We recommend that you should always factor in extra wood for waste when installing a floor. The amount of waste you need to allow for will vary according to the type of floor you are ordering, the shape of your room and the skill of your fitter. We normally recommend ordering 10% more than your actual square meterage for waste when using standard planks and 15% for parquet blocks, but this is something you and your installer must decide. Bear in mind that it is a good idea to keep a few extra planks once the floor has been installed in case you ever need to replace a damaged board.If you do not order enough wood you may delay your installation and may find that there is more colour variation in wood ordered subsequently as it will come from a different batch.
