In a situation, where a problem has been found but its cause is still unknown, the background of the property, such as its renovation history and possible earlier fault situations, is investigated first. Buildings of the same age often have the same problems.

– Heat loss is surprisingly often due to a lack of sealing or insulation. Air conditioning systems often need adjustment, and areas in their original condition need a condition survey.

The site may have had water damage and/or other hidden structural problems that may only appear after a long time. In that case, a careful investigation should be conducted and the situation should be surveyed.

Problems should not be downplayed, because microbes or emissions of substances such as volatile organic compounds brewing up in the structures are hazardous to health.

Everyone benefits when the people paying maintenance charges, the users of the premises, the owners of the property and the personnel stay healthy, and the value of the property is preserved.

The investigation is conducted first, and then the engines start and potential hazards are removed.


In deodorisation, it is often necessary to use professional equipment. Depending on the situation at the problem site, we use deodorisation techniques of different levels after demolishing the damaged structures. Examples and more detailed information about the equipment can be found below.


The deodoriser is a plasma ioniser. Unlike ozone generators, it primarily produces singlet oxygen with only small amounts of ozone. This kind of active oxygen acts like ozone and is an effective oxidizer, but it is non-toxic!


Ions, or molecules or atoms with an electric charge, are produced in an ionisation process, usually with the help of a corona discharge. The actual ionisation is usually carried out in air purifiers and ionisers using ionising needles with high voltage. The process produces electrons that travel towards the head of the ionising needle through a closed circuit. As the electrons approach the head of the ionising needle, they are forced into a tight group. Because the electrons naturally repel each other, when they reach the head of the ionising needle, the pressure grows too high, causing them to “jump over” to the closest air molecule. When an electron becomes attached to a molecule floating in the air, it gives the molecule an electric charge, turning it into an ion.


Ozone consists of oxygen molecules with three atoms, while the oxygen molecules we breathe contain two atoms. Ozone is a powerful oxidant that destroys all known mould and yeast fungi as well as bacteria and viruses. Ozone is a harmful substance when inhaled, but when used correctly, ozonisation is safe. Ozone is generated for a certain time in the space to be treated; people should not stay in the space during treatment. However, they can quickly go in to turn off the ozoniser and open the windows. After a thorough airing, the space is ready for use.

Ozonisation is a safe and effective way to remove unwanted odours and allergens, such as the smell of tobacco, animals, mould, sewer and death, as well as a musty smell. Ozonisation removes unpleasant odours from dwellings, cars, caravans, boats, etc. Ozone does not contain any substances other than oxygen, and ozone treatment does not leave any traces of chemicals.


The disinfectant is spread into the indoor air or directly inside the structure with the Pulse Jet Fogger Patriot dry fog machine.

The dry fog machine produces a very fine aerosol fog of 0.5–50 µm.

The eponymous dry fog is indeed dry, which means that the method does not increase the moisture stress in structures. It penetrates the pores and cracks of structures effectively and destroys the mycelia and spores there.

As the fog spreads and descends on surfaces, it forms a thin, invisible chemical coating. This coating binds microbes and mould spores, which are then destroyed by the oxidation caused by the oxidants in the substance.


After renovation work at sites with indoor air problems, special cleaning of the structures and the repaired areas is recommended. Cleaning off dust from high levels, mould dust cleaning, fibre cleaning and special cleaning for various other fibres with the use of dust control methods form a large part of our operations.

Different kinds of hidden structures, such as the spaces above drop ceilings, should be checked and cleaned carefully, without forgetting air conditioning and other notable places on the premises, such as behind cupboards, etc.

For our equipment, we always use rated vacuum cleaners, negative pressure equipment and other dust control equipment, all of which has at least HEPA H13-rated filters.

As an example, our vacuum cleaners are M/H-class vacuum cleaners. We carry out special cleaning in a negative pressure enclosure, and if necessary, we partition the sections so that dust control and the clean and dirty sections are completely separate, which makes it possible to do the work safely.
