Dry Rot Attack


 The initial enquiry from the owner of the property was in relation to a small area of fungus on the bedroom wall next to an exposed ceiling joist. This was a converted barn  that the owner was renting out to a young couple with a baby.


Apart from the fungal growth no other problems were obvious, however experience tells us that this is only the tip of the iceberg when dry rot is concerned. The removal of sections of plaster and floor boards revealed extensive damage to new chipboard flooring & batons, new timber stud walls and timber safe lintels extending approximately 4-5 meters from the first signs on the ground floor and up into the second floor by 2 meters.


The dry rot attacks have been caused in this situation by  a section of the external wall being saturated by a small undetected leak from a rainwater down pipe and  poor construction methods used by the contractor who had renovated the building only 6 years previously. Limited ventilation to unprotected wall and floor timbers have also contributed to the problem.


The treatment of the dry rot attacks where extensive, with external  timber wall linings being removed totally along with the entire area of the  floors in 3 rooms. Timber safe lintels where replaced with pre-stressed concrete lintels. Walls were drilled and sterilised along with floors, retained mid-floor joists were also drilled and injected with a fungicidal gel.  Mid-floor joist ends were  exposed and wrapped in a physical damp proof course.
Using treated timbers, all floors and walls were reinstated . Timber walls were  isolated from the external stone walls with breathable building membrane prior to being finished as requested by the client.

End Result

The client has been left with the peace of mind that the dry rot attacks have been  identified  totally and eradicated to a standard that can be guaranteed for 20 years.
