INSPECTION & MAINTENANCE

Chimney inspection and maintenance has predominantly been the core business of the Company since its formation. Rafferty’s inspection and maintenance service applies sophisticated technical skills and visual evidencing techniques to assess the condition of any chimney whether brick, steel or concrete, irrespective of processing function. By adopting the philosophy of prevention being better than cure, a chimney that is regularly inspected and adequately maintained will remain a cost effective asset to the client.

As part of our chimney inspection and maintenance service, Rafferty’s also supply crucial servicing to lightning protection systems fitted to all types of industrial chimneys, ensuring that they meet the requirements of current standards.
