South Florida homes today, some properties constructed or renovated during the mid-2000s may still contain suspect materials.
With my background in home inspections and building systems, I evaluate visible conditions that may indicate potentially problematic drywall, including unusual corrosion of copper piping, electrical components, and air-conditioning equipment.
When conditions warrant, additional testing can help determine whether suspect drywall materials are present and provide valuable information for buyers, homeowners, and property investors.
Home-inspection observations, not a separate Beacon testing service
Lead-Based Paint Concerns
Potential lead-based paint concerns may be considered during the normal home-inspection process based on the age of the property, visible materials, deterioration, peeling or damaged painted surfaces, and other observable conditions. When conditions warrant, the concern will be brought to the client’s attention.
A standard home inspection does not determine whether lead-based paint is present. Any dedicated lead assessment, sampling, laboratory testing, risk assessment, or clearance testing must be performed by an appropriately licensed or certified lead professional.
Further professional evaluation: Beacon does not offer lead assessment or testing. These observations identify concerns for evaluation by an appropriately licensed or certified lead professional; they do not confirm the presence of lead.
Home-inspection observations, not a separate Beacon testing service
Asbestos-Containing Material Concerns
Potential asbestos-containing materials may be considered during the normal home-inspection process based on the age of the property, visible building materials, alterations, deterioration, or evidence that potentially suspect materials have been disturbed. When conditions warrant, the concern will be brought to the client’s attention.
A standard home inspection and the Advanced Indoor Air Quality service do not determine whether asbestos is present. Any dedicated asbestos assessment, inspection, sampling, laboratory testing, air monitoring, or clearance testing must be performed by an appropriately licensed asbestos professional.
Further professional evaluation: Beacon does not offer asbestos assessment or testing. These observations identify concerns for evaluation by an appropriately licensed asbestos professional; they do not confirm the presence of asbestos.
Understand the Testing Limitations
- Advanced IAQ does not determine whether asbestos is present.
- Advanced IAQ does not test for volatile organic compounds (VOCs).
- Mold testing is separate unless specifically ordered.
- Laboratory results identify and quantify materials found in the submitted samples.
- Environmental testing is not a medical diagnosis or a guarantee concerning occupant health.
Choose Testing Based on the Condition
Beacon will explain the available testing options and prepare the sampling scope before testing begins. The objective is to select the appropriate service for the conditions observed and provide clear laboratory documentation of the submitted samples.
Based in West Palm Beach, Beacon offers environmental assessments and testing throughout Palm Beach County, Broward County, Martin County, and the existing South Florida and Treasure Coast service area.
