Animal odour and allergens soak into floor coverings, skirting boards and textiles. Washing the surface is rarely enough here.
After pets have been kept, three different things remain, and each needs a different answer:
This matters particularly if someone with allergies will be moving in: allergens persist long after the animal is no longer in the property.
Water does not dissolve urine residue — it reactivates it. That is why the smell is often stronger after a thorough wash, not weaker.
As urine dries it leaves crystalline residue. On its own that residue gives off little odour, but on contact with moisture it becomes active again. So "I washed it and it got worse" is not a misunderstanding — it is how it works. Damp weather, the heating coming on and summer warmth have the same effect.
That also explains why ordinary cleaning products work badly here. They remove what is on the surface, but the residue has soaked into joints, under the covering, into the underside of skirting boards and into the pores of the concrete base. While the residue is there, the smell comes back with every moisture cycle.
There is another reason the problem drags on: people look where they can see a stain, but an animal usually uses several spots, and some of them are behind furniture, behind doors and in corners. Treatment that only covers the visible stain gives a partial result, and the smell stays.
| Situation | Is surface treatment enough |
|---|---|
| Tiles, isolated spots | Yes |
| Laminate, liquid on the surface | Usually yes |
| Laminate, liquid under the covering | No — the covering has to come up |
| Carpet with backing | Rarely |
| Skirting boards and gaps | Often have to be removed |
| Upholstery | Ozone + surface treatment |
| Concrete base | Penetrating treatment needed |
A simple rule of thumb: if the smell is noticeable but the surfaces are clean, the liquid has most likely got under the covering or behind the skirting board. In that case surface treatment will hold for a few weeks.
In terms of price, that is the main difference. Surface treatment is quick work. Lifting the covering and the skirting boards and treating the base is a different scale of job, which is exactly why we set the exact price after an inspection rather than from a description over the phone.
We identify the affected spots — often they are not where the visible stain is.
We tell you whether surface treatment is enough or the covering has to come up.
We treat the affected spots with products that act on the source of the odour.
We treat upholstery, where allergens accumulate.
We treat the space, the ventilation and hard-to-reach places.
We air the premises and assess the result.
Finding the sources is the most important step, because that is where an incomplete result most often comes from. We look not just at the visible stains but also behind furniture, in corners, behind doors, along skirting boards, under radiators and around ventilation grilles. If animals were kept in the property for years, we also check the balcony or loggia covering, which is often forgotten.
Ozone is the closing step in this chain. It deals well with the odour left in the air, in textiles, in upholstery and in hard-to-reach places once the residues have been treated. Done before that, it masks the problem for a few weeks, and after the first damp day the smell is back.
If the animal still lives in the property, treatment is possible but its limits need to be understood: we can carry out surface treatment, animals must be out of the premises during ozone treatment, and while the animal stays the smell will gradually return. A full treatment makes sense when the premises are being prepared for the next occupants.
Allergens are a separate question, and a more important one than people usually assume. Hair and dander are very light particles that stay airborne for a long time and end up in textiles, upholstery, behind furniture, in the ventilation duct and in filters.
They persist for months after the animal has gone, so the question "the animal is not here any more, why is there still a reaction" is entirely reasonable. Treatment covering textiles, upholstery and the ventilation reduces the quantity substantially, but no method delivers complete absence — it is more honest to say so up front.
A concrete base is the worst case, because its pores absorb liquid deeply and it stays there even after the covering has been removed. Washing the surface is not enough — a penetrating treatment that acts inside the pore is needed, and the base then has to be dried before a new covering goes down. If that step is skipped, the new covering is laid on top of the source of the smell, and a few weeks later it starts all over again.
Flats from €55 depending on the number of rooms. Ozone treatment €1.20/m², minimum €60. If the covering has to be lifted or extensive surface treatment is needed, we set the price after an inspection.
It substantially reduces the quantity in the premises by treating textiles, upholstery and hard-to-reach places. No form of treatment can deliver a complete absence of allergens.
We can carry out surface treatment. Animals must be out of the premises during ozone treatment, and you should bear in mind that while the animal stays, the smell will gradually return.
Urine residue can give off odour for years, because it does not disappear on its own. That is exactly why it has to be eliminated rather than just washed over.
