No exaggeration and no false reassurance — what is known about the effects of mould and what follows from it in practice.
Mould indoors releases spores and volatile metabolic compounds — the latter create the characteristic musty smell that is often noticeable before any patches appear.
International health bodies link damp and mould indoors with more frequent respiratory complaints, coughing, wheezing and worsening of existing asthma symptoms. People allergic to fungi may have more pronounced allergic reactions.
An important point: this is a question of association and increased risk, not a certain cause-and-effect in every individual case. Mould in a flat does not mean someone will definitely fall ill — and feeling unwell does not mean mould is the reason.
In Latvia, information on this subject is published by the Centre for Disease Prevention and Control.
What matters is not the size of the patch on the wall, but how long a person breathes in that room.
A practical order of priority follows from that. A patch of the same size in a child's room and in a basement corner is not the same situation: in the first case someone spends eight or more hours a day there, in the second a few minutes a week. So we always ask which room it is and who sleeps in it, not just how large the area is.
| Group | Why more sensitive |
|---|---|
| Infants and small children | Smaller airways, faster breathing rate, more time spent indoors |
| Older people | More frequent chronic respiratory conditions |
| People with asthma | Spores can worsen existing symptoms |
| People with allergies | Fungal spores are a common allergen |
| Weakened immunity | Particular caution is advised for patients under medical supervision |
That is exactly why mould in a child's room or bedroom has to be dealt with sooner than an equally large patch in a basement corner: what matters is how long a person spends in that room.
A bedroom is also the room where conditions suit the fungus best. At night the door is shut, the temperature there is usually lower than in the rest of the flat, and moisture from breathing enters the room for several hours. If the bed or a wardrobe also stands against an external wall, every factor lines up in one place.
There is also the opposite list — situations where there is no reason to rush. A small, freshly appeared patch on a bathroom silicone joint that cleans off and does not come back is not an emergency. Nor is an old dry water stain that is not growing. And a white crystalline film on basement masonry is not a fungus at all.
Before any treatment it is worth establishing two facts: how humid the air is and whether the ventilation works. You can check both yourself, and both change the solution.
If it turns out that humidity in the bedroom is consistently above 70% and the extract is not working, you already know the main thing. Often it is these two facts that decide whether treatment is needed or a change of routine will do.
If you have to choose where to start, the order is set not by the size of the patch but by how long a person breathes in that room.
That last condition matters. If a smell from a basement or loft reaches the flat through the stairwell or a shared ventilation shaft, it is no longer a distant space — its air is being breathed every day.
Several things coincide during the heating season. External wall surfaces cool down, so condensation mould grows precisely between October and March. At the same time windows are kept shut and airing happens less often, so it is not only moisture that builds up in the air but everything else released indoors as well. And people spend considerably more time inside in these months than in summer.
From that follows a practical recommendation that costs nothing: during the heating season, air short and hard — 5–10 minutes with the window wide open, several times a day. Cold outdoor air is dry, and once warmed indoors it can take up a lot of moisture. That is more effective and cheaper in heat terms than keeping a window ajar all day.
Our competence is treating premises, not medicine. In practice that means:
If someone in the household has asthma or allergies, say so when you get in touch. It affects which method we choose, how strictly we contain the affected room during the work, and how long the room has to be aired after treatment before going back in.
Inspection from €40, treatment from €1.50/m², minimum from €80. If someone in the household has a respiratory condition, mention it when you get in touch — it affects the choice of method and how long the room has to be aired after treatment.
In most domestic cases no — the response is the same regardless of species: remove the moisture and take out the affected material. Laboratory analysis is a separate service that makes sense in rare, specific cases.
It depends on the method. After surface treatment, airing the room is usually enough. After ozone treatment the room has to be left for a set period and then aired thoroughly — we give the exact time on site.
No, and no premises treatment company can. We can tell you whether there is mould in the rooms and what is causing it. Health is a conversation for a doctor.
Describe the situation — we will tell you whether treatment is needed at all, and which one.
Fill in the form — we will call you on the number you provide, ask a few clarifying questions and propose a solution.
Thank you! We will contact you on the phone number you provided shortly.
