- From £135 inc VAT per home
- Charged visit, price agreed first

An indoor air quality survey measures how fresh and how damp the air in a building really is, over days rather than minutes. We place loggers that record CO2, humidity and temperature (and particulates in workplaces), then explain what the readings mean and what ventilation changes would help.
Our team is based in Great Barr, Birmingham, and we work throughout Tyne and Wear, from Newcastle upon Tyne, Sunderland, South Shields, Gateshead and Washington. Servicing, testing and repair visits are charged, and we tell you the cost before booking.

What indoor air quality surveys involves
CO2 is a practical indicator of whether a room is getting enough fresh air for the number of people in it: levels that climb steadily through a meeting or a night in a bedroom point to under-ventilation. Humidity readings show whether moisture is being removed or lingering long enough to cause condensation and mould. Surveys are useful before spending money: they show whether a problem is constant or happens at particular times, which rooms are worst, and whether an existing system is doing its job.
