Indoor air quality surveys in West Midlands

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.

Every job in the West Midlands gets a written quote before it starts and a commissioning record when it finishes. We cover Dudley, Walsall, Solihull, Sutton Coldfield and West Bromwich and the villages around them.

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.

Spot checks

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

Home survey

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

Questions about indoor air quality surveys in the West Midlands

Which rules apply to ventilation in the West Midlands?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.

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.

Which towns in the West Midlands do you cover?

All of the West Midlands, including Dudley, Walsall, Solihull, Sutton Coldfield and West Bromwich. If your town is not listed, send the postcode and we will confirm.

Are prices different in the West Midlands?

Our guide prices are adjusted by region. In the West Midlands we use West Midlands rates, so home air quality check: CO2, humidity and temperature logged for 7 days is typically £145 to £245 inc VAT per home.
