Manufactured by Chemfix Products Ltd. Timbabuild is a 2-part filler, timber repair system in a cartridge, created in 1998 by Nickerson Chemicals after demand for a heavy duty wood repair product designed specifically for a large scale renovation and repair project by Leeds City Council. After the project saved thousands of pounds repairing rotten windows, doors and more, in situ, rather than replacing with new units, the Timbabuild system was then manufactured as a range of products, which we have stocked here for many years now.
