The App for Ventilation & Mechanical Surveyors
In short
DampApp Pro is built for damp and timber professionals. It turns shorthand field notes into structured reports on-site, runs natively offline, and pairs airflow documentation with on-device psychrometrics for ventilation and IAQ work.
Identifying structural damp is only half the picture. For ventilation surveyors, mechanical surveyors and Part F compliance inspectors, evidencing inadequate airflow is central to addressing black mould.
Airflow & IAQ diagnostics
DampApp Pro bridges traditional structural surveying and mechanical ventilation analysis, supporting teams that carry out holistic property audits.
1. Part F documentation
Record extractor fan flow rates, trickle-vent presence and door undercut clearances directly in the app, and use AI Polish to draft clauses describing your ventilation findings, which you review before export.
2. Dew-point and humidity mapping
Enter dry-bulb and relative-humidity readings to calculate specific humidity and dew point, helping you show where condensation is likely to occur if ventilation is not upgraded.
3. Transparent pricing for audits
Whether you are a solo ventilation surveyor or part of an audit team, DampApp Pro is £74.99 per month or £749.99 per year (GBP), available worldwide with local currency and regional pricing shown at checkout.
Frequently asked questions
Can DampApp Pro support Part F ventilation surveys?▾
Yes. You can document extractor fan flow rates, trickle-vent presence and door undercut clearances directly in the app, and use AI Polish to draft clauses describing ventilation findings, which you review and edit before export.
What psychrometric values does it calculate for condensation?▾
From dry-bulb temperature and relative humidity, DampApp Pro derives dew point, vapour pressure and specific humidity in line with BS 5250 — helping you show where surface condensation is likely if ventilation is not improved.
Does it help link inadequate ventilation to mould?▾
Recording airflow observations alongside dew-point and humidity readings, and timestamped photographs (EXIF-derived where available), lets you present an evidence-based case connecting poor ventilation to condensation and mould growth.
Does it work offline during a mechanical audit?▾
Yes. Capture, psychrometric calculations and PDF report generation all run natively offline on the device, with data syncing and backing up to the cloud across your own devices when you are back in range.
What does DampApp Pro cost?▾
DampApp Pro is £74.99 per month or £749.99 per year (GBP), available worldwide with local currency and regional pricing shown at checkout. A free tier is available, and Pro adds a daily AI Polish allowance plus the option to use your own AI key.
