 St Helens College appointed TCM in July 2008 for the purpose of eradicating Japanese knotweed from areas of our Newton Campus. 

Throughout the contract TCM demonstrated an expertise and resource which was to be admired.  I was particularly impressed with the ongoing monitoring of the treated areas until TCM were satisfied that eradication was successful and the guaranteed issued.

On behalf of St Helens College I would strongly recommend TCM to any prospective client involved with the eradication of Japanese knotweed and I would be pleased to discuss any particular points of detail with any organisation should this be considered helpful.  John Frodsham, Assistant Principal: Facilities
