When placing an order, you understand the inherent properties of timber which will affect your timber product to a lesser or greater degree:

Timber is a natural product and prone to changes in appearance, including some movement and the occurrence of small knot holes or splits in extreme temperatures and weather conditions. Any splits, knots or similar visual imperfections in the timber will not affect the structural integrity of the product in any way, are not considered to be damage, and do not render the product unfit for purpose. Whilst every effort is made to hand pick timber without visible knotholes or splits there may be occasions where timber is selected in good faith that contains what appears to be a solid knot. Over the course of time / during movement of the product etc it may occur that these small knot holes are then dislodged from the timber leaving a small knot or crack. Unfortunately, we cannot be held responsible for this maturing of the product and can only offer our best advice as how to deal with this situation in the unlikely event that it should occur. When measuring timber for the purpose of technical information the absolute external dimensions will be taken from a sample piece of each component used – it should be noted that due to the complex nature of the product and machining processes that this figure will give an average measurement that could be subject to slight variance throughout the rest of the individual boards in the pack measured. Whilst every effort will be made to select only components which match the average advertised sizing this is subject to the availability of the timber that has been machined and cannot be guaranteed.
