Our client thought she had dry rot in some wooden shelves mounted in the cellar of this Victorian brick-built house.

Observations by our surveyor concluded that there was no evidence of dry rot or wet rot, but as the cellar walls were below ground level and there was a previous case of dry rot in the property that the risk was significant enough to warrant treatment.

Works completed: 

External and internal observations from the free damp survey resulted in the recommendations as follows:

Client was asked to remove all furniture, floor coverings, radiators, power points and stored items from the cellar.

All further timber and materials were removed by us, within a metre of the suspected outbreak, and a toxic box was installed by drilling and injecting a masonry biocide into the walls and floors, where necessary.

In addition, an overspray of the biocide applied to the wall and floor to kill and contain any possible fungus to the area.

Fungal infestations cannot pass through the toxic box created and so contain the problem whilst killing the fungus if present in the area.

It is essential to address the root cause of the dry rot, and that the building is kept in a completely dry state and well maintained at all times.

Treatment – Note, the toxic box appears as routine series of holes
