Air Quality Monitoring

An air quality monitor is a set of devices that uses sensors to detect, monitor, or report on diagnostics such as temperature and humidity levels to understand any issues.

Rentokil Property Care can then use the findings from the devices to manage and prevent condensation issues based on the information found. The sensors are placed around the property, typically in condensation hotspots such as bathrooms, bedrooms and cold north facing rooms.

This will also highlight areas of concern, where moisture levels are higher than normal.

Our professionally qualified damp surveyors can then use diagnostics such as humidity levels and temperature to identify any areas of concern.

It is estimated that over 839,000 homes suffer from damp problems in the UK. ( English Housing Survey 2020-2021 ).

Excess moisture is created in homes, simply from everyday living such as cooking and cleaning. Moisture levels will normally remain in the atmosphere if inadequate ventilation exists. When temperatures drop, it becomes more difficult for air to hold the moisture. This means that the air becomes saturated, and the excess moisture will land on cold spots around your home, such as walls or ceilings. This is how condensation occurs, and can lead to unsightly symptoms such as black mould.

Air monitoring will collect data in the property over a period of time, which is then input into a software system that can analyse, interpret and visualise the data into an indoor air quality report.

This helps create a visual representation of the problem which can then be used by our surveyors to make recommendations.

Government guidance in 2023 ( Understanding and addressing the health risks of damp and mould in the home ) offers advice to landlords on how to tackle condensation and damp problems. The guidance states landlords should consider “forms of physical testing, such as thermography” and “environmental monitoring” for complex cases of damp and condensation. This can be used to identify root causes of damp problems in rental properties.

The report also states that “smart sensors may be a useful aid to monitor temperature, humidity and indoor air quality and to identify at-risk properties” (Understanding and addressing the health risks of damp and mould in the home, 2023).

It is recommended that the system be left in place for a minimum of one to two weeks. Condensation issues can occur at different times of the day, and can vary from household to household. Leaving the system in place for one to two weeks will allow it to produce an appropriate amount of data. Our damp surveyor will attend the property and install the air quality monitoring system. After an agreed time period, the surveyor will return to collect the devices and complete a property survey which will be used in conjunction with the data found.

Our indoor air quality system uses SmartLink technology. This technology uses long range and low power connectivity between the main Hub and monitoring devices. The hub must remain plugged into the mains at all times. This allows it to connect and gather real time data from with the battery operated monitoring devices.

The data collected will be input into a software system. This system creates an indoor air quality report by analysing, interpreting and visualising the data. Our damp surveyor can use the findings of the report to understand what, if any, damp or ventilation issues are present in your property.

As well as the indoor air quality report, our surveyor will complete a comprehensive condensation survey of the property. Following the survey, our surveyor will send you a detailed and thorough report on the findings, specifically tailored to your property.

This damp report will be presented in an easy to understand format. If necessary, the surveyor will include recommendations for any further measures. Measures to help tackle a ventilation problem could include the installation of (positive input ventilation) PIV units, extractor fans, insulation installation or thermal plastering.

Our fully trained and qualified surveyors have decades of experience finding the source of condensation problems, and offering solutions.
