Treatment for Dry Rot on Log Cabin Walls
Dry rot in log cabin walls is generally treated by three methods. The choice of treatment depends on the extent of the damage:
1) If only a few logs are affected, they may be replaced by cutting out the logs and inserting new ones. This procedure, however, is not as straightforward as it seems. The logs are interconnected through matching contour surfaces or with splines in reglets that are destroyed during the replacement operation. It is impossible to reinsert the spines or match up the reglets unless the log is at a corner where the timber can be slid into place horizontally. So this can be tricky and should always be done by a professional.
2) Another repair procedure is to treat the decayed logs with an epoxy or petrifying compound. The timbers are injected with a compound that stops the rot and solidifies the decayed wood sections. This procedure has some drawbacks in terms of fire safety, longevity and insulation value. Epoxy and petrifying compounds are more flammable than heavy timbers. A preferred method of repair is log replacement.
3) The most radical treatment would be to shore up the roof and rebuild the walls. This alternative is however the least cost effective, but offers the best structure longevity.
