Indoor air quality surveys in County Antrim

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 County Antrim, from Belfast, Lisburn, Newtownabbey, Carrickfergus and Ballymena. Because of the travel involved, visits here are by arrangement and travel is quoted before booking.

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.

Home survey

Loggers in bedrooms, living areas and wet rooms for 7 days, with a written summary.

Workplace survey

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

Before and after

Questions about indoor air quality surveys in County Antrim

Which towns in County Antrim do you cover?

All of County Antrim, including Belfast, Lisburn, Newtownabbey, Carrickfergus and Ballymena. If your town is not listed, send the postcode and we will confirm.

What is a good CO2 level indoors?

Outdoor air is around 400 to 450 parts per million; indoor levels that stay well below about 1,000 ppm usually indicate reasonable ventilation for the people in the room, while sustained levels much higher suggest it needs improving.

What humidity should a home be?

Relative humidity of roughly 40 to 60 percent is comfortable for most homes. Readings that sit above 70 percent for long periods make condensation and mould much more likely.

Are prices different in County Antrim?

Our guide prices are adjusted by region. In County Antrim we use Northern Ireland rates, so home air quality check: CO2, humidity and temperature logged for 7 days is typically £135 to £225 inc VAT per home.

Is the survey free in County Antrim?

Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.
