Hi Steve, Dang indeed. Thank you very much.
No we havent taken steps to sort anything with termites, they are present they have tried to eat bits and pieces but are kept at bay. unfortunately when we did the foundations I wasnt here to advise on that for a complete solution.
It can be done as a retro fit and we will think about it. All wood is old wood mostly Teak and very repellent or hard. There are 2 posts with termites in at the moment, one was white termites who eat surface layers and breed, but we have cut them out. The other couldnt find a way in but were sneaking up and around the front post of the house.
Everything is taken as it appears, i check on a regular basis but most posts are raised well away from ground level. We will see who wins!
