Dealing with Dry Rot, Weston S Mare Refurb

Dealing with Dry Rot, Weston S Mare Refurb

The refurb of the flat is continuing with the eradication of the dry rot, the completion of the first-fix (before the plastering) electrics, and the building of false ceilings beneath the existing, to provide sound-proofing.

I use an unorthodox method to deal with dry rot, and link to my blog. The conventional method is to chop out the affected wood at lease a metre beyond visible infection, then saturate everything in chemicals. I used to do it this way, but there are problems in that the chemicals are very toxic and can be harmful to people. Also they don’t soak all the way into the wood, and dry-rot can be extremely persistent and make its way along the untreated core of the wood, avoiding the chemicals on the outside.

My method relies on the simple fact that all living organisms need water to survive. Dry Rot is a misnomer in that it needs to have its feet in water somewhere and requires conditions of quite high humidity to survive. But it is able to transport water from one place (such as a basement) over very long distances (such as to a roof). All I do is look for the source of the moisture and eliminate it. In this case it was a leak under the bath, and a soggy window sill below the rotten windows. The infection is now dead.

I’m not suggesting others try it, and I’m not sure if you can get guarantees with this kind of work. Until such guarantees can be obtained most people will unfortunately have to rely on the conventional chemical method.
