Investigate Indoor Conditions With Better Information
A measured approach to visible mold conditions, moisture indicators, airborne particulate levels, sampling decisions, and clear laboratory documentation.
Different Conditions, Different Questions
Mold assessment and Advanced Indoor Air Quality testing evaluate different indoor conditions. Each service is scoped and priced separately so the testing matches the concern instead of treating every indoor-air-quality question as the same problem.
Advanced Indoor Air Quality Testing
Evaluate airborne particulate levels. Mold analysis is separate and must be specifically requested.
Explore Advanced IAQ testingMold Indoor Air Quality Testing
Mold Indoor Air Quality Testing evaluates airborne mold-spore conditions and requires an outdoor control sample for comparison. Indoor sampling locations are selected to address the reported concern and conditions observed.
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.
Mold Assessment
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.
Visible Mold Assessment
A focused assessment of a reported or visible concern and the accessible surrounding area, including relevant moisture observations and documented limitations.
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.
Advanced Indoor Air Quality Testing
Mold Indoor Air Quality Testing evaluates airborne mold-spore conditions and requires an outdoor control sample for comparison.
Advanced Indoor Air Quality Testing evaluates the types and levels of airborne particulates present inside the home. It is intended to identify construction-related debris, fibers, allergens, dust, and other particulates. Mold analysis is separate and must be specifically ordered.

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.
When Advanced IAQ testing may be useful
- Newly constructed homes
- Recently renovated homes
- Post-construction cleanliness evaluations
- Homes with excessive dust or poor housekeeping
- Evaluating airborne debris when visible mold conditions are not present
- Clients requesting a more thorough evaluation of indoor environmental conditions
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.
FHA/VA Water Sampling
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.
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.
