DampApp Pro
DampApp Pro gives damp and timber surveyors a native mobile app for capturing rising damp, penetrating damp, condensation, woodworm, dry rot, and mould on site, then exporting branded PDF reports before leaving the property. Core surveying, psychrometric calculations, and PDF rendering run fully offline on your phone or tablet, so basement inspections do not depend on a signal.
Most damp survey apps are cloud wrappers that stall without connectivity. DampApp Pro is built as a native offline-first tool for independent surveyors and small firms, with optional AI Polish that expands shorthand notes into editable, standards-aware report text through Google Gemini or OpenAI. ProSurvey Apps also offers HousingSurvey Pro for housing associations that need enterprise case management rather than one-off survey reports.
Independent damp surveyors, damp proofing contractors, housing associations instructing external surveyors, landlords, and letting agents use DampApp Pro for structured mould inspections, HHSRS evidence, and Awaab's Law documentation. The free tier stores up to 25 surveys on device with watermarked PDFs, while Pro adds cloud sync for up to 5,000 active surveys, white-label PDFs, and higher AI allowances.
