How we write these
Everything here is written by people who do the work, and reviewed against what we actually see on jobs in this town. Where a figure is sourced — the 24 to 48 hour mold window from EPA and IICRC guidance, per-square-foot mitigation ranges, the Lafayette Reservoir history — we say where it comes from. Where a figure is not reliably available, such as a gray water per-square-foot range, we say that too rather than inventing one.
