On average, air sampling can take anywhere from 30 minutes to a few hours.

Bulk Sampling

Bulk sampling involves collecting physical samples of materials suspected to have mold growth, such as pieces of drywall or carpet. These samples are then sent to the laboratory for analysis. The time required for bulk sampling depends on the number of samples collected and the complexity of the sampling process. Generally, bulk sampling can take anywhere from 15 minutes to an hour per sample.

Average Time Duration for a Mold Inspection

While the time duration for a mold inspection can vary depending on various factors, we can provide some averages to give you a better idea of what to expect. Keep in mind that these averages are general estimates and can vary from case to case.

Average Time for Small Properties

For small properties, such as single-room apartments or condominiums, a comprehensive mold inspection can typically be completed within a couple of hours. This includes the visual assessment, sample collection (if necessary), and initial reporting.

Average Time for Large Properties

For larger properties, such as multi-story houses or commercial buildings, the mold inspection process can take significantly longer. It may require several hours or even multiple days to thoroughly inspect each room, collect samples, and analyze the findings. The larger the property, the more time-consuming the inspection process becomes.

Residential vs Commercial properties

Residential properties, particularly single-family homes, tend to be smaller in size and generally require less time for a complete inspection compared to commercial properties. Commercial properties, such as office buildings or warehouses, often have larger areas to cover and may have complex HVAC systems or hidden areas that necessitate additional time for inspection.
