What happened
A 1970s extension was being stripped for replacement when ceiling tiles were identified as containing asbestos.
How it was discovered
The site foreman, sensibly, paused and called for a sample test. Result confirmed asbestos.
The consequences
Licensed removal contractor, site cleared, HSE notification, three weeks of delay, and a meaningful unbudgeted cost.
What homeowners can learn
Older properties carry asbestos risk. A pre-construction asbestos survey is cheaper than the discovery.
