Indoor air quality surveys in Lancashire

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.

We carry out indoor air quality surveys across Lancashire, including Lancaster, Lytham St Annes, Preston, Burnley and Blackburn. Prices use North West rates. Visits for this work are charged, with the price agreed before we arrive.

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.

Workplace survey

CO2, humidity, temperature and particulates in offices, classrooms or meeting rooms.

Before and after

Readings taken before and after a ventilation upgrade to show the difference.

Spot checks

Readings taken during a single visit, where a quick answer is enough.
