Different methods are being used in structure and condition surveys to define the building’s overall condition. We will define the content of the investigation on the basis of the subject’s special characteristics and, possibly, on the basis of the experienced symptoms.

After the subject’s investigations and analyzing of the results, a report will be made with proposals for further actions.


Good and healthy indoor air is a basic prerequisite for the well-being of the building users. Nevertheless, impurities often exist in the indoor air, which may cause different kinds of symptoms and health problems to users. There are several factors affecting indoor air quality, which is why the investigation plan of every subject will always be made case-specifically, and investigations are often implemented step by step.

The room temperature, lighting, air humidity, carbon dioxide concentration or room draftiness can, typically, have an effect on the quality of the indoor air. Gaseous or particle-like impurities can exist in the indoor air. Hidden defects, such as PAH compounds, hydrocarbon, formaldehyde or asbestos, can sometimes be detected from the indoor air.


Modern measurement methods and equipment guarantee the best results.



Our Building health experts lead indoor air investigations. An indoor air investigation or an investigation concerning suspected structural damage consists of several investigatory phases, of which the most common is sampling. We have modern measurement methods and equipment in use, with which we can implement large investigation entities professionally and cost-efficiently.


A condition assessment of a property will function as source information for the maintenance planning, and it provides valuable information to the owner of the property regarding the expectable needs of renovation and further investigation. A well-drafted condition assessment also provides valuable information on the total costs for the support of decision-making.

moisture surveys and moisture control

Moisture control is an important part in both the new settlement’s quality control and in the repair planning of the renovation subjects. With the help of our certified moisture meters of structures, as well as with our moisture control coordinator, the arising of, among others, indoor air problems and microbial damages caused by flood covering emissions can be prevented.

tightness measurements and marker tests

A tightness measurement is used in both new construction and in renovation subjects, when the purpose is to find out the air tightness of the structures and the location of the leaks. You will gain valuable information by using tightness measurement of the quality of the construction and possible construction defects. When potential air leaks are suspected, it is also possible to examine structures with marker tests. The tests include using a marker gas, which can be detected with an analyzer. The gas will be discharged into the structures that are being investigated.


A thermography applies very well for a new building’s quality control or for an older building’s repair needs and the mapping of damage structures. The thermography provides a clear picture of the thermal activity of the thermal activity of the structures. Thermal bridges and air leaks, for example, can be located cost-efficiently with the thermography.

radon measurements

Radon is an odorless, radioactive gas that is released from the soil and generally exist in indoor air. It is estimated that it causes ca. 300 lung cancer cases per year. In accordance with the Radiation Act 859/2018, among others, a radon measurement of indoor air is mandatory in several municipalities of Lapland. Our experts plan and implement measurements for both small and large subjects case-specifically.

A condition assessment is a basic tool for the controlled and planned maintenances and renovations of every housing cooperative.
