Timber Treatments

WJ Timber Treatments is one of the UK’s leading timber treatment providers. Our product range includes high and low-pressure preservative and fire retardant timber treatments, along with factory-applied timber coating systems. The company operates two primely-located treatment facilities and its very own kilning operation, specifically for drying treated and untreated timbers.



DeckWright is an innovative anti-slip solution that is applied to timber and composite decking grooves, either in our factory-controlled process or through the use of 1-metre insert strips, designed to be fitted to decking already laid. DeckWright greatly improves the safety of timber and composite decking, whatever the weather, and comes with a 5-year warranty.
