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.
Across Highland and Moray the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Nairn, Inverness, Elgin and Fort William.
Jobs in the remote Highlands and on the islands are by arrangement, with travel quoted in writing before you commit.

How we do it
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.
