All our oak comes from sustainable resources in managed forests. The use of such timber is therefore more environmentally friendly than the use of other building materials.
Many oak framed buildings have lasted for hundreds of years, every bit as well as others of the same age built in stone or brick. We expect that one of our oak framed buildings, on a proper foundation, will last for many centuries with reasonable maintenance – oak itself requires little or no maintenance.
Oak is famous for its durability against rot and infestation, so we don’t recommend special treatments. Some people like to apply oak oil (boiled linseed oil) to their oak beams to slow up the drying process, but this is purely a matter of personal choice. Softwoods supplied by us are pressure treated against both rot and infestation but external timber will need maintenance during its lifetime.
