Sample reports
Anonymised, representative examples of reports produced by DampApp Pro and PropertySurvey Pro. All client details are removed.
Industry benchmarking
Aggregated, fully anonymised data from Pro subscribers who have consented to contribute to the benchmarking dataset. No survey, client, property address or surveyor identity is included.
Benchmarking dataset — building now
Pro subscribers can opt in to contribute anonymised finding data (defect type, severity, region). Once the dataset reaches statistical significance we will publish public aggregates here: most common defect types by region, severity distribution, and seasonal moisture trends.
Methodology: findings are stripped of all personally identifiable information before transmission. Aggregates are computed weekly and published only when each regional cohort contains ≥ 30 findings.
