In a warehouse the challenge is the floor area, the height, and the fact that stock usually cannot be moved out.
Three conditions in a warehouse set the way the work is done:
Height also changes what has to be agreed. If the racking is six metres high, the treatment has to reach the top levels too — and the microclimate up there is different from the one at floor level: warm air rises, and condensation forms faster on the upper part of a cold external wall. So if you have mould on cardboard boxes on the top shelf but not on the bottom one, that is not a coincidence.
In a warehouse the treatment plan is built around the stock, not the other way round — and it is agreed before the visit, not on site.
| Type of goods | Action |
|---|---|
| Sealed goods | Usually can stay |
| Open food | Must be removed or covered |
| Cardboard packaging | Can stay, but we assess its moisture condition |
| Textile goods | Usually can stay — fogging does not damage them |
| Electronics | We cover them |
| Chemicals | Agreed separately |
The general principle: sealed goods are usually not a problem; open food and sensitive materials must be moved out or covered. We agree that before the work, not on site.
In practice things stall over three things. The first is open or part-opened food — it has to come out, and it is often only noticed on the day. The second is electronics and equipment: the forklift charging station, scanners, the office corner at the end of the warehouse — we cover those. The third is chemicals and materials that must not come into contact with the treatment product; where there are any, we agree them separately and sometimes exclude that zone from treatment.
The commonest reason a warehouse calls is not a hygiene requirement but a specific loss: cardboard has gone soft, patches have appeared on boxes, the stock smells of a cellar. The mechanism is usually the same. The external wall or the concrete floor is colder than the air, air exchange is poor, and moisture condenses on the coldest surfaces. Cardboard and wooden pallets absorb it and hold it for a long time.
Something practical you can do without us: pull the racking a few dozen centimetres away from the external wall so air can move behind it, and do not stand boxes directly on the concrete floor. In some warehouses that alone stops the problem recurring, and treatment is needed only once, to remove what is already there.
Who is ordering also shapes the conversation. If it is the company's own warehouse, the warehouse or logistics manager decides and the work can be scheduled quickly. If the space is leased in a logistics centre, the building's property manager gets involved too — particularly on ventilation, the roof and the alarm, which are not the tenant's responsibility. If the warehouse holds third-party goods, protection has to be agreed with the goods' owner as well, and that usually takes the longest.
The working window in a warehouse is usually the evening after the last despatch, or a non-working day. If the warehouse runs shifts, we use the gap between them, but bear in mind that for a large area, with contact time and airing, that can be too short. We calculate the exact time at the inspection — a figure quoted over the phone for a large area would be a guess.
Before fogging we agree the fire alarm: smoke detectors can react to fog, and it is the security company or the site's responsible person who disables it temporarily, not us. We also agree access and the doors regime — in a warehouse that is normally a security matter.
We assess the area, the height, how stock is laid out and the ventilation.
We settle protection of stock and the working time.
We cover electronics and agree disabling the alarm and access.
We treat the space with a cold or hot fogging machine.
The space stays closed for a set period.
We air the space and hand it back for work.
We prepare a document covering the work carried out.
Price in a warehouse is almost always a question of area, and it is on large areas that the rate per square metre is lowest. In practice that means there is little point treating a single run of racking on its own: setting up, positioning equipment and airing take nearly as long as doing the whole space. If the problem is local we say so, but it is usually better value to treat the whole zone in one go.
Seasonally, most warehouse calls come in spring and autumn. The reason is the same as in garages and basements: warm, humid outside air meets a structure that has not yet warmed up or has already cooled down, and condenses. If the cardboard in your warehouse turns damp in the same month every year, that is not a stock quality problem but a microclimate problem, and treatment removes the effect rather than the cause.
We do not move stock or unload racking — the site's own staff do that to our instructions. We do not do roof repairs, damp-proofing or ventilation installation. We do not take responsibility for goods the client has not identified as sensitive: that is precisely why the stock list and the protection plan are agreed in writing before the work. And we do not claim treatment will remove damp — if the cause is in the structure or in the air exchange, it stays.
100–300 m² — €0.90/m², 300–1000 m² — €0.70/m², over 1000 m² — by quotation after an inspection. For regular treatment we prepare a schedule and a quote.
In most cases no. Sealed goods can stay. Open food and sensitive materials are removed or covered — we agree that in advance.
Depending on the area and the method — usually a few hours, including contact time and airing.
Yes. On premises in the food chain we work to the applicable requirements: we document the treatment with a completion record, and surfaces that come into contact with food are rinsed afterwards.
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.
