Training Courses for Surveyors
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
