Timber Treatment

Here at K.T. Preservation we have a passion for timber, it is one of the oldest and most widely used materials in construction and its use historically and within important buildings, means that we take pride and care in preserving pieces of the past. In this instance we have been surveying, repairing, preserving and treating timber as far back as 1984, to which we are graced to have been able to work in some of the most culturally and historically rich buildings, not only in Hampshire but in England. Timber is a very resilient building material which is backed up the fact, it remains tough and strong in some the oldest buildings in the world..
