What the survey can do
The surveyor can comment on accessible materials that appear consistent with products historically associated with asbestos and explain why further investigation may be sensible.
What it cannot confirm
Visual inspection cannot establish whether a material contains asbestos. Confirmation requires appropriately managed sampling and analysis by a competent specialist.
Before alteration work
If refurbishment or demolition is planned, seek the appropriate specialist advice before disturbing suspect materials. The type of assessment needed depends on the building and intended work.
