Sigma Plantfinders Experience

Sigma Plantfinder Limited are a global exporter of machinery for the construction industry with over 40 years of experience. First, the original partnership – James and Sons was formed in Bristol in 1975 and in 1994 the business decided to relocate to Stokesley, North Yorkshire and continued trading as James of Stokesley.

In 2007 the significant growth of the export division resulted in the company getting additional premises in John Boyle Road, Middlesbrough where Sigma Plantfinder operates today. In August 2014 the business was incorporated and now trades as Sigma Plantfinder Limited.
