FAQ - Häufig Gestellte Fragen

I own a house (with free attic) and I would like to check the state of the truss and possible order its protective treatment.

We can come to your house and inspect the truss. We will find out, if it has been attacked by any pest, or it is exposed to conditions which make it susceptible to a possible attack. Based on the diagnosed truss state, we establish the most appropriate way of treatment (particularly a suitable chemical agent). We calculate the price proposal for the treatment, the price is determined by the wood surface and by the employed agent. Die professionele Inspektion und Beratung an der Stelle ist kostenlos, die Anreisekosten hängen von einer vorherigen gegenseitigen Vereinbarung per Telefon ab.

I have an attic flat and I suspect the truss being attacked by woodworm / dry rot.

If there is an attic flat, most parts of the truss are not accessible and their possible treatment would require a decomposing intervention. It was a serious mistake, if the truss was not treated before the attic flat construction. Eventual treatment is only possible after disclosing the truss structure.

I am planning to build an attic flat - is there something to consider before?

The attic flat will isolate parts of the truss. Subsequently, the humidity can rise considerably in the insulated parts. High humidity is a key factor for the wood vulnerability to molds and funghi. For this reason, it is indispensable to treat the truss before the attic flat is realized. Once it is finished, parts of the truss are not accessible any more, and their posterior treatment is simply not possible. It is a rule (in our climate conditions) that an untreated wood behind the attic flat is almost immediately attacked. The cost of preventive truss treatment is negligible compared to to its eventual replacement or disassembly of the flat walls or roof in order to make it accessible.

I have a cottage, which is attacked by dry rot from the basement (wet walls, floors).

Dry rot can be very dangerous. First of all, it is necessary to barr further penetration of humidity from the ground to the floors and walls (there exist proven methods, and every experienced civil=engineering company should be able to implement them). At the same time, it is very convenient to chemically remove the red rot from the soil under the floors and the basement walls (we offer our professional services in this area). In case there are no funds for the civil-engineering action, the chemical treatment is much less expensive, but it has only a time-wise limited effect (it is necessary to repeat the treatment with 1 - 5 years period, depending on the local conditions and the state of the masonry).

I am building a house / cottage and I am aware of dry rot problems of other local residents.

In this case, it is very convenient to preventively treat not only the wooden truss, but also the basement hole and the basement masonry.

I have an antique piece of furniture, and I can hear a "crunchy" noise coming out - what can I do?

This could indicate a woodworm or a longhorn beetle living inside. In some cases, an effective treatment consists in repeated injection of chemical agent to the wood. We do not perform work of this type (given its size), but can give advice regarding the agent and the method.
