Mold inspection calculators

Free, no-signup field calculators for mold inspectors. Each one shows the formula it uses and cites the standards behind it — no thin widgets.

Air sample volume calculator

Flow rate × duration → liters and m³ sampled, flagged against the typical spore-trap range.

Indoor:outdoor ratio calculator

Indoor ÷ outdoor spore count → the ratio an air sample is read by, interpreted directionally.

Dew point & condensation risk

Temperature + RH → dew point, flagging condensation and mold-growth risk on building surfaces.

Inspection pricing estimator

Job size + sample count → an estimated client fee range, with the market sources cited.
