Dampness and Timber Infestation Courses

 

All courses are now run by the Property Care Association in Huntingdon. 

 

They form the basis of the CSRT qualification which is nationally recognised: there are 3 modules to the qualification:

 

Dampness

Timber Infestation

Health, Safety and Law

The 2 modules that are given by Graham Coleman and their contents are listed below
