Professional Damp & Mould Survey Reports in Minutes, Not Evenings.

DampApp Pro was formerly published as DampSurvey Pro — same app, same maker (ProSurvey Apps Limited, company no. 17118570), now at dampsurvey.pro. We have no connection to the unrelated third-party website dampsurvey-pro.co.uk. See our naming clarification page at /dampsurvey-pro for the full history.

DampApp Pro helps housing associations and independent surveyors document damp and mould hazards against Awaab's Law timeframes. It records time-stamped reporting with EXIF-verified photo capture, building a clear audit trail for each tenant case.

Custom defect libraries map to rising damp, penetrating damp, wet rot, and dry rot assessments, giving surveyors RICS-aligned report clauses they can insert on-site.

Yes. DampApp Pro is built for damp and timber specialists. It works offline-first and uses AI report wording to generate professional PDF reports on-site, so sole traders can deliver reports the same day. Pro adds white-label branding with your own logo.

Yes. DampApp Pro is fully offline-capable, so surveyors can drop pins, take photos, and log defects deep inside basement properties with no cellular signal, then sync later.

You sign in with your account, so your surveys capture offline and then back up to the cloud and sync across your own devices the moment you reconnect to Wi-Fi. Start a survey on your phone in the field and finish the report on a tablet or at the desk, with your data safely backed up.

DampApp Pro includes an AI Polish module. Free users get a few trial runs to try it out; Pro unlocks a daily allowance through us, and you can add your own Google Gemini or OpenAI/ChatGPT API key for unlimited use. Type shorthand notes on-site and the AI expands them into structured report prose that you review and edit before export.

Yes, DampApp Pro features a sophisticated Internal Air Quality (IAQ) module. Surveyors can input temperature and humidity readings to automatically calculate precise psychrometric data, including specific humidity, vapour pressure, and dew points, natively offline.

Yes. We offer two free online calculators. The U-value & Interstitial Condensation Risk Calculator uses the steady-state Glaser method (ISO 13788 / ISO 6946) with live ERA5 climate data for any location worldwide and produces a professional PDF. The Enhanced Hygrothermal Calculator uses 8,760 hourly ERA5 data points and hygroscopic buffering — more accurate for borderline constructions. Both support multiple elements (wall, roof, floor), US imperial units, and require no login. Find them in the Tools menu above.

DampApp Pro natively integrates the OpenWeather API and RainViewer radar to fetch historical precipitation and atmospheric conditions on the day of the survey. This objective data can be embedded into the final report to substantiate penetrating damp and condensation analyses.

Yes. A Smart Builder engine lets surveyors select custom defect libraries tailored for heritage and commercial properties, adapting the workflow to specialised material degradation, basements, and complex structural decay not found in standard housing.

Yes. It helps landlords, property agents, and letting agents document structural damp issues and builds a time-stamped audit trail to evidence Awaab's Law compliance, now that Awaab's Law is being extended to the private rented sector under the Renters' Rights Act 2025.

Tradespeople and sole traders use DampApp Pro for offline-first reporting, which removes the need to write reports in the evening. Branded PDF output lets them hand a professional report to the client on the day of the survey.

A persistent musty smell is a primary indicator of mould growth or stagnant high moisture. If you also see water droplets on window frames, peeling wallpaper, or bubbling paint, it is likely a condensation failure. DampApp Pro logs temperature and relative humidity (RH), calculates dew points, and generates reports that help diagnose whether the smell is condensation or a structural leak.

Rising damp typically shows a 'tide mark' of salt stains or wet patches from the floor up to about 1 metre on internal plaster, whereas dry rot shows white, cotton-like fungal growth (mycelium) with cracking, crumbling timber. DampApp Pro lets surveyors log moisture profiles, drop timber defect markers, and produce technical remediation reports on-site.
