Dry Rot Treatment
In any case, where dry rot is discovered, the badly decayed wood which is beyond repair should be removed and disposed of as a first action. When cutting away affected wood, it’s good practice to remove at least 600mm past the affected area(s) to ensure that all the decay is removed.
Any wall plaster which shows signs of decay should also be removed. In cases where it is not possible to treat the full extent of the outbreak on a wall (either because of the extent of the outbreak penetrating the wall or because the wall’s construction does not lend itself well to treatment), then a toxic barrier or irrigation of the wall may be preferable to starve the outbreak of a water supply. Once this is done, we use the ALLDAMP Dry Rot Solution to treat the affected areas which will kill any remaining dry rot fungus. Additionally, use of this Solution, prevents any future spread of the decay. Any timber used for replacements should be pre-treated against fungal decay.
The above assumes that the cause of the damp which led to the dry rot outbreak has been cured. For more information on our damp proofing services, visit our damp proofing page.
